Subject: MIPS: Add support for fine granularity task level IRQ time accounting
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=ec9ddad3c6a5789373e4f67009a0dea276febc47;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

MIPS: Add support for fine granularity task level IRQ time accounting

With sched_clock being ready, it makes sense to add the option of IRQ time
accounting -- When we have a fast enough sched_clock, IRQ time accounting
will be enabled (see sched_clock_register).
