fd27234f24 MIPS: SGI-IP30: Free some unused memory 
platform_device_add_data() duplicates the memory it is passed. So we can
free some memory to save a few bytes that would remain unused otherwise.

3ecc68349b memblock: rename memblock_free to memblock_phys_free 
Since memblock_free() operates on a physical range, make its name
reflect it and rename it to memblock_phys_free(), so it will be a
logical counterpart to memblock_phys_alloc().

The callers are updated with the below semantic patch:

    @@
    expression addr;
    expression size;
    @@
    - memblock_free(addr, size);
    + memblock_phys_free(addr, size);

0661cb2af0 mips: Bulk conversion to generic_handle_domain_irq() 
Wherever possible, replace constructs that match either
generic_handle_irq(irq_find_mapping()) or
generic_handle_irq(irq_linear_revmap()) to a single call to
generic_handle_domain_irq().

18ca45f5ba MIPS: Add missing linux/irqdomain.h includes 
A number of MIPS platforms are failing to directly include
irqdomain.h. Fix this so that we can drop unnecessary dependencies

Move HEART specific parts of mach-ip30/irq.h to asm/sgi/heart.h and IP30
specific parts to sgi-ip30/ip30-common.h.

26bff9eb49 MIPS: Only include the platform file needed 
Instead of including all Platform files, we simply include the
needed one and avoid clashes with makefile variables.
