Subject: [PATCH] x86/Hyper-V: Fix build error with CONFIG_HYPERV_TSCPAGE=N
Date: Thu, 22 Aug 2019 13:38:52 +0800	[thread overview]
Message-ID: <20190822053852.239309-1-Tianyu.Lan@microsoft.com> (raw)

From: Tianyu Lan <Tianyu.Lan@microsoft.com>

Both Hyper-V tsc page and Hyper-V tsc MSR code use variable
hv_sched_clock_offset for their sched clock callback and so
define the variable regardless of CONFIG_HYPERV_TSCPAGE setting.

Signed-off-by: Tianyu Lan <Tianyu.Lan@microsoft.com>
