[PATCH v2 0/2] arm64: Unimplemented syscall kernel message

[Michael Weiser]

Hi Will,

I've dropped the message from the compat change, which makes it much
more straight-forward. We are still dropping the offending log message
from do_ni_syscall(). The second change now just mirrors the part of arm
behaviour in compat_arm_syscall() that raises SIGILL for (most)
unimplemented syscalls. Finally show_unhandled_signals is disabled by
default.

All are compile-tested as well as manually prodded with some randomly
chosen syscall numbers from aarch64 and arm-eabi binaries while running
under qemu-system-aarch64. New show_unhandled_signals defaults and
enabling via /proc/sys have been tested with a minimal segfaulting test
program.

Thanks,
Michael
