Only in 2.4.12aa1: 00_backout-2.4.11pre1-1
Only in 2.4.12aa1: 00_o_direct-2
Only in 2.4.13pre2aa1: 00_o_direct-3

Made a self contained patch that applies cleanly to 2.4.13pre2 ready
for merging. Many thanks to Janet Morgan for fiding another bug in the
blkdev O_DIRECT support.

Only in 2.4.12aa1: 00_cache-without-buffers-1
Only in 2.4.12aa1: 00_parport-fix-1

Just in mainline.

Only in 2.4.13pre2aa1: 00_files_struct_rcu-2.4.10-04-1

File locking read/write spinlock replaced with RCU.

Only in 2.4.13pre2aa1: 00_ordered-freeing-1

Free the pages so that they gets allocated in physical order later,
shouldn't matter but I got reports of slower in-core (cache)
performance on some arch after a fresh boot, and speedup after the
freelist got randomized by load.

Only in 2.4.13pre2aa1: 00_rcu-poll-1

RCU implementation based on latest Dipankar's patch against 2.4.10.
I changed it so that it only has as fast-path/reader-load cost a
per-cpu counter increment in scheduler and nothing else. It is not
arch dependent either. I also tried to optimized the UP case.

Only in 2.4.12aa1: 00_rwsem-fair-22
Only in 2.4.13pre2aa1: 00_rwsem-fair-23

Rediffed.

Only in 2.4.12aa1: 00_rwsem-fair-22-recursive-4
Only in 2.4.13pre2aa1: 00_rwsem-fair-23-recursive-4

Renamed.

Only in 2.4.12aa1: 00_vm-2
Only in 2.4.13pre2aa1: 00_vm-3
Only in 2.4.13pre2aa1: 00_vm-3.1

Further vm changes, backed out the PG_wait_for_IO since it seems not
to make a relevant difference. Should behave better under swap load.
In particular I'm probing the inactive list from shrink_cache now,
so that I get feedback on when it's time to swap before the shrinks
on the inactive list starts failing.

Only in 2.4.12aa1: 10_compiler.h-1
