Subject: [PATCH AUTOSEL 4.19 55/55] MIPS: set mips32r5 for virt extensions
Date: Tue,  6 Jul 2021 07:26:38 -0400	[thread overview]
Message-ID: <20210706112638.2065023-55-sashal@kernel.org> (raw)
In-Reply-To: <20210706112638.2065023-1-sashal@kernel.org>

From: Nick Desaulniers <ndesaulniers@google.com>

[ Upstream commit c994a3ec7ecc8bd2a837b2061e8a76eb8efc082b ]

Clang's integrated assembler only accepts these instructions when the
cpu is set to mips32r5. With this change, we can assemble
malta_defconfig with Clang via `make LLVM_IAS=1`.
