[PATCH 1/2] mm: Move definition of MIN_MEMORY_BLOCK_SIZE to a header
From: Benjamin Herrenschmidt <benh@kernel.crashing.org>
Date: 2011-06-14 00:59:20
The macro MIN_MEMORY_BLOCK_SIZE is currently defined twice in two .c files, and I need it in a third one to fix a powerpc bug, so let's first move it into a header Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org> --- Ingo, Thomas: Who needs to ack the x86 bit ? I'd like to send that to Linus asap with the powerpc fix.
