Subject: [PATCH v3 00/10] Rework hyp vector handling
Date: Fri, 13 Nov 2020 11:38:37 +0000 [thread overview]
Message-ID: <20201113113847.21619-1-will@kernel.org> (raw)
Hi all,
This is version three of the patches I previously posted here:
v1: https://lore.kernel.org/r/20201026155833.24847-1-will@kernel.org
v2: https://lore.kernel.org/r/20201109214726.15276-1-will@kernel.org
Changes since v3 include:
* Fix vector initialisation for VHE systems
* Remove redundant hyp vectors entry
Hopefully this survives more testing than the last lot.
Cheers,
Will
