staging: xgifb: use arch_phys_wc_add() and ioremap_wc()

The same area used for ioremap() is used for the MTRR area.
Convert the driver from using the x86 specific MTRR code to
the architecture agnostic arch_phys_wc_add(). arch_phys_wc_add()
will avoid MTRR if write-combining is available, in order to
take advantage of that also ensure the ioremap'd area is requested
as write-combining.

There are a few motivations for this:

a) Take advantage of PAT when available

b) Help bury MTRR code away, MTRR is architecture specific and on
   x86 its replaced by PAT

c) Help with the goal of eventually using _PAGE_CACHE_UC over
   _PAGE_CACHE_UC_MINUS on x86 on ioremap_nocache() (see commit
   de33c442e titled "x86 PAT: fix performance drop for glx,
   use UC minus for ioremap(), ioremap_nocache() and
   pci_mmap_page_range()")

The conversion done is expressed by the following Coccinelle
SmPL patch, it additionally required manual intervention to
address all the #ifdery and removal of redundant things which

The Comedi "8255" module is both a standalone Comedi device driver
module for simple devices with one or more 8255 "Programmable Peripheral
Interface" chips at known I/O base addresses (configured at run-time),
and a helper module to configure a 8255-based digital I/O subdevice for
other Comedi drivers.

Split the "8255 subdevice helper" functionality into a new module:
"comedi_8255", leaving the standalone 8255 Comedi driver in the "8255"
module.

The Comedi "detach" routine of the standalone "8255" driver needs to
retrieve the I/O base address passed to the "comedi_8255" module to set
up each subdevice in order to release the I/O port regions it requested
in its "attach" routine.  The "comedi_8255" module stores it in a
"subdevice private" data structure that is no longer known to the "8255"
module, so add a new, exported function `subdev_8255_regbase()` to

The Comedi "8255" driver does not clean up properly on failure.  It can
leave requested I/O port regions unreleased.  Specifically, the Comedi
"attach" handler (`dev_8255_attach()`) requests a specified I/O port
region before calling `subdev_8255_init()` to set up the subdevice.  If
that fails, the "attach" handler returns an error and the Comedi core
will call the "detach" handler (`dev_8255_detach()`) to clean up.  The
"detach" handler is responsible for releasing the I/O port regions
successfully requested by the "attach" handler.  Unfortunately, it is
unable to obtain the base address of the region if the call to
`subdev_8255_init()` failed.

Fix the I/O region leak by releasing the region in the "attach" handler
directly if the call to `subdev_8255_init()` fails.

A recent patch to simplify the lustre large memory allocation
causes new warnings as an unintended side-effect:

lustre/lov/lov_request.c: In function 'lov_finish_set':
lustre/lov/lov_request.c:78:7: warning: unused variable 'len' [-Wunused-variable]
   int len = set->set_oabufs * sizeof(*set->set_pga);
       ^
lustre/obdclass/acl.c: In function 'lustre_ext_acl_xattr_reduce_space':
lustre/obdclass/acl.c:123:6: warning: unused variable 'old_size' [-Wunused-variable]
  int old_size = CFS_ACL_XATTR_SIZE(old_count, ext_acl_xattr);
      ^

The reason is that the 'size' argument to OBD_FREE_LARGE()
is never needed, which was previously hidden by the extra
abstractions.

This avoids the warnings by adding a cast to void, to tell
the compiler that the argument is intentionally unused.
A better fix is probably to remove the entire set of allocation
macros and open-code the normal kernel interface calls.

staging/wilc1000: fix Kconfig dependencies

The newly added wilc1000 driver lacks several Kconfig dependencies,
resulting in a multitude of randconfig build errors, e.g.:

drivers/built-in.o: In function `WILC_WFI_mgmt_tx_cancel_wait':
binder.c:(.text+0x12bd28): undefined reference to `cfg80211_remain_on_channel_expired'
drivers/built-in.o: In function `WILC_WFI_CfgSetChannel':
binder.c:(.text+0x12c9d8): undefined reference to `ieee80211_frequency_to_channel'
drivers/built-in.o: In function `WILC_WFI_CfgAlloc':

drivers/built-in.o: In function `wilc_netdev_init':

drivers/built-in.o: In function `linux_spi_init':
binder.c:(.text+0x210a68): undefined reference to `spi_register_driver'

