of a PVR support patch.

restoring the CTR value after an AUX write by default, which
breaks Transmeta Crusoe i8042 chip emulation. The option might
be needed on some ancient hardware, though.
Move registration of the KBD interface after the AUX probe. This
makes sure we don't kill the keyboard by probing for the AUX port.
Fix a bug in i8042.c which only enables the interfaces after the
probe routine for mice/keyboards was executed.
Add some paranoia flush/sync calls to make sure the chip doesn't get
stuck.
Don't check_region, we already request_region where applicable.
Do i8042_reset on all non-PC architectures.
Cleanup comments.
Add an i8042_restore_ctr command line option. This allows not

struct by a single struct to simplify passing it around and to

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.

make cpqarray and cciss use these

Heading Rusty off at the pass...

This also changes and array initialiser...

get_spare recently became static and no-one told md_k.h

Sync_sbs tries to access the ->sb for the first rdev of an mddev.
This can oops as the wrong arg is given to list_entry, and also
if a define was faound to be failed, as failed devices have their ->sb
removed.  But that removal isn't necessary, so now an rdev will always
have an ->sb.

Define container_of which cast from member to struct with some type checking.

This is much like list_entry but is cearly for things other than lists.

List_entry now uses container_of.

Dawson Engler's Stanford Checker reported this missing unlock to
LKML 11 July (amongst "56 potential lock/unlock bugs in 2.5.8").

Found by Simon Trimmer <simon@veritas.com>: shmem_file_write
failure path duplicates kunmap, causing oops holding kmap_lock.

Trivial: vfs_link in 2.5 checks S_ISDIR first, shmem_link
need not repeat it, but test crept back in at some stage.

Martin Schwidefsky <schwidefsky@de.ibm.com> reported "Bug with shared
memory" to LKML 14 May: hang due to schedule in truncate_list_pages
called from .... shm_destroy holding shm_lock spinlock.  shm_destroy
needs that lock for shm_rmid, but it can be safely unlocked once link
from id to shp has been removed.

Here is a quick fix.  I would like to synchronize with the irq handler
changes as well.  Becouse right now I know that preemption is killing
the disk subsystem when moving data between disks using different
request queues...  In esp.  It get's me in to do_request() with a queue
in unplugged state.  (Not everything is my fault, after all :-).

 - init thread needs to have preempt_count of 1 until sched_init().
   (William Lee Irwin III)
 - clean up the irq-mask macros. (Linus)
 - add barrier() to irq_enter() and irq_exit(). (based on Oleg Nesterov's
   comment.)
 - move the irqs-off check into preempt_schedule() and remove
   CONFIG_DEBUG_IRQ_SCHEDULE.
 - remove spin_unlock_no_resched() and comment the affected places more
   agressively.
 - slab.c needs to spin_unlock_no_resched(), instead of spin_unlock(). (It
   also has to check for preemption in the right spot.) This should fix
   the memory corruption.
 - irq_exit() needs to run softirqs if interrupts not active - in the
   previous patch it ran them when preempt_count() was 0, which is
   incorrect.
 - spinlock macros are updated to enable preemption after enabling
   interrupts. Besides avoiding false positive warnings, this also
 - fork.c has to call scheduler_tick() with preemption disabled -
   otherwise scheduler_tick()'s spin_unlock can preempt!
 - irqs_disabled() macro introduced.
 - [ all other local_irq_enable() or sti instances conditional on
     CONFIG_DEBUG_IRQ_SCHEDULE are to fix false positive warnings. ]
 - fix buggy in_softirq(). Fortunately the bug made the test broader,
   which didnt result in algorithmical breakage, just suboptimal
   performance.
 - move do_softirq() processing into irq_exit() => this also fixes the
   softirq processing bugs present in apic.c IRQ handlers that did not
   test for softirqs after irq_exit().
 - simplify local_bh_enable().

Amiga Zorro bus updates
 - Bring APUS Zorro bus announcement in sync with the m68k version
 - Fix typo in Zorro device generator name
 - Kill duplicate ] in Zorro device ID database
 - Include <asm/io.h> instead of duplicating definitions from <asm/io.h>

console.wait_key was removed

M68k VT updates:
  - Include <linux/vt_kern.h> instead of copying the kd_mksound() prototype
  - Lots of stuff depends on CONFIG_VT:
      o SYSRQ_KEY
      o kd_mksound()
      o mach_keyb_init()
      o mach_kbdrate()
      o mach_kbd_leds()
      o mach_kbd_translate()
      o mach_sysrq_xlate()
      o Atari keyboard and joystick drivers
  - There's no need to provide dummy routines for kbd{rate,_leds}()
  - dummy_con depends on CONFIG_DUMMY_CONSOLE
