      SuperH: Use HAVE_MEMBLOCK_NODE_MAP · 534cfbee
      由 Tejun Heo 提交于 
      sh doesn't access early_node_map[] directly and enabling
HAVE_MEMBLOCK_NODE_MAP is trivial - replacing add_active_range() calls
with memblock_set_node() and selecting HAVE_MEMBLOCK_NODE_MAP is
enough.

      memblock: s/memblock_analyze()/memblock_allow_resize()/ and update users · 1aadc056
      由 Tejun Heo 提交于 
      The only function of memblock_analyze() is now allowing resize of
memblock region arrays.  Rename it to memblock_allow_resize() and
update its users.

* The following users remain the same other than renaming.

  arm/mm/init.c::arm_memblock_init()
  microblaze/kernel/prom.c::early_init_devtree()
  powerpc/kernel/prom.c::early_init_devtree()
  openrisc/kernel/prom.c::early_init_devtree()
  sh/mm/init.c::paging_init()
  sparc/mm/init_64.c::paging_init()
  unicore32/mm/init.c::uc32_memblock_init()

* In the following users, analyze was used to update total size which
  is no longer necessary.

  powerpc/kernel/machine_kexec.c::reserve_crashkernel()
  powerpc/kernel/prom.c::early_init_devtree()
  powerpc/mm/init_32.c::MMU_init()
  powerpc/mm/tlb_nohash.c::__early_init_mmu()  
  powerpc/platforms/ps3/mm.c::ps3_mm_add_memory()
  powerpc/platforms/embedded6xx/wii.c::wii_memory_fixups()
  sh/kernel/machine_kexec.c::reserve_crashkernel()

* x86/kernel/e820.c::memblock_x86_fill() was directly setting
  memblock_can_resize before populating memblock and calling analyze
  afterwards.  Call memblock_allow_resize() before start populating.

memblock_can_resize is now static inside memblock.c.

      memblock: Kill memblock_init() · fe091c20
      由 Tejun Heo 提交于 
      memblock_init() initializes arrays for regions and memblock itself;
however, all these can be done with struct initializers and
memblock_init() can be removed.  This patch kills memblock_init() and
initializes memblock with struct initializer.

The only difference is that the first dummy entries don't have .nid
set to MAX_NUMNODES initially.  This doesn't cause any behavior
difference.

      memblock: Fix include breakages caused by 24aa0788 · 1c16d242
      由 Tejun Heo 提交于 
      24aa0788 (memblock, x86: Replace memblock_x86_reserve/free_range()
with generic ones) removed arch/x86/include/asm/memblock.h and dropped
its inclusion from include/linux/memblock.h which breaks other
architectures which depended on the generic memblock.h pulling in the
arch specific one.

However, the proper fix isn't adding back the asm inclusion.  memblock
doesn't have any arch dependent part and doesn't need arch specific
header file and asm/memblock.h files are either practically empty or
contain mostly unrelated arch specific stuff.

* In microblaze, sh, powerpc, sparc and openrisc, asm/memblock.h is
  either empty or just contains unused MEMBLOCK_DBG() macro.  Remove
  them.

* In arm and unicore32, asm/memblock.h contains arch specific stuff.
  Include it directly from its users.  It might be a good idea to
  rename the header file to avoid confusion.

      cpuidle: stop depending on pm_idle · a0bfa137
      由 Len Brown 提交于 
      cpuidle users should call cpuidle_call_idle() directly
rather than via (pm_idle)() function pointer.

Architecture may choose to continue using (pm_idle)(),
but cpuidle need not depend on it:

  my_arch_cpu_idle()
	...
	if(cpuidle_call_idle())
		pm_idle();
