Subject: [GIT PULL] x86/mm changes for v4.13
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# HEAD: 8781fb7e9749da424e01daacd14834b674658c63 x86/mm: Delete a big outdated comment about TLB flushing
The main changes in this cycle were:
- Continued work to add support for 5-level paging provided by future Intel CPUs.
In particular we switch the x86 GUP code to the generic implementation.
(Kirill A. Shutemov)
- Continued work to add PCID CPU support to native kernels as well. In this round
most of the focus is on reworking/refreshing the TLB flush infrastructure for
the upcoming PCID changes. (Andy Lutomirski)
