Subject[PATCH v12 00/22] selftests, powerpc, x86 : Memory Protection Keys
Date
Memory protection keys enables an application to protect its address space from
inadvertent access by its own code.

This feature is now enabled on powerpc architecture and integrated in
4.16-rc1. The patches move the selftests to arch neutral directory
and enhance their test coverage.

Test
----
Verified for correctness on powerpc
and on x86 architectures(using EC2 ubuntu VM instance).

History:
-------

version 12:
(1) fixed the offset of pkey field in the siginfo structure for
x86_64 and powerpc. And tries to use the actual field
if the headers have it defined.
version 11:
(1) fixed a deadlock in the ptrace testcase.

version 10 and prior:
(1) moved the testcase to arch neutral directory
(2) split the changes into incremental patches.
