While unwinding backtrace, stack overflow is possible. This stack
overflow can sometimes lead to data abort in system if the area after
stack is not mapped to physical memory.
To prevent this problem from happening, execute the instructions that
can cause a data abort in separate helper functions, where a check for
feasibility is made before reading each word from the stack.

This patch moves bios32 over to using the generic code for enabling PCI
resources. Since the core code takes care of bridge resources too, we
can also drop the explicit IO and MEMORY enabling for them in the arch
code.
A side-effect of this change is that we no longer explicitly enable
devices when running in PCI_PROBE_ONLY mode. This stays closer to the
meaning of the option and prevents us from trying to enable devices
without any assigned resources (the core code refuses to enable
resources without parents).

Looking at perf profiles of multi-threaded hackbench runs, a significant
performance hit appears to manifest from the cmpxchg loop used to
implement the 32-bit atomic_add_unless function. This can be mitigated
by writing a direct implementation of __atomic_add_unless which doesn't
require iteration outside of the atomic operation.

Renames logical shift macros, 'push' and 'pull', defined in
arch/arm/include/asm/assembler.h, into 'lspush' and 'lspull'.
That eliminates name conflict between 'push' logical shift macro
and 'push' instruction mnemonic. That allows assembler.h to be
included in .S files that use 'push' instruction.

The pte_accessible macro can be used to identify page table entries
capable of being cached by a TLB. In principle, this differs from
pte_present, since PROT_NONE mappings are mapped using invalid entries
identified as present and ptes designated as `old' can use either
invalid entries or those with the access flag cleared (guaranteed not to
be in the TLB). However, there is a race to take care of, as described
in 20841405940e ("mm: fix TLB flush race between migration, and
change_protection_range"), between a page being migrated and mprotected
at the same time. In this case, we can check whether a TLB invalidation
is pending for the mm and if so, temporarily consider PROT_NONE mappings
as valid.
This patch implements a quick pte_accessible macro for ARM by simply
checking if the pte is valid/present depending on the mm. For classic
MMU, these checks are identical and will generate some false positives
for PROT_NONE mappings, but this is better than the current asm-generic
definition of ((void)(pte),1).
Finally, pte_present_user is moved to use pte_valid (and renamed
appropriately) since we don't care about cache flushing for faulting
mappings.

After a bunch of benchmarking on the interaction between dmb and pldw,
it turns out that issuing the pldw *after* the dmb instruction can
give modest performance gains (~3% atomic_add_return improvement on a
dual A15).
This patch adds prefetchw invocations to our barriered atomic operations
including cmpxchg, test_and_xxx and futexes.

DT nodes should be named according to the type of object that they
represent rather than the identity. DT nodes that contain a reg
property should include a unit address in their name. Fix these issues.
Add clock-output-names properties to the nodes so that the clocks get
named something meaningful. This works around the fact that the fixed
clock driver names clocks after the short node name, i.e. not including
the unit address.

During this release cycle, we're adding the new Armada 375, 380, and 385
SoCs. We're also migrating DT kirkwood boards into mach-mvebu. The
kirkwood changes make the different SoCs in mach-mvebu/ depend on
MULTI_V7 or MULTI_V5 as appropriate.
We add this dependency to the new SoCs so that when the branches are
merged, everything is as it should be.

This cleanup series gets rid of <mach/timex.h> for platforms not using
ARCH_MULTIPLATFORM. (For multi-platform code it's already unused since
387798b (ARM: initial multiplatform support).)
To make this work some code out of arch/arm needed to be adapted. The
respective changes got acks by their maintainers to be taken via armsoc
(with Andrew Morton substituting for Alessandro Zummo as rtc maintainer).
Compared to the previous pull request there was another patch added that
fixes a (non-critical) regression on ixp4xx. Olof Johansson asked to not
squash this fix into the original commit to save him from the need to
reverify the series.
