From: Rik van Riel <r...@redhat.com>
Allow CONFIG_IRQ_TIME_ACCOUNTING to be selected as an option, on top
of CONFIG_VIRT_CPU_ACCOUNTING_GEN (and potentially others?).
This allows for the irq time accounting code to be used with nohz_idle
CPUs, which is how several distributions ship their kernels. Using the
same code for several timer modes also allows us to drop duplicate code.
