[merged mm-nonmm-stable] um-xor-cleanup-xorh.patch removed from -mm tree

[Andrew Morton <akpm@linux-foundation.org>]

The quilt patch titled
     Subject: um/xor: cleanup xor.h
has been removed from the -mm tree.  Its filename was
     um-xor-cleanup-xorh.patch

This patch was dropped because it was merged into the mm-nonmm-stable branch
of git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm

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.
