The inline isa_register_driver stub simply allows compilation on systems
with CONFIG_ISA disabled; the dummy isa_register_driver does not
register an isa_driver at all. The inline isa_register_driver should
return -ENODEV to indicate lack of support when attempting to register
an isa_driver on such a system with CONFIG_ISA disabled.

Several modern devices, such as PC/104 cards, are expected to run on
modern systems via an ISA bus interface. Since ISA is a legacy interface
for most modern architectures, ISA support should remain disabled in
general. Support for ISA-style drivers should be enabled on a per driver
basis.
To allow ISA-style drivers on modern systems, this patch introduces the
ISA_BUS_API and ISA_BUS Kconfig options. The ISA bus driver will now
build conditionally on the ISA_BUS_API Kconfig option, which defaults to
the legacy ISA Kconfig option. The ISA_BUS Kconfig option allows the
ISA_BUS_API Kconfig option to be selected on architectures which do not
enable ISA (e.g. X86_64).
The ISA_BUS Kconfig option is currently only implemented for X86
architectures. Other architectures may have their own ISA_BUS Kconfig
options added as required.

====================
Netfilter fixes for net
The following patchset contains Netfilter fixes for your net tree,
they are rather small patches but fixing several outstanding bugs in
nf_conntrack and nf_tables, as well as minor problems with missing
SYNPROXY header uapi installation:
1) Oneliner not to leak conntrack kmemcache on module removal, this
problem was introduced in the previous merge window, patch from
Florian Westphal.
2) Two fixes for insufficient ruleset loop validation, one due to
incorrect flag check in nf_tables_bind_set() and another related to
silly wrong generation mask logic from the walk path, from Liping
Zhang.
3) Fix double-free of anonymous sets on error, this fix simplifies the
code to let the abort path take care of releasing the set object,
also from Liping Zhang.
4) The introduction of helper function for transactions broke the skip
inactive rules logic from the nft_do_chain(), again from Liping
Zhang.
5) Two patches to install uapi xt_SYNPROXY.h header and calm down
kbuild robot due to missing #include <linux/types.h>.

The ctx structure passed into bpf programs is different depending on bpf
program type. The verifier incorrectly marked ctx->data and ctx->data_end
access based on ctx offset only. That caused loads in tracing programs
int bpf_prog(struct pt_regs *ctx) { .. ctx->ax .. }
to be incorrectly marked as PTR_TO_PACKET which later caused verifier
to reject the program that was actually valid in tracing context.
Fix this by doing program type specific matching of ctx offsets.

1) gre_parse_header() can be called from gre_err()
At this point transport header points to ICMP header, not the inner
header.
2) We can not really change transport header as ipgre_err() will later
assume transport header still points to ICMP header (using icmp_hdr())
3) pskb_may_pull() logic in gre_parse_header() really works
if we are interested at zone pointed by skb->data
4) As Jiri explained in commit b7f8fe251e46 ("gre: do not pull header in
ICMP error processing") we should not pull headers in error handler.
So this fix :
A) changes gre_parse_header() to use skb->data instead of
skb_transport_header()
B) Adds a nhs parameter to gre_parse_header() so that we can skip the
not pulled IP header from error path.
This offset is 0 for normal receive path.
C) remove obsolete IPV6 includes

The implementation of net_dbg_ratelimited in the CONFIG_DYNAMIC_DEBUG
case was added with 2c94b5373 ("net: Implement net_dbg_ratelimited() for
CONFIG_DYNAMIC_DEBUG case"). The implementation strategy was to take the
usual definition of the dynamic_pr_debug macro, but alter it by adding a
call to "net_ratelimit()" in the if statement. This is, in fact, the
correct approach.
However, while doing this, the author of the commit forgot to surround
fmt by pr_fmt, resulting in unprefixed log messages appearing in the
console. So, this commit adds back the pr_fmt(fmt) invocation, making
net_dbg_ratelimited properly consistent across DEBUG, no DEBUG, and
DYNAMIC_DEBUG cases, and bringing parity with the behavior of
dynamic_pr_debug as well.

Liping Zhang says:
"Users may add such a wrong nft rules successfully, which will cause an
endless jump loop:
# nft add rule filter test tcp dport vmap {1: jump test}
This is because before we commit, the element in the current anonymous
set is inactive, so osp->walk will skip this element and miss the
validate check."
To resolve this problem, this patch passes the generation mask to the
walk function through the iter container structure depending on the code
path:
1) If we're dumping the elements, then we have to check if the element
is active in the current generation. Thus, we check for the current
bit in the genmask.
2) If we're checking for loops, then we have to check if the element is
active in the next generation, as we're in the middle of a
transaction. Thus, we check for the next bit in the genmask.
Based on original patch from Liping Zhang.

