This series is a split-off of the x86/TSC related patches from the
"avoid double timer interrupt with nohz and Intel TSC" v2 series
(http://lkml.kernel.org/g/20160710193047.18320-1-nicsta...@gmail.com).
It turned out that the non-x86 related parts of the aforementioned series
are more than arguable and I don't want to bother you with any further
discussion of those. I apologize for any confusion this split might cause.
Applicable to linux-next-20160712. The individual patches don't depend on
each other.
Changes to v2:
- [3/3] ("arch, x86, tsc: inform TSC deadline clockevent device about
recalibration")
Use clockevents_update_freq() rather than clockevents_config().
- Former [4/4] ("kernel/time/clockevents: compensate for monotonic
clock's dynamic frequency")
Split off, not a member of this series anymore.
Changes to v1:
- [1/3] ("arch, x86, tsc deadline clockevent dev: reduce frequency
roundoff error")
No changes to the patch. Note that the v1 mail could not be delivered
to the author of the TSC_DIVISOR introducing commit 279f1461432c
("x86: apic: Use tsc deadline for oneshot when available"),
Suresh Siddha <suresh.b.sid...@intel.com>, so I had to remove him
from the CC list.
- [2/3] ("arch, x86, tsc deadline clockevent dev: reduce TSC_DIVISOR
to 2")
Likewise.
- [3/3] ("arch, x86, tsc: inform TSC deadline clockevent device about
recalibration")
Silence the kbuild test robot on ARCH=i386 by wrapping the new call
to lapic_update_tsc_freq() from arch/x86/kernel/tsc.c in an
#ifdef CONFIG_X86_LOCAL_APIC.
