Binbin Wu bede6eb4db KVM: x86: Use boolean return value for is_{pae,pse,paging}()
Convert is_{pae,pse,paging}() to use kvm_is_cr{0,4}_bit_set() and return
bools.  Returning an "int" requires not one, but two implicit casts, first
from "unsigned long" to "int", and then again to a "bool".  Both casts are
more than a bit dangerous; the ulong=>int casts would drop a bit on 64-bit
kernels _if_ the bits in question weren't in the lower 32 bits, and the
int=>bool cast can result in false negatives/positives, e.g. see commit
0c928ff26b ("KVM: SVM: Fix benign "bool vs. int" comparison in
svm_set_cr0()").
