Will Deacon d4c7b1f9b4 ARM: 6470/1: atomic64: use generic implementation for OABI configurations
The old apcs-gnu ABI doesn't guarantee that double words are allocated
to registers with even alignment, causing the 64-bit exclusive memory
operations to be rejected by the assembler.

This patch requires that CONFIG_AEABI is set in order to use the native
atomic operations and falls back to the generic (spinlock) code otherwise.

Peter Zijlstra e360adbe29 irq_work: Add generic hardirq context callbacks
Provide a mechanism that allows running code in IRQ context. It is
most useful for NMI code that needs to interact with the rest of the
system -- like wakeup a task to drain buffers.

Perf currently has such a mechanism, so extract that and provide it as
a generic feature, independent of perf so that others may also
benefit.

The IRQ context callback is generated through self-IPIs where
possible, or on architectures like powerpc the decrementer (the
built-in timer facility) is set to generate an interrupt immediately.

Architectures that don't have anything like this get to do with a
callback from the timer tick. These architectures can call
irq_work_run() at the tail of any IRQ handlers that might enqueue such
work (like the perf IRQ handler) to avoid undue latencies in
processing the work.

Russell King f00ec48fad ARM: Allow SMP kernels to boot on UP systems
UP systems do not implement all the instructions that SMP systems have,
so in order to boot a SMP kernel on a UP system, we need to rewrite
parts of the kernel.

Do this using an 'alternatives' scheme, where the kernel code and data
is modified prior to initialization to replace the SMP instructions,
thereby rendering the problematical code ineffectual.  We use the linker
to generate a list of 32-bit word locations and their replacement values,
and run through these replacements when we detect a UP system.

Peter Korsgaard 79e27dc067 ARM: 6400/1: at91: fix arch_gettimeoffset fallout
5cfc8ee0bb (ARM: convert arm to arch_gettimeoffset()) marked all of
at91 AND at91x40 as needing ARCH_USES_GETTIMEOFFSET, and hence no high
res timer support / accurate clock_gettime() - But only at91x40 needs it.

Hans J. Koch 83ef3338a2 ARM: Introduce plat-tcc
This patch introduces support for the tcc platform by creating an
arch/arm/plat-tcc and arch/arm/mach-tcc8k directories and adding
basic include files plus Kconfig and Makefile.

Will Deacon a672e99b12 ARM: 6389/1: errata: incorrect hazard handling in the SCU may lead to data corruption
On the r2p0, r2p1 and r2p2 versions of the Cortex-A9, data corruption
can occur if a shared cache line is replaced on one CPU as another CPU
is accessing it.

This workaround sets two bits in the diagnostic register of the Cortex-A9,
reducing the linefill issuing capabilities of the processor and
avoiding the erroneous behaviour.

Will Deacon 9f05027c7c ARM: 6388/1: errata: DMB operation may be faulty
On versions of the Cortex-A9 up to and including r2p2, under rare
circumstances, a DMB instruction between 2 write operations may not
ensure the correct visibility ordering of the 2 writes.

This workaround sets a bit in the diagnostic register of the Cortex-A9,
causing the DMB instruction to behave like a DSB, which functions
correctly on the affected cores.

Russell King 9e84ed63dc ARM: Partially revert "Auto calculate ZRELADDR and provide option for exceptions"
Partially revert e69edc7, which introduced automatic zreladdr
support.  The change in the way the manual definition is defined
seems to be error and conflict prone.  Go back to the original way
we were handling this for the time being, while keeping the automatic
zreladdr facility.
