The purpose of this series is to reduce the amount of #ifdefs
in ptrace.c
Link: https://github.com/linuxppc/issues/issues/128
Tentatively build checked on kisskb allthough kisskb seems overloaded and
failing to complete the tests.
See
http://kisskb.ellerman.id.au/kisskb/branch/chleroy/head/ff12
In order to allow splitting of ptrace depending on the
different CONFIG_ options, create a subdirectory dedicated to
ptrace and move ptrace.c and ptrace32.c into it.

This adds new tests validating arch page table helpers for these following
core memory features. These tests create and test specific mapping types at
various page table levels.
* SPECIAL mapping
* PROTNONE mapping
* DEVMAP mapping
* SOFTDIRT

The __pXd_offset() macros are identical to the pXd_index() macros and there
is no point to keep both of them. All architectures define and use
pXd_index() so let's keep only those to make mips consistent with the rest
of the kernel.

Hi,
These patches convert several architectures to use page table folding and
remove __ARCH_HAS_5LEVEL_HACK along with include/asm-generic/5level-fixup.h
and include/asm-generic/pgtable-nop4d-hack.h. With that we'll have a single
