This reverts commit 42c625a486f3 ("net: sched: act_ife: disable bh
when taking ife_mod_lock"), because what ife_mod_lock protects
is absolutely not touched in rate est timer BH context, they have
no race.
A better fix is following up.

After commit 90b73b77d08e, list_head is no longer needed.
Now we just need to convert the list iteration to array
iteration for drivers.

All ops->delete() wants is getting the tn->idrinfo, but we already
have tc_action before calling ops->delete(), and tc_action has
a pointer ->idrinfo.
More importantly, each type of action does the same thing, that is,
just calling tcf_idr_delete_index().
So it can be just removed.

tcf_action_put_many() is mostly called to clean up actions on
failure path, but tcf_action_put_many(&actions[acts_deleted]) is
used in the ugliest way: it passes a slice of the array and
uses an additional NULL at the end to avoid out-of-bound
access.
acts_deleted is completely unnecessary since we can teach
tcf_action_put_many() scan the whole array and checks against
NULL pointer. Which also means tcf_action_delete() should
set deleted action pointers to NULL to avoid double free.

Keep sending mailbox commands to the MFW when it is not responsive ends up
with a redundant amount of timeout expiries.
This patch prints the MCP status on the first command which is not
responded, and blocks the following commands.
Since the (un)load request commands might be not responded due to other
PFs, the patch also adds the option to skip the blocking upon a failure.

The MFW manages an internal lock to prevent concurrent hardware
(de)initialization of different PFs.
This, together with the busy-waiting for the MFW's responses for commands,
might lead to a deadlock during concurrent load or unload of PFs.
This patch adds the option to sleep within the busy-waiting, and uses it
for the (un)load requests (which are not sent from an interrupt context) to
prevent the possible deadlock.

Successive iterations of halting and resuming the management chip (MCP)

The MFW might be reset and re-update its shared memory.
Upon the detection of such a reset the driver rereads this memory, but it
has to wait till the data is valid.

Recently, ops->init() and ops->dump() of all actions were modified to
always obtain tcf_lock when accessing private action state. Actions that
don't depend on tcf_lock for synchronization with their data path use
non-bh locking API. However, tcf_lock is also used to protect rate
estimator stats in softirq context by timer callback.
Change ops->init() and ops->dump() of all actions to disable bh when using
tcf_lock to prevent deadlock reported by following lockdep warning:

Pull RISC-V updates from Palmer Dabbelt:
"This contains some major improvements to the RISC-V port, including
the necessary interrupt controller and timer support to actually make
it to userspace. Support for three devices has been added:
- the ISA-mandated timers on RISC-V systems.
- the ISA-mandated first-level interrupt controller on RISC-V
systems, which is handled as part of our core arch code because
it's very small and tightly tied to the ISA.
- SiFive's platform-level interrupt controller, which talks to the
actual devices.
In addition to these new devices, there are a handful of cleanups all
over the RISC-V tree:
- build fixes for various configurations:
* A fix to the vDSO build's makefile so it respects CFLAGS.
* The addition of __lshrti3, a libgcc derived function necessary
for some 32-bit configurations.
* !SMP && PERF_EVENTS
- Cleanups to the arch code to remove the remnants of old versions of
the drivers that were just properly submitted.
* Some dead code from the timer driver, most of which wasn't ever
even compiled.
* Cleanups of some interrupt #defines, which are now local to the
interrupt handling code.
- Fixes to ptrace(), which while not being sufficient to fully make
GDB work are at least sufficient to get simple GDB tasks to work.
- Early printk support via RISC-V's architecturally mandated SBI
console device.
- A fix to our early debug trap handler to ensure it's always
aligned.
These patches have all been through a fairly extensive review process,
but as this enables a whole pile of functionality (ie, userspace) I'm
confident we'll need to submit a few more patches. The only concrete
issues I know about are the sys_riscv_flush_icache patches, but as I
managed to screw those up on Friday I figured it'd be best to let them
bake another week.
This tag boots a Fedora root filesystem on QEMU's master branch for
me, and before this morning's rebase (from 4.18-rc8 to 4.18) it booted
on the HiFive Unleashed.
Thanks to Christoph Hellwig and the other guys at WD for getting the
new drivers in shape!"

