X-Git-Tag: v2.6.30-rc5~75
X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=a5fc1abe438b87a9d128beebc377f78e2681a76d;p=pandora-kernel.git

atomic: fix atomic_long_cmpxchg/xchg for 64 bit architectures

On a linux-next allyesconfig build:

kernel/trace/ring_buffer.c:1726:
	warning: passing argument 1 of 'atomic_cmpxchg' from incompatible pointer type
linux-next/arch/s390/include/asm/atomic.h:112:
	note: expected 'struct atomic_t *' but argument is of type 'struct atomic64_t *'

atomic_long_cmpxchg and atomic_long_xchg are incorrectly defined for 64
bit architectures.  They should be mapped to the atomic64_* variants.
