Fix kernel-doc notation in linux/mutex.h and kernel/mutex.c,
then add these 2 files to the kernel-locking docbook as the
Mutex API reference chapter.
Add one API function to mutex-design.txt and correct a typo in
that file.

Chapter 6 is right about mutex_trylock, but chapter 10 wasn't. This error
was introduced during semaphore-to-mutex conversion of the Unreliable
guide. :-)
If user context which performs mutex_lock() or mutex_trylock() is
preempted by interrupt context which performs mutex_trylock() on the same
mutex instance, a deadlock occurs. This is because these functions do not
disable local IRQs when they operate on mutex->wait_lock.

Since the consensus seems to be to eliminate semaphores where possible,
we shouldn't be educating people about how to use them as locks. Use
mutexes instead. Semaphores should be described in a separate document
if we end up keeping them.

I converted some of the document to reflect mutex usage instead of
semaphore usage. Since we shouldin't be promoting semaphore usage when
it's on it's way out..

Andi Kleen pointed out to me that the kernel locking cheat sheet
table entries are unreadable.
Make table entries smaller so that pdf and ps output is readable
(columns were being overwritten and garbled) by using abbreviations.
This allows the tables to fit on one page cleanly.
Add a Legend for the abbreviations:
SLIS: spin_lock_irqsave
SLI: spin_lock_irq
SL: spin_lock
SLBH: spin_lock_bh
DI: down_interruptible

doc patch: Consistently use quotes for SGML attributes This makes it

As of 2.6.3, restore_flags will no longer modify cwp on sparc.
Therefore you can apply this patch to the locking guide.
[ Indeed. I'll also remove the atomic comments from Hacking
Guide as part of my revision there when I get back to it. --RR ]

The new-and-improved kernel-locking kerneldoc seems to be missing some end
tags which causes 'make foodocs' to die. I'm not sure if it's because of
my not-bleeding-edge docbook utils or if it's a genuine error. Since most
ending tags are present I tend to think it's an error.

Entirely revised, and largely rewritten. Has a continuing example now, which
I think makes things clearer. Also covers Read Copy Update. This version
further deprecates rwlock_t, shuffles sections for better organization.

From: Christoph Hellwig <hch@lst.de>
Still three arches keep an unused copy around and quite a few places refer
to it in comments still.
Two of the two arches also include it in their _ksyms.c file, but given
that softirq.h only contains macros (which are in hardirq.c as well) that's
just a leftover as well.

timer_exit() isn't a public function, and doesn't even exist in 2.5.
2.4 calls it internally after timers. It seems timer users need not
do anything special.

atomic ops are *not* barriers any more.
