- * Only EPT supported for now; otherwise, one would need to
- * find out efficiently whether the guest page tables are
- * also using huge pages.
+ * We can not do huge page mapping for the indirect shadow
+ * page (sp) found on the last rmap (level = 1 ) since
+ * indirect sp is synced with the page table in guest and
+ * indirect sp->level = 1 means the guest page table is
+ * using 4K page size mapping.
+ * We cannot do huge page mapping for indirect shadow pages,
+ * which are found on the last rmap (level = 1) when not using
+ * tdp; such shadow pages are synced with the page table in
+ * the guest, and the guest page table is using 4K page size
+ * mapping if the indirect sp has level = 1.
