The qcom_scm_set_cold/warm_boot_addr() implementations have a lot of
functionality that is actually not used.
For example, set_warm_boot_addr() caches the last used entry address
and skips making the SCM call when the entry address is unchanged.
But there is actually just a single call of qcom_scm_set_warm_boot_addr()
in the whole kernel tree, which always configures the entry address
to cpu_resume_arm().
Simplify this by having a single qcom_scm_set_boot_addr() function
for both cold and warm boot address. This is totally sufficient for
the functionality supported in the mainline tree.

At the moment, the "qcom-spm-cpuidle" platform device is always created,
even if none of the CPUs is actually managed by the SPM. On non-qcom
platforms this will result in infinite probe-deferral due to the
failing qcom_scm_is_available() call.
To avoid this, look through the CPU DT nodes and check if there is
actually any CPU managed by a SPM (as indicated by the qcom,saw property).
It should also be available because e.g. MSM8916 has qcom,saw defined
but it's typically not enabled with ARM64/PSCI firmwares.
This is needed in preparation of a follow-up change that calls
qcom_scm_set_warm_boot_addr() a single time before registering any
cpuidle drivers. Otherwise this call might be made even on devices
that have this driver enabled but actually make use of PSCI.

Quoting the header comments, IRQF_ONESHOT is "Used by threaded interrupts
which need to keep the irq line disabled until the threaded handler has
been run.". When applied to an interrupt that doesn't request a threaded
irq then IRQF_ONESHOT has a lesser known (undocumented?) side effect,
which it to disable the forced threading of the irq. For "normal" kernels
(without forced threading) then, if there is no thread_fn, then
IRQF_ONESHOT is a nop.
In this case disabling forced threading is not appropriate for this driver
because it calls wake_up_all() and this API cannot be called from
no-thread interrupt handlers on PREEMPT_RT systems (deadlock risk, triggers
sleeping-while-atomic warnings).
Fix this by removing IRQF_ONESHOT.

To speed up the boot process, as mcount_loc needs to be sorted for ftrace
to work properly, sorting it at build time is more efficient than boot up
and can save milliseconds of time. Unfortunately, this change broke s390
as it will modify the mcount_loc location after the sorting takes place
and will put back the unsorted locations. Since the sorting is skipped at
boot up if it is believed that it was sorted at run time, ftrace can crash
as its algorithms are dependent on the list being sorted.
Add a new config BUILDTIME_MCOUNT_SORT that is set when
BUILDTIME_TABLE_SORT but not if S390 is set. Use this config to determine
if sorting should take place at boot up.

Add a test which allows us to test parsing an event alias with hyphens.
Since these events typically do not exist on most host systems, add the
alias to the fake pmu.
Function perf_pmu__test_parse_init() has terms added to match known test
aliases.

supported, while foo-bar, foo_bar_baz, and other combinations are, i.e.
two hyphens are not supported.

$ ./perf list sdir-home-migrate
List of pre-defined events (to be used in -e):
uncore hha:
sdir-home-migrate
[Unit: hisi_sccl,hha]
$ sudo ./perf stat -e sdir-home-migrate
event syntax error: 'sdir-home-migrate'
\___ parser error
Run 'perf list' for a list of valid events
Usage: perf stat [<options>] [<command>]
-e, --event <event>event selector. use 'perf list' to list available events
To support, add an extra PMU event symbol type for "baz", and add a new
rule in the bison file.

A previous patch preventing "attr->sample_period" values from being
overridden in pfm events changed a related behaviour in arm-spe.
Before said patch:
perf record -c 10000 -e arm_spe_0// -- sleep 1
Would yield an SPE event with period=10000. After the patch, the period
in "-c 10000" was being ignored because the arm-spe code initializes
sample_period to a non-zero value.
This patch restores the previous behaviour for non-libpfm4 events.

Perf script was failed to print the phys_addr for SPE profiling.
One 'dummy' event is added by SPE profiling but it doesn't have PHYS_ADDR
attribute set, perf script then exits with error.
Now referring to 'addr', use evsel__do_check_stype() to check the type.
Before:
# perf record -e arm_spe_0/branch_filter=0,ts_enable=1,pa_enable=1,load_filter=1,jitter=0,\
store_filter=0,min_latency=0,event_filter=2/ -p 4064384 -- sleep 3
# perf script -F pid,tid,addr,phys_addr
Samples for 'dummy:u' event do not have PHYS_ADDR attribute set. Cannot print 'phys_addr' field.
After:
