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@xxxxxxxxxx/ ) 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 include/linux/kasan.h | 18 +++++++++++++++--- lib/Kconfig.kasan | 14 ++++++++++++++ mm/kasan/common.c | 4 ++++ mm/kasan/generic.c | 3 +++ mm/kasan/init.c | 6 +++--- mm/kasan/kasan.h | 4 ++++ mm/kasan/shadow.c | 8 ++++++++ 7 files changed, 51 insertions(+), 6 deletions(-) -- 2.30.2
