arm64/neon: add workaround for ambiguous C99 stdint.h types (21e28547) · Commits · 戴 / test

In a way similar to ARM commit ("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:
