Marvell pxa controllers have private registers that may need to be
modified before and after a reset is done.
For example, the SD reset operation, RESET_ALL, will reset the private
registers to their default state. This will cause the clock adjustment
registers that may have been programmed to have incorrect values.
RESET_DATA sometimes needs to be delayed before the reset is done
(depending on SoC) to enable any transactions being handled by the
SDIO card to be completed. Needed in pre SD 3.0 silicon to handle
clock gating.
Implement hooks to allow this to happen.

Commit 373e6a (mmc: sdhci: R1B command handling + MMC_CAP_ERASE) moved the
handling of SDHCI_QUIRK_TIMEOUT_USES_SDCLK from sdhci_calc_timeout() to
sdhci_add_host(). This causes division by zero errors on at least the S3C
SDHCI controller as the quirk implementation needs host->clock set to work
but host->clock has not been set when sdhci_add_host() is called.
Fix this by backing out that portion of the change, the clock may vary at
runtime anyway. It does occur to me that we may want to move the quirk to
where we set the clock but this seems more invasive and I'm concerned
about undesirable side effects.

Some SD host controllers (noticed on an integrated JMicron SD reader on an
HP Pavilion dv5-1250eo laptop) don't update the dma address register before
signaling a dma interrupt due to a dma boundary. Update the register
manually to the next boundary (by default 512KiB), at which the transfer
stopped.
As long as each transfer is at most 512KiB in size (guaranteed by a BUG_ON
in sdhci_prepare_data()) and the boundary is kept at the default value,
this fix is needed at most once per transfer. Smaller boundaries are taken
care of by counting the transferred bytes.

The wl12xx device supports disconnecting the pull-up resistor on
CD/DAT[3] (pin 1) of the card.
Tell SDIO core to disconnect that resistor during card init,
since we don't need it at that point (and anyway all
hosts shall provide pull-up resistors on all data lines DAT[3:0]
as described in section 6 of the SD physical specification).
As a result, this may save some power, but it's also generally healthy
since it prevents both ends from pulling up that pin, which
results in undesirable asymmetric physical bus.

6b5eda36 followed SDIO spec part E1 section 8, which states that
in case SDIO interrupts are being used to wake up a suspended host,
then it is required to switch to 1-bit mode before stopping the clock.
Before switching to 1-bit mode (or back to 4-bit mode on resume),
make sure that SDIO interrupts are really being used to wake the host.
This is helpful for devices which have an external irq line (e.g.
wl1271), and do not use SDIO interrupts to wake up the host.
In this case, switching to 1-bit mode (and back to 4-bit mode on resume)
is not necessary.

A non-zero, non-descript value is needed as the hash key. The hash variable was left un-initialized; but sometimes it gets a zero value
and hashing is not effective. The constant value used now (not of any significance) seems to work fine.

32bpp means ARGB 8888 in the driver, therfore the transparency length
and offset should be 8 and 24 respectively. However, the transparency
length and offset were previously 0, which means that the driver supports
RGB 888 without alpha blending when 32bpp is used.
So, the transparency checking in 32bpp is corrected so that the
transparency length and offset are 8 and 24 respectively.

An administrative detach used to request a state change directly to D_DISKLESS,
first suspending IO to avoid the last put_ldev() occuring from an endio handler,
potentially in irq context.
This is not enough on the receiving side (typically secondary), we may miss
some peer_req on the way to local disk, which then may do the last put_ldev()
from their drbd_peer_request_endio().
This patch makes the detach always go through the intermediate D_FAILED state.
We may consider to rename it D_DETACHING.
Alternative approach would be to create yet an other work item to be scheduled
on the worker, do the destructor work from there, and get the timing right.

The old (optimistic) implementation could shrink the bio size
on an primary device.
Shrinking the bio size on a primary device is bad. Since there
we might get BIOs with the old (bigger) size shortly after
we published the new size.
The new implementation is more conservative, and eventually
increases the max_bio_size on a primary device (which is valid).
It does so, when it knows the local limit AND the remote limit.
We cache the last seen max_bio_size of the peer in the meta
data, and rely on that, to make the operation of single
nodes more efficient.

If there is no replication traffic within the idle timeout
(ping-int seconds), DRBD will send a P_PING,
and adjust the timeout to ping-timeout.
If there is no P_PING_ACK received within this ping-timeout,
DRBD finally drops the connection, and tries to re-establish it.
To decide which timeout was active, we compared the current timeout
with the ping-timeout, and dropped the connection, if that was the case.
By default, ping-int is 10 seconds, ping-timeout is 500 ms.
Unfortunately, if you configure ping-timeout to be the same as ping-int,
expiry of the idle-timeout had been mistaken for a missing ping ack,
and caused an immediate reconnection attempt.
Fix:
Allow both timeouts to be equal, use a local variable
to store which timeout is active.

We limit ourselves to a configurable maximum number of pages used as
temporary bio pages.
If the configured "max_buffers" is not big enough to match the bandwidth
of the respective deployment, a distributed deadlock could be triggered
by e.g. fast online verify and heavy application IO.
TCP connections would block on congestion, because both receivers
would wait on pages to become available.
Fortunately the respective senders in this case would be able to give
back some pages already. So do that.

In case a write failes on the local disk, go into D_INCONSISTENT

Read retry remote was already in place.
Actually the documentation needs to get fixed now. Since the
application is still shielded from the error. (as long as we have
only a single disk failing) The difference to detach is that
we keep the disk. And therefore might keep all the other, still
working sectors up to date.

Commit e40cc4bdfd ("x86/hwmon: register alternate sibling upon CPU
removal") extends this functionality to register the HT sibling of a CPU
which is taken offline, to ensure that sensor attributes are provided if
at least one HT sibling of a core is online.

Ehea will not register multicast groups in phyp if the physical
interface is in promiscuous mode. But it should register if the
logical port is in promiscuous mode, but the physical port is not.
Ehea physical promiscuous mode is defined by ehea_port->promisc,
while logical port is defined by IFF_PROMISC.
So currently, if the user set the interface in promiscuous mode,
IGMP will not be registred in PHYP, and PHYP will never pass
the multicast packet to the logical port, which is bad
So, this patch just fixes it, assuring that we register in phyp
if the physical port is not on promiscuous mode.

The eTSEC includes a PTP clock with quite a few features. This patch adds
support for the basic clock adjustment functions, plus two external time
stamps, one alarm, and the PPS callback.

This patch adds an infrastructure for hardware clocks that implement
IEEE 1588, the Precision Time Protocol (PTP). A class driver offers a
registration method to particular hardware clock drivers. Each clock is
presented as a standard POSIX clock.
The ancillary clock features are exposed in two different ways, via
the sysfs and by a character device.

I did the hci_ldisc thing as an evil merge, cleaning things up.
cpu_sibling_mask() is not defined unless CONFIG_SMP is defined, so it
must not be used directly in the code without ifdef protection.
To solve the problem and avoid ifdefs in the code, define
for_each_sibling() and use it instead.
