Qualcomm driver updates for v6.5
Konrad Dybcio is promoted, from reviewer, to co-maintainer.
The mdt_loader gets a fix to the detection of split binaries, where the
previous logic sometimes concluded that the first segments was not
split, in a split image. The unconditional calling of
scm_pas_mem_setup() turns out to cause a regression and is reverted.
The altmode subfunction of pmic_glink is enabled for SM8450.
A new driver for exposing power statistics from the RPM, for debugging
purposes, is introduced.
OCMEM gets a debug prints of the hardware version, QMI helpers are
transitioned to alloc_ordered_workqueue() and an error message in
ramp_controller is improved.
An API is introduced to the SMEM driver to allow other drivers to query
the SoC id, rather than open-coding the parsing of the relevant SMEM
item. This is then used to clean up the Qualcomm NVMEM-based cpufreq
driver.
Socinfo is extended with knowledge about IPQ5018, IPQ5312 and IPQ5302.

git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull timer fix from Thomas Gleixner:
"A single regression fix for a regression fix:
For a long time the tick was aligned to clock MONOTONIC so that the
tick event happened at a multiple of nanoseconds per tick starting
from clock MONOTONIC = 0.
At some point this changed as the refined jiffies clocksource which is
used during boot before the TSC or other clocksources becomes usable,
was adjusted with a boot offset, so that time 0 is closer to the point
where the kernel starts.
This broke the assumption in the tick code that when the tick setup
happens early on ktime_get() will return a multiple of nanoseconds per
tick. As a consequence applications which aligned their periodic
execution so that it does not collide with the tick were not longer
guaranteed that the tick period starts from time 0.
The fix for this regression was to realign the tick when it is
initially set up to a multiple of tick periods. That works as long as
the underlying tick device supports periodic mode, but breaks under
certain conditions when the tick device supports only one shot mode.
Depending on the offset, the alignment delta to clock MONOTONIC can
get in a range where the minimal programming delta of the underlying
clock event device is larger than the calculated delta to the next
tick. This results in a boot hang as the tick code tries to play catch
up, but as the tick never fires jiffies are not advanced so it keeps
trying for ever.
Solve this by moving the tick alignement into the NOHZ / HIGHRES
enablement code because at that point it is guaranteed that the
underlying clocksource is high resolution capable and not longer
depending on the tick.
This is far before user space starts, so at the point where
applications try to align their timers, the old behaviour of the tick
happening at a multiple of nanoseconds per tick starting from clock
MONOTONIC = 0 is restored"

intel_idle will, for the bare metal case, usually have one or more deep
power states that have the CPUIDLE_FLAG_TLB_FLUSHED flag set. When
a state with this flag is selected by the cpuidle framework, it will also
flush the TLBs as part of entering this state. The benefit of doing this is
that the kernel does not need to wake the cpu out of this deep power state
just to flush the TLBs... for which the latency can be very high due to
the exit latency of deep power states.
In a VM guest currently, this benefit of avoiding the wakeup does not exist,
while the problem (long exit latency) is even more severe. Linux will need
to wake up a vCPU (causing the host to either come out of a deep C state,
or the VMM to have to deschedule something else to schedule the vCPU) which
can take a very long time.. adding a lot of latency to tlb flush operations
(including munmap and others).
To solve this, add a "Long HLT" C state to the state table for the VM guest
case that has the CPUIDLE_FLAG_TLB_FLUSHED flag set. The result of that is
that for long idle periods (where the VMM is likely to do things that cause
large latency) the cpuidle framework will flush the TLBs (and avoid the
wakeups), while for short/quick idle durations, the existing behavior is
retained.
Now, there is still only "hlt" available in the guest, but for long idle,
the host can go to a deeper state (say C6). There is a reasonable debate
one can have to what to set for the exit_latency and break even point for
this "Long HLT" state. The good news is that intel_idle has these values
available for the underlying CPU (even when mwait is not exposed). The
solution thus is to just use the latency and break even of the deepest state
from the bare metal CPU. This is under the assumption that this is a pretty
reasonable estimate of what the VMM would do to cause latency.

