Differences with `Kernelver':

o inode leakage fix (syncing back dirty inode when there's noting
of freeable in the inode-inuse list.

o fixed kpiod (PF_MEMALLOC) and improved

o complete /proc race fixes

o my latest VM with nr_freeable_pages balance. It should work very
well on low memory and the system should run smoothly also under
intensive swap operations.

o improved tqueue.h (better scale in SMP and removed a cli())

o My new update_shared_mappings() code. This will greatly improve
performance while handling shared mmaped files from different contexts.

o irq_state array is PII cache aligned (32byte to decrease bus traffic
under intense irq activities in SMP)

o dynamic buffer hash table size (big improvement for high memory
machines, and saved memory for low memory machines)

o final fix for the disable/enable_bh I fixed some weeks ago
This patch fix also a possible not critical race in remove_bh(),
btw note the wmb() to take care of SMP ;).

o latest IEEE1284 parport code from Tim Waugh.

o get_wchan() moved in arch specific section and CTRL+SCROLL-LOCK
use get_wchan() to get the PC filed information.

o fixed page bound limits and the case of a new forked not
scheduled yet process in get_wchan()

o some still pending (not yet merged from Alan) jiffies wrap update

o reimplemented hopefully completly wrap compliant time
to jiffies/msec (and reverse) functions

o little vmalloc fix + vmalloc SMP thread safety

o bttv doesn't generate 50 irq per sec even if not used

o some other thing
