memblock: s/memblock_analyze()/memblock_allow_resize()/ and update users
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.
