2.6.22-rc6-mm1

[Andrew Morton]

ftp://ftp.kernel.org/pub/linux/kernel/people/akpm/patches/2.6/2.6.22-rc6/2.6.22-rc6-mm1/

- NOTE (an uppercase one, indeed): there are a lot of menuconfig changes in
here which break `make oldconfig' badly. If you grab an old .config and run
`make oldconfig', your kernel probably won't work. I lost useful things
like CONFIG_BLK_DEV and the whole SCSI system, because they were added after
I generated my .config.

So save yourself some hassle and check your .config carefully before
building this kernel. Make sure that everything you need is still enabled.

I found that manually adding "CONFIG_BLK_DEV=y" to the .config before
running oldconfig saved a large number of config items from getting lost.

Those menuconfig changes have been a huge pain.

- Added the kgdb tree, as git-kgdb.patch (Jason Wessel
<***@windriver.com>)

This is a large patch which unifies all the various kgdb stubs lying
around various architectures and extends kgdb support to other
architectures. Supported architectures are at present arm, i386, ia64,
mips, ppc32, ppc64, sh, and x86_64.

Subject to review, we're aiming this at 2.6.24.

- Jean's hwmon git tree was dropped and was replaced by the new
git-hwmon.patch (Mark M. Hoffman <***@lightlink.com>)

- Added new git-ixgbe.patch: "10GbE driver for Intel 82598 based PCI Express
adapters" (Ayyappan Veeraiyan <***@intel.com>)

- I cannot persuade git to generate a sane diff out of git-wireless, so it
is dropped. Which is bad, because it contains a tremendous amount of stuff.

- Added x86_64 dynticks support

- Merged the dynamic commandline length patches - these remove Linux's
hard-coded limit.



Boilerplate:

- See the `hot-fixes' directory for any important updates to this patchset.

- To fetch an -mm tree using git, use (for example)

git-fetch git://git.kernel.org/pub/scm/linux/kernel/git/smurf/linux-trees.git tag v2.6.16-rc2-mm1
git-checkout -b local-v2.6.16-rc2-mm1 v2.6.16-rc2-mm1

- -mm kernel commit activity can be reviewed by subscribing to the
mm-commits mailing list.

echo "subscribe mm-commits" | mail ***@vger.kernel.org

- If you hit a bug in -mm and it is not obvious which patch caused it, it is
most valuable if you can perform a bisection search to identify which patch
introduced the bug. Instructions for this process are at

http://www.zip.com.au/~akpm/linux/patches/stuff/bisecting-mm-trees.txt

But beware that this process takes some time (around ten rebuilds and
reboots), so consider reporting the bug first and if we cannot immediately
identify the faulty patch, then perform the bisection search.

- When reporting bugs, please try to Cc: the relevant maintainer and mailing
list on any email.

- When reporting bugs in this kernel via email, please also rewrite the
email Subject: in some manner to reflect the nature of the bug. Some
developers filter by Subject: when looking for messages to read.

- Occasional snapshots of the -mm lineup are uploaded to
ftp://ftp.kernel.org/pub/linux/kernel/people/akpm/mm/ and are announced on
the mm-commits list.

[Heiko Carstens]

From: Heiko Carstens <***@de.ibm.com>

check_signature() uses readb() and therefore should only be build on
CONFIG_HAS_IOMEM.

Otherwise breaks s390:
lib/check_signature.c: In function `check_signature':
lib/check_signature.c:19: error: implicit declaration of function `readb'

We didn't think of that.

Alas, m68k `make allmodconfig' creates CONFIG_ISA=n, CONFIG_PCI=n,
CONFIG_HAS_IOMEM=y, so it will still be busted.

But this seems to be the correct fix. Perhaps m68k config needs
attention?

attention?

Euh, I don't think this is the correct fix.

