444d084b46 KVM: selftests: Unconditionally allocate EPT tables in memslot 0
Drop the EPTP memslot param from all EPT helpers and shove the hardcoded
'0' down to the vm_phy_page_alloc() calls.

No functional change intended.

150a282d43 KVM: selftests: Move APIC definitions into a separate file
Processor.h is a hodgepodge of definitions. Though the local APIC is
technically built into the CPU these days, move the APIC definitions
into a new header file: apic.h.

7a873e4555 KVM: selftests: Verify supported CR4 bits can be set before KVM_SET_CPUID2
Extend the KVM_SET_SREGS test to verify that all supported CR4 bits, as
enumerated by KVM, can be set before KVM_SET_CPUID2, i.e. without first
defining the vCPU model.  KVM is supposed to skip guest CPUID checks
when host userspace is stuffing guest state.

Check the inverse as well, i.e. that KVM rejects KVM_SET_REGS if CR4
has one or more unsupported bits set.

97a71a5455 KVM: selftests: test behavior of unmapped L2 APIC-access address
Add a regression test for commit 671ddc700f ("KVM: nVMX: Don't leak
L1 MMIO regions to L2").

First, check to see that an L2 guest can be launched with a valid
APIC-access address that is backed by a page of L1 physical memory.

Next, set the APIC-access address to a (valid) L1 physical address
that is not backed by memory. KVM can't handle this situation, so
resuming L2 should result in a KVM exit for internal error
(emulation).

Rename SECONDARY_EXEC_RDTSCP to SECONDARY_EXEC_ENABLE_RDTSCP in
preparation for consolidating the logic for adjusting secondary exec
