x86: correct register constraints for 64-bit atomic operations

2008-08-18T05:47:30+00:00

x86_64 add/sub atomic ops does not seems to accept integer values bigger
than 32 bits as immediates. Intel's add/sub documentation specifies they
have to be passed as registers.

The only operations in the x86-64 architecture which accept arbitrary
64-bit immediates is "movq" to any register; similarly, the only
operation which accept arbitrary 64-bit displacement is "movabs" to or
from al/ax/eax/rax.

http://gcc.gnu.org/onlinedocs/gcc-4.3.0/gcc/Machine-Constraints.html

states :

e
    32-bit signed integer constant, or a symbolic reference known to fit
    that range (for immediate operands in sign-extending x86-64
    instructions).
Z
    32-bit unsigned integer constant, or a symbolic reference known to
    fit that range (for immediate operands in zero-extending x86-64
    instructions).

Since add/sub does sign extension, using the "e" constraint seems appropriate.

It applies to 2.6.27-rc, 2.6.26, 2.6.25...

x86: consolidate header guards

2008-07-22T19:31:34+00:00

This patch is the result of an automatic script that consolidates the
format of all the headers in include/asm-x86/.

The format:

1. No leading underscore. Names with leading underscores are reserved.
2. Pathname components are separated by two underscores. So we can
   distinguish between mm_types.h and mm/types.h.
3. Everything except letters and numbers are turned into single
   underscores.

x86: Remove obsolete LOCK macro from include/asm-x86/atomic_64.h

2008-05-25T20:42:25+00:00

Commit d167a518 "[PATCH] x86_64: x86_64 version of the smp alternative patch."
has left the LOCK macro in include/asm-x86_64/atomic.h, which is now
include/asm-x86/atomic_64.h. Its scope should be local to the file, other
architectures don't provide it, I couldn't find an in-tree user of it and
allyesconfig, allmodconfig and allnoconfig build fine without it, so this patch
removes it.

x86: make atomic64_t work like atomic_t

2007-10-17T18:16:21+00:00

The volatile keyword has already been removed from the declaration of atomic_t
on x86_64.  For consistency, remove it from atomic64_t as well.
