+Subject: arch/x86/kvm/mmu.c: work around gcc-4.4.4 bug
+
+From: Andrew Morton <akpm@linux-foundation.org>
+
+commit 5ec45a192fe6e287f0fc06d5ca4f3bd446d94803 upstream.
+
+Fix this compile issue with gcc-4.4.4:
+
+   arch/x86/kvm/mmu.c: In function 'kvm_mmu_pte_write':
+   arch/x86/kvm/mmu.c:4256: error: unknown field 'cr0_wp' specified in initializer
+   arch/x86/kvm/mmu.c:4257: error: unknown field 'cr4_pae' specified in initializer
+   arch/x86/kvm/mmu.c:4257: warning: excess elements in union initializer
+   ...
+
+gcc-4.4.4 (at least) has issues when using anonymous unions in
+initializers.
+
+Fixes: edc90b7dc4ceef6 ("KVM: MMU: fix SMAP virtualization")
