Merge branches 'acpi-x86', 'acpi-apei' and 'acpi-ec'

Browse source 
* acpi-x86:
  ACPI / x86: boot: Propagate error code in acpi_gsi_to_irq()
  ACPI / x86: boot: Don't setup SCI on HW-reduced platforms
  ACPI / x86: boot: Use INVALID_ACPI_IRQ instead of 0 for acpi_sci_override_gsi
  ACPI / x86: boot: Get rid of ACPI_INVALID_GSI
  ACPI / x86: boot: Swap variables in condition in acpi_register_gsi_ioapic()

* acpi-apei:
  ACPI / APEI: remove redundant variables len and node_len
  ACPI: APEI: call into AER handling regardless of severity
  ACPI: APEI: handle PCIe AER errors in separate function

* acpi-ec:
  ACPI: EC: Fix debugfs_create_*() usage

* PCIe AER errors need to be sent to the AER driver for reporting and
* recovery. The GHES severities map to the following AER severities and
* require the following handling:
*
* GHES_SEV_CORRECTABLE -> AER_CORRECTABLE
* These need to be reported by the AER driver but no recovery is
* necessary.
* GHES_SEV_RECOVERABLE -> AER_NONFATAL
* GHES_SEV_RECOVERABLE && CPER_SEC_RESET -> AER_FATAL
* These both need to be reported and recovered from by the AER driver.
* GHES_SEV_PANIC does not make it to this handling since the kernel must
* panic.
