net: Fix percpu counters deadlock
When we converted the protocol atomic counters such as the orphan
count and the total socket count deadlocks were introduced due to
the mismatch in BH status of the spots that used the percpu counter

Based on the diagnosis and patch by Peter Zijlstra, this patch
fixes these issues by disabling BH where we may be in process

drivers/net/usb: use USB API functions rather than constants
This set of patches introduces calls to the following set of functions:
usb_endpoint_dir_in(epd)
usb_endpoint_dir_out(epd)
usb_endpoint_is_bulk_in(epd)
usb_endpoint_is_bulk_out(epd)
usb_endpoint_is_int_in(epd)

usb_endpoint_type(epd)
usb_endpoint_xfer_bulk(epd)
usb_endpoint_xfer_control(epd)
usb_endpoint_xfer_int(epd)
usb_endpoint_xfer_isoc(epd)
In some cases, introducing one of these functions is not possible, and it
just replaces an explicit integer value by one of the following constants:
USB_ENDPOINT_XFER_BULK
USB_ENDPOINT_XFER_CONTROL
USB_ENDPOINT_XFER_INT
USB_ENDPOINT_XFER_ISOC
In drivers/net/wireless/zd1211rw/zd_usb.c the code:
(endpoint->bEndpointAddress & USB_TYPE_MASK) == USB_DIR_OUT
is suspicious. If it is intended to use USB_ENDPOINT_DIR_MASK rather than
USB_TYPE_MASK, then the whole conditional test could be converted to a call
to usb_endpoint_is_bulk_in.
An extract of the semantic patch that makes these changes is as follows:

netns: foreach_netdev_safe is insufficient in default_device_exit
During network namespace teardown we either move or delete
all of the network devices associated with a network namespace.
In the case of veth devices deleting one will also delete it's
pair device. If both devices are in the same network namespace
then for_each_netdev_safe is insufficient as next may point
to the second veth device we have deleted.
To avoid problems I do what we do in __rtnl_kill_links and
restart the scan of the device list, after we have deleted
a device.
Currently dev_change_netnamespace does not appear to suffer from
this problem, but wireless devices are also paired and likely
should be moved between network namespaces together. So I have
errored on the side of caution and restart the scan of the network
devices in that case as well.

kvm-s390: implement config_changed for virtio on s390
This patch implements config_changed for the s390 virtio transport.
We use the least significant bit of the interrupt parameter field

or the config_changed callback.
This method is compatible with old host and guest code. Old 64 bit guests
will not check the bit and trigger a harmless additional vring_interrupt
call. Old host code will never set this bit, this is also safe.
This patch also takes care of a potential future 31 bit virtio transport

virtio: struct device - replace bus_id with dev_name(), dev_set_name()
This patch is part of a larger patch series which will remove
the "char bus_id[20]" name string from struct device. The device
name is managed in the kobject anyway, and without any size
limitation, and just needlessly copied into "struct device".
To set and read the device name dev_name(dev) and dev_set_name(dev)
must be used. If your code uses static kobjects, which it shouldn't
do, "const char *init_name" can be used to statically provide the
name the registered device should have. At registration time, the
init_name field is cleared, to enforce the use of dev_name(dev) to
access the device name at a later time.
We need to get rid of all occurrences of bus_id in the entire tree
to be able to enable the new interface. Please apply this patch,
and possibly convert any remaining remaining occurrences of bus_id.
We want to submit a patch to -next, which will remove bus_id from
"struct device", to find the remaining pieces to convert, and finally
switch over to the new api, which will remove the 20 bytes array
and does no longer have a size limitation.

ide: fix IDE ACPI regression breaking suspend
Commit
4dde4492d850a4c9bcaa92e5bd7f4eebe3e2f5ab ("ide: make drive->id
an union (take 2)") accidentally introduced an IDE ACPI regression which
at least on some machines confuses ACPI and breaks suspend. Fix it.
Fixes kernel.org bug #12279:
http://bugzilla.kernel.org/show_bug.cgi?id=12279
[ Sorry about the bug (IDE ACPI is not used by default so it managed
to slip in). Still it is kind of surprising that the bug breaks
suspend as it shouldn't impact anything except IDE ACPI (it seems
that it uncovered either some ACPI/PM deficiency or a BIOS bug). ]

sata_sil: add Large Block Transfer support
This implements support for the Large Block Transfer feature found in Silicon
Image 311x controllers. This allows transferring bigger contiguous chunks of
data from system memory and avoids the 64KB boundary restriction of standard
SFF controllers.
This is based on a patch from Jeff Garzik (from the sii-lbt branch of
libata-dev) but includes a few bug fixes: Since the bmdma2 register does not
implement the status bits, the original bmdma register must be used except
where the bmdma2 register is required. As well the DMA boundary should be
31-bit instead of 32-bit since the top bit of the length field is still
required for the PRD end-of-table flag.

