Subject: linux-next: powerpcle qemu boot failure after merge of the akpm
 tree

Hi all,

[I am guessing that is is something in Andrew's tree that has caused
this.]

My qemu boot of the powerpc pseries_le_defconfig config failed like this:

htab_hash_mask    = 0x1ffff
-----------------------------------------------------
numa:   NODE_DATA [mem 0x7ffe7000-0x7ffebfff]
Kernel panic - not syncing: sparse_buffer_init: Failed to allocate 2147483648 bytes align=0x10000 nid=0 from=fffffffffffffff
