Nice to see all of these!

All of these sound good.
I'm not sure about whether many people would be interested in x32, though?...

Something other than standard crypt (isn't that DES, which can be cracked
in a day on the right machine?) would be one of the more interesting ones
from my perspective.  Remembering the recent test results, I'd be hoping
for bcrypt as well (it's where OpenCL cracking gets the least benefit).

I may be sending a patch or two to adjust io.h / io*.c as well.
(move to per-architecture, perhaps; add bits/io.h based on klibc's
sys/io.h (?) )
Also, once I figure out how syscall.list* maps to the syscall() interface
in musl, I may send a patch to support syscalls 113 & 166
(vm86(old)/vm86(plus))
*glibc and some other libc versions just have a list describing the
calling convention, name, and so on for each syscall. This somehow gets
converted to  functions.
