[PATCH v10 00/13] Convert powerpc to default topdown mmap layout (v10)

[PATCH v10 00/13] Convert powerpc to default topdown mmap layout (v10)

[Christophe Leroy]

Rebased on top of v5.18-rc1

This series converts powerpc to default topdown mmap layout.

First patch is a mm fix that should go into v5.18 and stable.

Andrew, can you take it ?

It is a complement/fix of f6795053dac8 ("mm: mmap: Allow for
"high" userspace addresses") for hugetlb. It adds support for "high"
userspace addresses that are optionally supported on the system and
have to be requested via a hint mechanism ("high" addr parameter to mmap).

powerpc requires its own arch_get_unmapped_area() only when
slices are needed, which is only for book3s/64. First part of
the series moves slices into book3s/64 specific directories
and cleans up other subarchitectures.

Last part converts to default topdown mmap layout.

A small modification is done to core mm to allow
powerpc to still provide its own arch_randomize_brk()

Another modification is done to core mm to allow powerpc
to use generic versions of get_unmapped_area functions for Radix
while still providing its own implementation for Hash, the
selection between Radix and Hash being doing at runtime.

Last modification to core mm is to give len and flags to
arch_get_mmap_end().

Changes in v10:
- Moved patch 4 as first patch in order to allow merging a stable backporting independently

Changes in v9:
- v9 was just a split of v8 for tentatively getting the mm part merge through mm and the rest through powerpc tree

Changes in v8:
- Moved patch "sizes.h: Add SZ_1T macro" up from which is already in linux-next but not in Linus tree yet.
- Rebased on today's powerpc/next

Changes in v7:
- Taken into account comments from Catalin (patches 3 and 4)

Changes in v6:
- New patch (patch 4) to take arch_get_mmap_base() and arch_get_mmap_end() into account in generic hugetlb_get_unmapped_area()
- Get back arch_randomize_brk() simplification as it relies on default topdown mmap layout.
- Fixed precedence between || and && in powerpc's arch_get_mmap_end() (patch 9)

Changes in v5:
- Added patch 3
- Added arch_get_mmap_base() and arch_get_mmap_end() to patch 7 to better match original powerpc behaviour
- Switched patched 10 and 11 and performed full randomisation in patch 10 just before switching to default implementation, as suggested by Nic.

Changes in v4:
- Move arch_randomize_brk() simplification out of this series
- Add a change to core mm to enable using generic implementation
while providing arch specific one at the same time.
- Reworked radix get_unmapped_area to use generic implementation
- Rebase on top of Nic's series v6

Changes in v3:
- Fixed missing <linux/elf-randomize.h> in last patch
- Added a patch to move SZ_1T out of drivers/pci/controller/pci-xgene.c

Changes in v2:
- Moved patch 4 before patch 2
- Make generic arch_randomize_brk() __weak
- Added patch 9

[PATCH v10 01/13] mm, hugetlbfs: Allow for "high" userspace addresses

[Christophe Leroy]

This is a complement of f6795053dac8 ("mm: mmap: Allow for "high"
userspace addresses") for hugetlb.

This patch adds support for "high" userspace addresses that are
optionally supported on the system and have to be requested via a hint
mechanism ("high" addr parameter to mmap).

Architectures such as powerpc and x86 achieve this by making changes to
their architectural versions of hugetlb_get_unmapped_area() function.
However, arm64 uses the generic version of that function.

So take into account arch_get_mmap_base() and arch_get_mmap_end() in
hugetlb_get_unmapped_area(). To allow that, move those two macros
out of mm/mmap.c into include/linux/sched/mm.h

If these macros are not defined in architectural code then they default
to (TASK_SIZE) and (base) so should not introduce any behavioural
changes to architectures that do not define them.

For the time being, only ARM64 is affected by this change.

From Catalin (ARM64):
  We should have fixed hugetlb_get_unmapped_area() as well when we
added support for 52-bit VA. The reason for commit f6795053dac8 was to
prevent normal mmap() from returning addresses above 48-bit by default
as some user-space had hard assumptions about this.

It's a slight ABI change if you do this for hugetlb_get_unmapped_area()
but I doubt anyone would notice. It's more likely that the current
behaviour would cause issues, so I'd rather have them consistent.

[PATCH v10 02/13] mm: Allow arch specific arch_randomize_brk() with CONFIG_ARCH_WANT_DEFAULT_TOPDOWN_MMAP_LAYOUT

[Christophe Leroy]

Commit e7142bf5d231 ("arm64, mm: make randomization selected by
generic topdown mmap layout") introduced a default version of
arch_randomize_brk() provided when
CONFIG_ARCH_WANT_DEFAULT_TOPDOWN_MMAP_LAYOUT is selected.

powerpc could select CONFIG_ARCH_WANT_DEFAULT_TOPDOWN_MMAP_LAYOUT
but needs to provide its own arch_randomize_brk().

In order to allow that, define generic version of arch_randomize_brk()
as a __weak symbol.

[PATCH v10 03/13] mm, hugetlbfs: Allow an arch to always use generic versions of get_unmapped_area functions

[Christophe Leroy]

Unlike most architectures, powerpc can only define at runtime
if it is going to use the generic arch_get_unmapped_area() or not.

Today, powerpc has a copy of the generic arch_get_unmapped_area()
because when selection HAVE_ARCH_UNMAPPED_AREA the generic
arch_get_unmapped_area() is not available.

