Subject: [PATCH 0/6] genirq/test: Platform/architecture fixes

The new kunit tests at kernel/irq/irq_test.c were primarily tested on
x86_64, with QEMU and with ARCH=um builds. Naturally, there are other
architectures that throw complications in the mix, with various CPU
hotplug and IRQ implementation choices.

Guenter has been dutifully noticing and reporting these errors, in
places like:
https://lore.kernel.org/all/b4cf04ea-d398-473f-bf11-d36643aa50dd@roeck-us.net/

I hope I've addressed all the failures, but it's hard to tell when I
don't have cross-compilers and QEMU setups for all of these
architectures.

I've tested what I could on arm, powerpc, x86_64, and um ARCH.

This series is based on David's patch for these tests:

[PATCH] genirq/test: Fix depth tests on architectures with NOREQUEST by default.
https://lore.kernel.org/all/20250816094528.3560222-2-davidgow@google.com/

Brian Norris (6):
  genirq/test: Select IRQ_DOMAIN
  genirq/test: Factor out fake-virq setup
  genirq/test: Fail early if we can't request an IRQ
  genirq/test: Skip managed-affinity tests with !SPARSE_IRQ
  genirq/test: Drop CONFIG_GENERIC_IRQ_MIGRATION assumptions
  genirq/test: Ensure CPU 1 is online for hotplug test
