Let's instead put this (note it's without braces) in macros like these
#define KVM_GENERIC_VM_STATS()
\
STATS_DESC_COUNTER("remote_tlb_flush"),
#define KVM_GENERIC_VCPU_STATS(...)
\
STATS_DESC_COUNTER("halt_successful_poll"),
\
STATS_DESC_COUNTER("halt_attempted_poll"),
\
STATS_DESC_COUNTER("halt_poll_invalid"),
\
STATS_DESC_COUNTER("halt_wakeup"),
\
STATS_DESC_TIME_NSEC("halt_poll_success_ns"),
\
STATS_DESC_TIME_NSEC("halt_poll_fail_ns"),
and it can be used in the arch files. In fact it can even be added in patch 1
and
switched to STATS_DESC_* here.

I just remember that the reason I used braces is due to following
error from checkpatch.pl:
ERROR: Macros with complex values should be enclosed in parentheses
No, just ignore the bogus error from checkpatch.pl. But, thanks for
checking!
