    KVM: x86: do mask out upper bits of PAE CR3 · a512177e
    Paolo Bonzini authored
    This reverts the change of commit f85c758d,
    as the behavior it modified was intended.
    
    The VM is running in 32-bit PAE mode, and Table 4-7 of the Intel manual
    says:
    
    Table 4-7. Use of CR3 with PAE Paging
    Bit Position(s)	Contents
    4:0		Ignored
    31:5		Physical address of the 32-Byte aligned
    		page-directory-pointer table used for linear-address
    		translation
    63:32		Ignored (these bits exist only on processors supporting
    		the Intel-64 architecture)
    
    To placate the static checker, write the mask explicitly as an
    unsigned long constant instead of using a 32-bit unsigned constant.
