tools arch uapi: Copy missing unistd.h headers for arc, hexagon and riscv Since those were introduced in: c8ce48f06503 ("asm-generic: Make time32 syscall numbers optional") But when the asm-generic/unistd.h was sync'ed with tools/ in: 1a787fc5ba18 ("tools headers uapi: Sync copy of asm-generic/unistd.h with the kernel sources") I forgot to copy the files for the architectures that define __ARCH_WANT_TIME32_SYSCALLS, so the perf build was breaking there, as reported by Vineet Gupta for the ARC architecture. After updating my ARC container to use the glibc based toolchain + cross building libnuma, zlib and elfutils, I finally managed to reproduce the problem and verify that this now is fixed and will not regress as will be tested before each pull req sent upstream.

asm-generic: Unify uapi bitsperlong.h for arm64, riscv and loongarch Now we specify the minimal version of GCC as 5.1 and Clang/LLVM as 11.0.0 in Documentation/process/changes.rst, __CHAR_BIT__ and __SIZEOF_LONG__ are usable, it is probably fine to unify the definition of __BITS_PER_LONG as (__CHAR_BIT__ * __SIZEOF_LONG__) in asm-generic uapi bitsperlong.h. In order to keep safe and avoid regression, only unify uapi bitsperlong.h for some archs such as arm64, riscv and loongarch which are using newer toolchains that have the definitions of __CHAR_BIT__ and __SIZEOF_LONG__.

asm-generic: partially revert "Unify uapi bitsperlong.h for arm64, riscv and loongarch" Unifying the asm-generic headers across 32-bit and 64-bit architectures based on the compiler provided macros was a good idea and appears to work with all user space, but it caused a regression when building old kernels on systems that have the new headers installed in /usr/include, as this combination trips an inconsistency in the kernel's own tools/include headers that are a mix of userspace and kernel-internal headers. This affects kernel builds on arm64, riscv64 and loongarch64 systems that might end up using the "#define __BITS_PER_LONG 32" default from the old tools headers. Backporting the commit into stable kernels would address this, but it would still break building kernels without that backport, and waste time for developers trying to understand the problem. arm64 build machines are rather common, and on riscv64 this can also happen in practice, but loongarch64 is probably new enough to not be used much for building old kernels, so only revert the bits for arm64 and riscv.
