memblock updates
Hi folks ! Here's my current branch. This time build tested on sparc(64), arm, powerpc and sh. I don't have a microblaze compiler at hand. Not much difference from the previous one. Off the top of my head: - Added the memblock_is_region_reserved() fix at the beginning (I'll send that to Linus separately ... 6 Aug 2010 01:44

[PATCH 31/43] memblock: Add arch function to control coalescing of memblock memory regions
Some archs such as ARM want to avoid coalescing accross things such as the lowmem/highmem boundary or similar. This provides the option to control it via an arch callback for which a weak default is provided which always allows coalescing.

[PATCH 04/43] memblock: Implement memblock_is_memory and memblock_is_region_memory
To make it fast, we steal ARM's binary search for memblock_is_memory() and we use that to also the replace existing implementation of memblock_is_reserved().

[PATCH 23/43] memblock: Move memblock arrays to static storage in memblock.c and make their size a variable
This is in preparation for having resizable arrays. Note that we still allocate one more than needed, this is unchanged from the previous implementation.

[PATCH 30/43] memblock: Add array resizing support
When one of the array gets full, we resize it. After much thinking and a few iterations of that code, I went back to on-demand resizing using the (new) internal memblock_find_base() function, which is pretty much what Yinghai initially proposed, though there some differences in the details. To work this relies on... 6 Aug 2010 01:44
