[PATCH v6 07/13] arm64: add basic pointer authentication support

2018-12-07 Thread Kristina Martsenko
From: Mark Rutland This patch adds basic support for pointer authentication, allowing userspace to make use of APIAKey, APIBKey, APDAKey, APDBKey, and APGAKey. The kernel maintains key values for each process (shared by all threads within), which are initialised to random values at exec() time.
