Merge branch 'x86-pmem-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull PMEM driver from Ingo Molnar: "This is the initial support for the pmem block device driver: persistent non-volatile memory space mapped into the system's physical memory space as large physical memory regions. The driver is based on Intel code, written by Ross Zwisler, with fixes by Boaz Harrosh, integrated with x86 e820 memory resource management and tidied up by Christoph Hellwig. Note that there were two other separate pmem driver submissions to lkml: but apparently all parties (Ross Zwisler, Boaz Harrosh) are reasonably happy with this initial version. This version enables minimal support that enables persistent memory devices out in the wild to work as block devices, identified through a magic (non-standard) e820 flag and auto-discovered if CONFIG_X86_PMEM_LEGACY=y, or added explicitly through manipulating the memory maps via the "memmap=..." boot option with the new, special '!' modifier character. Limitations: this is a regular block device, and since the pmem areas are not struct page backed, they are invisible to the rest of the system (other than the block IO device), so direct IO to/from pmem areas, direct mmap() or XIP is not possible yet. The page cache will also shadow and double buffer pmem contents, etc. Initial support is for x86" * 'x86-pmem-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: drivers/block/pmem: Fix 32-bit build warning in pmem_alloc() drivers/block/pmem: Add a driver for persistent memory x86/mm: Add support for the non-standard protected e820 type
