Paul Mundt	8c0b8139c8	sh: consolidate atomic_cmpxchg()/atomic_add_unless() definitions. The LL/SC and IRQ versions were using generic stubs while the GRB version was just reimplementing what it already had for the standard cmpxchg() code. As we have optimized cmpxchg() implementations that are decoupled from the atomic code, simply falling back on the generic wrapper does the right thing. With this in place the GRB case is unaffected while the LL/SC case gets to use its optimized cmpxchg(). Signed-off-by: Paul Mundt <lethal@linux-sh.org>	2010-01-08 17:02:17 +09:00

sh: consolidate atomic_cmpxchg()/atomic_add_unless() definitions.

The LL/SC and IRQ versions were using generic stubs while the GRB version
was just reimplementing what it already had for the standard cmpxchg()
code. As we have optimized cmpxchg() implementations that are decoupled
from the atomic code, simply falling back on the generic wrapper does the
right thing. With this in place the GRB case is unaffected while the
LL/SC case gets to use its optimized cmpxchg().

This fixes up a typo in the ll/sc based cmpxchg code which apparently
wasn't getting a lot of testing due to the swapped old/new pair. With
that fixed up, the ll/sc code also starts using it and provides its own
atomic_add_unless().

This follows the sparc changes a439fe51a1.
