This patch adds the PCMCIA client driver for the AVM A1/Fritz!PCMCIA
ISDN cards, which has been in 2.4 for some time already.

Damn it, use the normal "-p1" format for patches!

  The following patch addresses a name change (i_zombie --> i_sem) within
struct inode, which affects fs/intermezzo/vfs.c.

   The following patch fixes a compile error regarding a name change
within task_struct, which affects ISLENTO().

It looks like there are no in-tree users of path_init.
Maybe it can be removed.

another resend of the partition patch for ibm.c. Nobody sent a veto so far
so please add it.

seems someone else was faster fixing the hardsects problem in the xpram
driver.  We continued with my new version of the xpram driver.  Arnd
Bergmann found some bugs and added support for the driverfs.

The dasd driver as a module needs to call elevator_init/elavator_exit to
change the elevator algorithm to elevator_noop.

1) Replace is_read_only with bdev_read_only. The last user of is_read_only
   is gone...
2) Remove alloc & free of the label array in dasd_genhd. This is needed for
   the label array extension but this is a patch of its own.
3) Maintain the old behaviour of /proc/dasd/devices. Its is possible again
   to use "add <devno>" instead of "add device <devno>" or "add range=<devno>".

1) Add __s390__ to the list of architectures that use unsigned int as
   type for rautofs_wqt_t. __s390__ is defined for both 31-bit and 64-bit
   linux for s/390. Both architectures are fine with unsigned int since
   sizeof(unsigned int) == sizeof(unsigned long) for 31 bit s/390.
2) Remove early initialization call ccwcache_init(). It doesn't exists
   anymore.
3) Remove special case for irq_stat. We moved the irq_stat structure out
   of the lowcore.
4) Replace acquire_console_sem with down_trylock & return to avoid an
   endless trap loop if console_unblank is called from interrupt context
   and the console semaphore is taken.

some recent changes in the s390 architectures files:
1) Makefile fixes.
2) Add missing include statements.
3) Convert all parametes in the 31 bit emulation wrapper of sys_futex.
4) Remove semicolons after 'fi' in Config.in
5) Fix scheduler defines in system.h
6) Simplifications in qdio.c

Pure luck that this ever worked at all. The optimized assembly for XOR
in RAID-5 declared did clobber registers, but did declare them as read-only.
I'm pretty sure that at least the 4 disk and possibly the 5 disk cases
did corrupt callee saved registers. The others probably got away because
they were always used in own functions (and only clobbering caller saved
registers)and only called via pointers, preventing inlining.

Some of the replacements are a bit complicated because the functions
exceed gcc's 10 asm argument limit when each input/output register needs
two arguments. Works around that by saving/restoring some of the registers
manually.

I wasn't able to test it in real-life because I don't have a RAID
setup and the RAID code didn't compile since several 2.5 releases.
I wrote some test programs that did test the XOR and they showed
no regression.

Also aligns to XMM save area to 16 bytes to save a few cycles.

This renames 'xqm.h' to a bit better (more consistent with rest of
sources) name.

Patch to reorder the APIC configuration so that dependencies are
determined beforehand for MCE. Keith Owens pointed this out a whiles back
actually.

It seems func.h needs to inlude linux/kdev_t.h:

For some odd reason, the blkdev.h changes did not get patched into your
tree from the patch I sent?! Anyways, here's that change:

This patch fixes the following problems in the file lease:
	when there are multiple shared leases on a file, all the
		lease holders get notified when someone opens the
		file for writing (used to be only the first).
	when a nonblocking open breaks a lease, it will time out
		as it should (used to never time out).

This should make the leases code more usable (hopefully).

This patch makes copy_siginfo_to_user excplicitly copy the correct
union member.  Previously we were getting the correct result but
really by accident.

I needed these to make 2.5.22 build for me.

arch/ppc64/kernel/sys_ppc32.c has a getname32 function.  The only
difference between it and getname() is that it calls do_getname32()
instead of do_getname() (see fs/namei.c).  The difference between
do_getname and do_getname32 is that the former checks to make sure that
the pointer it is passed is less that TASK_SIZE and restricts the length
copied to the lesser of PATH_MAX and (TASK_SIZE - pointer).
do_getname32 uses PAGE_SIZE instead of PATH_MAX.

Anton Blanchard says it is OK to remove getname32.

arch/ia64/ia32/sys_ia32.c defined a getname32(), but nothing used it.

This patch removes both.

  without making sure that the target CPU is allowed.

  the current implementation does the following to 'give up' the CPU:

   - it decreases its priority by 1 until it reaches the lowest level
   - it queues the task to the end of the priority queue

  this scheme works fine in most cases, but if sched_yield()-active tasks
  are mixed with CPU-using processes then it's quite likely that the
  CPU-using process is in the expired array. In that case the yield()-ing
  process only requeues itself in the active array - a true context-switch
  to the expired process will only occur once the timeslice of the
  yield()-ing process has expired: in ~150 msecs. This leads to the
  yield()-ing and CPU-using process to use up rougly the same amount of
  CPU-time, which is arguably deficient.

  i've fixed this problem by extending sched_yield() the following way:

  +        * There are three levels of how a yielding task will give up
  +        * the current CPU:
  +        *
  +        *  #1 - it decreases its priority by one. This priority loss is
  +        *       temporary, it's recovered once the current timeslice
  +        *       expires.
  +        *
  +        *  #2 - once it has reached the lowest priority level,
  +        *       it will give up timeslices one by one. (We do not
  +        *       want to give them up all at once, it's gradual,
  +        *       to protect the casual yield()er.)
  +        *
  +        *  #3 - once all timeslices are gone we put the process into
  +        *       the expired array.
  +        *
  +        *  (special rule: RT tasks do not lose any priority, they just
  +        *  roundrobin on their current priority level.)
  +        */

This patch (against 2.5.22) removes the BKL from around the call
to i_op->permission() in fs/namei.c, and pushes the BKL into those
filesystems that have permission() methods that require it.

This contains the following changes to the SCSI tape driver:

- one buffer is used for each tape (no buffer pool)
- buffers allocated when needed and freed when device closed
- common code from read and write moved to a function
- default maximum number of scatter/gather segments increased to 64
- tape status set to "no tape" after succesful unload

Nobody's using it any more, kill:
