Xiao Guangrong dd180b3e90 KVM: VMX: fix tlb flush with invalid root ... Commit 341d9b535b6c simplify reload logic while entry guest mode, it can avoid unnecessary sync-root if KVM_REQ_MMU_RELOAD and KVM_REQ_MMU_SYNC both set. But, it cause a issue that when we handle 'KVM_REQ_TLB_FLUSH', the root is invalid, it is triggered during my test: Kernel BUG at ffffffffa00212b8 [verbose debug info unavailable] ...... Fixed by directly return if the root is not ready. Signed-off-by: Xiao Guangrong <xiaoguangrong@cn.fujitsu.com> Signed-off-by: Marcelo Tosatti <mtosatti@redhat.com>		2010-08-02 06:40:16 +03:00
