2019-02-18	arm64/neon: Disable -Wincompatible-pointer-types when building with Clang	Nathan Chancellor
	After commit cc9f8349cb33 ("arm64: crypto: add NEON accelerated XOR implementation"), Clang builds for arm64 started failing with the following error message. arch/arm64/lib/xor-neon.c:58:28: error: incompatible pointer types assigning to 'const unsigned long ' from 'uint64_t ' (aka 'unsigned long long *') [-Werror,-Wincompatible-pointer-types] v3 = veorq_u64(vld1q_u64(dp1 + 6), vld1q_u64(dp2 + 6)); ^~~~~~~~ /usr/lib/llvm-9/lib/clang/9.0.0/include/arm_neon.h:7538:47: note: expanded from macro 'vld1q_u64' __ret = (uint64x2_t) __builtin_neon_vld1q_v(__p0, 51); \ ^~~~ There has been quite a bit of debate and triage that has gone into figuring out what the proper fix is, viewable at the link below, which is still ongoing. Ard suggested disabling this warning with Clang with a pragma so no neon code will have this type of error. While this is not at all an ideal solution, this build error is the only thing preventing KernelCI from having successful arm64 defconfig and allmodconfig builds on linux-next. Getting continuous integration running is more important so new warnings/errors or boot failures can be caught and fixed quickly.

2018-12-06	arm64/neon: add workaround for ambiguous C99 stdint.h types	Jackie Liu
	In a way similar to ARM commit 09096f6a0ee2 ("ARM: 7822/1: add workaround for ambiguous C99 stdint.h types"), this patch redefines the macros that are used in stdint.h so its definitions of uint64_t and int64_t are compatible with those of the kernel. This patch comes from: https://patchwork.kernel.org/patch/3540001/ Wrote by: Ard Biesheuvel <ard.biesheuvel@linaro.org> We mark this file as a private file and don't have to override asm/types.h Signed-off-by: Jackie Liu <liuyun01@kylinos.cn> Reviewed-by: Ard Biesheuvel <ard.biesheuvel@linaro.org> Signed-off-by: Will Deacon <will.deacon@arm.com>
