Subject: [PATCH v2 0/3] ARM: Support KFENCE feature
Date: Wed, 3 Nov 2021 21:38:42 +0800 [thread overview]
Message-ID: <20211103133845.78528-1-wangkefeng.wang@huawei.com> (raw)
This patchset supports Kfence feature, tested the kfence_test on ARM QEMU
with or without ARM_LPAE and all passed.
V2:
- drop patch4 in v1, which is used a new way to skip kfence test
see commit c40c6e593bf9 ("kfence: test: fail fast if disabled at boot")
- fix some issue about NO MMU
- drop useless set_memory_valid() under no mmu
- fix implicit declaration of function ‘is_write_fault’ if no mmu
- make KFENCE depends on !XIP_KERNEL, no tested with xip
v1:
