kfree(0) is perfectly valid, checking pointers for NULL before calling 
kfree() on them is redundant. The patch below cleans away a few such 
redundant checks (and while I was around some of those bits I couldn't 
stop myself from making a few tiny whitespace changes as well).

Converts rtm_min and rtm_max arrays to use c99 designated
initializers for easier insertion of new message families.
RTM_GETMULTICAST and RTM_GETANYCAST did not have the minimal
message size specified which means that the netlink message
was parsed for routing attributes starting from the header.
Adds the proper minimal message sizes for these messages
(netlink header + common rtnetlink header) to fix this issue.

RTM_MAX is currently set to the maximum reserverd message type plus one
thus being the cause of two bugs for new types being assigned a) given the
new family registers only the NEW command in its reserved block the array
size for per family entries is calculated one entry short and b) given the
new family registers all commands RTM_MAX would point to the first entry
of the block following this one and the rtnetlink receive path would accept
a message type for a nonexisting family.

This patch changes RTM_MAX to point to the maximum valid message type
by aligning it to the start of the next block and subtracting one.

I made a mistake in my last patch to the raw socket checksum code.
I used the value of inet->cork.length as the length of the payload.
While this works with normal packets, it breaks down when IPsec is
present since the cork length includes the extension header length.

So here is a patch to fix the length calculations.

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.

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
metadata pages to disk, and 2) it writes a sync record to the journal
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
metadata.  This patch causes the IAG to be initialized in the same
address space that it is subsequently accessed with.

This also elimitates an I/O, but IAG's aren't created too often.

The cpufreq core patch I sent earlier got only half-applied.  I added a
flag to let the low level driver disable an annoying warning on
suspend/resume that is normal on ppc, but the "resume" part of it wasn't
applied.

This just adds back that missing bit.  The original patch also reworked
the resume() function to avoid nesting too many if () statements along
the way I did the suspend() one, but I didn't include that in the patch
below.
