powerpc: make of_device_ids const of_device_ids (i.e. compatible strings and the respective data) are not supposed to change at runtime. All functions working with of_device_ids provided by <linux/of.h> work with const of_device_ids. This allows to mark all struct of_device_id const, too. While touching these line also put the __init annotation at the right position where necessary.

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.

powerpc: Cleanup memblock usage * early_init_devtree(): Total memory size is aligned to PAGE_SIZE; however, alignment isn't enforced if memory_limit is explicitly specified. Simplify the logic and always apply PAGE_SIZE alignment. * MMU_init(): memblock regions is truncated by directly modifying memblock.memory.cnt. This is incomplete (reserved array is not truncated) and unnecessarily low level hindering further memblock improvments. Use memblock_enforce_memory_limit() instead. * wii_memory_fixups(): Unnecessarily low level direct manipulation of memblock regions. The same result can be achieved using properly abstracted operations. Reimplement using memblock API.

powerpc: wii: allow ioremap within the memory hole Enable the flag that allows a platform to ioremap memory marked as reserved. This is currently needed on the Nintendo Wii video game console due to the workaround introduced in "wii: use both mem1 and mem2 as ram". This will no longer be needed when proper discontig memory support for 32-bit PowerPC is added to the kernel.

wii: use both mem1 and mem2 as ram The Nintendo Wii video game console has two discontiguous RAM regions: - MEM1: 24MB @ 0x00000000 - MEM2: 64MB @ 0x10000000 Unfortunately, the kernel currently does not support discontiguous RAM memory regions on 32-bit PowerPC platforms. This patch adds a series of workarounds to allow the use of the second memory region (MEM2) as RAM by the kernel. Basically, a single range of memory from the beginning of MEM1 to the end of MEM2 is reported to the kernel, and a memory reservation is created for the hole between MEM1 and MEM2. With this patch the system is able to use all the available RAM and not just ~27% of it. This will no longer be needed when proper discontig memory support for 32-bit PowerPC is added to the kernel.
