Pull xen fix from Juergen Gross:
 "One fix for a regression when booting as a Xen guest on ARM64
  introduced probably during the 5.9 cycle. It is very low risk as it is
  modifying Xen specific code only.

  The exact commit introducing the bug hasn't been identified yet, but
  everything was fine in 5.8 and only in 5.9 some configurations started
  to fail"

6699e91c07 arm: disable frequency invariance for CONFIG_BL_SWITCHER
big.LITTLE switching complicates the setting of a correct cpufreq-based
frequency invariance scale factor due to (as observed in
drivers/cpufreq/vexpress-spc-cpufreq.c):
 - Incorrect current and maximum frequencies as a result of the
   exposure of a virtual frequency table to the cpufreq core,
 - Missed updates as a result of asynchronous frequency adjustments
   caused by frequency changes in other CPU pairs.

Given that its functionality is atypical in regards to frequency
invariance and this is an old technology, disable frequency
invariance for when big.LITTLE switching is configured in to prevent
incorrect scale setting.

a20b7053b5 cpufreq,arm,arm64: restructure definitions of arch_set_freq_scale()
Compared to other arch_* functions, arch_set_freq_scale() has an atypical
weak definition that can be replaced by a strong architecture specific
implementation.

The more typical support for architectural functions involves defining
an empty stub in a header file if the symbol is not already defined in
architecture code. Some examples involve:
 - #define arch_scale_freq_capacity	topology_get_freq_scale
 - #define arch_scale_freq_invariant	topology_scale_freq_invariant
 - #define arch_scale_cpu_capacity	topology_get_cpu_scale
 - #define arch_update_cpu_topology	topology_update_cpu_topology
 - #define arch_scale_thermal_pressure	topology_get_thermal_pressure
 - #define arch_set_thermal_pressure	topology_set_thermal_pressure

Bring arch_set_freq_scale() in line with these functions by renaming it to
topology_set_freq_scale() in the arch topology driver, and by defining the
arch_set_freq_scale symbol to point to the new function for arm and arm64.

While there are other users of the arch_topology driver, this patch defines
arch_set_freq_scale for arm and arm64 only, due to their existing
definitions of arch_scale_freq_capacity. This is the getter function of the
frequency invariance scale factor and without a getter function, the
setter function - arch_set_freq_scale() has not purpose.

5a0677110b arm/arm64: xen: Fix to convert percpu address to gfn correctly
Use per_cpu_ptr_to_phys() instead of virt_to_phys() for per-cpu
address conversion.

In xen_starting_cpu(), per-cpu xen_vcpu_info address is converted
to gfn by virt_to_gfn() macro. However, since the virt_to_gfn(v)
assumes the given virtual address is in linear mapped kernel memory
area, it can not convert the per-cpu memory if it is allocated on
vmalloc area.

This depends on CONFIG_NEED_PER_CPU_EMBED_FIRST_CHUNK.
If it is enabled, the first chunk of percpu memory is linear mapped.
In the other case, that is allocated from vmalloc area. Moreover,
if the first chunk of percpu has run out until allocating
xen_vcpu_info, it will be allocated on the 2nd chunk, which is
based on kernel memory or vmalloc memory (depends on
CONFIG_NEED_PER_CPU_KM).

Without this fix and kernel configured to use vmalloc area for
the percpu memory, the Dom0 kernel will fail to boot with following
errors.

f88af7229f xen/arm: do not setup the runstate info page if kpti is enabled
The VCPUOP_register_runstate_memory_area hypercall takes a virtual
address of a buffer as a parameter. The semantics of the hypercall are
such that the virtual address should always be valid.

When KPTI is enabled and we are running userspace code, the virtual
address is not valid, thus, Linux is violating the semantics of
VCPUOP_register_runstate_memory_area.

Do not call VCPUOP_register_runstate_memory_area when KPTI is enabled.

This moves the files, fixes the Makefile that generates dtbs and
fixes up the MAINTAINERS entry.

Fixing up some includes in the files themselves is left for a later
commit as rolling it into this commit resulted in a confusing diff.

acddaa5536 ARM: stm32: Replace HTTP links with HTTPS ones
Rationale:
Reduces attack surface on kernel devs opening the links for MITM
as HTTPS traffic is much harder to manipulate.

Deterministic algorithm:
For each file:
  If not .svg:
    For each line:
      If doesn't contain `\bxmlns\b`:
        For each link, `\bhttp://[^# \t\r\n]*(?:\w|/)`:
	  If neither `\bgnu\.org/license`, nor `\bmozilla\.org/MPL\b`:
            If both the HTTP and HTTPS versions
            return 200 OK and serve the same content:
              Replace HTTP with HTTPS.

737e7610b5 ARM: dts: meson8: remove two invalid interrupt lines from the GPU node
The 3.10 vendor kernel defines the following GPU 20 interrupt lines:
  #define INT_MALI_GP                 AM_IRQ(160)
  #define INT_MALI_GP_MMU             AM_IRQ(161)
  #define INT_MALI_PP                 AM_IRQ(162)
  #define INT_MALI_PMU                AM_IRQ(163)
  #define INT_MALI_PP0                AM_IRQ(164)
  #define INT_MALI_PP0_MMU            AM_IRQ(165)
  #define INT_MALI_PP1                AM_IRQ(166)
  #define INT_MALI_PP1_MMU            AM_IRQ(167)
  #define INT_MALI_PP2                AM_IRQ(168)
  #define INT_MALI_PP2_MMU            AM_IRQ(169)
  #define INT_MALI_PP3                AM_IRQ(170)
  #define INT_MALI_PP3_MMU            AM_IRQ(171)
  #define INT_MALI_PP4                AM_IRQ(172)
  #define INT_MALI_PP4_MMU            AM_IRQ(173)
  #define INT_MALI_PP5                AM_IRQ(174)
  #define INT_MALI_PP5_MMU            AM_IRQ(175)
  #define INT_MALI_PP6                AM_IRQ(176)
  #define INT_MALI_PP6_MMU            AM_IRQ(177)
  #define INT_MALI_PP7                AM_IRQ(178)
  #define INT_MALI_PP7_MMU            AM_IRQ(179)

However, the driver from the 3.10 vendor kernel does not use the
following four interrupt lines:
- INT_MALI_PP3
- INT_MALI_PP3_MMU
- INT_MALI_PP7
- INT_MALI_PP7_MMU

Drop the "pp3" and "ppmmu3" interrupt lines. This is also important
because there is no matching entry in interrupt-names for it (meaning
the "pp2" interrupt is actually assigned to the "pp3" interrupt line).

1a67b9263e ARM: imx6q: Fixup RCU usage for cpuidle
The commit eb1f00237aca ("lockdep,trace: Expose tracepoints"), started to
expose us for tracepoints. For imx6q cpuidle, this leads to an RCU splat
according to below.

[6.870684] [<c0db7690>] (_raw_spin_lock) from [<c011f6a4>] (imx6q_enter_wait+0x18/0x9c)
[6.878846] [<c011f6a4>] (imx6q_enter_wait) from [<c09abfb0>] (cpuidle_enter_state+0x168/0x5e4)

To fix the problem, let's assign the corresponding idlestate->flags the
CPUIDLE_FLAG_RCU_IDLE bit, which enables us to call rcu_idle_enter|exit()
at the proper point.
