Handle VERSION Rx protocol packets. We should respond to a VERSION packet
with a string indicating the Rx version. This is a maximum of 64 characters
and is padded out to 65 chars with NUL bytes.Note that other AFS clients use the version request as a NAT keepalive so we
need to handle it rather than returning an abort.The standard formulation seems to be:
built --
for example:
" OpenAFS 1.6.2 built 2013-05-07 "
(note the three extra spaces) as obtained with:
rxdebug grand.mit.edu -version
from the openafs package.

Subject: rxrpc: switch rxrpc_send_data() to iov_iter primitivesincorrectly changes a do-while loop into a while loop in rxrpc_send_data().
Unfortunately, at least one pass through the loop is required - even if
there is no data - so that the packet the closes the send phase can be
sent if MSG_MORE is not set.Signed-off-by: David Howells

Pull ARM SoC fixes from Olof Johansson:
"The latest and greatest fixes for ARM platform code. Worth pointing
out are:- Lines-wise, largest is a PXA fix for dealing with interrupts on DT
that was quite broken. It's still newish code so while we could
have held this off, it seemed appropriate to include now- Some GPIO fixes for OMAP platforms added a few lines. This was
also fixes for code recently added (this release).- Small OMAP timer fix to behave better with partially upstreamed
platforms, which is quite welcome.- Allwinner fixes about operating point control, reducing
overclocking in some cases for better stability.plus a handful of other smaller fixes across the map"

The UART reference clock speed is 7273.8 kHz, not 72738 kHz.
Dots aren't usually used in node names even though ePAPR permits
them. However, this can easily be avoided by expressing the

Now GPIO syscon driver produces bunch of warnings during the
boot of Kesytone 2 SoCs:
gpio-syscon soc:keystone_dsp_gpio@02620240: can't read the dir register offset!
gpio-syscon soc:keystone_dsp_gpio@2620244: can't read the dir register offset!This message unintentionally was added using dev_err(), but its
actual log level is debug, because third cell of "ti,syscon-dev" is
optional.Hence change it to dev_dbg() as it should be.

The IMG PDC watchdog driver heartbeat module parameter has no default so
it is initialised to zero. This results in the following warning during
probe:imgpdc-wdt 2006000.wdt: Initial timeout out of range! setting max timeout
The module parameter description implies that the default value should
be PDC_WDT_DEF_TIMEOUT, which isn't yet used, so initialise it to that.Also tweak the heartbeat module parameter description for consistency.

The IMG PDC watchdog probe function calls pdc_wdt_stop() prior to
watchdog_set_drvdata(), causing a NULL pointer dereference when
pdc_wdt_stop() retrieves the struct pdc_wdt_dev pointer using
watchdog_get_drvdata() and reads the register base address through it.Fix by moving the watchdog_set_drvdata() call earlier, to where various
other pdc_wdt->wdt_dev fields are initialised.Fixes: 93937669e9b5 ("watchdog: ImgTec PDC Watchdog Timer Driver")

This is a very similar bug in the load detect code fixed in

Author: Daniel Vetter

But this time around it was the initial fb code that forgot to update
the plane->crtc pointer. Otherwise it's the exact same bug, with the
exact same restrains (any set_config call/ioctl that doesn't disable
the pipe papers over the bug for free, so fairly hard to hit in normal
testing). So if you want the full explanation just go read that one
over there - it's rather long ...Cc: Matt Roper
