Re: [PATCH fixes 1/3] MIPS: Loongson64: Reserve vgabios memory on boot

vgabios is passed from firmware to kernel on Loongson64 systems. Sane firmware will keep this pointer in reserved memory space passed from the firmware but insane firmware keeps it in low memory before kernel entry that is not reserved.

Previously kernel won't try to allocate memory from low memory before kernel entry on boot, but after converting to memblock it will do that.

Fix by resversing those memory on early boot.

Reserving? :-)
