 *	Allocate new VM region anywhere it would fit in the address space.
 *
 * VM_FLAGS_PURGABLE
 *	Create a purgable VM object for that new VM region.

 * VM_FLAGS_4GB_CHUNK
 *	The new VM region will be chunked up into 4GB sized pieces.
 *
 * VM_FLAGS_NO_PMAP_CHECK
 *	(for DEBUG kernel config only, ignored for other configs)
 *	Do not check that there is no stale pmap mapping for the new VM region.
 *	This is useful for kernel memory allocations at bootstrap when building

 * VM_FLAGS_OVERWRITE
 *	The new VM region can replace existing VM regions if necessary

 *
 * VM_FLAGS_NO_CACHE
 *	Pages brought in to this VM region are placed on the speculative
 *	queue instead of the active queue.  In other words, they are not
 *	cached so that they will be stolen first if memory runs low.
 *
 * VM_FLAGS_GUARD_OBJECT_OPTOUT
 *	Opt out this allocation from the guard object allocation policy.
