167	167	* Allocates non-contiguous page aligned physical memory without (necessarily) any kernel mapping.
168	168	*
169		* @returns IPRT status code.
	169	* This API is for allocating huge amounts of pages and will return
	170	* VERR_NOT_SUPPORTED if this cannot be implemented in a satisfactory
	171	* manner.
	172	*
	173	* @returns IPRT status code.
	174	* @retval VERR_NOT_SUPPORTED if it's not possible to allocated unmapped
	175	* physical memory on this platform. The caller should expect
	176	* this error and have a fallback strategy for it.
170	177	* @param pMemObj Where to store the ring-0 memory object handle.
171	178	* @param cb Number of bytes to allocate. This is rounded up to nearest page.
…	…
191	198	* Reserves kernel virtual address space.
192	199	*
	200	* If this function fails with VERR_NOT_SUPPORTED, the idea is that you
	201	* can use RTR0MemObjEnterPhys() + RTR0MemObjMapKernel() as a fallback if
	202	* you have a safe physical address range to make use of...
	203	*
193	204	* @returns IPRT status code.
194	205	* @param pMemObj Where to store the ring-0 memory object handle.