CONFIG_HAS_IOMEM is apparently used in two meanings:
1. The architecture has support for memory mapped I/O (s390 obviously
hasn't)
2. The architecture has ISA/PCI-style memory mapped I/O (readb() and
friends)

check_signature() falls under the second category.

Setting NO_IOMEM on m68k will make us loose some drivers (e.g.
drivers/video/Kconfig depends on HAS_IOMEM).

Apart from many Kconfig dependencies on HAS_IOMEM, CONFIG_HAS_IOMEM is
further only used to control the build of lib/iomap_copy.c, which
doesn't use readb() and friends, but the __raw*() operations.

There already exists a CONFIG_HAS_IOPORT :-) (for ISA/PCI-style I/O port
access).

Just make check_signature() depend on ISA || PCI (and maybe || X86_32).
According to its comment, it's used to `find BIOS signatures', which is
a legacy PC thing. Please don't pollute non-legacy architectures with it ;-)

check_signature() needs readb() but with some setups (s390, m68k allmodconfig)
there is no implementation of readb. This causes build errors with
-Werror-implicit-function-declaration.

So make check_signature.o dependent upon ISA||PCI.

check_signature() needs readb() but with some setups (s390, m68k allmodconfig)
there is no implementation of readb. This causes build errors with
-Werror-implicit-function-declaration.

This completely bogus. readb() should be present on M68K, fix the
platform to implement readb() for MMIO, even if your MMIO readb is a
moveb instruction.

check_signature is relevant for anything with MMIO space (for example you
can legitimately want to check_signature a MAC68K Nubus ROM).

S/390 is a bit of a special case as no S/390 usage of check_signature
appears sane but equally it isn't used so you can stub it out.

This is a problem for UML too.

I have a patch in my tree, which basically stubs readb, waiting to see
how this is fixed for the other arches.

What a mess.

I guess we could add an empty readb() implementation to lib/lib.a so the
arch will pick that up if all else fails. But it's pretty stinky. And
it won't work either because we don't know at compile-time to declare
the prototype for that thing appropriately.

So... what's the proper fix here? "The arch must implement readb"? That's
bad: if the arch really cannot implement readb(), we want builds to fail
if someone tries to use it.

I think I'll go shopping instead.

Does M68K implement iomap() and pci_iomap and friends yet ?
check_signature has fairly few users so moving to be iomap based wouldn't
be hard if that was a problem. The other option would seem to be
bus->check_signature() ?

IMO the first question would be whether that function is really this
important. We can also just leave it as a PCI/ISA template and other bus
specific header can implement when necessary.

check_signature is relevant for anything with MMIO space (for example you

To make it more generic, it should probably use the raw*() version, and
the caller should handle bus address conversion. But even that
isn't possible, as there's no guarantee readb(x+1) == raw_readb(x+1).

Anyway, here's a list of its users, as I responded to Andrew in a private
mail before this thread was started:

| drivers/block/xd.c: config BLK_DEV_XD depends on ISA && ISA_DMA_API
| drivers/input/misc/wistron_btns.c: config INPUT_WISTRON_BTNS depends on X86 && !X86_64

That should be X86_32 these days?

| drivers/scsi/aha152x.c: config SCSI_AHA152X depends on ISA && SCSI && !64BIT
| drivers/scsi/dtc.c: config SCSI_DTC3280 depends on ISA && SCSI
| drivers/scsi/fdomain.c: config SCSI_FUTURE_DOMAIN depends on (ISA || PCI) && SCSI
| drivers/scsi/seagate.c: config SCSI_SEAGATE depends on X86 && ISA && SCSI
| drivers/scsi/t128.c: config SCSI_T128 depends on ISA && SCSI
| drivers/scsi/wd7000.c: config SCSI_7000FASST depends on ISA && SCSI && ISA_DMA_API

BTW, include/asm-arm/io.h looks interesting:

| #elif !defined(readb)
|
| #define readb(c) (__readwrite_bug("readb"),0)
| #define readw(c) (__readwrite_bug("readw"),0)
| #define readl(c) (__readwrite_bug("readl"),0)
| #define writeb(v,c) __readwrite_bug("writeb")
| #define writew(v,c) __readwrite_bug("writew")
| #define writel(v,c) __readwrite_bug("writel")
|
| #define check_signature(io,sig,len) (0)

Hm. Those are false alarms. I guess I could do something to hide them,

Is there someway to whitelist them?

