Subject: Re: [PATCH v5 06/12] arm64: elf: Enable BTI at exec based on ELF
program properties
Hi Mark,
Thank you for the patch! Yet something to improve:
[auto build test ERROR on asm-generic/master]
[also build test ERROR on kvmarm/next linus/master v5.5-rc7]
[cannot apply to arm64/for-next/core arm-perf/for-next/perf next-20200124]
[if your patch is applied to the wrong git tree, please drop us a note to help
improve the system. BTW, we also suggest to use '--base' option to specify the
base tree in git format-patch, please see https://stackoverflow.com/a/37406982]
