Subject: memblock: fix memblock_is_region_memory()
From: Tomi Valkeinen <tomi.valkeinen@xxxxxxxxx>
memblock_is_region_memory() uses reserved memblocks to search for the
given region, while it should use the memory memblocks.
I encountered the problem with OMAP's framebuffer ram allocation.
Normally the ram is allocated dynamically, and this function is not
called. However, if we want to pass the framebuffer from the bootloader
to the kernel (to retain the boot image), this function is used to check
the validity of the kernel parameters for the framebuffer ram area.
