According to section "Canonicalization and Consistency Checks" in APM vol 2,
the following guest state is illegal:
"The MSR or IOIO intercept tables extend to a physical address that
is greater than or equal to the maximum supported physical address."
Patch# 1: Adds the KVM checks.
Patch# 2: Adds a test
Patch# 3: Replaces a hard-coded value with an available macro.
