From: Mark Brown Date: Wed, 16 Aug 2023 18:39:32 +0000 (+0100) Subject: kselftest/arm64: Fix hwcaps selftest build X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=94f23ac36f8b3c2140b00d78131c8df41cd9ac5d;p=linux.git kselftest/arm64: Fix hwcaps selftest build The hwcaps selftest currently relies on the assembler being able to assemble the crc32w instruction but this is not in the base v8.0 so is not accepted by the standard GCC configurations used by many distributions. Switch to manually encoding to fix the build.