Rename it generic_get_unmapped_area() and make it independent of
HAVE_ARCH_UNMAPPED_AREA.

Do the same for arch_get_unmapped_area_topdown() versus
HAVE_ARCH_UNMAPPED_AREA_TOPDOWN.

Do the same for hugetlb_get_unmapped_area() versus
HAVE_ARCH_HUGETLB_UNMAPPED_AREA.

[PATCH v10 04/13] mm: Add len and flags parameters to arch_get_mmap_end()

[Christophe Leroy]

Powerpc needs flags and len to make decision on arch_get_mmap_end().

So add them as parameters to arch_get_mmap_end().

[PATCH v10 05/13] powerpc/mm: Move vma_mmu_pagesize()

[Christophe Leroy]

vma_mmu_pagesize() is only required for slices,
otherwise there is a generic weak version doing the
exact same thing.

Move it to slice.c

[PATCH v10 06/13] powerpc/mm: Make slice specific to book3s/64

[Christophe Leroy]

Since commit 555904d07eef ("powerpc/8xx: MM_SLICE is not needed
anymore") only book3s/64 selects CONFIG_PPC_MM_SLICES.

Move slice.c into mm/book3s64/

Move necessary stuff in asm/book3s/64/slice.h and
remove asm/slice.h

[PATCH v10 08/13] powerpc/mm: Use generic_get_unmapped_area() and call it from arch_get_unmapped_area()

[Christophe Leroy]

Use the generic version of arch_get_unmapped_area() which
is now available at all time instead of its copy
radix__arch_get_unmapped_area()

To allow that for PPC64, add arch_get_mmap_base() and
arch_get_mmap_end() macros.

Instead of setting mm->get_unmapped_area() to either
arch_get_unmapped_area() or generic_get_unmapped_area(),
always set it to arch_get_unmapped_area() and call
generic_get_unmapped_area() from there when radix is enabled.

Do the same with radix__arch_get_unmapped_area_topdown()

[PATCH v10 10/13] powerpc/mm: Move get_unmapped_area functions to slice.c

[Christophe Leroy]

hugetlb_get_unmapped_area() is now identical to the
generic version if only RADIX is enabled, so move it
to slice.c and let it fallback on the generic one
when HASH MMU is not compiled in.

Do the same with arch_get_unmapped_area() and
arch_get_unmapped_area_topdown().

[PATCH v10 11/13] powerpc/mm: Enable full randomisation of memory mappings

[Christophe Leroy]

Do like most other architectures and provide randomisation also to
"legacy" memory mappings, by adding the random factor to
mm->mmap_base in arch_pick_mmap_layout().

See commit 8b8addf891de ("x86/mm/32: Enable full randomization on
i386 and X86_32") for all explanations and benefits of that mmap
randomisation.

At the moment, slice_find_area_bottomup() doesn't use mm->mmap_base
but uses the fixed TASK_UNMAPPED_BASE instead.
slice_find_area_bottomup() being used as a fallback to
slice_find_area_topdown(), it can't use mm->mmap_base
directly.

Instead of always using TASK_UNMAPPED_BASE as base address, leave
it to the caller. When called from slice_find_area_topdown()
TASK_UNMAPPED_BASE is used. Otherwise mm->mmap_base is used.

[PATCH v10 12/13] powerpc/mm: Convert to default topdown mmap layout

[Christophe Leroy]

Select CONFIG_ARCH_WANT_DEFAULT_TOPDOWN_MMAP_LAYOUT and
remove arch/powerpc/mm/mmap.c

This change reuses the generic framework added by
commit 67f3977f805b ("arm64, mm: move generic mmap layout
functions to mm") without any functional change.

Comparison between powerpc implementation and the generic one:
- mmap_is_legacy() is identical.
- arch_mmap_rnd() does exactly the same allthough it's written
slightly differently.
- MIN_GAP and MAX_GAP are identical.
- mmap_base() does the same but uses STACK_RND_MASK which provides
the same values as stack_maxrandom_size().
- arch_pick_mmap_layout() is identical.

[PATCH v10 13/13] powerpc: Simplify and move arch_randomize_brk()

[Christophe Leroy]

arch_randomize_brk() is only needed for hash on book3s/64, for other
platforms the one provided by the default mmap layout is good enough.

Move it to hash_utils.c and use randomize_page() like the generic one.

And properly opt out the radix case instead of making an assumption
on mmu_highuser_ssize.

Also change to a 32M range like most other architectures instead of 8M.

This breaks the build when CONFIG_PPC_64S_HASH_MMU is not set.

The root cause is that arch/powerpc/mm/book3s64/slice.c is not built if
!CONFIG_PPC_64S_HASH_MMU.
The commit f693d38d9468 (powerpc/mm: Remove CONFIG_PPC_MM_SLICES,
2022-04-09) builds slice.c only if CONFIG_PPC_64S_HASH_MMU.

I'm wondering if these functions have to be moved in slice.c

Attached is the config file I used.

I think the root cause is slice.h is being included allthough 
!CONFIG_PPC_64S_HASH_MMU, which leads to HAVE_ARCH_UNMAPPED_AREA and 
HAVE_ARCH_UNMAPPED_AREA_TOPDOWN being defined while they shouldn't

Wondering why I didn't see that before.

slice.h gets included via asm/book3s/64/mmu-hash.h

I was able to build microwatt_defconfig with the following changes:
