Subject: [PATCH 4.14 11/52] powerpc: Force inlining of cpu_has_feature() to avoid build failure
Date: Mon, 5 Apr 2021 10:53:37 +0200 [thread overview]
Message-ID: <20210405085022.369116756@linuxfoundation.org> (raw)
In-Reply-To: <20210405085021.996963957@linuxfoundation.org>
From: Christophe Leroy <christophe.leroy@csgroup.eu>
[ Upstream commit eed5fae00593ab9d261a0c1ffc1bdb786a87a55a ]
The code relies on constant folding of cpu_has_feature() based
on possible and always true values as defined per
CPU_FTRS_ALWAYS and CPU_FTRS_POSSIBLE.
Build failure is encountered with for instance
book3e_all_defconfig on kisskb in the AMDGPU driver which uses
cpu_has_feature(CPU_FTR_VSX_COMP) to decide whether calling
kernel_enable_vsx() or not.
The failure is due to cpu_has_feature() not being inlined with
that configuration with gcc 4.9.
In the same way as commit acdad8fb4a15 ("powerpc: Force inlining of
mmu_has_feature to fix build failure"), for inlining of
cpu_has_feature().
