Manual changes: cpp.py: cope with macros that refer to other macros. defaults.py: x86 no longer always implies __i386__; use __i386__ to replace the kernel CONFIG_X86_32 flag. asm/page.h: the upstream page.h isn't a uapi header and no longer includes the stuff we were using it for. Let's just have our own static file, since it's the same for all our architectures (both 32- and 64-bit). sys/select.h: we used to use the various FD_SET-related macros from the kernel header files, but they've gone. Adjust by adding trivial equivalent definitions. Automated changes: libc/kernel/arch-x86, libc/kernel/common: regenerated from external/kernel-headers.

*** contains no copyrightable information.

*** To edit the content of this header, modify the corresponding
