[PATCH V2 00/15] genirq endian fixes; bcm7120/brcmstb IRQ updates

[Kevin Cernekee]

I don't know if this will make everyone 100% happy but hopefully we're
inching slightly closer to a solution...

V1->V2:

 - Rework big endian support per the discussion on the list
 - Get rid of the global compile-time irq_reg_{readl,writel} accessors
   and make them private to generic-chip.c, so that on multiplatform
   kernels, different irqchip drivers can specify different MMIO behavior
 - Rebase on Linus's head of tree

Patch 06/15 still feels a bit like premature optimization to me.  Perhaps
we can drop it if nobody reports a measurable performance advantage in
any known configuration?


Kevin Cernekee (15):
  irqchip: Replace irq_reg_{readl,writel} with {readl,writel}
  sh: Eliminate unused irq_reg_{readl,writel} accessors
  genirq: Generic chip: Move irq_reg_{readl,writel} accessors into
    generic-chip.c
  genirq: Generic chip: Change irq_reg_{readl,writel} arguments
  genirq: Generic chip: Add big endian I/O accessors
  genirq: Generic chip: Optimize for fixed-endian systems
  irqchip: brcmstb-l2: Eliminate dependency on ARM code
  irqchip: bcm7120-l2: Eliminate bad IRQ check
  irqchip: Remove ARM dependency for bcm7120-l2 and brcmstb-l2
  irqchip: bcm7120-l2: Make sure all register accesses use base+offset
  irqchip: bcm7120-l2: Fix missing nibble in gc->unused mask
  irqchip: bcm7120-l2: Use gc->mask_cache to simplify suspend/resume
    functions
  irqchip: bcm7120-l2: Extend driver to support 64+ bit controllers
  irqchip: Decouple bcm7120-l2 from brcmstb-l2
  irqchip: bcm7120-l2: Enable big endian register accesses on BE kernels
