FRV: Don't make smp_{r, w, }mb() interpolate MEMBAR when CONFIG_SMP=n [try #2]

2008-04-10T20:41:29+00:00

Don't make smp_{r,w,}mb() interpolate a MEMBAR instruction when CONFIG_SMP=n as
SMP memory barries on UP systems should interpolate a compiler barrier only.

Fix FRV cmpxchg_local

2008-02-08T23:33:32+00:00

Fix the FRV cmpxchg_local by breaking the following header dependency loop :

linux/kernel.h -> linux/bitops.h -> asm-frv/bitops.h -> asm-frv/atomic.h
  -> asm-frv/system.h ->
  asm-generic/cmpxchg_local.h -> typecheck() defined in linux/kernel.h

and

linux/kernel.h -> linux/bitops.h -> asm-frv/bitops.h -> asm-frv/atomic.h ->
  asm-generic/cmpxchg_local.h -> typecheck() defined in linux/kernel.h

In order to fix this :
- Move the atomic_test_and_ *_mask inlines from asm-frv/atomic.h (why are they
  there at all anyway ? They are not touching atomic_t variables!) to
  asm-frv/bitops.h.

Also fix a build issue with cmpxchg : it does not cast to (unsigned long *)
like other architectures, to deal with it in the cmpxchg_local macro.

FRV builds fine with this patch.

Thanks to Adrian Bunk  for spotting this bug.

Add cmpxchg_local to frv

2008-02-07T16:42:32+00:00

Use the new generic cmpxchg_local (disables interrupt) for 8, 16 and 64 bits
arguments. Use the 32 bits cmpxchg available on the architecture for 32 bits
arguments.

atomic.h: atomic_add_unless as inline. Remove system.h atomic.h circular dependency

2007-05-08T18:15:20+00:00

atomic_add_unless as inline. Remove system.h atomic.h circular dependency.
I agree (with Andi Kleen) this typeof is not needed and more error
prone. All the original atomic.h code that uses cmpxchg (which includes
the atomic_add_unless) uses defines instead of inline functions,
probably to circumvent a circular dependency between system.h and
atomic.h on powerpc (which my patch addresses). Therefore, it makes
sense to use inline functions that will provide type checking.

atomic_add_unless as inline. Remove system.h atomic.h circular dependency.
Digging into the FRV architecture shows me that it is also affected by
such a circular dependency. Here is the diff applying this against the
rest of my atomic.h patches.

It applies over the atomic.h standardization patches.

[PATCH] remove set_wmb - arch removal

2006-07-15T04:56:14+00:00

set_wmb should not be used in the kernel because it just confuses the
code more and has no benefit.  Since it is not currently used in the
kernel this patch removes it so that new code does not include it.

All archs define set_wmb(var, value) to do { var = value; wmb(); }
while(0) except ia64 and sparc which use a mb() instead.  But this is
still moot since it is not used anyway.

Hasn't been tested on any archs but x86 and x86_64 (and only compiled
tested)
