Update for removed global irq lock

Rediffed with the 2.5.28 biosparm change included

irq can be -1 if the card errors during config. synchronize_irq(-1) looks
bad

The Q40 keyboard is only found on a Q40..

Event is just used for internal flags and with set_bit for atomicity. This
kills the warning the obvious way

Whoever updated it was coding without due care and attention 8)

Inexplicably, xor.c enabled interrupts...

Here it is my first LK patch.
tested even. :)

the global irq-lock debugging

cpqfcTSinit.c:
  Fix usage of Scsi_Cmnd->request so it will compile.

 - introduce new type of context-switch locking, this is a must-have for
   ia64 and sparc64.

 - load_balance() bug noticed by Scott Rhine and myself: scan the
   whole list to find imbalance number of tasks, not just the tail
   of the list.

 - sched_yield() fix: use current->array not rq->active.

Switch to set_current_state() and move before add_wait_queue().
Updated README from master HTML file.
Fixed devfs entry leak in <devfs_readdir> when *readdir fails.

The patch below consolidates some duplicate code, reduces some
indentation, and adds a freeing of a page in mem_read() that could be left
unfreed, as far as I can see.
