    [PATCH] ppc64: Rewrite the openpic driver · 378193eb
    Benjamin Herrenschmidt authored
    This patch replaces the open_pic IRQ controller driver with a new
    version rewritten from scratch, called "mpic" (this is the name of
    IBM's open_pic implementation and also the only one actually used
    on any platform).
    
    It is smaller, hopefully more readable, supports the various variants
    of the cell in a single driver (open_pic_u3.c is gone), and adds
    optional support for the workaround of U3 mpic beeing used along with
    IO-APICs on HyperTransport (the eval board will uses that, among
    others).
