Subject: [PATCH 03/25] um/xor: don't override XOR_SELECT_TEMPLATE
Date: Thu, 26 Feb 2026 07:10:15 -0800 [thread overview]
Message-ID: <20260226151106.144735-4-hch@lst.de> (raw)
In-Reply-To: <20260226151106.144735-1-hch@lst.de>
XOR_SELECT_TEMPLATE is only ever called with a NULL argument, so all the
ifdef'ery doesn't do anything. With our without this, the time travel
mode should work fine on CPUs that support AVX2, as the AVX2
implementation is forced in this case, and won't work otherwise.
