cbbc00be2c iommu/amd: Prevent binding other PCI drivers to IOMMU PCI devices
AMD IOMMU driver makes use of IOMMU PCI devices, so prevent binding other
PCI drivers to IOMMU PCI devices.

This fixes a bug reported by Boris that system suspend/resume gets broken
on AMD platforms. For more information, please refer to:

e3096c9c7c genirq: Fix handle_bad_irq kerneldoc comment
A recent cleanup removed the 'irq' parameter from many functions, but
left the documentation for this in place for at least one function.

This removes it.

9d67dc5da5 genirq: Export handle_bad_irq
A cleanup of the omap gpio driver introduced a use of the
handle_bad_irq() function in a device driver that can be
a loadable module.

This broke the ARM allmodconfig build:

ERROR: "handle_bad_irq" [drivers/gpio/gpio-omap.ko] undefined!

This patch exports the handle_bad_irq symbol in order to
allow the use in modules.

d49ae37c61 Merge branch 'net-non-modular'
Paul Gortmaker says:

====================
make non-modular code explicitly non-modular

[v2: drop m68k patches that Geert converted to modules; add one ARM
 driver patch ; update net-next baseline to today; switch to ARM
 for build testing.]

In a previous merge window, we made changes to allow better
delineation between modular and non-modular code in commit
0fd972a7d9 ("module: relocate module_init
from init.h to module.h").  This allows us to now ensure module code
looks modular and non-modular code does not accidentally look modular
just to avoid suffering build breakage.

Here we target code that is, by nature of their Makefile and/or
Kconfig settings, only available to be built-in, but implicitly
presenting itself as being possibly modular by way of using modular
headers, macros, and functions.

The goal here is to remove that illusion of modularity from these
files, but in a way that leaves the actual runtime unchanged.
In doing so, we remove code that has never been tested and adds
no value to the tree.  And we continue the process of expecting a
level of consistency between the Kconfig/Makefile of code and the
code in use itself.

Fortuntately the net subsystem has relatively few instances, given
the overall amount of code and drivers it contains.  For comparison
there are over 300 instances tree wide, resulting in a possible net
removal of on the order of 5000 lines of unused code.

Build tested on net-next from today, on ARM, since that is the arch
where the one ethernet driver changed here is available.

b3c8ec35a9 drivers/net/ethernet: make ti/cpsw-phy-sel.c explicitly non-modular
The Kconfig currently controlling compilation of this code is:

drivers/net/ethernet/ti/Kconfig:config TI_CPSW_PHY_SEL
drivers/net/ethernet/ti/Kconfig:        bool "TI CPSW Switch Phy sel Support"

...meaning that it currently is not being built as a module by anyone.

Lets remove the couple traces of modularity so that when reading the
driver there is no doubt it is builtin-only.

Since module_platform_driver() uses the same init level priority as
builtin_platform_driver() the init ordering remains unchanged with
this commit.

Also note that MODULE_DEVICE_TABLE is a no-op for non-modular code.

We also delete the MODULE_LICENSE tag etc. since all that information
was (or is now) contained at the top of the file in the comments.

change to one of the other priority initcalls (subsys?) at any later
date, if desired.

stuff even though it is not modular itself.

We move the information from the MODULE_LICENSE tag to the top of the
file, since that information is not captured anywhere else.  The
MODULE_ALIAS_NET_PF_PROTO becomes a no-op in the non modular case, so
it is removed.

====================
Intel Wired LAN Driver Updates 2015-10-08

This series contains updates to i40e and i40evf only (again).

Jesse fixes an issue where the driver was issuing a WARN_ON during ring
size changes because the code was cloning the rx_ring struct but not
zeroing out the pointers before allocating new memory, so simply zero
out the pointers.  Also reduced the function call overhead by moving
the interrupt enable function by moving it to the header file, which it
in turn allows us to inline it.  Also does a thorough job of code
cleanup to fix spaces after declarations, remove unnecessary braces
and breaks, remove another __func__ use and general code tidiness.

Mitch adds mover verbose error messages when the number of supported VFs
is reported in driver init and it different from the number reported in
config space.  Updated the VF driver to now detect a reset with the
VF_ARQLEN register since the enable bit is cleared when the VF is reset
and it stays cleared until the VF driver processes the reset and
re-enables the admin queue which is more reliable than using the
VFGEN_RSTAT as previously.