This change ensures that we always have at least one of SPI or MMC
enabled, and are only able to pick an interface that works. It also
adds all the missing dependencies for networking infrastructure

In order to make it readable, I also took the liberty of re-indenting

staging: sm750fb: use arch_phys_wc_add() and ioremap_wc()

The same area used for ioremap() is used for the MTRR area.
Convert the driver from using the x86 specific MTRR code to
the architecture agnostic arch_phys_wc_add(). arch_phys_wc_add()
will avoid MTRR if write-combining is available, in order to
take advantage of that also ensure the ioremap'd area is requested
as write-combining.

There are a few motivations for this:

a) Take advantage of PAT when available

b) Help bury MTRR code away, MTRR is architecture specific and on
   x86 its replaced by PAT

c) Help with the goal of eventually using _PAGE_CACHE_UC over
   _PAGE_CACHE_UC_MINUS on x86 on ioremap_nocache() (see commit

staging: unisys: Remove unused intr

The conversion to visor_device caused some compile issues.The main
problem was the new fields in 'struct visor_device' were not public.
Remove one that wasn't being used for now.

staging: unisys: Add checks for creation

There was a bunch of channel creation checks before the
visorchannel_create function was called, moving some of those
checks inside.  This keeps the outside code cleaner and handles
the situation where a caller forgets to make these checks.

staging: unisys: Add a function to set the clientpartition

This patch is an attempt to help hide the channel info behind
accessory functions.  I was trying to keep visorchannel as private
as possible.

The only function missing that seemed to be needed for now was
the ability to set the clientpartition.  So I expose that here.

staging: unisys: Add visor device find routine

If we are going to remove the bus_info structs than we need a way
to find the devices when the *_create/destroy cmds are sent over
the vmchannel.

This function crudely impements what pci has.  It takes a bus_no
and dev_no and finds the matching 'struct visor_device'.

This function can/should be optimzed later once we get our heads
wrapped around its needs.  For now, I am using dev_no=0 to mean
the visorbus itself.

The function is limited to chipset.c only because it is only needed
to do the lookups upon receiving a vmchannel command.  Future patches
will make sure the resulting 'struct visor_device' is used every
where else.

Also allow visorbus_type to be more visible for use.

staging: unisys: Prep for removing 'info' structs

The visorbus driver has three _info structs lying around
(device, bus, channel) that store subsets of info from the
bigger structs.

Having these structs around make resource handling very difficult
and more complicated than it needs to be.  Use the device
infrastructure and instead pass 'struct visor_device' all
over the place.

In order to do that 'struct visor_device' needs to get smarter.
This patch adds the pieces to prep for it.  The new elements
will be used in later patches.

staging: unisys: Clean up device sysfs attributes

Properly hook into the struct device groups element.  This allows the
core infrastructure to manage the files instead of the bus layer.  And
makes the code easier to read.

I didn't clean up the _show functions just modified them a bit to handle
the different args for now and to prevent a build warning.

staging: unisys: Move the visorbus device underneath devices

Mimicing what other drivers do, this seems appropriate.  Yeah, it
is a bus, but it is a bus _device_.  This makes things work better
and smoother.  Now the sysfs looks like

[root@dhcp-17-174 visorbus]# ls -l /sys/bus/visorbus/devices/
total 0
lrwxrwxrwx. 1 root root 0 Apr 17 16:09 vbus1:dev2 ->
../../../devices/visorbus1/vbus1:dev2
lrwxrwxrwx. 1 root root 0 Apr 17 16:09 visorbus1 ->
../../../devices/visorbus1

Which looks correct.  All the attributes are still correct too, based on my
very minimal testing of 'ls -lR'. :-)

This will help remove a bunch of cruft from the code and let the kernel
