Re: [PATCH] bpf: samples: exclude asm/sysreg.h for arm64

commit 338d4f49d6f7114a017d294ccf7374df4f998edc ("arm64: kernel: Add support for Privileged Access Never") includes sysreg.h into futex.h and uaccess.h. But, the inline assembly used by asm/sysreg.h is incompatible with llvm so it will cause BPF samples build failure for ARM64. Since sysreg.h is useless for BPF samples, just exclude it from Makefile via defining __ASM_SYSREG_H.

not the prettiest fix, but good enough for sample code. Acked-by: Alexei Starovoitov ast@kernel.org