d_walk() relies upon the tree not getting rearranged under it without
rename_lock being touched. And we do grab rename_lock around the
places that change the tree topology. Unfortunately, branch reordering
is just as bad from d_walk() POV and we have two places that do it
without touching rename_lock - one in handling of cursors (for ramfs-style
directories) and another in autofs. autofs one is a separate story; this
commit deals with the cursors.
* mark cursor dentries explicitly at allocation time
* make __dentry_kill() leave ->d_child.next pointing to the next
non-cursor sibling, making sure that it won't be moved around unnoticed
before the parent is relocked on ascend-to-parent path in d_walk().
* make d_walk() skip cursors explicitly; strictly speaking it's
not necessary (all callbacks we pass to d_walk() are no-ops on cursors),
but it makes analysis easier.

It seems like in the process of refactoring pwm_config() to utilize the
newly-introduced pwm_apply_state() API, some args/bounds checking was
dropped.
In particular, I noted that we are now allowing invalid period
selections, e.g.:
# echo 1 > /sys/class/pwm/pwmchip0/export
# cat /sys/class/pwm/pwmchip0/pwm1/period
100
# echo 101 > /sys/class/pwm/pwmchip0/pwm1/duty_cycle
[... driver may or may not reject the value, or trigger some logic bug ...]
It's better to see:
# echo 1 > /sys/class/pwm/pwmchip0/export
# cat /sys/class/pwm/pwmchip0/pwm1/period
100
# echo 101 > /sys/class/pwm/pwmchip0/pwm1/duty_cycle
-bash: echo: write error: Invalid argument
This patch reintroduces some bounds checks in both pwm_config() (for its
signed parameters; we don't want to convert negative values into large
unsigned values) and in pwm_apply_state() (which fix the above described
behavior, as well as other potential API misuses).

Socket option PACKET_FANOUT_DATA takes a struct sock_fprog as argument
if PACKET_FANOUT has mode PACKET_FANOUT_CBPF. This structure contains
a pointer into user memory. If userland is 32-bit and kernel is 64-bit
the two disagree about the layout of struct sock_fprog.
Add compat setsockopt support to convert a 32-bit compat_sock_fprog to
a 64-bit sock_fprog. This is analogous to compat_sock_fprog support for

Today, the node guid exposed to mlx5 Ethernet VFs is zero, therefore

Whenever the administrator sets a MAC for a VF, derive the node guid
from it and set it as well in the following way:

in drivers/of/of_reserved_mem.c but is not declared in any of the
header files. Add the declaration of this to avoid the warning:

The compilation of of_pci.c is governed by CONFIG_OF_PCI, but the
corresponding declarations in of_pci.h are inconsistently guarded by
CONFIG_OF, with the result that if CONFIG_PCI is disabled for an OF
platform, the dangling external declarations are still active and the
inline stub definitions not. So far this has managed to go unnoticed
since it happens that the only references to these functions are from
code which itself depends on CONFIG_PCI or CONFIG_OF_PCI.
Fix this with the appropriate config guard so that any new callers
outside PCI-specific code don't start unexpectedly breaking under
certain configs.

While this prior commit:
54cf809b9512 ("locking,qspinlock: Fix spin_is_locked() and spin_unlock_wait()")
... fixes spin_is_locked() and spin_unlock_wait() for the usage
in ipc/sem and netfilter, it does not in fact work right for the
usage in task_work and futex.
So while the 2 locks crossed problem:
spin_lock(A) spin_lock(B)
if (!spin_is_locked(B)) spin_unlock_wait(A)
foo() foo();
... works with the smp_mb() injected by both spin_is_locked() and
spin_unlock_wait(), this is not sufficient for:
flag = 1;
smp_mb(); spin_lock()
spin_unlock_wait() if (!flag)
// add to lockless list
// iterate lockless list
... because in this scenario, the store from spin_lock() can be delayed
past the load of flag, uncrossing the variables and loosing the
guarantee.
This patch reworks spin_is_locked() and spin_unlock_wait() to work in
both cases by exploiting the observation that while the lock byte
store can be delayed, the contender must have registered itself
visibly in other state contained in the word.
It also allows for architectures to override both functions, as PPC
and ARM64 have an additional issue for which we currently have no
generic solution.

