      parisc: KittyHawk LCD fix · 79a04296
      Guy Martin authored
      
      
      K class aka KittyHawk don't have LED support on their LCD. Installing
      HP-UX confirmed this. The current led_wq fills the LCD with black
      characters each time it runs.
      
      The patch prevents the led_wq workqueue and its proc entry to be
      created for KittyHawk machines.
      
      It also increase min_cmd_delay as currently, one character out of two
      is lost when a string is sent to the LCD.

      parisc: convert the rest of the irq handlers to simple/percpu · 51890613
      James Bottomley authored
      
      
      The generic conversion eliminates the spurious no_ack and no_end
      routines, converts all the cascaded handlers to handle_simple_irq() and
      makes iosapic use a modified handle_percpu_irq() to become the same as
      the CPU irq's.  This isn't an essential change, but it eliminates the
      mask/unmask overhead of handle_level_irq().

      parisc: fix dino/gsc interrupts · d16cd297
      James Bottomley authored
      
      
      The essential problem we're currently having is that dino (and gsc) is a
      cascaded CPU interrupt.  Under the old __do_IRQ() handler, our CPU
      interrupts basically did an ack followed by an end.  In the new scheme,
      we replaced them with level handlers which do a mask, an ack and then an
      unmask (but no end).  Instead, with the renaming of end to eoi, we
      actually want to call the percpu flow handlers, because they actually
      have all the characteristics we want.
      
      This patch does the conversion and gets my C360 booting again.

      annotation, and mark any functions it calls as notrace

      The existing code invokes the syscall with rubbish in r7,
      due to what looks like an incorrect literal load idiom.
