Subject: [PATCH v4 0/8] huge vmalloc mappings
Date: Sun, 16 Aug 2020 19:08:56 +1000 [thread overview]
Message-ID: <20200816090904.83947-1-npiggin@gmail.com> (raw)
Let's try again.
Thanks,
Nick
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]
