Another step in the effort to eliminate the SN pda structure.
This patch moves the cnodeid_to_nasid_table field out of the pda,
making it a standalone per-cpu data item, and exports it so it can
be accessed by kernel modules.

This is a small patch to switch fluch_icache_range() to use fc.i
instead of fc. This would save time on processors which can establish
i-cache coherency without flushing the cache-line out to memory (not
that any current processors do). On existing processors, fc.i behaves
like fc. The only caveat is that very old assemblers may not know
about fc.i yet.

gcc-4.0 generates altivec code implicitly when -mcpu indicates an
altivec capable CPU which is not suitable for the kernel. However, we
used to set -mcpu=970 when CONFIG_ALTIVEC was set because a gcc-3.x bug
prevented from using -maltivec along with -mcpu=power4, thus prevented
building the RAID6 altivec code.
This patch fixes all of this by testing for the gcc version. If 4.0 or
later, just normally use -mcpu=power4 and let the RAID6 code add
-maltivec to the few files it needs to be compiled with altivec support.
For 3.x, we still use -mcpu=970 to work around the above problem, which
is fine as 3.x will never implicitly generate altivec code.
The Makefile hackery may not be the most lovely, I welcome anybody more
skilled than me to improve it.

When adding more formatted audit data to an skb for delivery to userspace,
the kernel will attempt to reuse an skb that has spare room. However, if
the audit message has already been fragmented to multiple skb's, the search
for spare room in the skb uses the head of the list. This will corrupt the
audit message with trailing bytes being placed midway through the stream.
Fix is to look at the end of the list.

This patch adds jfs_syncpt, which calls lmLogSync to write sync points
to the journal both in jfs_sync_fs and when sync barrier processing
completes.
lmLogSync accomplishes two things: 1) it pushes logged-but-dirty

so that jfs_fsck doesn't need to replay more transactions than is
necessary.

JFS was creating a new IAG (inode aggregate group) in one address
space, and afterwards, accessing it from another. This could lead to
complications when cache pages contain more than one page of jfs

address space that it is subsequently accessed with.
This also elimitates an I/O, but IAG's aren't created too often.

I have recompiled Linux kernel 2.6.11.5 documentation for me and our
university students again. The documentation could be extended for more
sources which are equipped by structured comments for recent 2.6 kernels. I
have tried to proceed with that task. I have done that more times from 2.6.0
time and it gets boring to do same changes again and again. Linux kernel
compiles after changes for i386 and ARM targets. I have added references to
some more files into kernel-api book, I have added some section names as well.
So please, check that changes do not break something and that categories are
not too much skewed.
I have changed kernel-doc to accept "fastcall" and "asmlinkage" words reserved
by kernel convention. Most of the other changes are modifications in the
comments to make kernel-doc happy, accept some parameters description and do
not bail out on errors. Changed <pid> to @pid in the description, moved some
#ifdef before comments to correct function to comments bindings, etc.
You can see result of the modified documentation build at
http://cmp.felk.cvut.cz/~pisa/linux/lkdb-2.6.11.tar.gz
Some more sources are ready to be included into kernel-doc generated
documentation. Sources has been added into kernel-api for now. Some more
section names added and probably some more chaos introduced as result of quick
cleanup work.
