Subject: [PATCH 09/10] KVM: Update intr delivery func to accept unsigned long* bitmap
Date: Wed,  7 Jan 2009 18:42:45 +0800	[thread overview]
Message-ID: <1231324966-22286-10-git-send-email-sheng@linux.intel.com> (raw)
In-Reply-To: <1231324966-22286-1-git-send-email-sheng@linux.intel.com>

Would be used with bit ops, and would be easily extended if KVM_MAX_VCPUS is
increased.
