Subject: [PATCH 1/1 V2] clear leftmost bit when exit failure is vm entry type
Date: Mon, 19 Apr 2010 21:19:02 -0500	[thread overview]
Message-ID: <4BCD0F16.2080701@gmail.com> (raw)

hi,
 When the vm exit reason is VM Entry failures it has leftmost bit set.
 This patch
 - clears the leftmost bit when copying to vmx->exit_reason. This will make the checks like 
   if ((vmx->exit_reason == EXIT_REASON_MCE_DURING_VMENTRY) valid in vmx_complete_interrupts.
