Most of the warnings emitted (we fail arch/sparc file
builds with -Werror) were legitimate but harmless, however
one case (n2_pcr_write) was a genuine bug.

A recent patch to the x86 randomization code caused me to take
a quick look at what we do on sparc64, and in doing so I noticed
that we sometimes calculate a non-page-aligned randomization value
and stick it into mmap_base.
I also noticed that since I copied the logic over from PowerPC,
the powerpc code has tweaked the randomization ranges in ways that
would benefit us as well.
For one thing, we should allow up to at least 8MB of randomization
otherwise huge-page regions when HPAGE_SIZE is 4MB never randomize
at all.
And on the 64-bit side we were using up to 4GB. Tone it down to
1GB as 4GB can result in a lot of address space wastage.
Finally, make sure all computations are unsigned.

Support for Always Running APIC timer (ARAT) was introduced in
commit db954b5898. This feature
allows us to avoid switching timers from LAPIC to something else
(e.g. HPET) and go into timer broadcasts when entering deep
C-states.
AMD processors don't provide a CPUID bit for that feature but
they also keep APIC timers running in deep C-states (except for
cases when the processor is affected by erratum 400). Therefore
we should set ARAT feature bit on AMD CPUs.

Intel Archiecture Software Developer's Manual section 7.1.3 specifies that a
core serializing instruction such as "cpuid" should be executed on _each_ core
before the new instruction is made visible.
Failure to do so can lead to unspecified behavior (Intel XMC erratas include
General Protection Fault in the list), so we should avoid this at all cost.
This problem can affect modified code executed by interrupt handlers after
interrupt are re-enabled at the end of stop_machine, because no core serializing
instruction is executed between the code modification and the moment interrupts
are reenabled.
Because stop_machine_text_poke performs the text modification from the first CPU
decrementing stop_machine_first, modified code executed in thread context is
also affected by this problem. To explain why, we have to split the CPUs in two
categories: the CPU that initiates the text modification (calls text_poke_smp)
and all the others. The scheduler, executed on all other CPUs after
stop_machine, issues an "iret" core serializing instruction, and therefore
handles core serialization for all these CPUs. However, the text modification
initiator can continue its execution on the same thread and access the modified
text without any scheduler call. Given that the CPU that initiates the code
modification is not guaranteed to be the one actually performing the code
modification, it falls into the XMC errata.
Q: Isn't this executed from an IPI handler, which will return with IRET (a
serializing instruction) anyway?
A: No, now stop_machine uses per-cpu workqueue, so that handler will be
executed from worker threads. There is no iret anymore.

The MUSB driver doesn't see its platform device on DM644x EVM board anymore
since commit 73b089b052 (usb: musb: split davinci
to its own platform_driver) because the new probe is called as subsys_initcall()
now, and the device is registered later than that by the board code. Move the
registration to davinci_evm_init() -- it's safe to do so because the MUSB core
device still gets initialized as fs_initcall() -- which is late enough for the
I2C GPIO expander (which controls VBUS) to be initialized.

This patch includes the implementation of the clock gating
for System MMU. Initially, all System MMUs are not asserted
the system clock. Asserting the system clock to a System MMU
is enabled only when s5p_sysmmu_enable() is called. Likewise,
it is disabled only when s5p_sysmmu_disable() is called.
Therefore, clock gating on System MMUs are still invisible to
the outside of the System MMU driver.

The reality is that you do not need the abiltity to configure the
clock divider for ColdFire CPUs. It is a fixed ratio on any given
ColdFire family member. It is not the same for all ColdFire parts,
but it is always the same in a model range. So hard define the divider
for each supported ColdFire CPU type and remove the Kconfig option.

The intc-simr interrupt controller on some ColdFire CPUs has a set range of
interrupts its supports (64 through 128 or 192 depending on model). We
shouldn't be setting this handler for every possible interrupt from 0 to
255. Set more appropriate limits, and this means we can drop the interrupt
number check in the mask and unmask routines.

Use a proper irq_startup() routine to intialize the interrupt priority
and level register in the ColdFire intc-2 controller code. We shouldn't
be checking if the priority/level has been set on every unmask operation.

The FireBee is a ColdFire 5475 based board. Add a configuration option
to support it, and the basic platform flash layout code.

Most ColdFire CPUs have an internal peripheral set that can be mapped at
a user selectable address. Different ColdFire parts either use an MBAR
register of an IPSBAR register to map the peripheral region. Most boards
use the Freescale default mappings - but not all.
Make the setting of the MBAR or IPSBAR register configurable. And only make
the selection available on the appropriate ColdFire CPU types.
