Merge branch 'master' into x86/memblock

Merge branch 'master' into x86/memblock

Conflicts & resolutions:

* arch/x86/xen/setup.c

	e668b99bd5 "xen: allow extra memory to be in multiple regions"
	f7f0a7a028 "memblock, x86: Replace memblock_x86_reserve/free..."

	conflicted on xen_add_extra_mem() updates.  The resolution is
	trivial as the latter just want to replace
	memblock_x86_reserve_range() with memblock_reserve().

* drivers/pci/intel-iommu.c

	f0b855d1f6b "x86/ia64: intel-iommu: move to drivers/iommu/"
	2410d4e78ec "bootmem: Replace work_with_active_regions() with..."

	conflicted as the former moved the file under drivers/iommu/.
	Resolved by applying the chnages from the latter on the moved
	file.

* mm/Kconfig

	ac0c6a4967e "memblock: add NO_BOOTMEM config symbol"
	5000c7e78c1 "memblock, x86: Make ARCH_DISCARD_MEMBLOCK a config option"

	conflicted trivially.  Both added config options.  Just
	letting both add their own options resolves the conflict.

* mm/memblock.c

	b100ee94d09 "mm/memblock.c: small function definition fixes"
	a9ce8aa68b4 "memblock: Remove memblock_memory_can_coalesce()"

	confliected.  The former updates function removed by the
	latter.  Resolution is trivial.
