Greg Ungerer f9a7febd82 MIPS: Fix start of free memory when using initrd 
Currently when using an initrd on a MIPS system the start of the bootmem
region of memory is set to the larger of the end of the kernel bss region
(_end) or the end of the initrd. In a typical memory layout where the
initrd is at some address above the kernel image this means that the start
of the bootmem region will be the end of the initrd. But when we are done
processing/loading the initrd we have no way to reclaim the memory region
it occupied, and we lose a large chunk of now otherwise empty RAM from our
final running system.

The bootmem code is designed to allow this initrd to be reserved (and the
code in finalize_initrd() currently does this). When the initrd is finally
processed/loaded its reserved memory is freed.

Fix the setting of the start of the bootmem map to be the end of the kernel.

[ralf@linux-mips.org: fold in the fix of Ashok Kumar <ashoks@broadcom.com>.]
