Catalin Marinas 7606c37d4a arm64: Do not export the compat-specific definitions to the user
This patch adds #ifdef __KERNEL__ guards around the COMPAT_* definitions
to avoid exporting them to user. AArch32 user requiring the kernel
headers must use those generated with ARCH=arm.

Will Deacon 27aa55c5e5 arm64: ptrace: remove obsolete ptrace request numbers from user headers
The use of regsets has removed the need for many private ptrace requests,
so remove the corresponding definitions from the user-visible ptrace.h

Catalin Marinas 60ffc30d56 arm64: Exception handling
The patch contains the exception entry code (kernel/entry.S), pt_regs
structure and related accessors, undefined instruction trapping and
stack tracing.

AArch64 Linux kernel (including kernel threads) runs in EL1 mode using
the SP1 stack. The vectors don't have a fixed address, only alignment
(2^11) requirements.
