ptrace: conditionalize compat_ptrace_request
My recent additions to compat_ptrace_request made it mandatory
for CONFIG_COMPAT arch's to define copy_siginfo_from_user32.
This broke some builds, though they all really should get cleaned
up in that way.
Since all the arch's that actually call compat_ptrace_request have
now been cleaned up to use the generic compat_sys_ptrace, we can
avoid the build problems on the crufty arch's by changing the
conditionals on the definition.

x86_64 vDSO: use initdata
The 64-bit vDSO image is in a special ".vdso" section for no reason
I can determine. Furthermore, the location of the vdso_end symbol
includes some wrongly-calculated padding space in the image, which
is then (correctly) rounded to page size, resulting in an extra page
of zeros in the image mapped in to user processes.
This changes it to put the vdso.so image into normal initdata as we
have always done for the 32-bit vDSO images. The extra padding is
gone, so the user VMA is one page instead of two. The image that
was already copied around at boot time is now in initdata, so we
recover that wasted space after boot.

hrtimer: raise softirq unlocked to avoid circular lock dependency
The scheduler hrtimer bits in 2.6.25 introduced a circular lock
dependency in a rare code path:
=======================================================
[ INFO: possible circular locking dependency detected ]
2.6.25-sched-devel.git-x86-latest.git #19
-------------------------------------------------------
X/2980 is trying to acquire lock:
(&rq->rq_lock_key#2){++..}, at: [<
ffffffff80230146>] task_rq_lock+0x56/0xa0
but task is already holding lock:
(&cpu_base->lock){++..}, at: [<
ffffffff80257ae1>] lock_hrtimer_base+0x31/0x60
which lock already depends on the new lock.
The scenario which leads to this is:
posix-timer signal is delivered
-> posix-timer is rearmed
timer is already expired in hrtimer_enqueue()
-> softirq is raised
To prevent this we need to move the raise of the softirq out of the
base->lock protected code path.

x86: Fix 32-bit MSI-X allocation leakage
This bug was introduced in the 2.6.24 i386/x86_64 tree merge, where
MSI-X vector allocation will eventually fail. The cause is the new
bit array tracking used vectors is not getting cleared properly on
IRQ destruction on the 32-bit APIC code.
This can be seen easily using the ixgbe 10 GbE driver on multi-core
systems by simply loading and unloading the driver a few times.
Depending on the number of available vectors on the host system, the
MSI-X allocation will eventually fail, and the driver will only be
able to use legacy interrupts.
I am generating the same patch for both stable trees for 2.6.24 and
2.6.25.

fat: detect media without partition table correctly
I received a complaint that some FAT formated medias (e.g. sd memory cards)
trigger a "unknown partition table" message even though there is no partition
table and they work correctly, while in general (when e.g. formated with
mkdosfs or even Windows Vista) this message is not shown.
Currently this seems only to happen when the medias get formatted with Windows
XP (and possibly Win 2000). Then the boot indicator byte contains garbage
(part of text message) and so do the other parts checked by msdos_paritition
which then later triggers this message.
References: novell bug #364365
Most fat formatted media without partition table contains zeros in the boot
indication and the other tested bytes and so falls through the checks in
msdos_partition, leading it to return with 1 (all is fine).
But some (e.g. WinXP formatted) fat fomated medias don't use boot_ind and so
the check fails and causes a "unkown partition table" warning eventhough there
is none and everything would be fine.
This additional check directly verifies if there is a fat formatted medium
without a partition table.

fat: Add allow_utime option
Normally utime(2) checks current process is owner of the file, or it
has CAP_FOWNER capability. But FAT filesystem doesn't have uid/gid as
on disk info, so normal check is too unflexible.
With this option you can relax it.

fat: fat_setattr() fix
Fix fat_setattr() on the case of showexec option. If user specified
showexec option, inode->i_mode may not have S_IXUGO. This just use
inode->i_mode to fix it.
And with this patch, we don't allow chmod() on memory inode, it's just
bad behaviour. IOW, we allow changing S_IWUGO only which can be stored
to disk.

reiserfs: unpack tails on quota files
Quota files cannot have tails because quota_write and quota_read functions do
not support them. So far when quota files did have tail, we just refused to
turn quotas on it. Sadly this check has been wrong and so there are now
plenty installations where quota files don't have NOTAIL flag set and so now
after fixing the check, they suddently fail to turn quotas on. Since it's
easy to unpack the tail from kernel, do this from reiserfs_quota_on() which
solves the problem and is generally nicer to users anyway.

reiserfs: fix hang on umount with quotas when journal is aborted
Call dquot_drop() from reiserfs_dquot_drop() even if we fail to start a
transaction. Otherwise we never get to dropping references to quota
structures from the inode and umount will hang indefinitely.
