Subject: [GIT PULL] x86/mm changes for v4.12
Linus,
Please pull the latest x86-mm-for-linus git tree from:
git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip.git x86-mm-for-linus
# HEAD: 71389703839ebe9cb426c72d5f0bd549592e583c mm, zone_device: Replace {get, put}_zone_device_page() with a single reference to fix pmem crash
NOTE: due to a very busy cycle within the x86 tree, this tree grew a number of
dependencies and thus depends on you having pulled the following v4.12 trees:
x86-process-for-linus
x86-cpu-for-linus
x86-boot-for-linus
If you did not pull some of those trees then please disregard this pull request,
I'll rework it all!
The main x86 MM changes in this cycle were:
- Continued native kernel PCID support preparation patches to the TLB flushing
code (Andy Lutomirski)
- Various fixes related to 32-bit compat syscall returning address over 4Gb in
applications, launched from 64-bit binaries - motivated by C/R frameworks such
as Virtuozzo. (Dmitry Safonov)
- Continued Intel 5-level paging enablement: in particular the conversion
of x86 GUP to the generic GUP code. (Kirill A. Shutemov)
- x86/mpx ABI corner case fixes/enhancements (Joerg Roedel)
- ... plus misc updates, fixes and cleanups.
I'd like to draw special attention to this late MM commit:
71389703839e: mm, zone_device: Replace {get, put}_zone_device_page() with a single reference to fix pmem crash
... which is a late fix, and which I believe is the right thing to do - but please
double check.
Thanks,
Ingo
