changelog diff between 2.4.21rc2aa1 and 2.4.21rc4aa1:

Only in 2.4.21rc2aa1: 00_F_DUPFD-fcntl-rlimit-1

Obsoleted by an old patch from Rusty in mainline
(was harmless, just a duplicated check, noticed by
Al Viro)

Only in 2.4.21rc2aa1: 00_extraversion-22
Only in 2.4.21rc4aa1: 00_extraversion-23
Only in 2.4.21rc2aa1: 40_o_direct-reiserfs-1
Only in 2.4.21rc4aa1: 40_o_direct-reiserfs-2

Rediffed.

Only in 2.4.21rc4aa1: 00_fcntl-dupfd-unsigned-long-cleanups-1

Cleanup for the sign issue and removed worthless check.
From Andrew Morton.

Only in 2.4.21rc4aa1: 00_ksoftirqd-max-loop-networking-1

Loop N = 8 times before waking ksoftirqd. That may be
too much but I want to try if still the lots of people complains about
suprious ksoftirqd wakes. Once ksoftirqd is runnable don't loop more
than once (like it's rescheduling, the bulk of the work has to happen
in ksoftirqd still, we can't do more than just one pass if it's running
or we risk very huge unfariness, i.e. like w/o ksoftirqd at all).

Only in 2.4.21rc4aa1: 00_max-threads-pid-nr-1

Don't create more threads than the pid space
on 64bit, from Egenera.

Only in 2.4.21rc2aa1: 00_panic-export-1
Only in 2.4.21rc4aa1: 00_panic-export-2

Merged in mainline (except one last bit).

Only in 2.4.21rc4aa1: 00_profile-read-efault-1

Return -EFAULT if the profile is buffer is invalid,
from Daniele Bellucci.

Only in 2.4.21rc2aa1: 00_remove_inode_page-prune_icache-smp-race-1

Merged in mainline.

Only in 2.4.21rc4aa1: 00_scsi-scan-new-devices-2

Add an hook to trigger a rescan of the scsi devices,
from Egenera.

Only in 2.4.21rc2aa1: 30_irq-balance-13
Only in 2.4.21rc4aa1: 30_irq-balance-14

First assume ksoftirqd running as an idle cpu from irq balancing
purposes. The softirq load statistically follows the hardirq load, so
by going away from ksoftirqd, we may generate a suprious bouncing
across different cpus.

Secondly change irq routing with HT only if the whole physical cpu is
idle.

Only in 2.4.21rc2aa1: 9985_blk-atomic-7
Only in 2.4.21rc4aa1: 9985_blk-atomic-8

The blk-atomic + varyio wasn't right in its first untested version,
the refile had to be a few lines below, this is right and slightly
tested on my 4-way.

Only in 2.4.21rc2aa1: 9995_frlock-gettimeofday-5
Only in 2.4.21rc4aa1: 9995_frlock-gettimeofday-6

Fixed a few missing includes.

Only in 2.4.21rc4aa1: 9999_dm-1

Merge the device mapper (and in turn the mempool and in turn
stop ext3 from abusing the lowlevel b_private).

Only in 2.4.21rc4aa1: 9999_truncate-nopage-race-1

Fix the race between truncate and the page faults
found by Paul Mackerras. the fix uses the sequence
locks (i.e. frlocks since I was too lazy to rename them
in 2.4) to ensure after a truncate none "anonymous" page can be left
mapped. That could generate userspace memory corruption (not kernel
crashes but still potential data loss). Thanks to Daniel McNeil and
Andrew for the help in cleaning up the fix. The design of the fix
allows performance to be unaffected. Crossing fingers that the inode
always exists ;).
