Currently, the hrtimer_max_clock_bases is hard-coded to 3, which
makes that crash only prints three clocks, and the rest of clocks
are not displayed.
Without the patch:
crash> timer -r -C 11
CPU: 11 HRTIMER_CPU_BASE: ffff9a775f95ee00
CLOCK: 0 HRTIMER_CLOCK_BASE: ffff9a775f95ee80 [ktime_get]
(empty)
CLOCK: 1 HRTIMER_CLOCK_BASE: ffff9a775f95ef00 [ktime_get_real]
(empty)
CLOCK: 2 HRTIMER_CLOCK_BASE: ffff9a775f95ef80 [ktime_get_boottime]
(empty)
With the patch:
crash> timer -r -C 11
CPU: 11 HRTIMER_CPU_BASE: ffff9a775f95ee00
CLOCK: 0 HRTIMER_CLOCK_BASE: ffff9a775f95ee80 [ktime_get]

CLOCK: 2 HRTIMER_CLOCK_BASE: ffff9a775f95ef80 [ktime_get_boottime]
(empty)
...
