Hi All,

This series is a replacement for commit eed4d47efe95 (ACPI / sleep: Ignore
spurious SCI wakeups from suspend-to-idle) which is still there in 4.12-rc4 but
will be reverted shortly, because it triggered issues on quite a few systems.

The last patch in the series is a counterpart of the above commit with a few
modifications, mostly to avoid affecting suspend-to-RAM and to reorder messages
printed to kernel logs to make them somewhat less confusing.

The previous patches are pre-requisite changes plus some cleanups.  The major
ones are [1-2/6] and [4/6] that are really needed for things to work as expected
after [6/6].

In addition to that, this patch from Hans: https://patchwork.kernel.org/patch/9762815/
is needed for USB wakeup on Bay Trail and Cherry Trail systems to work in general.

Small correction, that patch currently only influences Cherry Trail devices, it has:

static const struct x86_cpu_id int0002_cpu_ids[] = {
/*
  * Limit ourselves to Cherry Trail for now, until testing shows we
  * need to handle the INT0002 device on Baytrail too.
  *     ICPU(INTEL_FAM6_ATOM_SILVERMONT1),       * Valleyview, Bay Trail *
  */
        ICPU(INTEL_FAM6_ATOM_AIRMONT),          /* Braswell, Cherry Trail */
        {}
};

If anyone sees any issues where the SCI (typically irq 9) gets a nobody
cared message on Bay Trail try the linked patch with the Bay Trail line
above uncommented.

Regards,

Hans
