Tejun Heo 5a0e3ad6af include cleanup: Update gfp.h and slab.h includes to prepare for breaking implicit slab.h inclusion from percpu.h
percpu.h is included by sched.h and module.h and thus ends up being
included when building most .c files.  percpu.h includes slab.h which
in turn includes gfp.h making everything defined by the two files
universally available and complicating inclusion dependencies.

percpu.h -> slab.h dependency is about to be removed.  Prepare for
this change by updating users of gfp and slab facilities include those
headers directly instead of assuming availability.  As this conversion
needs to touch large number of source files, the following script is
used as the basis of conversion.

  http://userweb.kernel.org/~tj/misc/slabh-sweep.py

The script does the followings.

* Scan files for gfp and slab usages and update includes such that
  only the necessary includes are there.  ie. if only gfp is used,
  gfp.h, if slab is used, slab.h.

* When the script inserts a new include, it looks at the include
  blocks and try to put the new include such that its order conforms
  to its surrounding.  It's put in the include block which contains
  core kernel includes, in the same order that the rest are ordered -
  alphabetical, Christmas tree, rev-Xmas-tree or at the end if there
  doesn't seem to be any matching order.

* If the script can't find a place to put a new include (mostly
  because the file doesn't have fitting include block), it prints out
  an error message indicating which .h file needs to be added to the
  file.

The conversion was done in the following steps.

1. The initial automatic conversion of all .c files updated slightly
   over 4000 files, deleting around 700 includes and adding ~480 gfp.h
   and ~3000 slab.h inclusions.  The script emitted errors for ~400
   files.

2. Each error was manually checked.  Some didn't need the inclusion,
   some needed manual addition while adding it to implementation .h or
   embedding .c file was more appropriate for others.  This step added
   inclusions to around 150 files.

3. The script was run again and the output was compared to the edits
   from #2 to make sure no file was left behind.

4. Several build tests were done and a couple of problems were fixed.
   e.g. lib/decompress_*.c used malloc/free() wrappers around slab
   APIs requiring slab.h to be added manually.

5. The script was run on all .h files but without automatically
   editing them as sprinkling gfp.h and slab.h inclusions around .h
   files could easily lead to inclusion dependency hell.  Most gfp.h
   inclusion directives were ignored as stuff from gfp.h was usually
   wildly available and often used in preprocessor macros.  Each
   slab.h inclusion directive was examined and added manually as
   necessary.

6. percpu.h was updated not to include slab.h.

7. Build test were done on the following configurations and failures
   were fixed.  CONFIG_GCOV_KERNEL was turned off for all tests (as my
   distributed build env didn't work with gcov compiles) and a few
   more options had to be turned off depending on archs to make things
   build (like ipr on powerpc/64 which failed due to missing writeq).

   * x86 and x86_64 UP and SMP allmodconfig and a custom test config.
   * powerpc and powerpc64 SMP allmodconfig
   * sparc and sparc64 SMP allmodconfig
   * ia64 SMP allmodconfig
   * s390 SMP allmodconfig
   * alpha SMP allmodconfig
   * um on x86_64 SMP allmodconfig

8. percpu.h modifications were reverted so that it could be applied as
   a separate patch and serve as bisection point.

Given the fact that I had only a couple of failures from tests on step
6, I'm fairly confident about the coverage of this conversion patch.
If there is a breakage, it's likely to be something in one of the arch
headers which should be easily discoverable easily on most builds of
the specific arch.

IXP4xx CPUs can indirectly access the whole 4 GB PCI MMIO address space (using
the non-prefetch registers). Previously the available space depended on the CPU
variant, since one of the IXP43x platforms needed more than the usual 128 MB.

Mikael Pettersson 74c32e7234 ixp4xx: arch_idle() documentation fixup
The body of the mach-ixp4xx arch_idle() is mysteriously
disabled by an #if 0 .. #endif. Normally one would expect
to find a call to cpu_do_idle() there, but that call is
disabled, even though cpu_do_idle() is implemented for
XScale cores (and ixp4xx is one).

The explanation can be found in the ixp42x developer's manual
which states that the XScale core clock and power management
registers aren't implemented on ixp42x [3.5.2.2].

Also, the disabled code has suffered from bit rot:
- it checks hlt_counter which is obsolete, as that variable
  and all related code now is private to kernel/process.c
- it passes too many parameters to cpu_do_idle()

So this patch:
- adds a comment before the #if 0 to explain why
  cpu_do_idle() mustn't be called on ixp4xx
- removes the obsolete test of hlt_counter and the
  obsolete parameter to cpu_do_idle()

This is purely a documentation fixup and changes no
generated code. Even so, it has been tested on an
ixp420 machine (ds101).

