Since 97965478a66fbdf0f4ad5e4ecc4828f0cb548a45 ("mm: Get rid of __ZONE_COUNT")
mmzone.h includes bounds.h.
Calling make clean after make prepare removes bounds.h
again so when building external modules this fails.Signed-off-by: Jan Blunck

1) The field 'len' of the 'gstr' structure seems to track the size of the memory
already allocated for the "growable string". So the value of this field should be
the same as the 'malloc()' just above, shouldn't it ?Signed-off-by: Christophe Jaillet

With commit 3f1b0e1f287547903f11fa1e6de7d2765597766e ".gitignore update"
Linus's current git tree starts to ignore any "*.rej" files.
So "git status" no longer shows these files, but the ones who works with
quilt patchsets, this not makes life easier as expected.
Because sometimes a work flow (at least for me) requires
"quilt push -f" followed by "git status" to see unresolved merge
conflicts, work on these conflicts to correct them and finalize
the patch with "quilt refresh".And if there are some "*.rej" files exists in tree, for whatever
reason, this means something goes really wrong there and i think
this situation not deserves to be ignored.Signed-off-by: S.Çağlar Onur

Disable modpost warnings for linkonce sections
My build gives lots of warnings like
WARNING: sound/core/snd.o (.gnu.linkonce.wi.mpspec_def.h.30779716): unexpected section name.
The (.[number]+) following section name are ld generated and not expected.
Did you forget to use "ax"/"aw" in a .S file?
Note that for example contains
section definitions for use in .S files.But for .linkonce. duplicated sections are actually ok and expected.
So just disable the warning for this case.Signed-off-by: Andi Kleen

Alexey Dobriyan introduced a code adds
menuconfig SOMETHING in Kconfig to tags output when you did "make tags".See http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=80ff26241623875636674a31c0540a78c0fb5433
"make tags" may work fine with his code. However make TAGS doesn't work well
because etags command requires backslashes to escape meta characters like
`(', `)' and `|'.Here is a patch.

The generic semaphore rewrite had a huge performance regression on AIM7
(and potentially other BKL-heavy benchmarks) because the generic
semaphores had been rewritten to be simple to understand and fair. The
latter, in particular, turns a semaphore-based BKL implementation into a
mess of scheduling.The attempt to fix the performance regression failed miserably (see the
previous commit 00b41ec2611dc98f87f30753ee00a53db648d662 'Revert
"semaphore: fix"'), and so for now the simple and sane approach is to
instead just go back to the old spinlock-based BKL implementation that
never had any issues like this.This patch also has the advantage of being reported to fix the
regression completely according to Yanmin Zhang, unlike the semaphore
hack which still left a couple percentage point regression.As a spinlock, the BKL obviously has the potential to be a latency
issue, but it's not really any different from any other spinlock in that
respect. We do want to get rid of the BKL asap, but that has been the
plan for several years.These days, the biggest users are in the tty layer (open/release in
particular) and Alan holds out some hope:"tty release is probably a few months away from getting cured - I'm
afraid it will almost certainly be the very last user of the BKL in
tty to get fixed as it depends on everything else being sanely locked."so while we're not there yet, we do have a plan of action.

This reverts commit bf726eab3711cf192405d21688a4b21e07b6188a, as it has
been reported to cause a regression with processes stuck in __down(),
apparently because some missing wakeup.Quoth Sven Wegener:
"I'm currently investigating a regression that has showed up with my
last git pull yesterday. Bisecting the commits showed bf726e
"semaphore: fix" to be the culprit, reverting it fixed the issue.Symptoms: During heavy filesystem usage (e.g. a kernel compile) I get
several compiler processes in uninterruptible sleep, blocking all i/o
on the filesystem. System is an Intel Core 2 Quad running a 64bit
kernel and userspace. Filesystem is xfs on top of lvm. See below for
the output of sysrq-w."See
http://lkml.org/lkml/2008/5/10/45
for full report.
In the meantime, we can just fix the BKL performance regression by
reverting back to the good old BKL spinlock implementation instead,
since any sleeping lock will generally perform badly, especially if it
tries to be fair.Reported-by: Sven Wegener

It actually makes much more sense there, and we do tend to need it for

System topology on intel based system needs to be exported
for non-numa case as well.All parts of asm-i386/topology.h has come under
#ifdef CONFIG_NUMA after the merge to asm-x86/topology.h/sys/devices/system/cpu/cpu?/topology/* is populated based on
ENABLE_TOPO_DEFINESThe sysfs cpu topology is not being populated on my dual socket
dual core xeon 5160 processor based (x86 32 bit) system.CONFIG_NUMA is not set in my case yet the topology is relevant
and useful.irqbalance daemon application depends on topology to build the
cpus and package list and it fails on Fedora9 beta since the
sysfs topology was not being populated in the 2.6.25 kernel.I am not sure if it was intentional to not define ENABLE_TOPO_DEFINES
for non-numa systems.This fix has been tested on the above mentioned dual core, dual socket

709f744 causes my computer to freeze during the start up of X and my
login manger (GDM). It gets to the point where it has shown the default
X mouse cursor logo (a big X / cross) and does not respond to anything
from that point on.This worked fine before 709f744, and it works fine with 709f744
reverted on top of Linus' current tree (f74d505). The revert had
conflicts, as far as I can tell due to white space changes. The diff I

On some of our (single board computer) boards (x86) we are using an
IPMI controller that uses I/O ports 0x62 and 0x66 for a KCS (keyboard
controller style) IPMI system interface.Trying to load the openipmi driver fails, because the ports
(0x62/0x66) are reserved for keyboard. keyboard reserves the full
range 0x60-0x6F while it doesn't need to.Reserve only ports 0x60 and 0x64 for the legacy PS/2 i8042 keyboad
controller instead of 0x60-0x6F to allow the openipmi driver to work.[ tglx: added 64bit fixup ]

A lot of stuff in spitz/akita/etc. depends on corgi_ssp to be initialised
early. However corgi_ssp initialisation fails, because at that time pxa*-ssp
devices don't have drivers. Move ssp earlier in the makefile so they are
registered before corgi-ssp.Also move sleep/suspend and cpu-freq to more logical places

Linus found a logic bug: we ignore the version number in a module's
vermagic string if we have CONFIG_MODVERSIONS set, but modversions
also lets through a module with no __versions section for modprobe
--force (with tainting, but still).We should only ignore the start of the vermagic string if the module
actually *has* crcs to check. Rather than (say) having an
entertaining hissy fit and creating a config option to work around the
buggy code.Signed-off-by: Rusty Russell
Signed-off-by: Linus Torvalds -
We allow missing __versions sections, because modprobe --force strips
it. It makes less sense to allow sections where there's no version
for a specific symbol the module uses, so disallow that.Signed-off-by: Rusty Russell
Signed-off-by: Linus Torvalds -
Don't allow a module built without versions altogether to be inserted
into a kernel which expects modversions.modprobe --force will strip vermagic as well as modversions, so it
won't be effected, but this will make sure that a
non-CONFIG_MODVERSIONS module won't be accidentally inserted into a
CONFIG_MODVERSIONS kernel.Signed-off-by: Rusty Russell
