Subject: [PATCH v1 0/4] basic KASAN support for Xen PV domains

This series allows to boot and run Xen PV kernels (Dom0 and DomU) with
CONFIG_KASAN=y. It has been used internally for some time now with good
results for finding memory corruption issues in Dom0 kernel.

Only Outline instrumentation is supported at the moment.

Sergey Dyasli (2):
  kasan: introduce set_pmd_early_shadow()
  x86/xen: add basic KASAN support for PV kernel

Ross Lagerwall (2):
  xen: teach KASAN about grant tables
  xen/netback: Fix grant copy across page boundary with KASAN
