Pull more ACPI updates from Rafael Wysocki:
 "These fix two issues, in APEI and in the int3472 driver, clean up the
  ACPI thermal driver, add ACPI support for non-GPE system wakeup events
  and make the system reboot code use the S5 (system off) state by
  default.

  Specifics:

   - Fix ACPI device object reference counting in (recently updated)
     skl_int3472_fill_clk_pdata() (Andy Shevchenko).

   - Fix a memory leak in APEI by avoiding to add a task_work to kernel
     threads running when an asynchronous error is detected (Shuai Xue).

   - Add ACPI support for handling system wakeups via GPIO wake capable
     IRQs in addition to GPEs (Raul E Rangel).

   - Make the system reboot code put ACPI-enabled systems into the S5
     (system off) state which is necessary for some platforms to work as
     expected (Kai-Heng Feng).

   - Make the white space usage in the ACPI thermal driver more
     consistent and drop redundant code from it (Rafael Wysocki)"

ACPI IRQ/Interrupt resources contain a bit that describes if the
interrupt should wake the system. This change exposes that bit via
a new IORESOURCE_IRQ_WAKECAPABLE flag. Drivers should check this flag
before arming an IRQ to wake the system.

The ACPI spec defines the SharedAndWake and ExclusiveAndWake share type
keywords. This is an indication that the GPIO IRQ can also be used as a
wake source. This change exposes the wake_capable bit so drivers can
correctly enable wake functionality instead of making an assumption.

Use _DMA defined in ACPI spec for translation between
DMA address and CPU address, and implement acpi_arch_dma_setup
for initializing dev-&gt;dma_range_map, where acpi_dma_get_range
is called for parsing _DMA.

e.g.
If we have two dma ranges:
cpu address      dma address    size         offset
0x200080000000   0x2080000000   0x400000000  0x1fe000000000
0x400080000000   0x4080000000   0x400000000  0x3fc000000000

_DMA for pci devices should be declared in host bridge as
flowing:

Name (_DMA, ResourceTemplate() {
        QWordMemory (ResourceProducer,
            PosDecode,
            MinFixed,
            MaxFixed,
            NonCacheable,
            ReadWrite,
            0x0,
            0x4080000000,
            0x447fffffff,
            0x3fc000000000,
            0x400000000,
            ,
            ,
            )

        QWordMemory (ResourceProducer,
            PosDecode,
            MinFixed,
            MaxFixed,
            NonCacheable,
            ReadWrite,
            0x0,
            0x2080000000,
            0x247fffffff,
            0x1fe000000000,
            0x400000000,
            ,

<id>urn:sha1:bf2ee8d0c385f883a00473768b67faf2189b2410</id>
<content type='text'>
In DT systems configurations, of_dma_get_range() returns struct
bus_dma_region DMA regions; they are used to set-up devices
DMA windows with different offset available for translation between DMA
address and CPU address.

In ACPI systems configuration, acpi_dma_get_range() does not return
DMA regions yet and that precludes setting up the dev-&gt;dma_range_map
pointer and therefore DMA regions with multiple offsets.

Update acpi_dma_get_range() to return struct bus_dma_region
DMA regions like of_dma_get_range() does.

After updating acpi_dma_get_range(), acpi_arch_dma_setup() is changed for
ARM64, where the original dma_addr and size are removed as these
arguments are now redundant, and pass 0 and U64_MAX for dma_base
and size of arch_setup_dma_ops; this is a simplification consistent
with what other ACPI architectures also pass to iommu_setup_dma_ops().

have an integer representation of _UID. Add respective helper for that.