If the intel_pstate driver is set to passive mode, then writing the
same value to the energy_performance_preference sysfs twice will fail.
This is caused by the wrong return value used (index of the matched
energy_perf_string), instead of the length of the passed in parameter.
Fix by forcing the internal return value to zero when the same
preference is passed in by user. This same issue is not present when
active mode is used for the driver.

There's no change to dtbs_install as the flat structure is maintained on
install.
The naming of vendor directories is roughly in this order of preference:
- Matching original and current SoC vendor prefix/name (e.g. ti, qcom)
- Current vendor prefix/name if still actively sold (SoCs which have
been aquired) (e.g. nxp/imx)
- Existing platform name for older platforms not sold/maintained by any
company (e.g. gemini, nspire)
The whole move was scripted with the exception of MAINTAINERS and a few
makefile fixups.

Users are having more success with amd-pstate since the introduction
of EPP and Guided modes. To expose the driver to more users by default
introduce a kernel configuration option for setting the default mode.
Users can use an integer to map out which default mode they want to use
in lieu of a kernel command line option.
This will default to EPP, but only if:
1) The CPU supports an MSR.
2) The system profile is identified
3) The system profile is identified as a non-server by the FADT.

If a user's configuration doesn't explicitly specify the cpufreq
scaling governor then the code currently explicitly falls back to
'powersave'. This default is fine for notebooks and desktops, but
servers and undefined machines should default to 'performance'.
Look at the 'preferred_profile' field from the FADT to set this
policy accordingly.

The hidraw_open() function increments the hidraw device reference
counter. The counter has no dedicated synchronization mechanism,
resulting in a potential data race when concurrently opening a device.
The race is a regression introduced by commit 8590222e4b02 ("HID:
hidraw: Replace hidraw device table mutex with a rwsem"). While
minors_rwsem is intended to protect the hidraw_table itself, by instead
acquiring the lock for writing, the reference counter is also protected.
This is symmetrical to hidraw_release().

When patching kernel alternatives, we need to be careful not to execute
kernel code which is itself subject to patching. In general, if code is
executed after the instructions in memory have been patched but prior to
the cache maintenance and barriers completing, it could lead to
UNPREDICTABLE results.
As our regular cache maintenance routines are patched with alternatives,
we have a clean_dcache_range_nopatch() function which is *intended* to
avoid patchable code and therefore supposed to be safe in the middle of
patching alternatives. Unfortunately, it's not marked as 'noinstr', and
so can be instrumented with patchable code.
Additionally, it calls read_sanitised_ftr_reg() (which may be
instrumented with patchable code) to find the sanitized value of
CTR_EL0.DminLine, and is therefore not safe to call during patching.
Luckily, since commit:
675b0563d6b26aa9 ("arm64: cpufeature: expose arm64_ftr_reg struct for CTR_EL0")
... we can read the sanitised CTR_EL0 value directly, and avoid the call
to read_sanitised_ftr_reg().
This patch marks clean_dcache_range_nopatch() as noinstr, and has it
read the sanitized CTR_EL0 value directly, avoiding the issues above.
As a bonus, this is also an optimization. As read_sanitised_ftr_reg()
performs a binary search to find the CTR_EL0 value, reading the value
directly avoids this binary search per applied alternative, avoiding
some unnecessary work.

Currently for each timestamp frame, the SW needs to go and read the
received timestamp over the MDIO bus. But the HW has the capability
to store the received nanoseconds part and the least significant two
bits of the seconds in the reserved field of the PTP header. In this
way we could save few MDIO transactions (actually a little more
transactions because the access to the PTP registers are indirect)
for each received frame.
Instead of reading the rest of seconds part of the timestamp of the
frame using MDIO transactions schedule PTP worker thread to read the
seconds part every 500ms and then for each of the received frames use
this information. Because if for example running with 512 frames per
second, there is no point to read 512 times the second part.
Doing all these changes will give a great CPU usage performance.
Running ptp4l with logSyncInterval of -9 will give a ~60% CPU
improvement.
