1 Fix libc kernel headers conflict
3 Add missing kernel headers to fix conflicts with toolchain provided kernel
4 headers of older versions.
6 This patch is equivalent to upstream commit 6c7f4215003 ("build: distribute
7 in.h in6.h libc-compat.h"). These files are present in upstream git repo, but
8 are missing from the distributed tarball.

615 + * Compatibility interface for userspace libc header coordination:
616 + *
617 + * Define compatibility macros that are used to control the inclusion or
618 + * exclusion of UAPI structures and definitions in coordination with another
619 + * userspace C library.
620 + *
621 + * This header is intended to solve the problem of UAPI definitions that
622 + * conflict with userspace definitions. If a UAPI header has such conflicting
623 + * definitions then the solution is as follows:
624 + *
625 + * * Synchronize the UAPI header and the libc headers so either one can be
626 + * used and such that the ABI is preserved. If this is not possible then
627 + * no simple compatibility interface exists (you need to write translating
628 + * wrappers and rename things) and you can't use this interface.
629 + *
630 + * Then follow this process:
631 + *
632 + * (a) Include libc-compat.h in the UAPI header.
633 + * e.g. #include <linux/libc-compat.h>
634 + * This include must be as early as possible.
635 + *
636 + * (b) In libc-compat.h add enough code to detect that the comflicting
637 + * userspace libc header has been included first.
638 + *
639 + * (c) If the userspace libc header has been included first define a set of
640 + * guard macros of the form __UAPI_DEF_FOO and set their values to 1, else
641 + * set their values to 0.
642 + *
643 + * (d) Back in the UAPI header with the conflicting definitions, guard the
644 + * definitions with:
645 + * #if __UAPI_DEF_FOO
646 + * ...
647 + * #endif
648 + *
649 + * This fixes the situation where the linux headers are included *after* the
650 + * libc headers. To fix the problem with the inclusion in the other order the
651 + * userspace libc headers must be fixed like this:
652 + *
653 + * * For all definitions that conflict with kernel definitions wrap those
654 + * defines in the following:
655 + * #if !__UAPI_DEF_FOO
656 + * ...
657 + * #endif
658 + *
659 + * This prevents the redefinition of a construct already defined by the kernel.
