e6d9c80b7c can: peak_pci: add support of some new PEAK-System PCI cards
This patch adds the support of some new PEAK-System PCI cards in the CAN
network sub-system. These are:

PCAN-PCIeC (PCI-ExpressCard)
PCAN-mminiPCI (mini-PCI)
PCAN-PCI (PCI next-gen)

This patch also adds the control of the blinking leds of the PCAN-PCIeC.

a7762b10c1 can: sja1000: fix isr hang when hw is unplugged under load
In the case of hotplug enabled devices (PCMCIA/PCIeC) the removal of the
hardware can cause an infinite loop in the common sja1000 isr.

Use the already retrieved status register to indicate a possible hardware
removal and double check by reading the mode register in sja1000_is_absent.

9a12349663 can: flexcan: Fix CAN_RAW_RECV_OWN_MSGS and CAN_RAW_LOOPBACK
Currently the flexcan driver uses hardware local echo. This blindly
echos all transmitted frames to all receiving sockets, regardless what
CAN_RAW_RECV_OWN_MSGS and CAN_RAW_LOOPBACK are set to.

This patch now submits transmitted frames to be echoed in the transmit
complete interrupt, preserving the reference to the sending
socket. This allows the can protocol to correctly handle the local
echo.

Further this patch moves tx_bytes statistic accounting into the tx_complete
handler.

edd2c26ffb can: cc770: add legacy ISA bus driver for the CC770 and AN82527
This patch adds support for legacy Bosch CC770 and Intel AN82527 CAN
controllers on the ISA or PC-104 bus. The I/O port or memory address
and the IRQ number must be specified via module parameters:

  insmod cc770_isa.ko port=0x310,0x380 irq=7,11

for ISA devices using I/O ports or:

  insmod cc770_isa.ko mem=0xd1000,0xd1000 irq=7,11

for memory mapped ISA devices.

Indirect access via address and data port is supported as well:

  insmod cc770_isa.ko port=0x310,0x380 indirect=1 irq=7,11

Furthermore, the following mode parameter can be defined:

  clk: External oscillator clock frequency (default=16000000 [16 MHz])
  cir: CPU interface register (default=0x40 [DSC])
  bcr: Bus configuration register (default=0x40 [CBY])
  cor: Clockout register (default=0x00)

Note: for clk, cir, bcr and cor, the first argument re-defines the
default for all other devices, e.g.:

  insmod cc770_isa.ko mem=0xd1000,0xd1000 irq=7,11 clk=24000000

is equivalent to

  insmod cc770_isa.ko mem=0xd1000,0xd1000 irq=7,11 clk=24000000,24000000

Only distinct use is checking if NETIF_F_NOCACHE_COPY should be

so it hits other people than before. The default shouldn't be
trusted for performance-critical cases anyway.

For all other uses NETIF_F_NO_CSUM is equivalent to NETIF_F_HW_CSUM.

2e11437427 candev: allow SJW user setting for bittiming calculation
This patch adds support for SJW user settings to not set the synchronization
jump width (SJW) to 1 in any case when using the in-kernel bittiming
calculation.

The ip-tool from iproute2 already supports to pass the user defined SJW
value. The given SJW value is sanitized with the controller specific sjw_max
and the calculated tseg2 value. As the SJW can have values up to 4 providing
this value will lead to the maximum possible SJW automatically. A higher SJW
allows higher controller oscillator tolerances.

951f2f960e drivers/net/can/sja1000/plx_pci.c: eliminate double free
In this code, the failure_cleanup label calls the function
plx_pci_del_card, which frees everything in the card->net_dev array.  dev
is placed in this array immediately after allocation, so the two subsequent
jumps to failure_cleanup should not also call free_sja1000dev, but the
second one does.

If plx_pci_check_sja1000 fails, then free_sja1000dev is also called on
dev.  Because dev is already in the card->net_dev array, this implies that
when plx_pci_del_card is later called, it may get freed again.  So that
entry is reset to NULL after the free.

Finally, if there is a problem with one channel, there will be a hole in the
array.  card->channels counts the number of channels that have succeeded,
and does not keep track of the index of the largest element in the array
that is valid.  So the loop in plx_pci_del_card is changed to go up to
PLX_PCI_MAX_CHAN, which is only 2.

netdevices that are based on serial line disciplines should use netif_rx_ni()

Since we have a struct that defines the sizes of the registers, we don't

b7f080cfe2 net: remove mm.h inclusion from netdevice.h
Remove linux/mm.h inclusion from netdevice.h -- it's unused (I've checked manually).

To prevent mm.h inclusion via other channels also extract "enum dma_data_direction"
definition into separate header. This tiny piece is what gluing netdevice.h with mm.h
via "netdevice.h => dmaengine.h => dma-mapping.h => scatterlist.h => mm.h".
Removal of mm.h from scatterlist.h was tried and was found not feasible
on most archs, so the link was cutoff earlier.

Hope people are OK with tiny include file.

Note, that mm_types.h is still dragged in, but it is a separate story.

The AT91SAM9X5 SOCs have a similar CAN core, but they only have 8 compared
to 16 mailboxes on the AT91SAM9263 SOC. Another difference is that the bits
defining the state of the CAN core are cleared on read, thus the driver
has to derive the state by looking at the error counters.

55db4c64ed Revert "tty: make receive_buf() return the amout of bytes received"
This reverts commit b1c43f82c5.

It was broken in so many ways, and results in random odd pty issues.

It re-introduced the buggy schedule_work() in flush_to_ldisc() that can
cause endless work-loops (see commit a5660b41af: "tty: fix endless
work loop when the buffer fills up").

It also used an "unsigned int" return value fo the ->receive_buf()
function, but then made multiple functions return a negative error code,
and didn't actually check for the error in the caller.

And it didn't actually work at all.  BenH bisected down odd tty behavior
to it:
  "It looks like the patch is causing some major malfunctions of the X
   server for me, possibly related to PTYs.  For example, cat'ing a
   large file in a gnome terminal hangs the kernel for -minutes- in a
   loop of what looks like flush_to_ldisc/workqueue code, (some ftrace
   data in the quoted bits further down).

   ...

   Some more data: It -looks- like what happens is that the
   flush_to_ldisc work queue entry constantly re-queues itself (because
   the PTY is full ?) and the workqueue thread will basically loop
   forver calling it without ever scheduling, thus starving the consumer
   process that could have emptied the PTY."

which is pretty much exactly the problem we fixed in a5660b41af.

Milton Miller pointed out the 'unsigned int' issue.

2e4ceec4ed drivers/net/can/flexcan.c: add missing clk_put
The failed_get label is used after the call to clk_get has succeeded, so it
should be moved up above the call to clk_put.

The failed_req labels doesn't do anything different than failed_get, so
delete it.

A simplified version of the semantic match that finds this problem is as
follows: (http://coccinelle.lip6.fr/)

// <smpl>
@r exists@
expression e1,e2;
statement S;
@@

e1 = clk_get@p1(...);

3d2bdf759f mfd: Use mfd cell platform_data for janz cells platform bits
With the addition of a platform device mfd_cell pointer, MFD drivers
can go back to passing platform data back to their sub drivers.
This allows for an mfd_cell->mfd_data removal and thus keep the
sub drivers MFD agnostic. This is mostly needed for non MFD aware
sub drivers.
