lib: vsprintf: optimised put_dec() for 32-bit machines

Those are not big functions though -- we are talking here about proposed function being below 512. It's a slippery slope. Here's where it ends: glibc has memcpy() function which is "on... 10 Aug 2010 00:28

[PATCH 22/43] memblock: Remove memblock_type.size and add memblock.memory_size instead
Right now, both the "memory" and "reserved" memblock_type structures have a "size" member. It represents the calculated memory size in the former case and is unused in the latter. This moves it out to the main memblock structure instead Signed-off-by: Benjamin Herrenschmidt <benh(a)kernel.crashing.org> --- arc... 6 Aug 2010 01:44

[PATCH 42/43] memblock: Option for the architecture to put memblock into the .init section
From: Yinghai Lu <yinghai(a)kernel.org> Arch code can define ARCH_DISCARD_MEMBLOCK in asm/memblock.h, which in turns causes memblock code and data to go respectively into the .init and .initdata sections. This will be used by the x86 architecture. If ARCH_DISCARD_MEMBLOCK is defined, the debugfs files to inspect... 6 Aug 2010 01:44

[PATCH 34/43] memblock: Separate memblock_alloc_nid() and memblock_alloc_try_nid()
The former is now strict, it will fail if it cannot honor the allocation within the node, while the later implements the previous semantic which falls back to allocating anywhere.

[PATCH 43/43] memblock: Add memblock_find_in_range()
From: Yinghai Lu <yinghai(a)kernel.org> This is a wrapper for memblock_find_base() using slightly different arguments (start,end instead of start,size for example) in order to make it easier to convert existing arch/x86 code.

[PATCH 28/43] memblock: split memblock_find_base() out of __memblock_alloc_base()
This will be used by the array resize code and might prove useful to some arch code as well at which point it can be made non-static.
