Subject: [PATCH v3 0/3] x86/platform/intel-mid: Fix RTC handling

Current RTC approach breaks some platforms. Rewrite it completely and
make avaiable only for intended platforms.

Tested on Intel Merrifield, ASuS T100TA (normal and acpi=off cases).

Since v2:
- add mp_map_gsi_to_irq() fix to the series as patch 1
- add patch 3
- rewrite RTC approach as another platform code for Intel MID

Andy Shevchenko (3):
  x86/ioapic: Return suitable error code in mp_map_gsi_to_irq()
  x86/platform/intel-mid: Allocate RTC interrupt for Merrifield
  x86/platform/intel-mid: Don't shadow error code of mp_map_gsi_to_irq()
