Commit 129766708 ("x86/efi: Only map RAM into EFI page tables if in
mixed-mode") stopped creating 1:1 mapping for all RAM in case of running
in native 64bit mode.
It turns out though that there are 64bit EFI implementations in the wild

This patch updates LZ4 kernel module to LZ4 v1.7.3 by Yann Collet.
The kernel module is inspired by the previous work by Chanho Min.
The updated LZ4 module will not break existing code since the patchset
contains appropriate changes.

Generated with checkpatch.pl --fix-inplace, some manual fixes for
cases where checkpatch fixed one out of multiple lines of mis-indented
function parameters, and then git add -p out of the results.
I skipped some fixes that should probably instead be replaced with the
BIT() macro.

This patch removes the functions introduced as wrappers for providing
backwards compatibility to the prior LZ4 version.
They're not needed anymore since there's no callers left.

This patchset is for updating the LZ4 compression module to a version based
on LZ4 v1.7.3 allowing to use the fast compression algorithm aka LZ4 fast
which provides an "acceleration" parameter as a tradeoff between
high compression ratio and high compression speed.
We want to use LZ4 fast in orde
