Re: [PATCH v2 0/7] MR5128: winevulkan: Use VK_EXT_map_memory_placed for memory mapping on wow64.

[Derek Lesho (＠dlesho)]

Not that it will likely come up, but as we're also allowing win32 clients to use this extension:
- Would it make sense to make sure incoming pPlacedAddress belongs to a NT mapping?
- Do we want to reset windows page protection back to '0' to match PROT_NONE resulting from VK_MEMORY_UNMAP_RESERVE_BIT_EXT?
