Just curious: What exact trees do you see this with? This area
changed a lot with the multipage bvec support, and subsequent fixes.
So I'd be really curious if it can be reproduced with Jens' latest
block for-5.2 tree (which should be in latest linux-next).

This series is a split out of the v1 series "Reduce ifdef mess in hugetlbpage.c
and slice.c".
It is also rebased after the series from Aneesh to reduce context size for
Radix.
See

for wide
For PPC32 that's a noop, gcc should be smart enough to ignore it.

This patch defines a subarch specific SLB_ADDR_LIMIT_DEFAULT
to remove the #ifdefs around the setup of mm->context.slb_addr_limit
It also generalises the use of mm_ctx_set_slb_addr_limit() helper.

Hi All,
The kernel now uses Sphinx to generate intelligent and beautiful documentation
from reStructuredText files. I converted all of the Linux ACPI/PCI/X86 docs to
reST format in this serias.
The hieararchy of ACPI docs are based on Corbet's suggestion:
https://lkml.org/lkml/2019/4/3/1047
I did
slice_mask_for_size() only uses mm->context, so hand directly a
pointer to the context. This will help moving the function in
subarch mmu.h in the next patch by avoiding having to include
the definition of struct mm_struct
