Expand description

Allocate virtually contiguous kernel memory backed by fragmented physical pages.

This is the explicit large-allocation API for kernel callers that require a large virtually contiguous range but not physical contiguity.

Returned pointers are aligned to a 4 KiB page boundary. For alignment stricter than one page, do not route through [GlobalAlloc] / large [Layout] on this heap : use a dedicated aligned mapping or slab path.
