Prior to the adoption of SPDX, it was difficult for tools to determine
the correct license due to incomplete or badly formatted license text.
The SPDX solves this issue, assuming people can correctly spell
"SPDX-License-Identifier" although this assumption is broken in some
places.

Since scripts/spdxcheck.py parses only lines that exactly matches to
the correct tag, it cannot (should not) detect this kind of error.

If the correct tag is missing, scripts/checkpatch.pl warns like this:

 WARNING: Missing or malformed SPDX-License-Identifier tag in line *

So, people should notice it before the patch submission, but in reality
broken tags sometimes slip in. The checkpatch warning is not useful for
checking the committed files globally since large number of files still
have no SPDX tag.

Also, I am not sure about the legal effect when the SPDX tag is broken.

Anyway, these typos are absolutely worth fixing. It is pretty easy to
find suspicious lines by grep.

  $ git grep --not -e SPDX-License-Identifier --and -e SPDX- -- \

Pull more power management updates from Rafael Wysocki:
 "These fix a recent regression causing kernels built with CONFIG_PM
  unset to crash on systems that support the Performance and Energy Bias
  Hint (EPB), clean up the cpufreq core and some users of transition
  notifiers and introduce a new power domain flag into the generic power
  domains framework (genpd).

  Specifics:

   - Fix recent regression causing kernels built with CONFIG_PM unset to
     crash on systems that support the Performance and Energy Bias Hint
     (EPB) by avoiding to compile the EPB-related code depending on
     CONFIG_PM when it is unset (Rafael Wysocki).

   - Clean up the transition notifier invocation code in the cpufreq
     core and change some users of cpufreq transition notifiers
     accordingly (Viresh Kumar).

   - Change MAINTAINERS to cover the schedutil governor as part of
     cpufreq (Viresh Kumar).

   - Simplify cpufreq_init_policy() to avoid redundant computations (Yue
     Hu).

   - Add explanatory comment to the cpufreq core (Rafael Wysocki).

   - Introduce a new flag, GENPD_FLAG_RPM_ALWAYS_ON, to the generic
     power domains (genpd) framework along with the first user of it
     (Leonard Crestez)"

* tag 'pm-5.2-rc1-2' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm:
  soc: imx: gpc: Use GENPD_FLAG_RPM_ALWAYS_ON for ERR009619

This prepares to move CONFIG_OPTIMIZE_INLINING from x86 to a common
place.  We need to eliminate potential issues beforehand.

If it is enabled for arm, Clang build results in the following modpost
warning:

  WARNING: vmlinux.o(.text+0x1124): Section mismatch in reference from the function setup_machine_tags() to the function .init.text:early_print()
  The function setup_machine_tags() references the function __init early_print().
  This is often because setup_machine_tags lacks a __init annotation or the annotation of early_print is wrong.

<title>ARM: prevent tracing IPI_CPU_BACKTRACE</title>

Patch series "compiler: allow all arches to enable
CONFIG_OPTIMIZE_INLINING", v3.

This patch (of 11):

When function tracing for IPIs is enabled, we get a warning for an
overflow of the ipi_types array with the IPI_CPU_BACKTRACE type as
triggered by raise_nmi():

  arch/arm/kernel/smp.c: In function 'raise_nmi':
  arch/arm/kernel/smp.c:489:2: error: array subscript is above array bounds [-Werror=array-bounds]
    trace_ipi_raise(target, ipi_types[ipinr]);

This is a correct warning as we actually overflow the array here.

This patch raise_nmi() to call __smp_cross_call() instead of
smp_cross_call(), to avoid calling into ftrace.  For clarification, I'm
also adding a two new code comments describing how this one is special.

The warning appears to have shown up after commit e7273ff49acf ("ARM:
8488/1: Make IPI_CPU_BACKTRACE a "non-secure" SGI"), which changed the
number assignment from '15' to '8', but as far as I can tell has existed
since the IPI tracepoints were first introduced.  If we decide to
backport this patch to stable kernels, we probably need to backport
e7273ff49acf as well.
