Subject: [PATCH v7 00/12] huge vmalloc mappings
Date: Wed, 26 Aug 2020 00:57:41 +1000 [thread overview]
Message-ID: <20200825145753.529284-1-npiggin@gmail.com> (raw)
I think it's ready to go into -mm if it gets acks for the arch
changes.
Thanks,
Nick
Since v6:
- Fixed a false positive warning introduced in patch 2, found by
kbuild test robot.
Since v5:
- Split arch changes out better and make the constant folding work
- Avoid most of the 80 column wrap, fix a reference to lib/ioremap.c
- Fix compile error on some archs
Since v4:
- Fixed an off-by-page-order bug in v4
- Several minor cleanups.
- Added page order to /proc/vmallocinfo
- Added hugepage to alloc_large_system_hage output.
- Made an architecture config option, powerpc only for now.
Since v3:
- Fixed an off-by-one bug in a loop
- Fix !CONFIG_HAVE_ARCH_HUGE_VMAP build fail
- Hopefully this time fix the arm64 vmap stack bug, thanks Jonathan
Cameron for debugging the cause of this (hopefully).
Since v2:
- Rebased on vmalloc cleanups, split series into simpler pieces.
- Fixed several compile errors and warnings
- Keep the page array and accounting in small page units because
struct vm_struct is an interface (this should fix x86 vmap stack debug
assert). [Thanks Zefan]
