Linus Torvalds 5d4e2d08e7 Driver core pull for 3.5-rc1
Here's the driver core, and other driver subsystems, pull request for
 the 3.5-rc1 merge window.
 
 Outside of a few minor driver core changes, we ended up with the
 following different subsystem and core changes as well, due to
 interdependancies on the driver core:
  - hyperv driver updates
  - drivers/memory being created and some drivers moved into it
  - extcon driver subsystem created out of the old Android staging switch
    driver code
  - dynamic debug updates
  - printk rework, and /dev/kmsg changes
 
 All of this has been tested in the linux-next releases for a few weeks
 with no reported problems.

Rusty Russell 90ab5ee941 module_param: make bool parameters really bool (drivers & misc)
module_param(bool) used to counter-intuitively take an int.  In
fddd5201 (mid-2009) we allowed bool or int/unsigned int using a messy
trick.

It's time to remove the int/unsigned int option.  For this version
it'll simply give a warning, but it'll break next kernel version.

Jiri Kosina 9fdbdd062b parport_pc: release IO region properly if unsupported ITE887x card is found
sio_ite_8872_probe() bails out if it detects no-parallel (1S, 2S) or
unknown card.

It doesn't call release_region() on the previously allocated resource
though.  This causes

  (a) leak of the resource
  (b) kernel oops when parport module is removed and /proc/ioports is read. This
      is because the string that has been associated to the IO port region
      is a static char array inside the already removed module.

Let's call release_region() properly before baling out.

Timedia/SUNIX PCI cards with both serial and parallel ports are
currently supported by 8250_pci and parport_pc individually.  Moving
that support into parport_serial allows using both types of ports at the
same time.

Nicos Gollan 7808edcd30 Basic support for Moschip 9900 family I/O chips
Add I/O based support for serial and parallel ports of the following
chips:

Vendor: Moschip (0x9710)

Parts (device IDs)
* 9900 (0x9900)
* 9904 (0x9904
* 9901 (0x9912, also sold as 9912)
* 9922 (0x9922)

On all chips but the 9900, a single port is provided per PCI subdevice
(subvendor-ID 0xA000, subdevice-IDs 0x1000 for serial, 0x2000 for
parallel with proper class codes). In cascading configurations, the
9900 provides two devices per subdevice, with subvendor-ID 0xA000 and
subdevice-IDs 0x30ps where p is the number of parallel ports and s the
number of serial ports.

Basic testing was only done on the serial part of a 9912 to the point
where it can be used for a serial kernel console, and advanced features
are completely untested. It is possible to reduce functionality of the
chips by adding a configuration EEPROM, and the datasheet [1] is
inconsistent w.r.t subdevices in the 4s+2s1p and 2s1p+4s
configurations. The subdevice-ID 0x3012 should likely read 0x3011 with
a serial port in function 3, which would be consistent with the BAR
layouts. For now, the drivers ignore subdevices with ID 0x1000 and no
class code.

The parallel ports are integrated in parport_serial even for purely
parallel parts to reduce the footprint of the patch.

Alexander Gordeev cbeb4b7ad5 parport: make lockdep happy with waitlist_lock
parport_unregister_device() should never be used when interrupts are
enabled in hardware and irq handler is registered so there is no need to
disable interrupts when using waitlist_lock.  But there is no way to
explain this subtle semantics to lockdep analyzer.

So disable interrupts here too to simplify things.  The price is
negligible.

Dominik Brodowski 2262054e74 pcmcia: remove obsolete and wrong comments
What's worse than no comment? A wrong comment.

Several PCMCIA device drivers contained the same comments, which
were based on how the PCMCIA subsystem worked in the old days of 2.4.,
and which were originally part of a "dummy_cs" driver. These comments
no longer matched at all what is happening now, and therefore should
be removed.

IntType was only set to INT_MEMORY (driver pcmciamtd) or INT_MEMORY_AND_IO
(all other drivers). As this flags seems to relate to ioport access, make
it conditional to the driver having requested IO port access. There are two
drivers which do not request IO ports, but did set INT_MEMORY_AND_IO:
ray_cs and b43. For those, we consistently only set INT_MEMORY in future.

Subsequent patches will convert each user of of_register_platform_driver()

point the of_register_platform_driver()/of_unregister_platform_driver()

Grant Likely 1636f8ac2b sparc/of: Move of_device fields into struct pdev_archdata
This patch moves SPARC architecture specific data members out of
struct of_device and into the pdev_archdata structure.  The reason
for this change is to unify the struct of_device definition amongst
all the architectures.  It also remvoes the .sysdata, .slot, .portid
and .clock_freq properties because they aren't actually used by
anything.

A subsequent patch will replace struct of_device entirely with struct
platform_device and the of_platform support code will share common
routines with the platform bus (but the bus instances themselves can
remain separate).

This patch also adds 'struct resources *resource' and num_resources
to match the fields defined in struct platform_device.  After this
change, 'struct platform_device' can be used as a drop-in replacement
for 'struct of_platform'.

This change is in preparation for merging the of_platform_bus_type
with the platform_bus_type.

However, only a few drivers made use of it, and the userspace

As a first step, remove any usage of dev_node_t from drivers which

Instead of the old pcmcia_request_irq() interface, drivers may now
choose between:

- calling request_irq/free_irq directly. Use the IRQ from *p_dev->irq.

- use pcmcia_request_irq(p_dev, handler_t); the PCMCIA core will
  clean up automatically on calls to pcmcia_disable_device() or
  device ejection.

- drivers still not capable of IRQF_SHARED (or not telling us so) may
  use the deprecated pcmcia_request_exclusive_irq() for the time
  being; they might receive a shared IRQ nonetheless.

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.
