Subject: [PATCH v3 00/21] target-arm: Implement ARMv8.5-MemTag, user mode
Date: Fri, 15 Jan 2021 12:46:24 -1000 [thread overview]
Message-ID: <20210115224645.1196742-1-richard.henderson@linaro.org> (raw)
The kernel abi was finally merged into 5.10.
Changes for v3:
* Split out type changes to separate patches.
* Add doc comments; tweak alloc so that the !PAGE_VALID case is clear.
* Do not overlap PAGE_TARGET_2 with PAGE_RESERVED.
* Use syndrome.h, arm_deliver_fault.