Neerav adds parsing for CEE DCBx TLVs from the LLDP MIB since there is
a need to get the CEE DesiredCfg Tx by firmware and DCB configuration
Rx from peer for debug and other application purposes.

Carolyn fixes a problem where the PF's Flow Director filter table would
have an entry that the hardware was unable to add, when this occurs an
invalid entry gets replayed and a valid one is lost.

Matt fixes an issue where multiple link up messages can be logged
resulting from admin queue link status timing when link properties are
changed.

Shannon adds the ability to control the period link polling through
ethtool to be able to switch it off and on for debugging link issues.

Serey explicitly assigns the enum index for each VSI type so that the PF
and VF always reference to the same VSI type event if the enum lists
are different.

2bffa1503c dm cache: fix NULL pointer when switching from cleaner policy
The cleaner policy doesn't make use of the per cache block hint space in
the metadata (unlike the other policies).  When switching from the
cleaner policy to mq or smq a NULL pointer crash (in dm_tm_new_block)
was observed.  The crash was caused by bugs in dm-cache-metadata.c
when trying to skip creation of the hint btree.

The minimal fix is to change hint size for the cleaner policy to 4 bytes
(only hint size supported).

621bd0f698 drm: Fix locking for sysfs dpms file
With atomic drivers we need to make sure that (at least in general)
property reads hold the right locks. But the legacy dpms property is
special and can be read locklessly. Since userspace loves to just
randomly look at that all the time (like with "status") do that.

To make it clear that we play tricks use the READ_ONCE compiler
barrier (and also for paranoia).

Note that there's not really anything bad going on since even with the
new atomic paths we eventually end up not chasing any pointers (and
hence possibly freed memory and other fun stuff). The locking WARNING
has been added in

f578f5f453 i40e/i40evf: pass QOS handle to VF
The VF really doesn't care about the QOS handle but it will in the
future. Since the VF only uses TC0, send it that handle. On the VF
side, save the handle and use it to populate the QOS params when we call
into the client interface.

ee5c1e92dd i40evf: detect reset more reliably
Using VFGEN_RSTAT to detect a VF reset is an endeavor that is fraught
with peril. It's entirely too easy to miss a reset because none of the
bits are sticky. By the time the VF driver reads the register, the reset
may have been processed and cleaned up by the PF driver, leaving the
register in the same state that it was before the reset.

Instead, detect a reset with the VF_ARQLEN register. When the VF is
reset, the enable bit in this register is cleared, and it stays cleared
until the VF driver processes the reset and re-enables the admin queue.

Because we now deal with multiple registers in the reset and watchdog
tasks, rename the rstat_val variable to reg_val.

66486cd717 i40e/i40evf: Explicitly assign enum index for VSI type
Ran into an issue where PF's VSI type list was different from VF's,
which was resulted in different enum index. The VSI type list can
be different depending on what build flag is used for PF and VF.

The change is to explicitly assign enum index for each VSI type
so that PF and VF always reference to the same VSI type event if the
enum lists are different.

9ac7726637 i40e: add switch for link polling
There's been some need for controlling the periodic link polling for
debugging link issues.  This patch enables switching it off and on
through an ethtool private flag.  The link poll remains on by default,
but can be turned off with
	ethtool --set-priv-flags p261p1 LinkPolling off
and later turned back on with
	ethtool --set-priv-flags p261p1 LinkPolling on

To check the current status, use
	ethtool --show-priv-flags p261p1

c156f856ad i40e: Fix multiple link up messages
This patch addresses an issue where multiple link up messages can be logged
resulting from aq link status timing when link properties are changed (fc,
speed, etc.); solved by using a single function to handle status printing
and adding a mechanism to track whether link state (up or down) has
actually changed.

3487b6c30c i40e: Fix for extra Flow Director filter in table after error
This patch fixes a problem where the PF's fdir filter table would have an
entry that the hw was unable to add. This notification happens in the hot
path, so instead of trying to fix it then, we note the location in the
failure case and delete it during regular fdir subtask callback. Without
this patch, a case can occur where an invalid entry gets replayed and a
valid one is not.

96c8d0738a i40e: add more verbose error messages
Under certain circumstances, the device may not have enough resources to
enable all of the VFs that it advertises in config space. Although the
number of supported VFs is reported upon driver init, it is not obvious
when this is different from the number reported in config space. To
eliminate this confusion, add an error message explaining the problem.
Additionally, move the 'Allocating VFs' message down below the error
checks so as to prevent further confusion.
