Vadym Kochan b1c194dcdb nvmem: core: fix missing of_node_put() in of_nvmem_device_get()
of_parse_phandle() returns device_node with incremented ref count
which needs to be decremented by of_node_put() when device_node
is not used.

Bartosz Golaszewski 1eb51d6a4f nvmem: switch to simpler IDA interface
We don't need to specify any ranges when allocating IDs so we can switch
to ida_alloc() and ida_free() instead of the ida_simple_ counterparts.

ida_simple_get(ida, 0, 0, gfp) is equivalent to
ida_alloc_range(ida, 0, UINT_MAX, gfp) which is equivalent to
ida_alloc(ida, gfp). Note: IDR will never actually allocate an ID
larger than INT_MAX.

Mike Leach 14ea4db18c coresight: etm4x: Fix number of resources check for ETM 4.3 and above
The initialisation code checks TRCIDR4 to determine the number of resource
selectors available on the system. Since ETM v 4.3, the value 0 has a

and the pair 0 is always implemented and reserved.
So let's multiply by 2 when resetting the selector configuration.
And also update the validation of the input @idx.

Linu Cherian 6d578258b9 coresight: Make sysfs functional on topologies with per core sink
Coresight driver assumes sink is common across all the ETMs,
and tries to build a path between ETM and the first enabled
sink found using bus based search. This breaks sysFS usage
on implementations that has multiple per core sinks in
enabled state.

To fix this, coresight_get_enabled_sink API is updated to
do a connection based search starting from the given source,
instead of bus based search.
With sink selection using sysfs depecrated for perf interface,
provision for reset is removed as well in this API.

Suzuki K Poulose 859d510e58 coresight: etm4x: Handle unreachable sink in perf mode
If the specified/hinted sink is not reachable from a subset of the CPUs,
we could end up unable to trace the event on those CPUs. This
is the best effort we could do until we support 1:1 configurations.
Fail gracefully in such cases avoiding a WARN_ON, which can be easily
triggered by the user on certain platforms (Arm N1SDP), with the following
trace paths :

 CPU0
      \
       -- Funnel0 --> ETF0 -->
      /                        \
 CPU1                           \
                                  MainFunnel
 CPU2                           /
      \                        /
       -- Funnel1 --> ETF1 -->
      /
 CPU1

$ perf record --per-thread -e cs_etm/@ETF0/u -- <app>

could trigger the following WARNING, when the event is scheduled
on CPU2.

Even though we don't support using separate sinks for the ETMs yet (e.g,
for 1:1 configurations), we should at least honor the user's choice and
handle the limitations gracefully, by simply skipping the tracing on ETMs
which can't reach the requested sink.

Mike Leach 096dcfb9cd coresight: etm4x: Ensure default perf settings filter user/kernel
Moving from using an address filter to trace the default "all addresses"
range to no filtering to acheive the same result, has caused the perf
filtering of kernel/user address spaces from not working unless an
explicit address filter was used.

This is due to the original code using a side-effect of the address
filtering rather than setting the global TRCVICTLR exception level
filtering.

The use of the mode sysfs file is also similarly affected.

A helper function is added to fix both instances.

which could sleep. Remove pm_runtime_get_sync() in cti_cpuhp_enable_hw()
since pm_runtime_get_sync() is called in cti_enabld and pm_runtime_put()
is called in cti_disabled. No need to increase pm count when CPU gets
online since it's not decreased when CPU is offline.

Sai Prakash Ranjan 2d1a8bfb61 coresight: etm4x: Fix etm4_count race by moving cpuhp callbacks to init
etm4_count keeps track of number of ETMv4 registered and on some systems,
a race is observed on etm4_count variable which can lead to multiple calls
to cpuhp_setup_state_nocalls_cpuslocked(). This function internally calls
cpuhp_store_callbacks() which prevents multiple registrations of callbacks
for a given state and due to this race, it returns -EBUSY leading to ETM
probe failures like below.

 coresight-etm4x: probe of 7040000.etm failed with error -16

This race can easily be triggered with async probe by setting probe type
as PROBE_PREFER_ASYNCHRONOUS and with ETM power management property
"arm,coresight-loses-context-with-cpu".

Prevent this race by moving cpuhp callbacks to etm driver init since the
cpuhp callbacks doesn't have to depend on the etm4_count and can be once
setup during driver init. Similarly we move cpu_pm notifier registration
to driver init and completely remove etm4_count usage. Also now we can
use non cpuslocked version of cpuhp callbacks with this movement.

Maxim Levitsky 37f66bbef0 KVM: emulator: more strict rsm checks.
Don't ignore return values in rsm_load_state_64/32 to avoid
loading invalid state from SMM state area if it was tampered with
by the guest.

This is primarly intended to avoid letting guest set bits in EFER
(like EFER.SVME when nesting is disabled) by manipulating SMM save area.

Maxim Levitsky 3ebb5d2617 KVM: nSVM: more strict SMM checks when returning to nested guest
* check that guest is 64 bit guest, otherwise the SVM related fields
  in the smm state area are not defined

* If the SMM area indicates that SMM interrupted a running guest,
  check that EFER.SVME which is also saved in this area is set, otherwise
  the guest might have tampered with SMM save area, and so indicate
  emulation failure which should triple fault the guest.

* Check that that guest CPUID supports SVM (due to the same issue as above)
