CONFIG_PM means that at least one of CONFIG_PM_SLEEP and
CONFIG_PM_RUNTIME is enabled, while multiple entries in
mach-exynos/Kconfig abused it to enable sleep- and runtime-specific
functionality.
This patch fixes this abuse by replacing dependencies on CONFIG_PM with
appropriate dependencies on either CONFIG_PM_SLEEP or CONFIG_PM_RUNTIME,
whichever is appropriate.

Subject: [PATCH] arm, kvm: Fix CPU hotplug callback registration
Subsystems that want to register CPU hotplug callbacks, as well as perform
initialization for the CPUs that are already online, often do it as shown
below:
get_online_cpus();
for_each_online_cpu(cpu)
init_cpu(cpu);
register_cpu_notifier(&foobar_cpu_notifier);
put_online_cpus();
This is wrong, since it is prone to ABBA deadlocks involving the
cpu_add_remove_lock and the cpu_hotplug.lock (when running concurrently
with CPU hotplug operations).
Instead, the correct and race-free way of performing the callback
registration is:
cpu_notifier_register_begin();
for_each_online_cpu(cpu)
init_cpu(cpu);
/* Note the use of the double underscored version of the API */
__register_cpu_notifier(&foobar_cpu_notifier);
cpu_notifier_register_done();
In the existing arm kvm code, there is no synchronization with CPU hotplug
to avoid missing the hotplug events that might occur after invoking
init_hyp_mode() and before calling register_cpu_notifier(). Fix this bug
and also use the new synchronization method (instead of get/put_online_cpus())
to ensure that we don't deadlock with CPU hotplug.

This patch series adds basic uprobes support to ARM. It is based on
patches developed earlier by Rabin Vincent. That approach of adding
hooks into the kprobes instruction parsing code was not well received.
This approach separates the ARM instruction parsing code in kprobes out
into a separate set of functions which can be used by both kprobes and
uprobes. Both kprobes and uprobes then provide their own semantic action
tables to process the results of the parsing.
Two cpufreq notifiers CPUFREQ_RESUMECHANGE and CPUFREQ_SUSPENDCHANGE have
not been used for some time, so remove them to clean up code a bit.

As there is no common panel framework in the kernel, we have OMAP
specific panel drivers. However, the DT data should be generic. This
brings the issue that some other platform could use the same panels, and
would need to create a driver with the same 'compatible' string as the
OMAP driver.
In the long run, we have to get a common panel framework. For the time
being, this patch solves the issue:
At early boot time, we go through the DT nodes looking for the panels
the kernel supports for OMAP. For each found node, the 'compatible'
string is prepended with "omapdss,", i.e. "sony,acx565akm" becomes
"omapdss,sony,acx565akm". The OMAP display drivers all have "omapdss,"
at the beginning of their compatible field.
This allows us to have generic DT data, but OMAP specific display
drivers.

The DSS fclk and iclk handles are named differently on OMAP3430 ES1 than
on later OMAP revisions. The ES1 has handles 'dss1_alwon_fck_3430es1'
and 'dss_ick_3430es1', whereas later revisions have similar names but
ending with 'es2'.
This means we don't have one clock handle to which we could refer to
when defining the DSS clocks.
However, as the namespaces are separate for ES1 and ES2+ OMAPs, we can
just rename the handles to 'dss1_alwon_fck' and 'dss_ick' for both ES1
and ES2+, removing the issue.

Because the common underlying code for ARM kprobes and uprobes needs

the generic kprobes include file insists on defining this to a dummy

required which can exist when uprobes is configured without kprobes.

The USB host drivers need platform data to be defined on
pxa168 and pxa910, but the conditionals used in the devices.c
file only work if the drivers are built-in. This patch
fixes the definition by changing the #ifdef to #if IS_ENABLED(),
which works both for built-in and modular Kconfig symbols.
I found one specific problem using 'randconfig' builds, but
for consistency, this patch uses IS_ENABLED() for all Kconfig
symbols in these three files.

The grant mapping API does m2p_override unnecessarily: only gntdev needs it,
for blkback and future netback patches it just cause a lock contention, as
those pages never go to userspace. Therefore this series does the following:
- the bulk of the original function (everything after the mapping hypercall)
is moved to arch-dependent set/clear_foreign_p2m_mapping
- the "if (xen_feature(XENFEAT_auto_translated_physmap))" branch goes to ARM
- therefore the ARM function could be much smaller, the m2p_override stubs
could be also removed
- on x86 the set_phys_to_machine calls were moved up to this new funcion
from m2p_override functions
- and m2p_override functions are only called when there is a kmap_ops param
It also removes a stray space from arch/x86/include/asm/xen/page.h.