The Xen code generates some abs symbols which are OK from a relocation
perspective.

Actually I have to ask. How in the world are these absolute symbols
ok from a relocation perspective.

If the kernel is not running at 0xc0100000 the offset value looks like
it will be completely bogus.

Maybe those are ok, but if you could please explain why those are
false positives I would appreciate it. (Especially in your patch
description).

If these are indeed false positives the patch looks ok.

Subject: xen: suppress abs symbol warnings for unused reloc pointers

arch/i386/xen/xen-asm.S defines some small pieces of code which are
used to implement a few paravirt_ops. They're designed so they can be
used either in-place, or be inline patched into their callsites if
there's enough space.

Some of those operations need to make calls out (specifically, if you
re-enable events [interrupts], and there's a pending event at that
time). These calls need the call instruction to be relocated if the
code is patched inline. In this case xen_foo_reloc is a section-relative
symbol which points to xen_foo's required relocation.

Other operations have no need of a relocation, and so their
corresponding xen_bar_reloc is absolute 0. These are the cases which
are triggering the warning.

This patch adds those symbols to the list of safe abs symbols.

Intel IOMMU support

I believe the above patch set is causing the problem. On my first try
with rc6-mm1 I said Yes to the CONFIG_DMAR options. (I'm nearly as good
as random option selection :-)

The system panicked during boot, I believe it was trying to detect an
Intel IOMMU. Later when I have a camera, I will try to post a
screenshot of the backtrace. (I can't seem to get netconsole to work on
boot, only in a module).

When I recompiled without DMAR set, things seem to be working great. I
seem to be getting better disk read throughput than rc3-mm1, by the way.

This laptop is an AMD Athlon64 on a NForce3 running a 64-bit Gentoo
build.

I'll provide more details on request, and when I get the chance. This
is a heads-up on the BUG in case someone has an "ah ha!" moment.

I'll provide more details on request, and when I get the chance. This
is a heads-up on the BUG in case someone has an "ah ha!" moment.

I believe I have also reproduced this bug. I have an ABIT K9 Ultra
motherboard with NFORCE hardware. My serial console cannot
seem to capture it, but removing the DMAR options definately takes
away the problem and allows me to boot.

If anyone would like me to gather other info or test out patches,
please let me know.

Intel IOMMU support

I believe the above patch set is causing the problem. On my first try
with rc6-mm1 I said Yes to the CONFIG_DMAR options. (I'm nearly as good
as random option selection :-)
The system panicked during boot, I believe it was trying to detect an
Intel IOMMU. Later when I have a camera, I will try to post a
screenshot of the backtrace. (I can't seem to get netconsole to work on
boot, only in a module).
When I recompiled without DMAR set, things seem to be working great. I
seem to be getting better disk read throughput than rc3-mm1, by the way.
This laptop is an AMD Athlon64 on a NForce3 running a 64-bit Gentoo
build.
I'll provide more details on request, and when I get the chance. This
is a heads-up on the BUG in case someone has an "ah ha!" moment.

I took a picture of it, looks like the backtrace is:

NULL pointer dereference at 024
EIP:dmar_table_init+0x11
intel_iommu_init+0x30
pci_iommu_init+0xe
kernel_init+0x16e

Presumably something is NULL in dmar_table_init that wasn't expected to
be.. I would guess it likely crashes on any system without an Intel
IOMMU in it.

Since this is IOMMU is built into the kernel and it is
good idea to report that the device is not present. The
above is printed only once and is consistent with other
IOMMU implementation. Atleast it is useful when people
report bugs we can makeout whether IOMMU is being detected

Yes - as a debug message.

