Subject: [PATCH 0/3] compat vdso cleanups
Date: Tue, 12 Oct 2021 16:46:03 -0700	[thread overview]
Message-ID: <20211012234606.91717-1-ndesaulniers@google.com> (raw)

Three fixes for compat vdso, the first two are related, the third is
standalone.

The first two fix a warning observed for `mrproper` targets when
$(CROSS_COMPILE_COMPAT)gcc is not in the $PATH.

The third makes is so that CROSS_COMPILE_COMPAT is not necessary to
select COMPAT_VDSO when using clang+lld.

Based on arm64/linux.git/for-next/misc.

Nick Desaulniers (3):
  arm64: vdso32: drop the test for dmb ishld
  arm64: vdso32: lazily invoke COMPAT_CC
  arm64: vdso32: require CROSS_COMPILE_COMPAT for gcc+bfd
