Subject: devm_memremap_release(): fix memremap'd addr handling

From: Toshi Kani <[email protected]>

commit 9273a8bbf58a15051e53a777389a502420ddc60e upstream.

The pmem driver calls devm_memremap() to map a persistent memory range. When the pmem driver is unloaded, this memremap'd range is not released so the kernel will leak a vma.

Fix devm_memremap_release() to handle a given memremap'd address properly.
