When building a kernel with support for both ARMv6 and ARMv7 but
no MMU, the call from tauros2_internal_init to adjust_cr causes
a link error. While that could probably be resolved, we don't
actually support cache-tauros2 on ARMv6 any more. All PJ4 CPU
implementations support both ARMv6 and ARMv7 and we already assume
that we are using them only in ARMv7 mode.
Removing the ARMv6 code path reduces the code size and avoids
the linker error.

Moxart uses an FA526 CPU core, which is ARMv4 based, not ARMv4T.
Before moxart, we had no CONFIG_MULTI_V4 option, since no ARMv4 platform
was enabled for multiplatform. This now adds the missing option, which
will give us slightly more efficient code on pure moxart kernels,
because we can build a pure FA526 kernel now rather than a combined
FA526+ARM920T kernel that we used to.

The s5p64x0 platform supports two distinct SoCs, s5p6440 and s5p6450,
and in the normal configuration, both are enabled. However if we build
a kernel that only enables one of the two, the #ifdef logic in common.c
breaks down, as some of the functions declared in the header are defined
to NULL using the preprocessor but then defined anyway.
This patch cleans up the mess and ensures that each function has either
exactly one C declaration and one matching C definition, or we have
a NULL defined function pointer but no C definition.

Building the integrator platform without TTY support currently
results in a build failure because we always turn on the
pl010 or pl011 drivers. Changing this to a conditional 'select'
statement enables us to build more random configurations, although
it should have little impact for practical configurations.

Commit b713aa0b15 "ARM: fix asm/memory.h build error" broke some
configurations on mach-realview with sparsemem enabled, which
is missing a definition of PHYS_OFFSET:
arch/arm/include/asm/memory.h:268:42: error: 'PHYS_OFFSET' undeclared (first use in this function)
#define PHYS_PFN_OFFSET ((unsigned long)(PHYS_OFFSET >> PAGE_SHIFT))
arch/arm/include/asm/dma-mapping.h:104:9: note: in expansion of macro 'PHYS_PFN_OFFSET'
return PHYS_PFN_OFFSET + dma_to_pfn(dev, *dev->dma_mask);
An easy workaround is for realview to define PHYS_OFFSET itself,
in the same way we define it for platforms that don't have a private
__virt_to_phys function.

The global screen_info structure is used to communicate

The trizeps4 and trizeps4wl platforms are both implemented
using the same board file. Since the trizeps4wl code is a
superset of trizeps4, it makes no sense to enable just the
latter, but with the current Kconfig logic, it causes the
board file not to be built at all.

The code for h2 and osk implicitly assumes that the tps65010

This is fine for most real uses, but it does get into the way

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.

Set 'ti,set-rate-parent' property for clocks in the dpll4_m4 clock
path, which is used for DSS functional clock. This fixes DSS driver's
clock rate configuration, which needs the rate to be propagated properly
to the divider node (dpll4_m4_ck).

We need to use set-rate-parent for dpll4_m4 clock path, so use the
ti,fixed-factor-clock version which supports set-rate-parent property.
The set-rate-parent flag itself is set in the following patch, this one
just changes the clock driver to ti,fixed-factor-clock without any other
changes.

OMAP3630 DPLL4 is different than on OMAP3430, in that it doesn't have
the x2 multiplier for its outputs. This is not currently reflected in
the clock DT data.
Fix the issue by setting the clock multiplier to 1 (instead of 2) for the
DPLL4 output clocks.

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.

Using Rabin Vincent's ARM uprobes patches as a base, enable uprobes
support on ARM.
Caveats:
- Thumb is not supported

Because the common underlying code for ARM kprobes and uprobes needs
to share a common architecrure-specific context structure, and because
the generic kprobes include file insists on defining this to a dummy
structure when kprobes is not configured, a new common structure is
required which can exist when uprobes is configured without kprobes.
In this case kprobes will define a dummy structure, but without the
define aliasing the two structure tags it will not affect uprobes and
the shared probes code.

Any more ARM kprobes/uprobes symbols which have "kprobe" in the name must be
changed to the more generic "probes" or other non-kprobes specific symbol.

Change kprobe_emulate_none, kprobe_simulate_nop, and arm_kprobe_decode_init
function names to something more appropriate for code being shared
outside of the kprobes subsystem. Also, move the new arm_probes_decode_init
declaration out of the kprobes.h include file and into the probes.h include file.
