Pull ACPI power management fix from Rafael Wysocki:
 "This is just a one-liner fixing a regression introduced in 3.13 that
  broke system suspend on some Chromebooks.

  On those machines there are ACPI device objects for some I2C devices
  that can wake up the system from sleep states, but that is done via a
  platform-specific mechanism and the ACPI objects don't contain any
  wakeup-related information.  When we started to use ACPI power
  management with those devices (which happened during the 3.13 cycle),
  their configuration confused the ACPI PM layer that returned error
  codes from suspend callbacks for them causing system suspend to fail.

  However, the ACPI PM layer can safely ignore the wakeup setting from a
  device driver if the ACPI object corresponding to the device in
  question doesn't contain wakeup information in which case the driver
  itself is responsible for setting up the device for system wakeup"

As reported by Dmitry, on some Chromebooks there are devices with
corresponding ACPI objects and with unusual system wakeup
configuration.  Namely, they technically are wakeup-capable, but the
wakeup is handled via a platform-specific out-of-band mechanism and
the ACPI PM layer has no information on the wakeup capability.  As
a result, device_may_wakeup(dev) called from acpi_dev_suspend_late()
returns 'true' for those devices, but the wakeup.flags.valid flag is
unset for the corresponding ACPI device objects, so acpi_device_wakeup()
reproducibly fails for them causing acpi_dev_suspend_late() to return
an error code.  The entire system suspend is then aborted and the
machines in question cannot suspend at all.

Address the problem by ignoring the device_may_wakeup(dev) return
value in acpi_dev_suspend_late() if the ACPI companion of the device
being handled has wakeup.flags.valid unset (in which case it is clear
that the wakeup is supposed to be handled by other means).

This fixes a regression introduced by commit a76e9bd8 (i2c:
attach/detach I2C client device to the ACPI power domain) as the
affected systems could suspend and resume successfully before that
commit.

  pci 0000:00:02.2: can't handle 64-bit address space for bridge

In this kernel, unsigned long is 32 bits and dma_addr_t is 64 bits.
Previously we used "unsigned long" to hold the bridge window address.  But
this is a bus address, so we should use dma_addr_t instead.

Use dma_addr_t to hold the bridge window base and limit.

The question of whether the CPU can actually *address* the window is
separate and depends on what the physical address space of the CPU is and
whether the host bridge does any address translation.

also removed the NOP instruction after the 'jr ra' when returning

instruction was a load to the t0 register which was already in the
clobbered list, but it may have undesired effects in the future
if some other code is introduced in between the .Ldone and

When EVA is turned on and prefetching is being used in memcpy.S,
the v1 register is being used as a helper register to the PREFE
instruction. However, v1 ($3) was not in the clobber list, which
means that the compiler did not preserve it across function calls,
and that could corrupt the value of the register leading to all
sorts of userland crashes. We fix this problem by using the

 - Kernel command line specifies "earlycon" with no parameters
 - DT has a stdout-path pointing to a UART node
 - The UART driver doesn't use OF_EARLYCON_DECLARE (or maybe the console
   driver is compiled out)

[ tglx: Changed it to roundup(_brk_end, PMD_SIZE) and added a comment.
        We really should unmap the reminder along with the holes
        caused by init,initdata etc. but thats a different issue ]

In the situation when we apply early microcode but do *not* apply late
microcode, we fail to update the BSP's microcode on resume because we
haven't initialized the uci->mc microcode pointer. So, in order to
alleviate that, we go and dig out the stashed microcode patch during
early boot. It is basically the same thing that is done on the APs early
during boot so do that too here.

Add sandisk to the list of vendors. This prefix should be used
also for companies absorbed by Sandisk, like M-Systems.
