Subject: [PATCH] x86/kvm: remove unused macro HV_CLOCK_SIZE
Date:   Fri,  6 Nov 2020 16:39:23 +0800
Message-Id: <1604651963-10067-1-git-send-email-alex.shi@linux.alibaba.com>
Precedence: bulk

This macro is useless, and could cause gcc warning:
arch/x86/kernel/kvmclock.c:47:0: warning: macro "HV_CLOCK_SIZE" is not
used [-Wunused-macros]
Let's remove it.