The prima2 platform code currently depends on the rstc
implementation and that in turn depends on the reset
controller framework. This removes the platform dependency
by letting the driver access arm_pm_restart directly
to turn the driver into a standalone entity, and also
removes the dependency on the reset controller framework
by using "if (IS_ENABLED(CONFIG_RESET_CONTROLLER))". This
will cause all code that is used for the reset controller
to be dropped by the compiler if the framework is disabled.

This patch fixes the following BUG:
> kernel BUG at mm/vmalloc.c:1132!
> PC is at vm_area_add_early+0x20/0x84
> LR is at add_static_vm_early+0xc/0x60
>
> The problem is cns3xxx_pcie_init() (device_initcall) calls the "early"
> iotable_init().
Instead of merely calling the PCIe iotable_init() from
machine_desc->map_io(), this patch adds the required mappings to the
main CNS3xxx mapping table. This means we don't convert .pfn back to
virtual addresses in pcie.c. The size of the address space consumed for
PCIe control is reduced from 96 MiB (6 * 16 MiB) to about 32 MiB (this
doesn't include MMIO address space required by PCI devices):
- Size of the PCIe "host" mapping is reduced from 16 MiB to 4 KiB.
It's a PCI configuration address space for the local (on-chip) PCIe
bridge.
- Size of the "CFG0" mapping is reduced from 16 MiB to 64 KiB. It's for
Type 0 Configuration accesses, i.e., accesses to the single device
(with possible "functions") on the other end of the PCIe link.
We really only need a 4 KiB page at 0x8000 (see the offset
calculation in cns3xxx_pci_cfg_base()). There is still a potential
problem with PCI bus numbers > 0xF, are they supported?
- The code in cns3xxx_pci_cfg_base() and cns3xxx_pcie_hw_init() should
be clearer now.
- The maximum address space allocated for PCI MMIO is now correctly
shown in /proc/iomem as 176 MiB (per each of the two PCI "domains"
- previously only 16 MiB were reserved).
This patch has been tested on Gateworks Laguna board, masqueraded as
CNS3420VB.

The tnetv107x support does not compile, and seems to have been broken
for a while with nobody caring to fix it. So far everyone I asked
said it's probably dead and completely unused and will never again
be needed in a future kernel release, so let's delete it.
If someone finds a use for this code later and is able to get it
to work again, we can always revert the removal.

When an interrupt has become active on the INTC it will stay active
until it is acked, even if masked or de-asserted. The
INTC_PENDING_IRQn registers are however updated and since these are
used by omap_intc_handle_irq to determine which interrupt to handle,
it will never see the active interrupt. This will result in a storm of
useless interrupts that is only stopped when another higher priority
interrupt is asserted.
Fix by sending the INTC an acknowledge if we find no interrupts to
handle.

This patch prepare the transition to common clk for sam9 dt boards by
replacing the timer init callback.
Clocks registration cannot be done in early init callback (as formerly done
by the old clk implementation) because it requires dynamic allocation
which is not ready yet during early init.
In the other hand, at91 clocks must be registered before
at91sam926x_pit_init is called because PIT (Periodic Interval Timer) driver
request the master clk (mck).
A new function (at91sam9_dt_timer_init) is created to fullfil these needs.
This function registers all at91 clks using the dt definition before
calling the PIT init function.
The device tree clock registration is enabled only if common clk is
selected. Else the old clk registration is been done during
at91_dt_initialize call.

As multiplatform build is being adopted by more and more
ARM platforms, initcall function should be used very carefully.
For example, when SPEAr cpufreq driver is enabled on a kernel
booted on a non-SPEAr board, we will get following boot time error:
spear_cpufreq: Invalid cpufreq_tbl
To eliminate this undesired the effect, the patch changes SPEAr
driver to have it instantiated as a platform_driver. Then it will
only run on platforms that create the platform_device "spear-cpufreq".
This patch also creates platform node for SPEAr13xx boards.

The timer frequency of the arm_global_timer depends on the CPU
frequency. With cpufreq altering that frequency the arm_global_timer
does not maintain a stable time base. Therefore don't enable that timer
in case cpufreq is enabled.

On the newly introduced sama5d36, Gigabit and 10/100 Ethernet network
interfaces are probed in a different order than for the sama5d35.
Moreover, users are accustomed to this order in bootloaders and backports
for older kernel revisions.
So this patch switches DT node order as it is done for the other dual-Ethernet
sama5d3 SoC.
Better interface numbering which does not depend on DT node order is being
developed for stronger interface identification.

Select CONFIG_EMBEDDED as it it useful for that board.
Also select CONFIG_MTD_UBI to really enable UBIfs (CONFIG_FS_UBIFS depends on
it).

The defconfig for the at91sam9rl is quite old, refresh it:
- now uses EABI instead of OABI
- add devtmpfs support
- add UBI/UBIfs support
- remove a few config symbols that disappeared