If it was printed that it was detected it was - otherwise, it wasn't.

"PCI-GART: No AMD northbridge found."

You're right, that should be a debug message as well.

These are KERN_DEBUG messages.

allmodconfig on powerpc (iMac g3) fails due to

anyway after unselecting XMON we can see:

I'm not sure if this will work out but maybe it's worth to disable XMON if
KGDB is selected, like this?

Hi,

Post by Andrew Morton
So save yourself some hassle and check your .config carefully before
building this kernel. Make sure that everything you need is still enabled.
I found that manually adding "CONFIG_BLK_DEV=y" to the .config before
running oldconfig saved a large number of config items from getting lost.

This patch should help for this, so that this isn't done when Kconfig or
.config has been changed and they are not in sync.

bye, Roman

unclear. Could you please explain further what this change does?

Normally generated values (Kconfig entries without a prompt) are cleared
as they are regenerated anyway and so they appear as new should they
become visible and defaults work as expected (once a value is set defaults
aren't used anymore).
The detection whether a value is generated or not is only based on its
visibility status, which can quickly change for a lot of symbols by just
removing a single line from .config or adding a dependency to Kconfig as
you noticed.
The patch now suppresses this logic when .config and Kconfig aren't in
sync and .config needs to be updated, so that you can remove now a random
value from .config and oldconfig won't reask for many other values.

bye, Roman

`make oldconfig', your kernel probably won't work. I lost useful things
like CONFIG_BLK_DEV and the whole SCSI system, because they were added after
I generated my .config.

Odd - just for grins, I checked what 'make oldconfig' did when handed a .config
from 22-rc4-mm2, and it behaved just fine, much to my surprise.

I can't comment on the DMAR issues, my .config didn't include PCI_MSI so I never
got asked about that one by oldconfig. Maybe if I get brave this afternoon. :)

That's probably because your old config file was relatively recent, and
had things like CONFIG_BLK_DEV=y in it.

But those people who are still dragging around old config files which
predate the introduction of CONFIG_BLK_DEV will find that 2.6.22-rc6-mm1
oldconfig will give them CONFIG_BLK_DEV=n instead of current mainline's
deafult of CONFIG_BLK_DEV=y.

I think making BLK_DEV deafult to n was a bit dumb, so I dropped the
offending patches.

Ahh... <light bulb goes on> Yeah, it gets a 'make oldconfig' for pretty
much every single -mm, I suck at any regression testing other than "since
the last -mm".

from 22-rc4-mm2, and it behaved just fine, much to my surprise.

That's probably because your old config file was relatively recent, and
had things like CONFIG_BLK_DEV=y in it.

Ahh... <light bulb goes on> Yeah, it gets a 'make oldconfig' for pretty
much every single -mm, I suck at any regression testing other than "since
the last -mm".

All my .configs have mouldered since I lost the ability to have .config be
a symlink to a revision-controlled file (used to carry a custom patch for
this, but it died).

I continue to believe that kbuild's lets-trash-your-symlink behaviour is
obnoxious, but I was unable to persuade anyone else of this.

That's pretty awful, but it hasn't really affected me much since I
started using separate object directories for pretty much everything.

In the unlikely event that I recall it I will take a look when I'm back.

By the way - kbuild.git is lacking behind on patches.

Nope, a simple `make oldconfig' breaks the symlink.

Nope. I usually does not include section mismatch fixes in the kbuild.git

This patch should go in via SH maintainer since this is sh specific

The preferred way is to push static functions' definitions above the
callsites (caller functions) in the same file, if possible.
Perhaps Adrian was in a hurry so didn't do that ...

It might have even been me who said this - but about global functions.

For global functions, prototypes in header files allow gcc to check
whether the prototype matches the actual function. With a prototype
in the C file of the caller that's not possible, and if they are
different it can result in nasty runtime errors.

