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.

Linux kernel ============ There are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. Please read Documentation/admin-guide/README.rst first. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. The formatted documentation can also be read online at: https://www.kernel.org/doc/html/latest/ There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
