Wim Van Sebroeck 5ce9c371c7 watchdog: Use module_pci_driver
This patch converts the PCI watchdog drivers so that they use the
module_pci_driver() macro. This makes the code smaller and simpler.

Dave Mueller 8f90a3ae8f watchdog: sch311x_wdt.c: Remove RESGEN
The SCH311x chip contains 2 watchdogs. One is the watchdog programmable
by the runtime register at address 0x65-0x68, the other is the watchdog
inside the power on reset generator. This second watchdog has a fixed
timeout value of ~1.6 seconds and is configurable only by the RESGEN
register.

The BIOS normally takes care of the RESGEN watchdog and disables it (at
least) before the OS is booted.

Unfortunately the sch311x_wdt driver clears bit 0 of the RESGEN register
which has the effect that at the latest 1.6 seconds later, a POR is
triggered.

The attached patch fixes this problem by completely removing any
reference to the RESGEN watchdog from the sch311x_wdt driver.

Combine request_region and ioremap into devm_request_and_ioremap.  This has

Don Zickus 553222f3e8 x86/nmi: Add new NMI queues to deal with IO_CHK and SERR
In discussions with Thomas Mingarelli about hpwdt, he explained
to me some issues they were some when using their virtual NMI
button to test the hpwdt driver.

It turns out the virtual NMI button used on HP's machines do no
send unknown NMIs but instead send IO_CHK NMIs.  The way the
kernel code is written, the hpwdt driver can not register itself
against that type of NMI and therefore can not successfully
capture system information before panic'ing.

To solve this I created two new NMI queues to allow driver to
register against the IO_CHK and SERR NMIs.  Or in the hpwdt all
three (if you include unknown NMIs too).

The change is straightforward and just mimics what the unknown
NMI does.

Don Zickus 09ee101436 watchdog, hpwdt: Remove priority option for NMI callback
The NMI_UNKNOWN bucket only allows for one function to register
to it. The reason for that is because only functions which can
not determine if the NMI belongs to them or not should register
and would like to assume/swallow any NMI they see.

As a result it doesn't make sense to let more than one function
like this register.  In fact, letting a second function fail
allows us to know that more than one function is going to
swallow NMIs on the current system. This is better than silently
being ignored.

Therefore hpwdt's priority mechanism doesn't make sense any
more.  They will be always first on the NMI_UNKNOWN queue, if
they register.

Removing this parameter cleans up the code and simplifies things
for the next patch which changes how nmis are registered.

Pull "Disintegrate and delete asm/system.h" from David Howells:
 "Here are a bunch of patches to disintegrate asm/system.h into a set of
  separate bits to relieve the problem of circular inclusion
  dependencies.

  I've built all the working defconfigs from all the arches that I can
  and made sure that they don't break.

  The reason for these patches is that I recently encountered a circular
  dependency problem that came about when I produced some patches to
  optimise get_order() by rewriting it to use ilog2().

  This uses bitops - and on the SH arch asm/bitops.h drags in
  asm-generic/get_order.h by a circuituous route involving asm/system.h.

  The main difficulty seems to be asm/system.h.  It holds a number of
  low level bits with no/few dependencies that are commonly used (eg.
  memory barriers) and a number of bits with more dependencies that
  aren't used in many places (eg.  switch_to()).

  These patches break asm/system.h up into the following core pieces:

    (1) asm/barrier.h

        Move memory barriers here.  This already done for MIPS and Alpha.

    (2) asm/switch_to.h

        Move switch_to() and related stuff here.

    (3) asm/exec.h

        Move arch_align_stack() here.  Other process execution related bits
        could perhaps go here from asm/processor.h.

    (4) asm/cmpxchg.h

        Move xchg() and cmpxchg() here as they're full word atomic ops and
        frequently used by atomic_xchg() and atomic_cmpxchg().

    (5) asm/bug.h

        Move die() and related bits.

    (6) asm/auxvec.h

        Move AT_VECTOR_SIZE_ARCH here.

  Other arch headers are created as needed on a per-arch basis."

Fixed up some conflicts from other header file cleanups and moving code
around that has happened in the meantime, so David's testing is somewhat
weakened by that.  We'll find out anything that got broken and fix it..

necessarily have a 1 second resolution. So rather then have the core set

Linus Torvalds 5375871d43 Merge branch 'next' of git://git.kernel.org/pub/scm/linux/kernel/git/benh/powerpc
Pull powerpc merge from Benjamin Herrenschmidt:
 "Here's the powerpc batch for this merge window.  It is going to be a
  bit more nasty than usual as in touching things outside of
  arch/powerpc mostly due to the big iSeriesectomy :-) We finally got
  rid of the bugger (legacy iSeries support) which was a PITA to
  maintain and that nobody really used anymore.

  Here are some of the highlights:

   - Legacy iSeries is gone.  Thanks Stephen ! There's still some bits
     and pieces remaining if you do a grep -ir series arch/powerpc but
     they are harmless and will be removed in the next few weeks
     hopefully.

