[PATCH 0/4] powerpc/64s: Enable KFENCE

[Jordan Niethe]

This adds support for radix to Christophe's series that enabled KFENCE on
powerpc/64s/hash:

First implement DEBUG_PAGEALLOC for radix so KFENCE can reuse the same
infrastructure. 

This requires the "powerpc: Further Strict RWX support" series:

Christophe Leroy (3):
  powerpc/64s: Remove unneeded #ifdef CONFIG_DEBUG_PAGEALLOC in
    hash_utils
  powerpc/64s: Allow double call of kernel_[un]map_linear_page()
  powerpc: Enable KFENCE on BOOK3S/64
