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.

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.

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.

Even though the SP804 binding allows to specify only one clock, the

Specify the one clock three times and provide some clock-names, to

Based on Arnd's comment[0] all of the MStar dtsi/dts files should
have had a prefix.
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.

Most of changes are on dwc3 (38.8%) with cdns3 falling close
behind (24.1%).
The biggest changes here are a series of non-critical fixes to corner
cases on dwc3, produced by Thinh N, and a series of major improvements
to cdns3 produced by Peter C.
We also have the traditional set of new device support (Intel Keem

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).

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.
