Can you update the selftest too, please? Last time I looked at that it had typo for the powerpc check and looked pretty unloved...

I actually sent two patches doing that 10 minutes before that one, but I forgot to CC: you on this: https://lkml.org/lkml/2015/9/22/176 Feel free to chime into the discussion ;-) Cheers, Andre. > Will > >> Signed-off-by: Andre Przywara <andre.przywara@arm.com> >> --- >> include/uapi/asm-generic/unistd.h | 4 +++- >> 1 file changed, 3 insertions(+), 1 deletion(-) >> >> diff --git a/include/uapi/asm-generic/unistd.h b/include/uapi/asm-generic/unistd.h >> index 8da542a..82c91bc 100644 >> --- a/include/uapi/asm-generic/unistd.h >> +++ b/include/uapi/asm-generic/unistd.h >> @@ -711,9 +711,11 @@ __SYSCALL(__NR_bpf, sys_bpf) >> __SC_COMP(__NR_execveat, sys_execveat, compat_sys_execveat) >> #define __NR_membarrier 282 >> __SYSCALL(__NR_membarrier, sys_membarrier) >> +#define __NR_userfaultfd 283 >> +__SYSCALL(__NR_userfaultfd, sys_userfaultfd) >> >> #undef __NR_syscalls >> -#define __NR_syscalls 283 >> +#define __NR_syscalls 284 >> >> /* >> * All syscalls below here should go away really, >> -- >> 2.5.1 >> > -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
