[PATCH v2 00/13] arm gicv3 ITS: Various bug fixes and refactorings


From: Peter Maydell
Subject: [PATCH v2 00/13] arm gicv3 ITS: Various bug fixes and refactorings
Date: Tue, 11 Jan 2022 17:10:35 +0000

I've been working on the ITS to add support for the GICv4 functionality.
In the course of that I found a handful of bugs in it and also some
places where the code benefited from refactoring to make it a better
base to put in the GICv4 parts. This patchset is just the bugfixes
and cleanups, because there are enough patches here that I figured it
made sense to send them out now rather than holding on to them.

Most of these patches were in v1 and have been reviewed already.

Changes from v1:
 * first half of the series is now upstream
 * patch 1 now has the '1ULL' and uint64_t fixes that were
   partly split across two patches in the old series and partly missing
 * new patches 12 and 13

NB: I left the returns of -1 in patch 11.

Patches still needing review: 1, 12, 13

thanks
