Subject: [PATCH 0/1] x86/boot/compressed: Use builtin mem functions for decompressor
This patch drops a couple of lines that prevent the decompressor code
from using __builtin_memcpy (and __builtin_memset).
Note that Nick Terrell's patch [0] will apply similar changes directly
in the decompressor code (in-kernel and upstream) for LZ4, and the ZSTD
code already is partially optimized to use __builtin_memcpy for hot
memcpy's, but still improves a little bit more with this patch.
