[PATCH 1/1 V2] clear leftmost bit when exit failure is vm entry type

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



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.
