Hi Greg,
When booting a 4.4.y stable-rc kernel with a fairly minimal config and CONFIG_KASAN=y and "nopti" on the kernel command line, or v4.4.109, I get a load of KASAN spews as below. A bisect takes me back to 85d3700c744a11 (x86/mm: If INVPCID is available, use it to flush global mappings), but I think the real fix is to also add 69e0210fd01ff15 (x86/kasan: Clear kasan_zero_page after TLB flush) onto your branch to address these false positives.
Again, nice find! I've queued this up as well, thanks.
