92f842eac7 [S390] store indication fault optimization

page faults to avoid the protection faults that immediatly follow
the page fault if the access has been a write.

6931be0803 [S390] cpu hotplug/idle: move cpu_die call to enabled context
There is no difference if cpu_die is called from enabled or disabled
context. Except that the fast_gup code might be called via
cpu_die -> idle_task_exit -> __mm_drop -> crst_table_free. Which in
turn grabs and releases a spinlock using the _bh ops, which is not
allowed in irq disabled context, since spin_unlock_bh will
unconditionally enable interrupts again.
To get rid of the warning emitted by the softirq code just move the
code to enabled context.

In this case this doesn't fix a bug, we just get rid of a warning.

7ea8d32199 [S390] dasd: let recovery cqr inherit flags from failed cqr
The usual way to recover a failed DASD ECKD request (cqr) is to create
a new request with an appropriate recovery CCW program.  Certain
features, e.g. failfast, can be enabled per request and are stored in
the requests flags. These flags have to be copied from the failed to
the recovery request, to let the recovery request use the same
features as the original one.

238ec4efee [S390] zero page cache synonyms
If the zero page is mapped to virtual user space addresses that differ
only in bit 2^12 or 2^13 we get L1 cache synonyms which can affect
performance. Follow the mips model and use multiple zero pages to avoid
the synonyms.

The only Wimedia LLC Protocol (WLP) hardware was an Intel i1480 chip
with a beta release of firmware that was never commercially available as
a product.  This hardware and firmware is no longer available as Intel
sold their UWB/WLP IP.  I also see little prospect of other WLP

0e7adbe263 ALSA: hda - Disable sticky PCM stream assignment for AD codecs
The sticky PCM stream assignment introduced in 2.6.36 kernel seems
causing problems on AD codecs.  At some time later, the streaming no
longer works by unknown reason.  A simple workaround is to disable
sticky-assignment for these codecs.

6b96724e50 Revalidate caches on lock
Instead of blindly zapping the caches, attempt to revalidate them if
the server has indicated that it uses high resolution timestamps.

NFSv4 should be able to always revalidate the cache since the
protocol requires the update of the change attribute on modification of
the data.  In reality, there are servers (the Linux NFS server
for example) that do not obey this requirement and use ctime as the
basis for change attribute.  Long term, the server needs to be fixed.
At this time, and to be on the safe side, continue zapping caches if
the server indicates that it does not have a high resolution timestamp.

This appears to be caused by the function rpc_verify_header() first
calling xprt_release(), then doing a call_refresh. If we release the

calling anything else.

bf5d95c826 i2c-viapro: Don't log nacks
Transactions not acked can happen every now and then, in particular
during device detection, and various transaction types can be used for
this purpose. So stop logging this event, except when debugging is
enabled. This is what other similar drivers (e.g. i2c-i801 or
i2c-piix4) do.

db79f2a1d2 i2c/pca954x: Remove __devinit and __devexit from probe and remove functions
The underlying I2C adapter may or may not be present when this driver
gets initialized, and may disappear later, so there is no safe time at
which the probe and remove functions can be discarded.

ae63b13bbe i2c/mux: Driver for PCA9541 I2C Master Selector
This patch adds support for PCA9541, an I2C Bus Master Selector.
The driver is modeled as single channel I2C Multiplexer to be able to utilize
the I2C multiplexer framework.

51b54ba9bb i2c: Optimize function i2c_detect()
Check the class flags before allocating the temporary i2c_client
structure, to avoid allocating it when we don't need it.

Also optimize the inner loop a bit.

9cb2c2726e i2c-amd8111: Add proper error handling
The functions the functions amd_ec_wait_write and amd_ec_wait_read have an
unsigned return type, but return a negative constant to indicate an error
condition.

A sematic match that finds this problem is as follows:
(http://coccinelle.lip6.fr/)

// <smpl>
@exists@
identifier f;
constant C;
@@

 unsigned f(...)
 { <+...
*  return -C;
 ...+> }
// </smpl>

Fixing amd_ec_wait_write and amd_ec_wait_read leads to the need to adjust
the return type of the functions amd_ec_write and amd_ec_read, which are
the only functions that call amd_ec_wait_write and amd_ec_wait_read.
amd_ec_write and amd_ec_read, in turn, are only called from within the
function amd8111_access, which already returns a signed typed value.  Each
of the calls to amd_ec_write and amd_ec_read are updated using the
following semantic patch:

// <smpl>
@@
@@

+ status = amd_ec_write
- amd_ec_write
  (...);
+ if (status) return status;

@@
@@

+ status = amd_ec_read
- amd_ec_read
  (...);
+ if (status) return status;
// </smpl>

The patch also adds the declaration of the status variable.
