KVM: x86: do mask out upper bits of PAE CR3
This reverts the change of commit f85c758dbee54cc3612a6e873ef7cecdb66ebee5,
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.
