[PATCH 0/7] MR1339: ntdll: Support partially releasing virtual memory.

[Paul Gofman (＠gofman)]

The partial free is not supported from VirtualFree (we have a test for that) but NtFreeVirtualMemory supports it.

The primary motivation behind these patches is the preparation for VM placeholders support. With those flags (MEM_RESERVE_PLACEHOLDER, MEM_PRESERVE_PLACEHOLDER, MEM_REPLACE_PLACEHOLDER and MEM_COALESCE_PLACEHOLDERS) views might be arbitrary split or joined with just page alignment.
