<sys/linux-syscalls.h> only contains constants for the syscalls we're generating stubs for. We want all the syscalls available on the architecture in question. Keep using <sys/linux-syscalls.h> on ARM for now because the __NR_ARM_set_tls and __NR_ARM_cacheflush values aren't in <asm/unistd.h>. Change-Id: I66683950d87d9b18d6107d0acc0ed238a4496f44