   - The 'fadump' functionality (Firmware Assisted Dump) replaces the
     previous (equivalent) "pHyp assisted dump"...  it's a rewrite of a
     mechanism to get the hypervisor to do crash dumps on pSeries, the
     new implementation hopefully being much more reliable.  Thanks
     Mahesh Salgaonkar.

   - The "EEH" code (pSeries PCI error handling & recovery) got a big
     spring cleaning, motivated by the need to be able to implement a
     new backend for it on top of some new different type of firwmare.

     The work isn't complete yet, but a good chunk of the cleanups is
     there.  Note that this adds a field to struct device_node which is
     not very nice and which Grant objects to.  I will have a patch soon
     that moves that to a powerpc private data structure (hopefully
     before rc1) and we'll improve things further later on (hopefully
     getting rid of the need for that pointer completely).  Thanks Gavin
     Shan.

   - I dug into our exception & interrupt handling code to improve the
     way we do lazy interrupt handling (and make it work properly with
     "edge" triggered interrupt sources), and while at it found & fixed
     a wagon of issues in those areas, including adding support for page
     fault retry & fatal signals on page faults.

   - Your usual random batch of small fixes & updates, including a bunch
     of new embedded boards, both Freescale and APM based ones, etc..."

I fixed up some conflicts with the generalized irq-domain changes from
Grant Likely, hopefully correctly.

Wim Van Sebroeck 0d098587ce watchdog: iTCO_wdt.c - problems with newer hardware due to SMI clearing (part 2)
Redhat Bugzilla: Bug 727875 - TCO_EN bit is disabled by TCO driver

The previous patch breaks reset watchdog behaviour on the older hardware.
It is therefor better to make sure that the behaviour for older hardware (<=ICH5 or
6300ESB) is preserved and that the behaviour for newer hardware is changed.
We therefor use the iTCO_version to see if we need the clearing of the SMI_TCO_EN
bit in the SMI_EN register.

So the new behaviour becomes:
turn_SMI_watchdog_clear_off=0 -> Do not turn off SMI clearing watchdog.
turn_SMI_watchdog_clear_off=1 -> Turn off SMI clearing watchdog when iTCO_version=1
				 (ICHO till ICH5 + 6300ESB only)
turn_SMI_watchdog_clear_off=2 -> Turn off SMI clearing watchdog.

Dmitry Artamonow 20403e845f watchdog: fix initialisation printout in s3c2410_wdt
Looks like a typo creeped in, and driver prints
s3c2410-wdt s3c2410-wdt: watchdog active, reset abled, irq abled

instead of
s3c2410-wdt s3c2410-wdt: watchdog active, reset enabled, irq enabled

Also it may completely disinform about irq status, as it prints
"irq enabled" when S3C2410_WTCON_INTEN is in fact 0.

Fix it.

Wim Van Sebroeck deb9197b70 watchdog: iTCO_wdt.c - problems with newer hardware due to SMI clearing
Redhat Bugzilla: Bug 727875 - TCO_EN bit is disabled by TCO driver
Jiri Slaby: 28d41f53f broke temperature sensors on a ICH10 chipset

The iTCO_wdt driver disables the SMI. This breaks good working of newer hardware.
The disabling of the SMI by the TCO logic dates back from the i810-tco driver
from Nils Faerber (around 28 July 2000). The reason for this was that some BIOSes
install handlers reset or disable the watchdog timer instead of resetting the system.
The trick to fix this was to disable the SMI (by clearing the SMI_TCO_EN bit of the
SMI_EN register) to prevent this from happening.

This however has strange effects on newer hardware. So we are in a situation that
a fix for broken old hardware affects newer hardware.

The correct solution is to make this fix an option (with the new module parameter:
turn_SMI_watchdog_clear_off) so that the default behaviour is the unfixed version.

the next patch will be to move this in the start and stop functions of the driver
and to add a new module parameter for the global_smi_en bit and to get rid of the
vendor_support code.

This fix can have an effect on old (typical ICH & ICH2 chipsets) motherboards that
have a broken BIOS implementation concerning TCO logic. In these case the module
parameter turn_SMI_watchdog_clear_off=1 will need to be added.

Venkat Subbiah 47bfd05813 watchdog: Octeon: Mark octeon_wdt interrupt as IRQF_NO_THREAD
This is to exclude it from force threading to allow RT patch set to work.

The watchdog timers are per-CPU and the addresses of register that reset
the timer are calculated based on the current CPU.  Therefore we cannot
allow it to run on a thread on a different CPU.  Also we only do a
single register write, which is much faster than scheduling a handler
thread.

And while on this line remove IRQF_DISABLED as this flag is a NOP.

Ingo's tree did the insane "add volatile to const array", which just

Don Zickus 9c48f1c629 x86, nmi: Wire up NMI handlers to new routines
Just convert all the files that have an nmi handler to the new routines.
Most of it is straight forward conversion.  A couple of places needed some
tweaking like kgdb which separates the debug notifier from the nmi handler
and mce removes a call to notify_die.

