Pull power management updates from Rafael Wysocki:
"These add some new hardware support (for example, IceLake-D idle
states in intel_idle), fix some issues (for example, the handling of
negative "sleep length" values in cpuidle governors), add new
functionality to the existing drivers (for example, scale-invariance
support in the ACPI CPPC cpufreq driver) and clean up code all over.
Specifics:
- Add idle states table for IceLake-D to the intel_idle driver and
update IceLake-X C6 data in it (Artem Bityutskiy).

drop the unused do_idle() firmware call from it (Dmitry Osipenko).
- Fix cpuidle-qcom-spm Kconfig entry (He Ying).
- Fix handling of possible negative tick_nohz_get_next_hrtimer()
return values of in cpuidle governors (Rafael Wysocki).

driver and update the frequency-invariance engine (FIE) to use it
as needed (Viresh Kumar).

driver (Tom Saeger).
- Clean up frequency-related computations in the intel_pstate cpufreq
driver (Rafael Wysocki).

driver and drop the CPU PM clock .set_parent method for armada-37xx
(Marek Behún).
- Fix multiple issues in the armada-37xx cpufreq driver (Pali Rohár).

unnecessary overhead (Yue Hu).
- Fix typos in the s5pv210 cpufreq driver (Bhaskar Chowdhury).
- Fix cpufreq documentation links in Kconfig (Alexander Monakov).

resource (Rafael Wysocki).
- Add missing documentation of pm_runtime_resume_and_get() (Alan
Stern).
- Add missing static inline stub for pm_runtime_has_no_callbacks() to

Remove the family check for accessing the MSR_AMD_HWCR MSR and replace
it with a cpupower cap flag.
This update also allows for the removal of the local cpupower_cpu_info
variable in cpufreq_has_boost_support() since we no longer need it to
check the family.

The pscur variable is set but not uused, just remove it.
This may have previsously been set to validate the MSR_AMD_PSTATE_STATUS
MSR. With the addition of the CPUPOWER_CAP_AMD_HW_PSTATE cap flag this
is no longer needed since the cpuid bit to enable this cap flag also
validates that the MSR_AMD_PSTATE_STATUS MSR is present.

Add a check in get_cpu_info() for the ability to read frequencies
from hardware and set the CPUPOWER_CAP_AMD_HW_PSTATE cpuid flag.
The cpuid flag is set when CPUID_80000007_EDX[7] is set,
which is all families >= 10h. The check excludes family 14h
because HW pstate reporting was not implemented on family 14h.
This is intended to reduce family checks in the main code paths.

The msr_pstate union struct named fam17h_bits is misleading since
this is the struct to use for all families >= 0x17, not just
for family 0x17. Rename the bits structs to be 'pstate' (for pre
family 17h CPUs) and 'pstatedef' (for CPUs since fam 17h) to align
closer with PPR/BDKG (1) naming.
There are no functional changes as part of this update.

6d6501d912a9 ("tools/power/turbostat: Read energy_perf_bias from sysfs")
converted turbostat to read the energy_perf_bias value from sysfs.
However, older kernels which do not have that file yet, would fail. For
those, fall back to the MSR reading.

In some case when BIOS disabled turbo, cpufreq cpuinfo_max_freq can be
lower than base_frequency at higher config level. So, in that case set
scaling_min_freq to base_frequency.

When BIOS disables turbo, The scaling_max_freq in cpufreq sysfs will be
limited to config level 0 base frequency. But when user selects a higher
config levels, this will result in higher base frequency. But since
scaling_max_freq is still old base frequency, the performance will still
be limited. So when the turbo is disabled and cpufreq base_frequency is
higher than scaling_max_freq, update the scaling_max_freq to the
base_frequency.

When a user tries to modify cpuidle or cpufreq properties on offline
CPUs, the tool returns success (exit status 0) but also does not provide
any warning message regarding offline cpus that may have been specified
but left unchanged. In case of all or a few CPUs being offline, it can be
difficult to keep track of which CPUs didn't get the new frequency or idle
state set. Silent failures are difficult to keep track of when there are a
huge number of CPUs on which the action is performed.
This patch adds helper functions to find both online and offline CPUs and
print them out accordingly.
We use these helper functions in cpuidle-set and cpufreq-set to print an
additional message if the user attempts to modify offline cpus.

Some older kernels will not have support to get CPU die_id from the
sysfs. This requires several back ports. But the tool depends on getting
die_id to match to correct CPU.
Relax this restriction and use die_id as 0 when die_id is missing. This
is not a problem as we don't have any multi-die processors with Intel SST
support.
This helps in running this tool on older kernels with just Intel SST
drivers back ported.

When SST-PP feature is not present, the TRL (Turbo Ratio Limits)
is read from MSRs. This is done as the mailbox command will fail
on Skylake-X based platform. But for IceLake servers, mailbox
commands can still be used. So add a check to allow for non Skylake
based platforms to read from mail box commands.

Pull networking updates from Jakub Kicinski:
"Core:

softirq for some time expecting applications to periodically busy
poll
- AF_XDP: improve efficiency by more batching and hindering the
adjacency cache prefetcher
- af_packet: make packet_fanout.arr size configurable up to 64K

unaligned reads making zero copy a performance win for much smaller
messages

APIs and have the drivers write a full IRQ handler, slight growth
of driver code should be compensated by the simpler API which also
allows shared IRQs

central place

====================
pull-request: bpf-next 2020-11-14
1) Add BTF generation for kernel modules and extend BTF infra in kernel
e.g. support for split BTF loading and validation, from Andrii Nakryiko.
2) Support for pointers beyond pkt_end to recognize LLVM generated patterns
on inlined branch conditions, from Alexei Starovoitov.
3) Implements bpf_local_storage for task_struct for BPF LSM, from KP Singh.
4) Enable FENTRY/FEXIT/RAW_TP tracing program to use the bpf_sk_storage
infra, from Martin KaFai Lau.
5) Add XDP bulk APIs that introduce a defer/flush mechanism to optimize the
XDP_REDIRECT path, from Lorenzo Bianconi.
6) Fix a potential (although rather theoretical) deadlock of hashtab in NMI
context, from Song Liu.
7) Fixes for cross and out-of-tree build of bpftool and runqslower allowing build
for different target archs on same source tree, from Jean-Philippe Brucker.
8) Fix error path in htab_map_alloc() triggered from syzbot, from Eric Dumazet.
9) Move functionality from test_tcpbpf_user into the test_progs framework so it
can run in BPF CI, from Alexander Duyck.
10) Lift hashtab key_size limit to be larger than MAX_BPF_STACK, from Florian Lehner.
Note that for the fix from Song we have seen a sparse report on context
imbalance which requires changes in sparse itself for proper annotation
detection where this is currently being discussed on linux-sparse among
developers [0]. Once we have more clarification/guidance after their fix,
Song will follow-up.

Pull misc x86 updates from Borislav Petkov:
"The main part of this branch is the ongoing fight against windmills in
an attempt to have userspace tools not poke at naked MSRs.
This round deals with MSR_IA32_ENERGY_PERF_BIAS and removes direct
poking into it by our in-tree tools in favor of the proper
"energy_perf_bias" sysfs interface which we already have.
In addition, the msr.ko write filtering's error message points to a
new summary page which contains the info we collected from helpful
reporters about which userspace tools write MSRs:
https://git.kernel.org/pub/scm/linux/kernel/git/tip/tip.git/about
