Subject: [PATCH 2/3] arm32: kvm: rename CONFIG_KVM_ARM_MAX_VCPUS
Date: Sat, 14 Sep 2013 14:10:55 +0200 [thread overview]
Message-ID: <1379160656-28050-3-git-send-email-drjones@redhat.com> (raw)
In-Reply-To: <1379160656-28050-1-git-send-email-drjones@redhat.com>
Drop the _ARM_ part of the name. We can then introduce a config option
like this to aarch64 and other arches using the same name - allowing
grep to show them all. Also update the help text to describe the option
more completely.

Static number of max supported virtual CPUs per VM.
