Subject: [PATCH v2 2/3] entry: KVM: Allow use of generic KVM entry w/o full generic support
Date: Thu, 29 Jul 2021 22:09:15 +0000 [thread overview]
Message-ID: <20210729220916.1672875-3-oupton@google.com> (raw)
In-Reply-To: <20210729220916.1672875-1-oupton@google.com>
Some architectures (e.g. arm64) have yet to adopt the generic entry
infrastructure. Despite that, it would be nice to use some common
plumbing for guest entry/exit handling. For example, KVM/arm64 currently
does not handle TIF_NOTIFY_PENDING correctly.
Allow use of only the generic KVM entry code by tightening up the
include list. No functional change intended.
