====================
Intel Wired LAN Driver Fixes 2018-10-24
This series contains fixes for the ice driver.
Anirudh fixes a namespace issue which was introduced with a previous
patch to remove ice_netpoll. Fixed up the device ID define names to
align with the branding string names. Use the capability count returned
by the firmware, instead of calculating the count. Introduced driver
workarounds due to current firmware limitations. Fixed the queue
mapping for a VF, which needs to be set in the config and scatter queue
modes. Fixed the driver which is setup to handle link status events
(LSE), even though the firmware does not have this feature yet, so add
the ability to poll for link status changes while we wait for updated
firmware.

When the physical link goes up or down, the driver is supposed to
receive a link status event (LSE). The driver currently has the code
to handle LSEs but there is no firmware support for this feature yet.
So this patch adds the ability for the driver to poll for link status
changes. The polling itself is done in ice_watchdog_subtask.
For namespace cleanliness, this patch also removes code that handles
LSE. This code will be reintroduced once the feature is officially
supported.

Allocate VF interrupts using VPINT_ALLOC_PCI. Multiple interrupts are
specified as a range from "first" to "last".
Also, according to the spec, the queue mapping for a VF needs to be set
in both contig and scatter queue modes. So make this change as well.

ice_dev_onetime_setup contains a couple of driver workarounds for current
firmware limitations. These workarounds are expected to go away once
these limitations are fixed in the firmware.
On a firmware release that has these issues addressed, these workarounds
(while unnecessary) will not break anything.

Commit '3cf71bc9904d ("drm/i915: Re-apply "Perform link quality check,
unconditionally during long pulse"")' applies a work around for sinks
that don't signal link loss. The work around does not need to have to be
that broad as the issue was seen with only one particular monitor; limit
this only for external displays as eDP features like PSR turn off the link
and the driver ends up retraining the link seeeing that link is not
synchronized.

Comment claims link needs to be retrained because the connected sink raised
a long pulse to indicate link loss. If the sink did so,
intel_dp_hotplug() would have handled link retraining. Looking at the
logs in Bugzilla referenced in commit '3cf71bc9904d ("drm/i915: Re-apply
Perform link quality check, unconditionally during long pulse"")', the
issue is that the sink does not trigger an interrupt. What we want is
->detect() from user space to check link status and retrain. Ville's
review for the original patch also indicates the same root cause. So,
rewrite the comment.
v2: Patch split and rewrote comment.

Pull siginfo updates from Eric Biederman:
"I have been slowly sorting out siginfo and this is the culmination of
that work.
The primary result is in several ways the signal infrastructure has
been made less error prone. The code has been updated so that manually
specifying SEND_SIG_FORCED is never necessary. The conversion to the
new siginfo sending functions is now complete, which makes it
difficult to send a signal without filling in the proper siginfo
fields.
At the tail end of the patchset comes the optimization of decreasing
the size of struct siginfo in the kernel from 128 bytes to about 48
bytes on 64bit. The fundamental observation that enables this is by
definition none of the known ways to use struct siginfo uses the extra
bytes.
This comes at the cost of a small user space observable difference.
For the rare case of siginfo being injected into the kernel only what
can be copied into kernel_siginfo is delivered to the destination, the
rest of the bytes are set to 0. For cases where the signal and the
si_code are known this is safe, because we know those bytes are not
used. For cases where the signal and si_code combination is unknown
the bits that won't fit into struct kernel_siginfo are tested to
verify they are zero, and the send fails if they are not.
I made an extensive search through userspace code and I could not find
anything that would break because of the above change. If it turns out
I did break something it will take just the revert of a single change
to restore kernel_siginfo to the same size as userspace siginfo.
Testing did reveal dependencies on preferring the signo passed to
sigqueueinfo over si->signo, so bit the bullet and added the
complexity necessary to handle that case.
Testing also revealed bad things can happen if a negative signal
number is passed into the system calls. Something no sane application
will do but something a malicious program or a fuzzer might do. So I
have fixed the code that performs the bounds checks to ensure negative
signal numbers are handled"

'default n' is the default value for any bool or tristate Kconfig
setting so there is no need to write it explicitly.
Also since commit f467c5640c29 ("kconfig: only write '# CONFIG_FOO
is not set' for visible symbols") the Kconfig behavior is the same
regardless of 'default n' being present or not:
...
One side effect of (and the main motivation for) this change is making
the following two definitions behave exactly the same:
config FOO
bool
config FOO
bool
default n
With this change, neither of these will generate a
'# CONFIG_FOO is not set' line (assuming FOO isn't selected/implied).
That might make it clearer to people that a bare 'default n' is
redundant.

XEN_BACKEND doesn't actually depend on XEN_DOM0. DomUs can serve
backends to other DomUs. One example is a service VM providing network
backends.
The original Kconfig defaulted Dom0 to y and it could be disabled. DomU
could not select the option. With the new Kconfig, we default y for
Dom0 and n for DomU. Either can then toggle the selection.

The networking merge brought in the experimental support for the
Qualcomm ath10k system NOC, which selects QCOM_QMI_HELPERS as a
dependency.
But the ATH10K_SNOC option (which selects QCOM_QMI_HELPERS) depends on
ARCH_QCOM || COMPILE_TEST in order to get wider build testing than just
the unusual QCOM architecture build, while the QCOM_QMI_HELPERS option
doesn't have that COMPILE_TEST option and is limited to only ARCH_QCOM.
As a result, a "make allmodconfig" complains
WARNING: unmet direct dependencies detected for QCOM_QMI_HELPERS

Clang warns a few times:
drivers/scsi/3w-sas.c:386:11: warning: implicit conversion from 'int' to
'char' changes value from 128 to -128 [-Wconstant-conversion]
cdb[4] = TW_ALLOCATION_LENGTH; /* allocation length */
~ ^~~~~~~~~~~~~~~~~~~~
Update cdb's type to unsigned char, which matches the type of the cdb
member in struct TW_Command_Apache.

If, for example, I don't enable CONFIG_TCM_PSCSI, then every time I load
the target subsystem, I get an annoying
Unable to load target_core_pscsi
kernel log message. Instead let's only request_module() on things if
that code is enabled.

In the iov_iter struct, separate the iterator type from the iterator
direction and use accessor functions to access them in most places.
Convert a bunch of places to use switch-statements to access them rather
then chains of bitwise-AND statements. This makes it easier to add further
iterator types. Also, this can be more efficient as to implement a switch
of small contiguous integers, the compiler can use ~50% fewer compare
instructions than it has to use bitwise-and instructions.
Further, cease passing the iterator type into the iterator setup function.
The iterator function can set that itself. Only the direction is required.
