[PATCH] Compile handle_percpu_irq even for uniprocessor kernels

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



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.
