Subject: [PATCH v13 0/3] KASAN core changes for ppc64 radix KASAN
Date:   Wed, 16 Jun 2021 18:02:41 +1000

Building on the work of Christophe, Aneesh and Balbir, I've ported
KASAN to 64-bit Book3S kernels running on the Radix MMU. I've been
trying this for a while, but we keep having collisions between the
kasan code in the mm tree and the code I want to put in to the ppc
tree.

So this series just contains the kasan core changes that we
need. These can go in via the mm tree. I will then propose the powerpc
changes for a later cycle. (The most recent RFC for the powerpc
changes is in the last series at
https://lore.kernel.org/linux-mm/20210615014705.2234866-1-dja@axtens.net/
)

v13 applies to next-20210611. There should be no noticeable changes to
other platforms.

Changes since v12: respond to Marco's review comments - clean up the
help for ARCH_DISABLE_KASAN_INLINE, and add an arch readiness check to
the new granule poisioning function. Thanks Marco.

Kind regards,
Daniel

Daniel Axtens (3):
  kasan: allow an architecture to disable inline instrumentation
  kasan: allow architectures to provide an outline readiness check
  kasan: define and use MAX_PTRS_PER_* for early shadow tables
