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.
Patch 1 is of RFC quality Patches 2-3 are independent and quite self-contained.
Sergey Dyasli (1): 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
