Subject: [PATCH v3 00/14] mm: remove __ARCH_HAS_5LEVEL_HACK
Date: Thu, 27 Feb 2020 10:45:54 +0200 [thread overview]
Message-ID: <20200227084608.18223-1-rppt@kernel.org> (raw)
From: Mike Rapoport <rppt@linux.ibm.com>
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
and consistent way of dealing with page table folding instead of a mix of
three existing options.
The changes are mostly about mechanical replacement of pgd accessors with p4d
ones and the addition of higher levels to page table traversals.
v3:
* add Christophe's patch that removes ppc32 get_pteptr()
* reduce amount of upper layer walks in powerpc
v2:
* collect per-arch patches into a single set
* include Geert's update of 'sh' printing messages
* rebase on v5.6-rc1+
Christophe Leroy (1):
powerpc/32: drop get_pteptr()
Geert Uytterhoeven (1):
sh: fault: Modernize printing of kernel messages
Mike Rapoport (12):
arm/arm64: add support for folded p4d page tables
h8300: remove usage of __ARCH_USE_5LEVEL_HACK
hexagon: remove __ARCH_USE_5LEVEL_HACK
ia64: add support for folded p4d page tables
nios2: add support for folded p4d page tables
openrisc: add support for folded p4d page tables
powerpc: add support for folded p4d page tables
sh: drop __pXd_offset() macros that duplicate pXd_index() ones
sh: add support for folded p4d page tables
unicore32: remove __ARCH_USE_5LEVEL_HACK
asm-generic: remove pgtable-nop4d-hack.h
mm: remove __ARCH_HAS_5LEVEL_HACK and
include/asm-generic/5level-fixup.h