For static functions that's not an issue since gcc sees both the
prototype and the actual function.

The following doesn't make much sense:

tristate "TEA 5761 radio tuner (EXPERIMENTAL)"
...

drivers/media/video/Makefile:
...
ifneq ($(CONFIG_TUNER_TEA5761),)

endif
...

With this setup, TUNER_TEA5761=m is equivalent to TUNER_TEA5761=y.

This patch therefore changes TUNER_TEA5761 to a bool.

The missing dependency on EXPERIMENTAL the prompt text indicates also
gets added by this patch.

Additionally, the Makefile entry can now be written in a more compact way.

Xen currently relies on contigious memory (ie, no numa, discontig or
sparse memory). Specifically it uses mem_map, which is only available
if CONFIG_NEED_MULTIPLE_NODES is not defined.

This is a large patch which unifies all the various kgdb stubs lying
around various architectures and extends kgdb support to other
architectures. Supported architectures are at present arm, i386, ia64,
mips, ppc32, ppc64, sh, and x86_64.
Subject to review, we're aiming this at 2.6.24.

Built a kernel with this just for fun on a Pentium D 940 system running

hm. It _looks_ like kgdb hasn't been told the uart address and it's
defaulting to something silly. But a) it should guess better than that and
b) the addresses should differ at least a little bit.

Maybe Jason can tell us what went wrong?

- Added the kgdb tree, as git-kgdb.patch (Jason Wessel
This is a large patch which unifies all the various kgdb stubs lying
around various architectures and extends kgdb support to other
architectures. Supported architectures are at present arm, i386, ia64,
mips, ppc32, ppc64, sh, and x86_64.
Subject to review, we're aiming this at 2.6.24.

Built a kernel with this just for fun on a Pentium D 940 system running
a 32 bit install of SuSE 10.2. It complained thusly relatively early

Hi Tilman,

Perhaps you could send me your entire .config as well as the entire
output of the dmesg after your boot, or the entire boot log?

One of the kgdb patches does slightly modify the rs232 registration. If
your system did not have a second serial port, or if the virtual second
line is some kind of other device that "simple configuration" detect
needs further modification. Hopefully the full output of the boot will
shed some light as to what is going on.

Thanks,
Jason.

I didn't even try to actually do anything with kgdb, though.

Do you have something that is more than subjective as a measure? Some
app runs slower, or it boots x seconds slower?

The only place I could foresee that kgdb could be eating extra cycles in
the runtime case is from the die_notifier processing. Any kind of
exception such as a page fault, trap etc... will have a few extra ops
and checks of variables so as to determine if the debugger should take
the exception. It looks to me like it would even benefit to add the
check at the top of the notify hook for kgdb to exit immediately if the
debugger is not attached.

I have contemplated making some changes to KGDB so as to make the
registration to the die_notifier to be dynamic with attaching and
detaching of the debugger. If this is done, I would also make a change
to allow for the case where the kernel would wait for the debugger to
attach on any fatal fault.

Jason.

At this chance... Reminds me that this old issue still seems to be
unsolved in current kgdb:

http://www.mail-archive.com/kgdb-***@lists.sourceforge.net/msg00442.html

I'm only looking at that spot in kgdb right now and /may/ oversee new
border conditions elsewhere. But my feeling is there are none.

Hi Jan,

This issue was fixed in a generic way in the patch set that is in the
-mm tree. Had you tried your test case in the current -mm tree?

The problem you mentioned was fixed by saving and restoring the preempt
count as a part of the fault handling from the kgdb core and not in the
arch specific portion.

Jason.

Nope, I have unfortunately no adequate test setup at hand right now.

Ah, OK, that was the piece I missed.

Then /me is just curious to finally learn why that hack I once proposed
(which unfortunately never received some feedback) is not the right way
to go. In other words, what is the reason for this special
fault_setjmp/fault_longjmp?

Another problem with this patch are the added inline's:

gcc already automatically inlines static functions with only one caller=
