Subject: [PATCH] arm64: vdso32: drop -no-integrated-as flag
Date: Tue, 13 Apr 2021 16:06:06 -0700	[thread overview]
Message-ID: <20210413230609.3114365-1-ndesaulniers@google.com> (raw)

Clang can assemble these files just fine; this is a relic from the top
level Makefile conditionally adding this.

To test building:
$ ARCH=arm64 CROSS_COMPILE=aarch64-linux-gnu- \
  CROSS_COMPILE_COMPAT=arm-linux-gnueabi- make LLVM=1 LLVM_IAS=1 \
  defconfig arch/arm64/kernel/vdso32/
