Subject: [PATCH 0/4] powerpc/64s: Enable KFENCE
Date: Mon, 17 May 2021 16:16:54 +1000 [thread overview]
Message-ID: <20210517061658.194708-1-jniethe5@gmail.com> (raw)
This adds support for radix to Christophe's series that enabled KFENCE on
powerpc/64s/hash:
https://lore.kernel.org/linuxppc-dev/8dfe1bd2abde26337c1d8c1ad0acfcc82185e0d5.1614868445.git.christophe.leroy@csgroup.eu/
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
