Subject: [PATCH 1/2] x86/oprofile: fix oprofile for clang build
Date: Fri, 23 Apr 2021 11:43:42 +0200	[thread overview]
Message-ID: <20210423094343.5850-2-roger.pau@citrix.com> (raw)
In-Reply-To: <20210423094343.5850-1-roger.pau@citrix.com>

Clang complains with:

backtrace.c:46:19: error: unused function 'is_32bit_vcpu' [-Werror,-Wunused-function]
static inline int is_32bit_vcpu(struct vcpu *vcpu)

Fix this by guarding the function with CONFIG_COMPAT, as it's only
caller is also doing so.

Fixes: d23d792478d ('x86: avoid building COMPAT code when !HVM && !PV32')
