Add pci-common.h and pci32.c. Files are based on PPC version.
There are removed ppc specific parts and the code was completely
clean.

I removed PPC_ prefix from constants
Removed ppc64 specifis parts

I need to use generic/iomap.h for PCI that's why is necessary
to include it and fix ioport_{map,unmap} functions.

Support function for PCI. We don't use any advance mapping mechanism
that's why implementation is simple.

Add DMA support for Microblaze. There are some part of this new feature:
1. Basic DMA support
2. Enable DMA debug option
3. Setup notifier
Ad 1. dma-mapping come from powerpc and x86 version and it is based on
generic dma-mapping-common.h
Ad 2. DMA support debug features which is used in generic file.
For more information please look at Documentation/DMA-API.txt
Ad 3. notifier is very important to setup dma_ops. Without this part
for example ll_temac driver failed because there are no setup dma operations.

Events that trigger overflows by interrupting a context can
use get_irq_regs() or task_pt_regs() to retrieve the state
when the event triggered. But this is not the case for some
other class of events like trace events as tracepoints are
executed in the same context than the code that triggered
the event.
It means we need a different api to capture the regs there,
namely we need a hot snapshot to get the most important
informations for perf: the instruction pointer to get the
event origin, the frame pointer for the callchain, the code
segment for user_mode() tests (we always use __KERNEL_CS as
trace events always occur from the kernel) and the eflags
for further purposes.
v2: rename perf_save_regs to perf_fetch_caller_regs as per
Masami's suggestion.

We were using the frame pointer based stack walker on every
contexts in x86-32, but not in x86-64 where we only use the
seven-league boots on the exception stacks.
Use it also on irq and process stacks. This utterly accelerate
the captures.

hw_perf_enable() would enable already enabled events.
This causes problems with code that assumes that ->enable/->disable calls
are balanced (like the LBR code does).
What happens is that events that were already running and left in place
would get enabled again.
Avoid this by only enabling new events that match their previous
assignment.

hw_perf_enable() would disable events that were not yet enabled.
This causes problems with code that assumes that ->enable/->disable calls
are balanced (like the LBR code does).
What happens is that we disable newly added counters that match their
previous assignment, even though they are not yet programmed on the
hardware.
Avoid this by only doing the first pass over the existing events.

Calling ioctl(PERF_EVENT_IOC_DISABLE) on a thottled counter would result
in a double disable, cure this by using x86_pmu_{start,stop} for
throttle/unthrottle and teach x86_pmu_stop() to check ->active_mask.

Remove the hw_perf_event_*() hotplug hooks in favour of per PMU hotplug
notifiers. This has the advantage of reducing the static weak interface
as well as exposing all hotplug actions to the PMU.
Use this to fix x86 hotplug usage where we did things in ONLINE which
should have been done in UP_PREPARE or STARTING.

This makes it easier to extend perf_sample_data and fixes a bug on arm
and sparc, which failed to set ->raw to NULL, which can cause crashes
when combined with PERF_SAMPLE_RAW.
It also optimizes PowerPC and tracepoint, because the struct
initialization is forced to zero out the whole structure.

This fixes up some of the I/D/F clock ambiguity in the sh-sci driver.
The interface clock in most cases just wraps back to the peripheral
clock, while the function clock wraps in to the MSTP bits. As the logic
was somewhat inverted, this cleans that up, and also enables all CPUs
with SCI MSTP bits to match function clocks through clkdev lookup.
As a result, this gets rid of the clk string abuse on the sh side, and
the clock string will be killed off once the ARM code has had a chance to
sync up. This also enables MSTP gating on CPUs like 7786 which had never
wired it up before. Impacted CPUs are primarily all SH-Mobiles, SH7785,
and SH7786.

The on-chip keypad peripheral requires different registers to be setup
depending on the standby type (standby vs hibernation). However, since
the power management framework doesn't differentiate between these types,
the driver doesn't know which registers to program and subsequently it
avoids doing so.
Always enabling the keyboard wakeup source causes misbehavior when the
pins are not assigned to the keypad. If they happen to drive a certain
level, they'll trigger a wake up event which is not wanted. So until
the aforementioned issue can be sorted out, drop support for the
wakeup source completely.

This patch provides infrastructure for MAC Wake-On-Lan and PHYINT use in
phylib. New Interrupts added:
IRQ_MAC_PHYINT /* PHY_INT Interrupt */
IRQ_MAC_MMCINT /* MMC Counter Interrupt */
IRQ_MAC_RXFSINT /* RX Frame-Status Interrupt */
IRQ_MAC_TXFSINT /* TX Frame-Status Interrupt */
IRQ_MAC_WAKEDET /* Wake-Up Interrupt */
IRQ_MAC_RXDMAERR /* RX DMA Direction Error Interrupt */
IRQ_MAC_TXDMAERR /* TX DMA Direction Error Interrupt */
IRQ_MAC_STMDONE /* Station Mgt. Transfer Done Interrupt */
On BF537/6 the implementation is not straight forward since there are now
two chained chained_handlers. A cleaner approach would have been to add
latter IRQs to the demux of IRQ_GENERIC_ERROR.