Mikael Pettersson ceb69a899f ixp4xx: timer and clocks cleanups
This patch does a few simple cleanups of the ixp4xx timer
and clocksource/clockevent code in mach-ixp4xx/common.c:

- ixp4xx_clocksource_init() is static and always returns 0,
  which is ignored by its only caller: make it return void
- ixp4xx_clockevent_init(): ditto
- ixp4xx_get_cycles() is only referenced locally: make it static
- use the ixp4xx_timer_irq.dev_id field to pass &clockevent_ixp4xx
  to ixp4xx_timer_interrupt() via its dev_id parameter, allowing
  the code in ixp4xx_timer_interrupt() to be smaller and faster

Krzysztof Halasa 5dbc46506a IXP42x HSS support for setting internal clock rate
HSS usually uses external clocks, so it's not a big deal. Internal clock
is used for direct DTE-DTE connections and when the DCE doesn't provide
it's own clock.

This also depends on the oscillator frequency. Intel seems to have
calculated the clock register settings for 33.33 MHz (66.66 MHz timer
base). Their settings seem quite suboptimal both in terms of average
frequency (60 ppm is unacceptable for G.703 applications, their primary
intended usage(?)) and jitter.

Many (most?) platforms use a 33.333 MHz oscillator, a 10 ppm difference
from Intel's base.

Instead of creating static tables, I've created a procedure to program
the HSS clock register. The register consists of 3 parts (A, B, C).
The average frequency (= bit rate) is:
66.66x MHz / (A  + (B + 1) / (C + 1))
The procedure aims at the closest average frequency, possibly at the
cost of increased jitter. Nobody would be able to directly drive an
unbufferred transmitter with a HSS anyway, and the frequency error is
what it really counts.

I've verified the above with an oscilloscope on IXP425. It seems IXP46x
and possibly IXP43x use a bit different clock generation algorithm - it
looks like the avg frequency is:
(on IXP465) 66.66x MHz / (A  + B / (C + 1)).
Also they use much greater precomputed A and B - on IXP425 it would
simply result in more jitter, but I don't know how does it work on
IXP46x (perhaps 3 least significant bits aren't used?).

Anyway it looks that they were aiming for exactly +60 ppm or -60 ppm,
while <1 ppm is typically possible (with a synchronized clock, of
course).

The attached patch makes it possible to set almost any bit rate
(my IXP425 533 MHz quits at > 22 Mb/s if a single port is used, and the
minimum is ca. 65 Kb/s).

This is independent of MVIP (multi-E1/T1 on one HSS) mode.

Every arch except arm's ixp4xx defines IO_SPACE_LIMIT as an all-bits-one
bitmask, typically -1UL but sometimes only a 16-bit 0x0000ffff. But ixp4xx
defines it as 0xffff0000, which is now causing the PCI failures.

Russell King noted that ixp4xx has 64KB PCI IO space, so IO_SPACE_LIMIT
should be 0x0000ffff. This patch makes that change, which fixes the PCI
failures on my ixp4xx box.

Russell King be093beb60 [ARM] pass reboot command line to arch_reset()
OMAP wishes to pass state to the boot loader upon reboot in order to
instruct it whether to wait for USB-based reflashing or not.  There is
already a facility to do this via the reboot() syscall, except we ignore
the string passed to machine_restart().

This patch fixes things to pass this string to arch_reset().  This means
that we keep the reboot mode limited to telling the kernel _how_ to
perform the reboot which should be independent of what we request the
boot loader to do.

Russell King dcea83adc6 [ARM] Hide ISA DMA API when ISA_DMA_API is unset
When ISA_DMA_API is unset, we're not implementing the ISA DMA API,
so there's no point in publishing the prototypes via asm/dma.h, nor
including the machine dependent parts of that API.

This allows us to remove a lot of mach/dma.h files which don't contain
any useful code.  Unfortunately though, some platforms put their own
private non-ISA definitions into mach/dma.h, so we leave these behind
and fix the appropriate #include statments.

Let's provide an overridable default instead of having every machine
class define __virt_to_bus and __bus_to_virt to the same thing.  What
most platforms are using is bus_addr == phys_addr so such is the default.

One exception is ebsa110 which has no DMA what so ever, so the actual
definition is not important except only for proper compilation.  Also
added a comment about the special footbridge bus translation.

Let's also remove comments alluding to set_dma_addr which is not

Rod Whitby 2bea80187f [ARM] 4769/2: ixp4xx: Button updates for the dsmg600 board
* Remove the superfluous declaration of ctrl_alt_del().
 * Convert GPIO and IRQ handling to use the <asm/gpio.h> api.
 * Perform the reset on the release of the power button, so that
   NAS devices which have been set to auto-power-on (by solder
   bridging the power button) do not continuously power cycle.

Thomas Gleixner 18de5bc4c1 clockevents: fix resume logic
We need to make sure, that the clockevent devices are resumed, before
the tick is resumed. The current resume logic does not guarantee this.

Add CLOCK_EVT_MODE_RESUME and call the set mode functions of the clock
event devices before resuming the tick / oneshot functionality.

Fixup the existing users.

Thanks to Nigel Cunningham for tracking down a long standing thinko,
which affected the jinxed VAIO.
