Subject: [PATCH 0/4] genirq/irq_sim: fix a use-after-free bug + some

From: Bartosz Golaszewski <bartosz.golaszewski@...aro.org>

The first patch is an issue reported by KASAN. We're accessing freed
memory if we remove the simulator domain with irs still requested. We
must dispose of all existing mappings before we remove the domain.

The following three patches are some improvements to the interrupt
simulator. A simple header cleanup and code shrink using the new
cleanup.h helpers.

Bartosz Golaszewski (4):
  genirq/irq_sim: dispose of remaining mappings before removing the
    domain
  genirq/irq_sim: order includes alphabetically
  bitmap: define a cleanup function for bitmaps
  genirq/irq_sim: shrink code by using cleanup helpers
