rGfe05296fc3d0: arm64: Add pmap integration for KMSAN
Summary
  • In pmap_bootstrap_san(), allocate the root PTPs for the shadow maps. (For KASAN, this is done earlier since we need to do some special bootstrapping for the kernel stack.)
  • Adjust ifdefs to include KMSAN.
  • Expand the shadow maps when pmap_growkernel() is called.
