Subject: [PATCH 00/14] KVM: arm64: SVE cleanups
Date: Fri, 12 Apr 2019 17:28:04 +0100	[thread overview]
Message-ID: <1555086498-26691-1-git-send-email-Dave.Martin@arm.com> (raw)

This series contains some cleanups applicable to the SVE KVM support
patches merged into kvmarm/next.  These arose from Andrew Jones'
review.

Apart from some minor changes to error codes and checking, these are
mostly cosmetic / sytlistic changes only.

Although straightforward, these changes have not been tested yet:
I'm posting them now so that reviewers can make a start on them.

The patches are based on
