Commit 592282cf2eaa33409c6511ddd3f3ecaa57daeaaa fixed some missing directory
c/mtime updates in part by introducing a dinode update in ocfs2_add_entry().
Unfortunately, ocfs2_link() (which didn't update the directory inode before)
is now missing a single journal credit. Fix this by doubling the number of
inode updates expected during hard link creation.

Some HID devices by Apple have both keyboard and mouse interfaces; the
keyboard interface is handled by usbhid, but the mouse (really
touchpad) interface must be handled by the separate 'appletouch'
driver. Using HID_QUIRK_IGNORE will make hiddev ignore both
interfaces, therefore a new quirk flag to ignore only the mouse
interface is required.

hidinput_{open,close}() functions do not belong to usbhid, but
to the generic HID layer. Move them, and fix hooks in struct
hid_device, so that now the callbacks are done to transport-specific
_open() functions, but not input_open() functions.

hid-debug.h contains a lot of code, and should not therefore
be a header.
This patch moves the code to generic hid layer as .c source, and
introduces CONFIG_HID_DEBUG to conditionally compile it, instead
of playing with #define DEBUG and including hid-debug.h.

Add new quirk HID_QUIRK_SKIP_OUTPUT_REPORTS to skip output reports
when enumerating reports on a hid-input device. Add this quirk and
HID_QUIRK_MULTI_INPUT to 0810:0001.
PantherLord Twin USB Joystick, 0810:0001 has separate input reports
for 2 distinct game controllers in the same interface, so it needs
HID_QUIRK_MULTI_INPUT. However, the device also contains one output
report per controller which is used to control the force feedback
function, and we do not want those to appear as separate input
devices as well. The simplest approach seems to be to add a quirk to
skip output reports on 0810:0001, and allow the force feedback
driver to handle those.

The iWARP connection manager uses the ib_addr services to do route
resolution (neighbour discovery in the IP world). The ib_addr
netevent callback routine, however, currently only acts on InfiniBand
neighbour updates. It needs to act on ethernet neighbour updates as
well.
This patch just removes filtering on device type altogether and will
trigger on any neighour updates where the nud_type is valid. This
simplifies the code some.

When there is a call to send_tsk_mgmt SRP posts a send and waits for 5
seconds to get a response.
When the QP is in the error state it is obvious that there will be no
response so it is quite useless to wait. In fact, the timeout causes
SRP to wait a long time to reconnect when a QP error occurs. (Each
abort and each reset_device calls send_tsk_mgmt, which waits for the
timeout). The following patch solves this problem by identifying the
failure and returning an immediate error code.

struct ib_wc currently only includes the local QP number: this matches
the IB spec, but seems mostly useless. The following patch replaces
this with the pointer to qp itself, and updates all low level drivers
and all users.
This has the following advantages:
- Ability to get a per-qp context through wc->qp->qp_context
- Existing drivers already have the qp pointer ready in poll cq, so
this change actually saves a tiny bit (extra memory read) on data path
(for ehca it would actually be expensive to find the QP pointer when
polling a CQ, but ehca does not support SRQ so we can leave wc->qp as
NULL for ehca)
- Users that need the QP number can still get it through wc->qp->qp_num
Use case:
In IPoIB connected mode code, I have a common CQ shared by multiple
QPs. To track connection usage, I need a way to get at some per-QP
context upon the completion, and I would like to avoid allocating
context object per work request just to stick a QP pointer into it.
With this code, I can just use wc->qp->qp_context.

MMC high-speed, wide bus support and SD high-speed
are functions that aren't critical for correct
operation of the card. As such, they shouldn't mark
the card as bad or dead when there is a failure
activating these features.
This is needed in particular on some really stupid
hardware (e.g. Winbond's) where not all data transfer
commands are supported.

The wbsd hardware is so incredibly brain damaged that it has an internal
list of commands that result in data transfers. The result being that
commands that aren't on this list aren't supported.
Instead of locking up, waiting for a data interrupt that will never come,
we try to fail a bit more gracefully.

Many controllers have an upper limit on the number of blocks that can be
transferred in one request. Allow the host drivers to specify this and make
sure we avoid hitting this limit.
Also change the max_sectors field to avoid confusion. This makes it map
less directly to the block layer limits, but as they didn't apply directly
on MMC cards anyway, this isn't a great loss.

Hardware does not say whether card was inserted or removed when reporting
socket events. Moreover, during suspend, media can be removed or switched
to some other card type without notification. Therefore, for each socket
in the change set the following is performed:
1. If there's active device in the socket it's unregistered
2. Media detection is performed
3. If detection recognizes supportable media, new device is registered

In order to support correct suspend and resume several changes were needed:
1. Switch from work_struct to tasklet for command handling. When device
suspend is called workqueues are already frozen and can not be used.
2. Separate host initialization code from driver's probe and don't rely
on interrupts for host initialization. This, in turn, addresses two
problems:
a) Resume needs to re-initialize the host, but can not assume that
device interrupts were already re-armed.
b) Previously, probe will return successfully before really knowing
the state of the host, as host interrupts were not armed in time.
Now it uses polling to determine the real host state before returning.
3. Separate termination code from driver's remove. Termination may be caused
by resume, if media changed type or became unavailable during suspend.

Previously, stop command was issued right after BRS (block received/sent)
event. Stop command completion event could interfere with the card busy
event, causing miscount of the written blocks.
This patch ensures that stop command issued as last action for a
particular command, after DMA sompletion event and written block
count verification.
