- This API provides a method for a CPU to allocate a specific region for\r
- storing page tables.\r
-\r
- This API can be called more once to allocate memory for page tables.\r
-\r
- Allocates the number of 4KB pages of type EfiRuntimeServicesData and returns\r
- a pointer to the allocated buffer. The buffer returned is aligned on a 4KB\r
- boundary. If Pages is 0, then NULL is returned. If there is not enough\r
- memory remaining to satisfy the request, then NULL is returned.\r
-\r
- This function can also return NULL if there is no preference on where the\r
- page tables are allocated in SMRAM.\r
-\r
- @param Pages The number of 4 KB pages to allocate.\r
-\r
- @return A pointer to the allocated buffer for page tables.\r
- @retval NULL Fail to allocate a specific region for storing page tables,\r
- Or there is no preference on where the page tables are\r
