Subject: [PATCH 0/5] raid6: raid6test build fixes and cleanups

From: WANG Xuerui <git@...0n.name>

Hi,

While working on porting the RAID6 math to the LoongArch SIMD
extensions, I found out the raid6test tool build is broken for some
time (seemingly on all arches), so I took some time to fix it and did
some cleanups while at it.

Before the fix:

> In file included from ../../../include/linux/export.h:5,
>                  from recov.c:16:
> ../../../include/linux/compiler.h:246:10: fatal error: asm/rwonce.h: No such file or directory
>   246 | #include <asm/rwonce.h>
>       |          ^~~~~~~~~~~~~~
> compilation terminated.
> make: *** [Makefile:58: recov.o] Error 1

After the fix I was able to build and test it on x86_64 and loongarch64,
with clean `git status` output after building.

WANG Xuerui (5):
  raid6: remove the <linux/export.h> include from recov.c
  raid6: guard the tables.c include of <linux/export.h> with __KERNEL__
  raid6: test: cosmetic cleanups for the test Makefile
  raid6: test: make sure all intermediate and artifact files are
    .gitignored
  raid6: test: only check for Altivec if building on powerpc hosts
