17051e42d6 drivers/sensor/hp206c: Clarify tick rate warning
The default tick rate is now 10 kHz, but that driver was demanding
that it be exactly 1 kHz instead of at least that rate.  I checked the
source, and the driver isn't actually extracting "ticks" from the
kernel illegally, it just needs fine-grained timers that work with the
existing millisecond API.  Let it build, this is fine.

0baf72e1c7 drivers/timer/nrf_rtc_timer: Fix round-up for rapid tick rates
When the tick rate was less than MIN_DELAY, bumping a "too soon"
expiration by just one tick may not be enough and we could
theoretically miss the counter.

Instead, eliminate the MIN_DELAY computation and write to the spec:
NRF guarantees that the RTC will generate an interrupt for a
comparator value two cycles in the future.  And further, we can test
at the set point to see if we "just missed" the interrupt (i.e. zero
cycles delay) and flag a synchronous interrupt.  So we only need to
miss a requested interrupt now for the special case of exactly one
cycle in the future, and then we're only late by one cycle.  That's
optimal.

Also fixes an off-by-one in the next cycle computation.  By API
convention, an ticks argument of one or less means "at the next tick"
and not "right now".  So we need to add one to the target cycle to
avoid incorrectly triggering a synchronous interrupt.  This was a
non-issue when a tick is longer than a hardware cycle but is needed
now.

Also handles the edge case with zero latency interrupts (which are
unmaskable) which might mess up timing.  This was always a problem,
but we're more sensitive now and it's comparatively more likely to
occur.

0325a3d972 arch/x86: eliminate include/arch/x86/irq_controller.h
The MVIC is no longer supported, and only the APIC-based interrupt
subsystem remains. Thus this layer of indirection is unnecessary.

This also corrects an oversight left over from the Jailhouse x2APIC
implementation affecting EOI delivery for direct ISRs only.

0d9dab300e Bluetooth: Introduce separate pool for discardable events
Introduce a separate buffer pool for events which the HCI driver
considers discardable. Examples of such events could be e.g.
Advertising Reports. The benefit of having such a pool means that the
if there is a heavy inflow of such events it will not cause the
allocation for other critical events to block and may even eliminate
deadlocks in some cases.

Also update all mesh samples not to specify explicit RX buffer counts
anymore. Instead, create appropriate defaults in Kconfig so that we
only need to override this in the app for cases like the bbc:microbit
with limited memory.

fc2fcd10cf Bluetooth: Add dedicated pool for HCI_Num_Completed_Packets HCI event
This event is a priority one, so it's not safe to have it use the RX
buffer pool which may be depleted due to non-priority events (e.g.
advertising events). Since the event is consumed synchronously it's
safe to have a single-buffer pool for it. Also introduce a new
bt_buf_get_evt() API for HCI drivers to simplify the driver-side code,
this effectively also deprecates bt_buf_get_cmd_complete() which now
has no in-tree HCI driver users anymore.

1db9f18a08 kernel/timeout: Remove "clock_always_on", replace with "SLOPPY_IDLE"
This is an oddball API.  It's untested.  In fact testing its proper
behavior requires very elaborate automation (you need a device outside
the Zephyr hardware to measure real world time, and a mechanism for
getting the device into and out of idle without using the timer
driver).  And this makes for needless difficulty managing code
coverage metrics.

It was always just a hint anyway.  Mark the old API deprecated and
replace it with a kconfig tunable.  The effect of that is just to
change the timeout value passed to the timer driver, where we can
manage code coverage metrics more easily (only one driver cares to
actually support this feature anyway).