Commit 76931edd54f8 ("leds: fix brightness changing when software blinking
is active") changed the semantics of led_set_brightness() which according
to the documentation should disable blinking upon any brightness setting.
Moreover it made it different for soft blink case, where it was possible
to change blink brightness, and for hardware blink case, where setting
any brightness greater than 0 was ignored.
While the change itself is against the documentation claims, it was driven
also by the fact that timer trigger remained active after turning blinking
off. Fixing that would have required major refactoring in the led-core,
led-class, and led-triggers because of cyclic dependencies.
Finally, it has been decided that allowing for brightness change during
blinking is beneficial as it can be accomplished without disturbing
blink rhythm.
The change in brightness setting semantics will not affect existing
LED class drivers that implement blink_set op thanks to the LED_BLINK_SW
flag introduced by this patch. The flag state will be from now on checked
in led_set_brightness() which will allow to distinguish between software
and hardware blink mode. In the latter case the control will be passed
directly to the drivers which apply their semantics on brightness set,
which is disable the blinking in case of most such drivers. New drivers
will apply new semantics and just change the brightness while hardware
blinking is on, if possible.
The issue was smuggled by subsequent LED core improvements, which modified
the code that originally introduced the problem.

Jonathan writes:
First round of iio fixes for the 4.7 cycle.
A slightly bumper set due to travel delaying the pull request and a fair few
issues with the recent merge window patches. Patches all over the place.
The st-sensors one is probably the most involved, but definitly solves the
issues seen. Note there are some other issues around that handler
(and the fact that a lot of boards tie a level interrupt chip to an
edge interrupt only irq chip). These are not regressions however, so
will turn up the slow route.
* core
- iio_trigger_attach_pollfunc had some really badly wrong error handling.
Another nasty triggered whilst chasing down issues with the st sensors
rework below.
* ad5592r
- fix an off by one error when allocating channels.
* am2315
- a stray mutex unlock before we ever take the lock.
* apds9960
- missing a parent in the driver model (which should be the i2c device).
Result is it doesn't turn up under /sys/bus/i2c/devices which some
userspace code uses for repeatable device identification.
* as3935
- ABI usage bug which meant a processed value was reported as raw. Now
reporting scale as well to ensure userspace has the info it needs.
- Don't return processed value via the buffer - it doesn't conform to
the ABI and will overflow in some cases.
- Fix a wrongly sized buffer which would overflow trashing part of the
stack. Also move it onto the heap as part of the fix.
* bh1780
- a missing return after write in debugfs lead to an incorrect read and
a null pointer dereference.
- dereferencing the wrong pointer in suspend and resume leading to
unpredictable results.
- assign a static name to avoid accidentally ending up with no name if
loaded via device tree.
* bmi160
- output data rate for the accelerometer was incorrectly reported. Fix it.
- writing the output data rate was also wrong due to reverse parameters.
* bmp280
- error message for wrong chip ID gave the wrong expected value.
* hdc100x
- mask for writing the integration time was wrong allowin g us to get
'stuck' in a particular value with no way back.
- temperature reported in celsius rather than millicelsius as per the
ABI.
- Get rid of some incorrect data shifting which lead to readings being
rather incorrect.
* max44000
- drop scale attribute for proximity as it is an unscaled value (depends
on what is in range rather than anything knowable at the detector).
* st-pressure
- ABI compliance fixes - units were wrong.
* st-sensors
- We introduced some nasty issues with the recent switch over to a
a somewhat threaded handler in that we broke using a software trigger
with these devices. Now do it properly. It's a larger patch than ideal
for a fix, but the logic is straight forward.
- Make sure the trigger is initialized before requesting the interrupt.
This matters now the interrupt can be shared. Before it was ugly and wrong
but short of flakey hardware could not be triggered.
- Hammer down the dataready pin at boot - otherwise with really
unlucky timing things could get interestingly wedged requiring a hard power
down of the chip.

The offset in the core file used to be tracked with ->written field of
the coredump_params structure. The field was retired in favour of
file->f_pos.
However, ->f_pos is not maintained for pipes which leads to breakage.
Restore explicit tracking of the offset in coredump_params. Introduce
->pos field for this purpose since ->written was already reused.

====================
Netfilter/IPVS fixes for net
The following patchset contains two Netfilter/IPVS fixes for your net
tree, they are:
1) Fix missing alignment in next offset calculation for standard
targets, introduced in the previous merge window, patch from
Florian Westphal.
2) Fix to correct the handling of outgoing connections which use the
SIP-pe such that the binding of a real-server is updated when needed.
This was an omission from changes introduced by Marco Angaroni in
the previous merge window too, to allow handling of outgoing
connections by the SIP-pe. Patch and report came via Simon Horman.

When offloading classifiers such as u32 or flower to hardware, and the
qdisc is clsact (TC_H_CLSACT), then we need to differentiate its classes,
since not all of them handle ingress, therefore we must leave those in
software path. Add a .tcf_cl_offload() callback, so we can generically
handle them, tested on ixgbe.

ib_device_cap_flags 64-bit expansion caused caps overlapping
and made consumers read wrong device capabilities. For example
IB_DEVICE_SG_GAPS_REG was falsely read by the iser driver causing
it to use a non-existing capability. This happened because signed
int becomes sign extended when converted it to u64. Fix this by
casting IB_DEVICE_ON_DEMAND_PAGING enumeration to ULL.
