Are there any problems with this patch?
The latest patch doing these changes to the kernel can be found here:
https://patchwork.kernel.org/patch/10139199/
It is doing the same thing as this patch:
http://git.musl-libc.org/cgit/musl/commit/?id=04983f2272382af92eb8f8838964ff944fbb8258
just for the two other effected files.
