    x86/uv: Use hierarchical irqdomain to manage UV interrupts · 43fe1abc
    Jiang Liu authored
    Enhance UV code to support hierarchical irqdomain, it helps to make
    the architecture more clear.
    
    We construct hwirq based on mmr_blade and mmr_offset, but mmr_offset
    has type unsigned long, it may exceed the range of irq_hw_number_t. So
    help about the way to construct hwirq based on mmr_blade and
    mmr_offset is welcomed!
    
    Folded a patch from Dimitri Sivanich <sivanich@sgi.com> to fix a bug
    on UV platforms, please refer to:
