[PATCH] [BUGFIX] Fix build error caused by an undefinition of thekvm_write_tsc_offset tracepoint for x86_32

From: Yoshihiro YUNOMAE
Date: Tue Jun 25 2013 - 06:17:09 EST


Fix build error caused by an undefinition of the kvm_write_tsc_offset
tracepoint for x86_32.
Since the tracepoint in trace.h was defined for CONFIG_X86_64, kernel build
on i386 was failed.
