326	*
327	* This is VirtualBox's combined page table attributes. It combines regular page
328	* table and Intel EPT attributes. It's 64-bit in size so there's ample room for
329	* bits added in the future to EPT or regular page tables (for e.g. Protection Key).
330	*
331	* The following bits map 1:1 (shifted by PGM_PTATTRS_EPT_SHIFT) to the Intel EPT
332	* attributes as these are unique to EPT and fit within 64-bits despite the shift:
333	* - EPT_R : Read access.
334	* - EPT_W : Write access.
335	* - EPT_X_SUPER : Execute or execute for supervisor-mode linear addr access.
336	* - EPT_MEMTYPE : EPT memory type.
337	* - EPT_IGNORE_PAT: Ignore PAT memory type.
338	* - EPT_X_USER : Execute access for user-mode linear addresses.
339	*
340	* For regular page tables, the R bit is always 1 (same as P bit).
341	* For Intel EPT, the EPT_R and EPT_W bits are copied to R and W bits respectively.
342	*
343	* The following EPT attributes are mapped to the following positions because they
344	* exist in the regular page tables at these positions OR are exclusive to EPT and
345	* have been mapped to arbitrarily chosen positions:
346	* - EPT_A : Accessed (EPT bit 8 maps to bit 5).
347	* - EPT_D : Dirty (EPT bit 9 maps to bit 6).
348	* - EPT_SUPER_SHW_STACK : Supervisor Shadow Stack (EPT bit 60 maps to bit 24).
349	* - EPT_SUPPRESS_VE_XCPT: Suppress \#VE exception (EPT bit 63 maps to bit 25).
350	*
351	* Bits 12, 11:9 and 43 are deliberately kept unused (correspond to bit PS and bits
352	* 11:9 in the regular page-table structures and to bit 11 in the EPT structures
353	* respectively) as bit 12 is the page-size bit and bits 11:9 are reserved for
354	* use by software and we may want to use/preserve them in the future.
