iLO5 will offer the same watchdog timer as previous generations, but the
PCI subsystem vendor ID will be PCI_VENDOR_ID_HP_3PAR (0x1590) instead of
PCI_VENDOR_ID_HP (0x103c).  Add 0x1590 to the whitelist and be more
specific when ignoring the 103c,1979 device.

Pull ARM fixes from Russell King:
 "Most of this update are fixes primarily discovered from testing on the
  older StrongARM 1110 and PXA systems, as a result of recent interest
  from several people in these platforms:

   - Locomo interrupt handling incorrectly stores the handler data in
     the chip's private data slot: when Locomo is combined with an
     interrupt controller who's chip uses the chip private data, this
     leads to an oops.

   - SA1111 was missing a call to clk_disable() to clean up after a
     failed probe.

   - SA1111 and PCMCIA suspend/resume was broken:

     The PCMCIA "ds" layer was using the legacy bus suspend/resume
     methods, which the core PM code is no longer calling as a result of
     device_pm_check_callbacks() introduced in commit aa8e54b5
     ("PM / sleep: Go direct_complete if driver has no callbacks").

     SA1111 was broken due to changes to PCMCIA which makes PCMCIA
     suspend itself later than the SA1111 code expects, and resume
     before the SA1111 code has initialised access to the pcmcia
     sub-device.

   - the default SA1111 interrupt mask polarity got messed up when it
     was converted to use a dynamic interrupt base number for its
     interrupts.

   - fix platform_get_irq() error code propagation, which was causing
     problems on platforms where the interrupt may not be available at
      probe time in DT setups.

   - fix the lack of clock to PCMCIA code on PXA platforms, which was
     omitted in conversions of PXA to CCF.

   - fix an oops in the PXA PCMCIA code caused by a previous commit not
     realising that Lubbock is different from the rest of the PXA PCMCIA
     drivers.

   - ensure that SA1111 low-level PCMCIA drivers propagate their error
     codes to the main probe function, rather than the driver silently
     accepting a failure.

   - fix the sa11xx debugfs reporting of timing information, which
     always indicated zero due to the clock being a factor of 1000 out.

   - fix the polarity of the status change signal reported from the
     sockets.

  Lastly, one ARM specific commit from Stefan Agner fixing the LPAE
  cache attributes"
