[PATCH 17/31] memblock: split memblock_find_base() out of __memblock_alloc_base()
From: Benjamin Herrenschmidt <benh(a)kernel.crashing.org> 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. Also add comment as to why aligning size is important [ Yinghai Lu ]: it should return MEMBLOCK_ERROR when it fail to fi... 22 Jul 2010 14:43

[PATCH 14/31] memblock: Make memblock_find_region() out of memblock_alloc_region()
From: Benjamin Herrenschmidt <benh(a)kernel.crashing.org> This function will be used to locate a free area to put the new memblock arrays when attempting to resize them. memblock_alloc_region() is gone, the two callsites now call memblock_add_region().

[PATCH 08/31] memblock: Remove rmo_size, burry it in arch/powerpc where it belongs
From: Benjamin Herrenschmidt <benh(a)kernel.crashing.org> 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 excep... 22 Jul 2010 14:43

[PATCH 09/31] memblock: Change u64 to phys_addr_t
From: Benjamin Herrenschmidt <benh(a)kernel.crashing.org> Let's not waste space and cycles on archs that don't support >32-bit physical address space.

[PATCH] cgroupfs: create /sys/fs/cgroup to mount cgroupfs on
We really shouldn't be asking userspace to create new root filesystems. So follow along with all of the other in-kernel filesystems, and provide a mount point in sysfs. For cgroupfs, this should be in /sys/fs/cgroup/ This change provides that mount point when the cgroup filesystem is registered in the kernel. ... 22 Jul 2010 14:43

[PATCH 23/31] memblock: Separate memblock_alloc_nid() and memblock_alloc_try_nid()
From: Benjamin Herrenschmidt <benh(a)kernel.crashing.org> 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.
