From d40a1ee4859c673677c9811ae84475c4051baca5 Mon Sep 17 00:00:00 2001 From: Sheng Yang Date: Mon, 1 Sep 2008 19:41:20 +0800 Subject: KVM: MMU: Modify kvm_shadow_walk.entry to accept u64 addr EPT is 4 level by default in 32pae(48 bits), but the addr parameter of kvm_shadow_walk->entry() only accept unsigned long as virtual address, which is 32bit in 32pae. This result in SHADOW_PT_INDEX() overflow when try to fetch level 4 index. Fix it by extend kvm_shadow_walk->entry() to accept 64bit addr in parameter.
