This patch enables NO_HZ_IDLE (idle dynamic ticks) and HIGH_RES_TIMERS
(hrtimers) in RV32 and RV64 defconfigs.
Both of the above options are enabled by default for architectures
such as x86, ARM, and ARM64.
The idle dynamic ticks helps use save power by stopping timer ticks
when the system is idle whereas hrtimers is a much improved timer
subsystem compared to the old "timer wheel" based system.
This patch is tested on SiFive Unleashed board and QEMU Virt machine.

My only issue here is testing: IIRC last time we tried this it ended up causing
trouble. I'm in the process of switching to Yocto right now for my tests, so
it'll be a bit slow.

Are you talking about the trouble with CONFIG_NO_HZ_IDLE we were seeing last year or something else ?
CONFIG_NO_HZ_IDLE was well tested and fixed last year.

I've been running kernels with these settings since the beginning, and
never seen any trouble.
