Subject: [PATCH AUTOSEL 4.9 03/15] KVM: PPC: Move and undef TRACE_INCLUDE_PATH/FILE
Date: Thu, 22 Nov 2018 14:56:09 -0500 [thread overview]
Message-ID: <20181122195621.13776-3-sashal@kernel.org> (raw)
In-Reply-To: <20181122195621.13776-1-sashal@kernel.org>
From: Scott Wood <oss@buserror.net>
[ Upstream commit 28c5bcf74fa07c25d5bd118d1271920f51ce2a98 ]
TRACE_INCLUDE_PATH and TRACE_INCLUDE_FILE are used by
<trace/define_trace.h>, so like that #include, they should
be outside #ifdef protection.
They also need to be #undefed before defining, in case multiple trace
headers are included by the same C file. This became the case on
book3e after commit cf4a6085151a ("powerpc/mm: Add missing tracepoint for
tlbie"), leading to the following build error:
CC arch/powerpc/kvm/powerpc.o
