Subject: [PATCH v2 0/3] x86/irq: slightly improve handle_irq

When checking something else I stumbled across this code.
This patch set simplifies it a little bit.

v2:
- patch 2: add "likely" to if clause and reorder it
- patch 2: For 64bit, remove handle_irq and inline call to generic_handle_irq_desc

Heiner Kallweit (3):
  x86/irq: improve definition of VECTOR_SHUTDOWN et al
  x86/irq: factor out IS_ERR_OR_NULL check from platform-specific
    handle_irq
  x86/irq: slightly improve do_IRQ
