Sean Christopherson 3bae0459bc KVM: x86/mmu: Drop KVM's hugepage enums in favor of the kernel's enums
Replace KVM's PT_PAGE_TABLE_LEVEL, PT_DIRECTORY_LEVEL and PT_PDPE_LEVEL
with the kernel's PG_LEVEL_4K, PG_LEVEL_2M and PG_LEVEL_1G.  KVM's
enums are borderline impossible to remember and result in code that is
visually difficult to audit, e.g.

        if (!enable_ept)
                ept_lpage_level = 0;
        else if (cpu_has_vmx_ept_1g_page())
                ept_lpage_level = PT_PDPE_LEVEL;
        else if (cpu_has_vmx_ept_2m_page())
                ept_lpage_level = PT_DIRECTORY_LEVEL;
        else
                ept_lpage_level = PT_PAGE_TABLE_LEVEL;

versus

        if (!enable_ept)
                ept_lpage_level = 0;
        else if (cpu_has_vmx_ept_1g_page())
                ept_lpage_level = PG_LEVEL_1G;
        else if (cpu_has_vmx_ept_2m_page())
                ept_lpage_level = PG_LEVEL_2M;
        else
                ept_lpage_level = PG_LEVEL_4K;

No functional change intended.