[ARM] pxafb: add support for overlay1 and overlay2 as framebuffer devices
PXA27x and later processors support overlay1 and overlay2 on-top of the
base framebuffer (although under-neath the base is also possible). They
support palette and no-palette RGB formats, as well as YUV formats (only
available on overlay2). These overlays have dedicated DMA channels and
behave in a similar way as a framebuffer.
This heavily simplified and re-structured work is based on the original
pxafb_overlay.c (which is pending for mainline merge for a long time).
The major problems with this pxafb_overlay.c are (if you are interested
in the history):
1. heavily redundant (the control logics for overlay1 and overlay2 are
actually identical except for some small operations, which are now
abstracted into a 'pxafb_layer_ops' structure)
2. a lot of useless and un-tested code (two workarounds which are now
fixed on mature silicons)
3. cursorfb is actually useless, hardware cursor should not be used
this way, and the code was actually un-tested for a long time.
The code in this patch should be self-explanatory, I tried to add minimum
comments. As said, this is basically simplified, there are several things
still on the pending list:
1. palette mode is un-supported and un-tested (although re-using the
palette code of the base framebuffer is actually very easy now with
previous clean-up patches)
2. fb_pan_display for overlay(s) is un-supported
3. the base framebuffer can actually be abstracted by 'pxafb_layer' as
well, which will help further re-use of the code and keep a better
and consistent structure. (This is the reason I named it 'pxafb_layer'
instead of 'pxafb_overlay' or something alike)
See Documentation/fb/pxafb.txt for additional usage information.

[ARM] pxafb: cleanup of the color format manipulation code
1. introduce var_to_depth() to calculate the color depth including the
transparency bit
2. the conversion from 'fb_var_screeninfo' to LCCR3 BPP bits can be re-
used by overlays (in OVLxC1), thus an individual pxafb_var_to_bpp()
has been separated out.
3. pxafb_setmode() should really set the color bitfields correctly at
begining, introduce a pxafb_set_pixfmt() for this
4. allow user apps to specify color formats within fb_var_screeninfo,
and checking of this in pxafb_check_var() has been simplified as
below:
a) pxafb_var_to_bpp() should pass - which means a basically correct
bits_per_pixel and color depth setting
b) the RGBT bitfields are then forced into supported values by
pxafb_set_pixfmt()

[ARM] pxafb: allow pxafb_set_par() to start from arbitrary yoffset
Note the var->yres_virtual is only re-calculated from the fix.smem_len
when text mode acceleration is enabled (which is default), this is due
to the issue as Russell suggested below:
Previous experience of doing this with the X server and acornfb is that
it causes all sorts of problems - it seems to force the X server into
assuming that the framebuffer should be panned no matter what settings
you ask it for.
The recommended workaround (implemented in acornfb) is to only do these
kinds of adjustments if text mode acceleration is enabled. IIRC, the X
server should be disabling text mode acceleration when it maps the
framebuffer. I seem to remember that there are X servers which forget
to do that though.

[ARM] pxafb: allow video memory size to be configurable
The amount of video memory size is decided according to the following
order:
1. <xres> x <yres> x <bits_per_pixel> by default, which is the backward
compatible way
2. size specified in platform data
3. size specified in module parameter 'options' string or specified in
kernel boot command line (see updated Documentation/fb/pxafb.txt)
And now since the memory is allocated from system memory, the pxafb_mmap
can be removed and the default fb_mmap() should be working all right.
Also, since we now have introduced the 'struct pxafb_dma_buff' for DMA
descriptors and palettes, the allocation can be separated cleanly.
NOTE: the LCD DMA actually supports chained transfer (i.e. page-based
transfers), to simplify the logic and keep the performance (with less
TLB misses when accessing from memory mapped user space), the memory
is allocated by alloc_pages_*() to ensures it's physical contiguous.
