Subject[PATCH v2 0/5] x86/kasan: Bug fixes for recent CEA changes
From
Three fixes for the recent changes to how KASAN populates shadows for
the per-CPU portion of the CPU entry areas. The v1 versions were posted
independently as I kept root causing issues after posting individual fixes.

v2:
- Map the entire per-CPU area in one shot. [Andrey]
- Use the "early", i.e. read-only, variant to populate the shadow for
the shared portion (read-only IDT mapping) of the CEA. [Andrey]

v1:

- https://lore.kernel.org/all/20221104220053.1702977-1-seanjc@google.com
- https://lore.kernel.org/all/20221104183247.834988-1-seanjc@google.com

Sean Christopherson (5):
x86/mm: Recompute physical address for every page of per-CPU CEA
mapping
x86/mm: Populate KASAN shadow for entire per-CPU range of CPU entry
area
x86/kasan: Rename local CPU_ENTRY_AREA variables to shorten names
x86/kasan: Add helpers to align shadow addresses up and down
x86/kasan: Populate shadow for shared chunk of the CPU entry area
