cmpxchg() in recent kernels

[Alex Sverdlin]

Hello!

I've probably missed something, but how to compile recent kernels on ARM?
I've been using GCC 3.4.3 from Cirrus for my EP9302 boards up to 2.6.35.4
But 2.6.36-rc and upper won't compile anymore.
The problem is appearing in multiplatform code of cmpxchg() function.
First in kernel/pid.c (2.6.36-rc4 - 2.6.36-rc6)
Then 4 times in 2.6.36-rc7-next... atomic_cmpxchg compiles fine, and when I
replace cmpxhg with atomic_ version, everything compiles fine.

Here is output of make from 2.6.36-rc7-next:
...
