snd_seq_kernel_client_ctl() - I should've guessed from the name alone
;-)

Annotated sound/drivers/opl*

The tricky part here was an iterator that used to take a callback and
argument for that callback as parameters.  Iterator itself didn't care
what type that argument had been; it's entirely up to callback.  The
thing is, two callbacks expect (and get) char __user * while other two
expect (and also get) char __user **.

Iterator used to use void * as "opaque data"; I've switched it to
unsigned long.  Note that there was nothing that said "it's a pointer" -
use of callback that would take e.g.  int is also perfectly legitimate. 

The rest is triviali annotation.

Annotated method prototypes, commonly used ioctl-only structures and

copy_from_user() where copy_to_user() should've been.  Unfortunately, on
x86 they are almost identical, so it went unnoticed for quite a while.

msnd_pinnacle/msnd_classic do copy_{to,from}_user under a spinlock.

Taken out of spinlock (into a temp. buffer). Calls of msnd_fifo_{read,write}
always go from kernel buffer now, so we can drop the 'int user' argument in
them _and_ simplify error handling - all errors were from copy_..._user() and
now these are called directly by dsp_read()/dsp_write().

	In some cases snd_sb_csp_load() did kmalloc() and copy_from_user()
under a spinlock.  Split into snd_sb_csp_load() and snd_sb_csp_load_user() -
ther former always from kernel pointer, the latter - from userland.
	snd_sb_csp_load_user() doesn't take any locks itself, it just
does kmalloc, copy_from_user and calls snd_sb_csp_load() to do the rest.

Patch from Nicolas Pitre

Don't include them from hardware.h

Since asm/arch/hardware.h is included (indirectly) by most kernel
files, we don't want all these files depending on the individual
machine support files, especially as only five files really require
the header.

Instead, explicitly include lubbock.h into files as necessary.

Patch from Tony Lindgren

Update the IO register names in entry-armv.S

When I moved the exports into arch/ppc/lib/locks.c, I forgot to
include module.h, so it doesn't compile (with CONFIG_SMP +
CONFIG_SPINLOCK_DEBUG).  This patch fixes it.

The last patch I sent means that we have WARN_ON(0) in a couple of

Ben H added a check in a couple of places to make sure that we had

Unfortunately the check he used trips in the case when

macro (which reduces to 0 when CONFIG_PREEMPT=n) and doing
WARN_ON(preemptible()).

The main thrust of this patch is to make the ppc32 PCI code more
robust by checking for bus->resource[] being NULL before using it.  We
can legitimately get elements of bus->resource being NULL and I have
actually hit that on some machines.  This patch also allows resources
starting at 0 to be accepted as assigned (we can and do get PCI
resources starting at 0 in I/O space on PPC machines) and provides a
sensible default for the case where Open Firmware doesn't give us a
bus-range property for a PCI bridge.

The ppc32 boot code has a couple of files that are executed very early
on before the kernel is mapped at the address it is linked at.  We
have been using -mrelocatable-lib to compile these files, but
apparently -mrelocatable-lib is deprecated and the gcc developers are
threatening to remove it.  In fact the -fPIC flag does what we need.
This patch changes -mrelocatable-lib to -fPIC.

In the ppc32 kernel, we have a /proc/ppc_htab file that trawls through
the MMU hash table and prints various statistics on it such as percent
occupancy.  However, the hash table entry format is different on
64-bit cpus (POWER3, G5) which the ppc32 kernel does support (in
32-bit mode).

This patch disables the scanning of the MMU hash table and printing of
the statistics that we get from it on 64-bit cpus.  Since the
statistics are only for interest, and the ppc32 kernel is being used
less and less on 64-bit cpus now that the ppc64 kernel is in
reasonable shape, I didn't think it worth while to add code to deal
with the 64-bit HPTE format.

This patch is the ppc32 counterpart to a fix that went into

I tried compiling a PPC32 kernel with PREEMPT + SMP and it failed
because we didn't have a _raw_write_trylock.  This patch adds
_raw_write_trylock, moves the exports of _raw_*lock from
arch/ppc/kernel/ppc_ksyms.c to arch/ppc/lib/locks.c, and makes
__spin_trylock static since it is only used in locks.c.

clean_blockdev_aliases() is using the wrong thing to work out how many
filesystem blocks should be invalidated.  It invalidates too many, which can
cause live fs metadata buffers to be invalidated when they are pending
writeout.  It's a filesystem-wrecker, although seems very hard to hit.

Chris Mason and I ran across this one while hunting down another bug.

If ext3_mark_iloc_dirty() fails in ext3_orphan_del() on the outer buffer,
bh->b_count will be decremented twice.  ext3_mark_iloc_dirty() will brelse
the buffer, even on error.  ext3_orphan_del() is explicity brelse'ing the
buffer on error.  Prior to calling ext3_mark_iloc_dirty(), this is the
correct behavior.
