commit 6eb4f08293e9
category: bugfix
bugzilla: 14416
CVE: NA

-------------------------------------------------

Local APIC timer clockevent parameters can be calculated based on platform
specific methods. However the code is mostly duplicated with the interrupt
based calibration. The commit which increased the max_delta parameter
updated only one place and made the implementations diverge.

Unify it to prevent further damage.

[ tglx: Rename function to lapic_init_clockevent() and adjust changelog a bit ]

Fixes: 4aed89d6 ("x86, lapic-timer: Increase the max_delta to 31 bits")
