Re: [PATCH 03/25] um/xor: don't override XOR_SELECT_TEMPLATE

----- Ursprüngliche Mail -----

Von: "hch" [off-list ref]
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.

IIRC Johannes added XOR_SELECT_TEMPLATE() here to skip
the template selection logic because it didn't work with time travel mode.

Johannes, can you please test whether this change does not break
time travel mode?

Thanks,
