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.
