[XFS] allow enabling CONFIG_XFS_DEBUG
Back when I first submitted XFS for mainline inclusion we made the
decision that the debug code is far to extensive to be accidentally
enabled by users in mainline. But then again it's often quite useful
to track problems down and hacking the makefile all the time is rather
annoying. Given all the debug options with even more overhead like
lockdep or DEBUG_PAGE_ALLOC users (or rather developers) should know
by now what they're doing.

[XFS] Don't initialise new inode generation numbers to zero
When we allocation new inode chunks, we initialise the generation numbers
to zero. This works fine until we delete a chunk and then reallocate it,
resulting in the same inode numbers but with a reset generation count.
This can result in inode/generation pairs of different inodes occurring
relatively close together.
Given that the inode/gen pair makes up the "unique" portion of an NFS
filehandle on XFS, this can result in file handles cached on clients being
seen on the wire from the server but refer to a different file. This
causes .... issues for NFS clients.
Hence we need a unique generation number initialisation for each inode to
prevent reuse of a small portion of the generation number space. Use a
random number to initialise the generation number so we don't need to keep
any new state on disk whilst making the new number difficult to guess from
previous allocations.

ARM: always select HAVE_IDE
It's plain wrong for PCMCIA to select HAVE_IDE that implies e.g. the
availability of an asm/ide.h
It turns out this was done for ARM, and we can simply always select
HAVE_IDE on ARM instead of manually tracking which platforms might
possible have an IDE controller directly or indirectly.

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.

kbuild: show defconfig subdirs in make help
PowerPC will start moving board defconfigs into subarch-specific
subdirs soon. "make help" currently does not look in subdirs to
find the defconfigs to show. This is partially a good thing,
since there are way too many defconfigs for one list.
This patch makes the main "make help" display something like
help-40x - Show 40x-specific targets
help-44x - Show 44x-specific targets
help-boards - Show all of the above
and wires up stuff so those new help-* commands actually work.

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.
