Hi Ian,
This commit breaks the Arm build (and cross compilation for Arm on x86):
$ make ARCH=arm64 CROSS_COMPILE=aarch64-linux-gnu-
Something like this, but I won't paste the whole output because it's huge:
tools/include/linux/ring_buffer.h: In function ‘ring_buffer_read_head’:
tools/include/asm/../../arch/arm64/include/asm/barrier.h:72:35: error: ‘__u8_alias_t’ undeclared (first use in this function) 72 | : "=r" (*(__u8_alias_t *)__u.__c) \ | ^~~~~~~~~~~~ tools/include/linux/ring_buffer.h:59:16: note: in expansion of macro ‘smp_load_acquire’ 59 | return smp_load_acquire(&base->data_head); | ^~~~~~~~~~~~~~~~
Thanks James
