Merge branch 'master' into for-next
Sync with Linus tree to have 157550ff ("mtd: add GPMI-NAND driver in the config and Makefile") as I have patch depending on that one.

2265 MIPS R10000 does support a 44 bit / 16TB address space as opposed to
2266 previous 64-bit processors which only supported 40 bit / 1TB. If you
2267 need processes of more than 1TB virtual address space, say Y here.
2268 This will result in additional memory usage, so it is not
2269 recommended for normal users.
