Hi. I'm afraid this doesn't compile:
/home/petmay01/linaro/qemu-for-merges/hw/misc/mips_cmgcr.c: In
function ‘mips_gcr_init’:
/home/petmay01/linaro/qemu-for-merges/hw/misc/mips_cmgcr.c:107:31:

                              &error_abort);

(and similar other errors).

I think you've unfortunately collided with a patch in Paolo's
recent pull request which changes how we handle qapi/error.h
(it's no longer pulled in by osdep.h by default); see commit
da34e65cb.
