[PATCH 14/33] KVM: VMX: Add printk_ratelimit in vmx_intr_assist

From: Avi Kivity
Date: Sun Jan 06 2008 - 09:43:56 EST


From: Ryan Harper <ryanh@xxxxxxxxxx>

Add printk_ratelimit check in front of printk. This prevents spamming
of the message during 32-bit ubuntu 6.06server install. Previously, it
would hang during the partition formatting stage.
