Hello all,
This series includes the bulk of libc-related compile fixes accumulated to support systems using musl, with smaller numbers to follow. These patches are simple and straightforward, and the series has been tested with the kernel-patches/bpf CI and locally using mips64el-gcc/musl-libc and QEMU with an OpenWrt rootfs.
The patches address a few general categories of libc portability issues:
- missing, redundant or incorrect include headers
- disabled GNU header extensions (i.e. missing #define _GNU_SOURCE)
- issues with types and casting
Feedback and suggestions for improvement are welcome!
Thanks, Tony

I squashed the above three patches into one, as they are the same kind of fix with the same reasoning. The rest at least have a specific error example, so I didn't touch them.
But generally speaking, I think it's fair to combine the same kind of fixes across a few files (for the future).
Applied to bpf-next, thanks.
