Pull ARM SoC platform updates from Arnd Bergmann:
"The 32-bit Arm platforms are a bit more interesting this time: I
refreshed an earlier series to mark code as deprecated that does have
the tendency of getting in the way of cleanups and new features but
has close to zero users. Among these are:
- 22 of the remaining 28 legacy board files that predate the current
devicetree based descriptions, using old chips from Intel and
Marvell. The remaining six board files are for TI OMAP1 and Samsung
s3c64xx chips and all still have known users.
- support for Cortex-M3/M4/M7 and ARM1136r0 CPU cores and the 25
machines based on these. These all use devicetree but the CPU
support causes disproportional work. Most of them are just
reference boards, the notable exceptions being the Nokia N800/N810
tablet and the Buglabs BUG platform.

The final patch switching Alpha to GENERIC_ENTRY is intentionally not

- Fix a subtly inconsistency in the timekeeping code, which fails to

For small changes of the clocksource multiplicator (+/-1) which are
typically used by the NTP PLL this is hard to observe. But for larger
adjustments, e.g. caused by a direct frequency setting through
adjtimex() the one-time uncompensated offset is significant.
Cure this by adjusting ntp_error with the resulting offset so that
the discrepancy is smoothed away over time
- Make tick length calculations correct in NTP.
The timekeeping core takes the quantisation of the clocksource into
account when calculating the tick length to compensate for the

Pull treewide timer related cleanups from Thomas Gleixner:
- Remove the leftover CLOCK_TICK_RATE which has been scheduled for
removal more than a decade ago along with some now empty asm/timex.h
files.
- Consolidate delay timer calibration
The construct of having a define in a header requires that
architectures provided asm/timex.h for no reason. Also the function
name for reading the delay timer is confusing at best.
Use a config switch to enable that functionality and rename the
function to delay_read_timer() to make the purpose clear.
This removes some more now empty asm/timex.h files as well.

Pull SMP core updates from Thomas Gleixner:
- Reduce the preemption disabled sections in smp_call_function*().
The various smp call functions keep preemption disabled accross the
full operation which includes the wait for completion. Especially the
latter can take some time when one of the target CPUs is not
immediately responding to the IPI, which can result in large latency
spikes.
To improve this provide a per task CPU mask to track the CPUs to wait
for. That makes the information required for the wait task local and
therefore allows to reenable preemption before the wait.
While this comes with moderate extra memory cost this reduces SMP
function call induced latency measured in a fleet for high priority
tasks from ~17ms to ~1.5ms (~90%).
