up to: e2a71bdea816: timer: Fix wheel index calculation on last level
Two fixes for the timer wheel:
- A timer which is already expired at enqueue
The LB_BIAS feature was removed in commit 1c1b8a7b03ef ("sched/fair:
Replace source_load() & target_load() with weighted_cpuload()"), so drop
the mention that it is disabled in the no_hz case.

Looks correct to me, but I forgot everything about posix-timers.c
this obviously means that the expired timer won't fire until the
task returns to user-mode but probably we don't care.

So far next expiry was only tracked while the CPU was in nohz_idle mode
in order to cope with missing ticks that can't increment the base->clk
periodically anymore.
We are going to expand that logic beyond nohz in order to spare timers
softirqs so do it unconditionally.
Tested-by: Juri Le
This set piggybacks the 3 patches that have been posted seperately
along the reviews.
Changes since v2:
1) Add "timer: Fix wheel index calculation on last level"
This one targets timers/urgent
2) Add "timer: Preserve higher bits of expiration on index calculation"
From: Anna-Maria Behnsen
The bucket expiry time is the effective expriy time of timers and is
greater than or equal to the requested timer expiry time. This is due
to the guarantee that timers never expire early and the reduced expiry
granularity in the secondary wheel levels.

If the expiry happens in task context, there is no point in collecting the
expired timers on a list first. Just expire them directly.

Running posix cpu timers in hard interrupt context has a few downsides:
- For PREEMPT_RT it cannot work as the expiry code needs to take
sighand lock, which is a 'sleeping spinlock' in RT. The original RT
approach of offloading the posix CPU timer handling into a high
priority thread
This is the second attempt of moving the posix CPU timer heavy lifting out
of interrupt context. The initial version can be found here:

ARM64_WORKAROUND_1418040 requires that AArch32 EL0 accesses to
the virtual counter register are trapped and emulated by the kernel.

prone.

The main issue here is that the tick fires the timer tick unconditionally,
whether timers have expired or not. This set is a proposal to lower that.
The 1st patch is actually a bugfix for a theoretical issue that I haven't
observed in practice. But who knows?
