spi: Fixes for v4.10
The usual small smattering of driver specific fixes. A few bits that
stand out here:
- The R-Car patches adding fallbacks are just adding new compatible
strings to the driver so that device trees are written in a more
robustly future proof fashion, this isn't strictly a fix but it's
just new IDs and it's better to get it into mainline sooner to
improve the ABI.
- The DesignWare "switch to new API part 2" patch is actually a
misleadingly titled fix for a bit that got missed in the original
conversion.

This patch replaced "n" by "len" bytes of data in qspi_transfer_in() and

In qspi_transfer_in(), when receiving the last n (or len) bytes of data,
one bogus byte was written in the receive buffer.
This code leads to a buffer overflow.
"jffs2: jffs2_scan_eraseblock(): Magic bitmask 0x1985 not found
at 0x03b40000: 0x1900 instead
jffs2: jffs2_scan_eraseblock(): Magic bitmask 0x1985 not found
at 0x03b40004: 0x000c instead"
The error message above happens when trying to mount, unmount,
and remount a jffs2-formatted device.
This patch removed the bogus write to fixes: 3be09bec42a800d4
"spi: rspi: supports 32bytes buffer for DUAL and QUAD"
And here is Geert's comment:
"spi: rspi: Fix bogus received byte in qspi_transfer_in()
When there are less than QSPI_BUFFER_SIZE remaining bytes to be received,
qspi_transfer_in() writes one bogus byte in the receive buffer, possibly
leading to a buffer overflow.
This can be reproduced by mounting, unmounting, and remounting a
jffs2-formatted device, causing lots of warnings like:
"jffs2: jffs2_scan_eraseblock(): Magic bitmask 0x1985 not found
at 0x03b40000: 0x1900 instead"
Remove the bogus write to fix this. "

Commit a92e7c3d82a1 ("spi: s3c64xx: consider the case when the CS
line is not connected") introduced an inconsistency between the
binding, where the disconnected CS line was marked as
'no-cs-readback', and the driver.
The driver is erroneously checking for that attribute with
property name of 'broken-cs'.
Check for 'no-cs-readback' in the driver as well.

In the case of Renesas R-Car hardware we know that there are generations of
SoCs, e.g. Gen 2 and Gen 3. But beyond that it's not clear what the
relationship between IP blocks might be. For example, I believe that
r8a7790 is older than r8a7791 but that doesn't imply that the latter is a
descendant of the former or vice versa.
We can, however, by examining the documentation and behaviour of the
hardware at run-time observe that the current driver implementation appears
to be compatible with the IP blocks on SoCs within a given generation.
For the above reasons and convenience when enabling new SoCs a
per-generation fallback compatibility string scheme is being adopted for
drivers for Renesas SoCs.
Also:
* Deprecate renesas,sh-msiof. It seems poorly named as it is only
compatible with SH-Mobile. It also appears unused in mainline.

The sync_cmos_clock function in kernel/time/ntp.c first tries to update
the internal clock of the cpu by calling the "update_persistent_clock64"
architecture specific function. If this returns -ENODEV, it then tries
to update an external RTC using "rtc_set_ntp_time".
On the mips architecture, the weak implementation of the underlying
function would return 0 if it wasn't overridden. This meant that the
sync_cmos_clock function would never try to update an external RTC
(if both CONFIG_GENERIC_CMOS_UPDATE and CONFIG_RTC_SYSTOHC are
configured)
Returning -ENODEV instead, means that an external RTC will be tried.

When trying to get a regulator we may get deferred and we see
this noise:
smsc911x 1b800000.ethernet-ebi2 (unnamed net_device) (uninitialized):
couldn't get regulators -517
Then the driver continues anyway. Which means that the regulator
may not be properly retrieved and reference counted, and may be
switched off in case noone else is using it.
Fix this by returning silently on deferred probe and let the
system work it out.

This patch is based on an earlier one submitted
by Jon Maxwell with the following commit message:
"We recently encountered a bug where a few customers using ibmveth on the
same LPAR hit an issue where a TCP session hung when large receive was
enabled. Closer analysis revealed that the session was stuck because the
one side was advertising a zero window repeatedly.
We narrowed this down to the fact the ibmveth driver did not set gso_size
which is translated by TCP into the MSS later up the stack. The MSS is
used to calculate the TCP window size and as that was abnormally large,
it was calculating a zero window, even although the sockets receive buffer
was completely empty."
We rely on the Virtual I/O Server partition in a pseries
environment to provide the MSS through the TCP header checksum
field. The stipulation is that users should not disable checksum
offloading if rx packet aggregation is enabled through VIOS.
Some firmware offerings provide the MSS in the RX buffer.
This is signalled by a bit in the RX queue descriptor.

"Several fixes to the DSM (ACPI device specific method) marshaling
implementation.
I consider these urgent enough to send for 4.9 consideration since
they fix the kernel's handling of ARS (Address Range Scrub) commands.
Especially for platforms without machine-check-recovery capabilities,
successful execution of ARS commands enables the platform to
potentially break out of an infinite reboot problem if a media error
is present in the boot path. There is also a one line fix for a
device-dax read-only mapping regression.
Commits 9a901f5495e2 ("acpi, nfit: fix extended status translations

output length handling") fixes the kernel's handling of zero-length
results, this never would have worked in the past, but we only just
recently discovered a BIOS implementation that emits this arguably
spec non-compliant result.
The remaining two commits are additional fall out from thinking
through the implications of a zero / truncated length result of the
ARS Status command.
In order to mitigate the risk that these changes introduce yet more
regressions they are backstopped by a new unit test in commit
