Subject: Compile handle_percpu_irq even for uniprocessor kernels
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=28e3fed8b79c76450f264e77c58d0f5fbd2dd739;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

Compile handle_percpu_irq even for uniprocessor kernels

Compiling handle_percpu_irq only on uniprocessor generates an artificial
special case so a typical use like:

  set_irq_chip_and_handler(irq, &some_irq_type, handle_percpu_irq);

needs to be conditionally compiled only on SMP systems as well and an
alternative UP construct is usually needed - for no good reason.

This fixes uniprocessor configurations for some MIPS SMP systems.
