linux-toradex.git/include/asm-sh/atomic.h, branch v2.6.24.2

sh: Split out atomic ops logically.

2006-12-11T23:42:08+00:00

We have a few different ways to do the atomic operations, so split
them out in to different headers rather than bloating atomic.h.
Kernelspace gUSA will take this up to a third implementation.

sh: Fixup movli.l/movco.l atomic ops for gcc4.

2006-12-06T01:45:40+00:00

gcc4 gets a bit pissy about the outputs:

include/asm/atomic.h: In function 'atomic_add':
include/asm/atomic.h:37: error: invalid lvalue in asm statement
include/asm/atomic.h:30: error: invalid lvalue in asm output 1
...

this ended up being a thinko anyways, so just fix it up.

Verified for proper behaviour with the older toolchains, too.

sh: New atomic ops for SH-4A movli.l/movco.l

2006-09-27T08:52:19+00:00

SH-4A implements LL/SC instructions, so we implement a simple
set of atomic operations using these.

sh: Various cosmetic cleanups.

2006-09-27T03:31:01+00:00

We had quite a bit of whitespace damage, clean most of it up..

[PATCH] atomic_long_t & include/asm-generic/atomic.h V2

2006-01-06T16:33:29+00:00

Several counters already have the need to use 64 atomic variables on 64 bit
platforms (see mm_counter_t in sched.h).  We have to do ugly ifdefs to fall
back to 32 bit atomic on 32 bit platforms.

The VM statistics patch that I am working on will also make more extensive
use of atomic64.

This patch introduces a new type atomic_long_t by providing definitions in
asm-generic/atomic.h that works similar to the c "long" type.  Its 32 bits
on 32 bit platforms and 64 bits on 64 bit platforms.

Also cleans up the determination of the mm_counter_t in sched.h.

[PATCH] atomic: inc_not_zero

2005-11-14T02:14:16+00:00

Introduce an atomic_inc_not_zero operation.  Make this a special case of
atomic_add_unless because lockless pagecache actually wants
atomic_inc_not_negativeone due to its offset refcount.

Linux-2.6.12-rc2

2005-04-16T22:20:36+00:00

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.

Let it rip!
