592913ecb8 time: Kill off CONFIG_GENERIC_TIME
Now that all arches have been converted over to use generic time via
clocksources or arch_gettimeoffset(), we can remove the GENERIC_TIME
config option and simplify the generic code.

86e4dd5add sh: support for platforms without PIO.
This extends some of the existing special casing for HAS_IOPORT
platforms and gets it to the point where platforms can begin to
conditionally select it.

The major changes here are that the PIO routines themselves go away
completely, including all of the machvec port mapping wrappers. With this
in place it's possible for any non-machvec abusing platform to disable
PIO completely. At present this is left as an opt-in until the abusers
are the odd ones out instead of the majority.

0102752e4c hw-breakpoints: Separate constraint space for data and instruction breakpoints
There are two outstanding fashions for archs to implement hardware
breakpoints.

The first is to separate breakpoint address pattern definition
space between data and instruction breakpoints. We then have
typically distinct instruction address breakpoint registers
and data address breakpoint registers, delivered with
separate control registers for data and instruction breakpoints
as well. This is the case of PowerPc and ARM for example.

The second consists in having merged breakpoint address space
definition between data and instruction breakpoint. Address
registers can host either instruction or data address and
the access mode for the breakpoint is defined in a control
register. This is the case of x86 and Super H.

This patch adds a new CONFIG_HAVE_MIXED_BREAKPOINTS_REGS config
that archs can select if they belong to the second case. Those
will have their slot allocation merged for instructions and
data breakpoints.

The others will have a separate slot tracking between data and
instruction breakpoints.

37feecb0ae sh: Disable generic IRQ probing.
IRQ autoprobing hasn't actually worked for us at all since very early in
2.6, but no one seems to have noticed given that none of the drivers
that use it see much testing.

yenta_socket is the odd one out, and that depends on PCI IRQs which are
fixed on all SH platforms anyways. Consequently, turning off autoprobing
fixes up crashes triggered by yenta_socket and at least gets it working
again on r7785rp.

6d63e73d52 sh: Limit ioremap_prot() to 32bit pgprot parts.
Presently ioremap_prot() uses an unsigned long to pass the pgprot value
around. This results in the upper half of the pgprot being chomped when
using 64-bit pgprots on a 32-bit ABI (X2TLB and SH-5).

As the only users of ioremap_prot() are presently legacy parts, this
doesn't cause too much of an issue. In the future when the interface is
converted to use pgprot_t directly this can be re-enabled for the other
parts, too.

ee2760ea58 sh: default to sparseirq.
As SH has a very sparse IRQ map by default, all new CPUs and boards
benefit from using sparseirq by default. Despite this, there are still a
few stragglers (mostly due to using a fixed IRQ range for their FPGA
IRQ mappings), and these still need to be converted over one by one. As
these are now in the minority, and we do not want to encourage this sort
of brain-damage in newer board ports, we force sparseirq on.

8152a74bc0 sh: Only provide a PCLK definition for legacy CPG CPUs.
As CPUs are migrated over to more fully-featured clock frameworks of
their own and off of the legacy CPG code, they no longer have any real
need for defining the PCLK value. The PCLK define in itself is already
fairly misleading, as many boards get their input clocks from different
sources, making this value fairly arbitrary anyways.

Outside of the legacy CPG clock framework, the only place where this
value is used is for deriving CLOCK_TICK_RATE, which we set back to the
legacy PIT value that it was before the PCLK definitions were added in
the first place.

As SH-3 doesn't support variable page sizes, we tighten up the

cdd6c482c9 perf: Do the big rename: Performance Counters -> Performance Events
Bye-bye Performance Counters, welcome Performance Events!

In the past few months the perfcounters subsystem has grown out its
initial role of counting hardware events, and has become (and is
becoming) a much broader generic event enumeration, reporting, logging,
monitoring, analysis facility.

Naming its core object 'perf_counter' and naming the subsystem
'perfcounters' has become more and more of a misnomer. With pending
code like hw-breakpoints support the 'counter' name is less and
less appropriate.

All in one, we've decided to rename the subsystem to 'performance
events' and to propagate this rename through all fields, variables
and API names. (in an ABI compatible fashion)

The word 'event' is also a bit shorter than 'counter' - which makes
it slightly more convenient to write/handle as well.

Thanks goes to Stephane Eranian who first observed this misnomer and
suggested a rename.

User-space tooling and ABI compatibility is not affected - this patch
should be function-invariant. (Also, defconfigs were not touched to
keep the size down.)

This patch has been generated via the following script:

  FILES=$(find * -type f | grep -vE 'oprofile|[^K]config')

  sed -i \
    -e 's/PERF_EVENT_/PERF_RECORD_/g' \
    -e 's/PERF_COUNTER/PERF_EVENT/g' \
    -e 's/perf_counter/perf_event/g' \
    -e 's/nb_counters/nb_events/g' \
    -e 's/swcounter/swevent/g' \
    -e 's/tpcounter_event/tp_event/g' \
    $FILES

  for N in $(find . -name perf_counter.[ch]); do
    M=$(echo $N | sed 's/perf_counter/perf_event/g')
    mv $N $M
  done

  FILES=$(find . -name perf_event.*)

  sed -i \
    -e 's/COUNTER_MASK/REG_MASK/g' \
    -e 's/COUNTER/EVENT/g' \
    -e 's/\<event\>/event_id/g' \
    -e 's/counter/event/g' \
    -e 's/Counter/Event/g' \
    $FILES

... to keep it as correct as possible. This script can also be
used by anyone who has pending perfcounters patches - it converts
a Linux kernel tree over to the new naming. We tried to time this
change to the point in time where the amount of pending patches
is the smallest: the end of the merge window.

Namespace clashes were fixed up in a preparatory patch - and some
stylistic fallout will be fixed up in a subsequent patch.

( NOTE: 'counters' are still the proper terminology when we deal
  with hardware registers - and these sed scripts are a bit
  over-eager in renaming them. I've undone some of that, but
  in case there's something left where 'counter' would be
  better than 'event' we can undo that on an individual basis
  instead of touching an otherwise nicely automated patch. )

ac2c596b57 sh: let ARCH_SHMOBILE select PM and PM_RUNTIME

enable clocks to the Runtime PM enabled hardware blocks.
This patch makes Runtime PM mandatory on SuperH Mobile.
