Subject: [PATCH] microblaze: generic atomic64 support

This tiny patch adds generic atomic64 support for the Microblaze
architecture.

The patch is against the latest linux-2.6-microblaze tree. It also
fixes the kernel build for microblaze:

CC kernel/trace/trace_clock.o 
kernel/trace/trace_clock.c:117: error: expected '=', ',', ';', 'asm' 
or '__attribute__' before 'trace_counter' 
kernel/trace/trace_clock.c: In function 'trace_clock_counter': 
kernel/trace/trace_clock.c:126: error: implicit declaration of 
function 'atomic64_add_return' 
kernel/trace/trace_clock.c:126: error: 'trace_counter' undeclared 
(first use in this function) 
kernel/trace/trace_clock.c:126: error: (Each undeclared identifier is 
reported only once 
kernel/trace/trace_clock.c:126: error: for each function it appears in.) 
make[2]: *** [kernel/trace/trace_clock.o] Error 1 
make[1]: *** [kernel/trace] Error 2 
make: *** [kernel] Error 2 

(the patch got corrupted beforehand, to that's why the resend)
