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
