Subject: [PATCH 03/27] um/xor: cleanup xor.h
Date: Wed, 11 Mar 2026 08:03:35 +0100 [thread overview]
Message-ID: <20260311070416.972667-4-hch@lst.de> (raw)
In-Reply-To: <20260311070416.972667-1-hch@lst.de>
Since commit c055e3eae0f1 ("crypto: xor - use ktime for template
benchmarking") the benchmarking works just fine even for TT_MODE_INFCPU,
so drop the workarounds. Note that for CPUs supporting AVX2, which
includes almost everything built in the last 10 years, the AVX2
implementation is forced anyway.
CONFIG_X86_32 is always correctly set for UM in arch/x86/um/Kconfig,
so don't override it either.
