[PATCH 18/43] memblock: Introduce default allocation limit and use it to replace explicit ones
This introduce memblock.current_limit which is used to limit allocations from memblock_alloc() or memblock_alloc_base(..., MEMBLOCK_ALLOC_ACCESSIBLE). The old MEMBLOCK_ALLOC_ANYWHERE changes value from 0 to ~(u64)0 and can still be used with memblock_alloc_base() to allocate really anywhere. It is -no-longer- c... 6 Aug 2010 01:44

[PATCH 05/43] memblock/arm: pfn_valid uses memblock_is_memory()
The implementation is pretty much similar. There is a -small- added overhead by having another function call and the address shift. If that becomes a concern, I suppose we could actually have memblock itself expose a memblock_pfn_valid() which then ARM can use directly with an appropriate #define...

[PATCH 19/43] memblock: Remove rmo_size, burry it in arch/powerpc where it belongs
The RMA (RMO is a misnomer) is a concept specific to ppc64 (in fact server ppc64 though I hijack it on embedded ppc64 for similar purposes) and represents the area of memory that can be accessed in real mode (aka with MMU off), or on embedded, from the exception vectors (which is bolted in the TLB) which pretty muc... 6 Aug 2010 01:44

[PATCH 35/43] memblock: Make memblock_alloc_try_nid() fallback to MEMBLOCK_ALLOC_ANYWHERE
memblock_alloc_nid() used to fallback to allocating anywhere by using memblock_alloc() as a fallback. However, some of my previous patches limit memblock_alloc() to the region covered by MEMBLOCK_ALLOC_ACCESSIBLE which is not quite what we want for memblock_alloc_try_nid(). So we fix it by explicitely using ME... 6 Aug 2010 01:44
