Cool, the above was done as copies, why not the rest? IIRC you mentioned
some reasoning behind that decision, but we need it spelled out here.
For instance, I went on and look at arch/xtensa/include/uapi/asm/mman.h,
and couldn't find why we shouldn't copy it just like the three files
above.
I'm looking now at why the build breaks in so many systems, first hunch
is that bits/ part (the ones without the failure details probably have
the same errors), alpine uses musl libc, but some that broke are glibc
based.
