Subject: [GIT PULL] x86/mm changes for v4.20
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: 977e4be5eb714c48a67afc26a6c477f24130a1f2 x86/stackprotector: Remove the call to boot_init_stack_canary() from cpu_startup_entry()
Lots of changes in this cycle:
- Lots of CPA optimizations and related cleanups (Thomas Gleixner, Peter Zijstra)
- Make lazy TLB mode even lazier (Rik van Riel)
- Fault handler cleanups and improvements (Dave Hansen)
- kdump, vmcore: Enable kdumping encrypted memory with AMD SME enabled
(Lianbo Jiang)
- Clean up VM layout documentation (Baoquan He, Ingo Molnar)
- ... plus misc other fixes and enhancements.
Thanks,
Ingo
