Subject: Re: [PATCH] [BUGFIX] Fix build error caused by an undefinition
 of the kvm_write_tsc_offset tracepoint for x86_32

Hi Gleb,

Thank you for applying my patch.
I received a mail of build error for i386, so I fixed the problem.
Since the tracepoint was defined only for x86_64, build was failed in
x86_32.

Would you apply this patch to kvm-tree?
Sorry for the inconvenience this may cause.

Thank you,
Yoshihiro YUNOMAE
