Subject: [PATCH v2 0/2] arm64: Simplify gas LSE support detection
Date: Wed, 15 Jan 2020 11:30:06 +0000	[thread overview]
Message-ID: <20200115113008.3334-1-catalin.marinas@arm.com> (raw)

Version two of the patch series moving the LSE assembler support
detection from Makefile to Kconfig.

Changes since v1 [1]:

- Re-introduce the Makefile warning if the .config contains
  CONFIG_ARM64_USE_LSE_ATOMICS but the assembler does not support the
  feature, disabling CONFIG_ARM64_LSE_ATOMICS.

  kbuild: Add support for 'as-instr' to be used in Kconfig files
  arm64: Move the LSE gas support detection to Kconfig