[Thanks to Ying for finding out the history behind that mce call

https://lkml.org/lkml/2010/5/27/114

And Boris responding that he would like to remove that call because of it

https://lkml.org/lkml/2011/9/21/163]

The things that get converted are the registeration/unregistration routines
and the nmi handler itself has its args changed along with code removal
to check which list it is on (most are on one NMI list except for kgdb
which has both an NMI routine and an NMI Unknown routine).

Add support for extra ioctl calls by adding a
ioctl watchdog operation. This operation will be
called before we do our own handling of ioctl
commands. This way we can override the internal
ioctl command handling and we can also add
extra ioctl commands. The ioctl watchdog operation
should return the appropriate error codes or
-ENOIOCTLCMD if the ioctl command should be handled
through the internal ioctl handling of the framework.

open, release and write functionality as defined in
the simplest watchdog API). Extra functionality will

Nick Bowler 081d83a339 watchdog: sp805: Flush posted writes in enable/disable.
There are no reads in these functions, so if MMIO writes are posted,
the writes in enable/disable may not have completed by the time these
functions return.  If the functions run from different CPUs, it's
in theory possible for the writes to be interleaved, which would be
disastrous for this driver.

At the very least, we need an mmiowb() before releasing the lock, but
since it seems desirable for the watchdog timer to be actually stopped
or reset when these functions return, read the lock register to force
the writes out.

Nick Bowler da3e515024 watchdog: sp805: Don't write 0 to the load value register.
At least on the Versatile Express' V2M, calling wdt_disable followed by
wdt_enable, for instance by running the following sequence:

  echo V > /dev/watchdog; echo V > /dev/watchdog

results in an immediate reset.  The wdt_disable function writes 0 to the
load register; while the watchdog interrupts are disabled at this point,
this special value is defined to trigger an interrupt immediately.  It
appears that in this instance, the reset happens when the interrupts
are subsequently enabled by wdt_enable.

Putting in a short delay after writing a new load value in wdt_enable
solves the issue, but it seems cleaner to simply never write 0 to the
load register at all: according to the hardware docs, writing 0 to the
control register suffices to stop the counter, and the write of 0 to
the load register is questionable anyway since this register resets to
0xffffffff.

Jonathan McDowell 7ccdb9467b watchdog: pc87413_wdt: Cleanup pc87413 watchdog driver to use
Inspired by Nat Gurumoorthy's recent patches for cleaning up the it87
drivers to use request_muxed_region for accessing the SuperIO area on
these chips, and the fact I have a GPIO driver for the pc8741x basically
ready for submission, here is a patch to cleanup the pc87413 watchdog
driver to use request_muxed_region for accessing the SuperIO area.

It also pulls out the details about the SWC IO area on initial driver
load, and properly does a request_region for that area - there's no
requirement to touch the SuperIO area after doing the initial watchdog
enable and IO base retrieval.

While I have hardware with a pc87413 on it it is not wired in a way that
allows the watchdog to reboot the machine, so I have not been able to
fully test these changes - I have checked that the driver correctly
initialises itself still and requests the SWC io region ok.

Nat Gurumoorthy a134b82560 watchdog: Use "request_muxed_region" in it87 watchdog drivers
Changes the it87 watchdog drivers to use "request_muxed_region".
Serialize access to the hardware by using "request_muxed_region" macro defined
by Alan Cox. Call to this macro will hold off the requestor if the resource is
currently busy. 

The use of the above macro makes it possible to get rid of
spinlocks in it8712f_wdt.c and it87_wdt.c watchdog drivers.
This also greatly simplifies the implementation of it87_wdt.c driver.

 "superio_enter" will return an error if call to "request_muxed_region" fails. 
Rest of the code change is to ripple an error return from superio_enter to
the top level.

Commit e391be76 (MIPS: Alchemy: Clean up GPIO registers and accessors)
changed the way the GPIO was toggled. Prior to this patch, we would
always actively drive the GPIO output to either 0 or 1, this patch
drove the GPIO active to 0, and put the GPIO in tristate to drive it
to 1, unfortunately this does not work, revert back to active driving.

Using a signed variable (gstate) to hold the gpio state and using a bit-
wise operation on it also resulted in toggling value from 1 to -2 since
the variable is signed. This value was then passed on to gpio_direction_
output, which always perform a if (value) ... to set the value to the
gpio, so we were always writing a 1 to this GPIO instead of 1 -> 0 -> 1 ...

Grant Likely b1608d69cb drivercore: revert addition of of_match to struct device
Commit b826291c, "drivercore/dt: add a match table pointer to struct
device" added an of_match pointer to struct device to cache the
of_match_table entry discovered at driver match time.  This was unsafe
because matching is not an atomic operation with probing a driver.  If
two or more drivers are attempted to be matched to a driver at the
same time, then the cached matching entry pointer could get
overwritten.

This patch reverts the of_match cache pointer and reworks all users to
call of_match_device() directly instead.

Peter Korsgaard d856b41846 watchdog: mpc8xxx_wdt: fix build
Since 1c48a5c93d (dt: Eliminate of_platform_{,un}register_driver)
mpc8xxx_wdt no longer builds as it tries to refer to a 'match' variable
rather than ofdev->dev.of_match that it checks just before.