This function was created as a deprecated fallback case back in 2010 by
commit eb14120f743d ("pcmcia: re-work pcmcia_request_irq()") for legacy
cases.
Actual in-kernel users haven't been around for a long while. The last
in-kernel user was apparently removed four years ago by commit
5f5316fcd08e ("am2150: Update nmclan_cs.c to use update PCMCIA API").
Just remove it entirely.

We haven't had lots of deprecation warnings lately, but the rdma use of
it made them flare up again.
They are not useful. They annoy everybody, and nobody ever does
anything about them, because it's always "somebody elses problem". And
when people start thinking that warnings are normal, they stop looking
at them, and the real warnings that mean something go unnoticed.
If you want to get rid of a function, just get rid of it. Convert every
user to the new world order.
And if you can't do that, then don't annoy everybody else with your
marking that says "I couldn't be bothered to fix this, so I'll just spam
everybody elses build logs with warnings about my laziness".
Make a kernelnewbies wiki page about things that could be cleaned up,
write a blog post about it, or talk to people on the mailing lists. But
don't add warnings to the kernel build about cleanup that you think
should happen but you aren't doing yourself.
Don't. Just don't.

"Here is the bit set of char/misc drivers for 4.19-rc1
There is a lot here, much more than normal, seems like everyone is
writing new driver subsystems these days... Anyway, major things here
are:
- new FSI driver subsystem, yet-another-powerpc low-level hardware
bus
- gnss, finally an in-kernel GPS subsystem to try to tame all of the
crazy out-of-tree drivers that have been floating around for years,
combined with some really hacky userspace implementations. This is
only for GNSS receivers, but you have to start somewhere, and this
is great to see.
Other than that, there are new slimbus drivers, new coresight drivers,
new fpga drivers, and loads of DT bindings for all of these and
existing drivers.

Lots of churn here, with tons of cleanups happening in staging

"gasket" driver from Google that needs loads of work and the erofs
filesystem.
Even with adding all of the new drivers and a new filesystem, we are

pull-request: bpf 2018-08-18
The following pull-request contains BPF updates for your *net* tree.
The main changes are:
1) Fix a BPF selftest failure in test_cgroup_storage due to rlimit
restrictions, from Yonghong.
2) Fix a suspicious RCU rcu_dereference_check() warning triggered
from removing a device's XDP memory allocator by using the correct
rhashtable lookup function, from Tariq.
3) A batch of BPF sockmap and ULP fixes mainly fixing leaks and races
as well as enforcing module aliases for ULPs. Another fix for BPF
map redirect to make them work again with tail calls, from Daniel.
4) Fix XDP BPF samples to unload their programs upon SIGTERM, from Jesper.

Netfilter/IPVS fixes for net
The following patchset contains Netfilter/IPVS fixes for your net tree:
1) Infinite loop in IPVS when net namespace is released, from
Tan Hu.
2) Do not show negative timeouts in ip_vs_conn by using the new
jiffies_delta_to_msecs(), patches from Matteo Croce.
3) Set F_IFACE flag for linklocal addresses in ip6t_rpfilter,
from Florian Westphal.
4) Fix overflow in set size allocation, from Taehee Yoo.
5) Use netlink_dump_start() from ctnetlink to fix memleak from
the error path, again from Florian.
6) Register nfnetlink_subsys in last place, otherwise netns
init path may lose race and see net->nft uninitialized data.
This also reverts previous attempt to fix this by increase
netns refcount, patches from Florian.
7) Remove conntrack entries on layer 4 protocol tracker module
removal, from Florian.
8) Use GFP_KERNEL_ACCOUNT for xtables blob allocation, from
Michal Hocko.
9) Get tproxy documentation in sync with existing codebase,
from Mate Eckl.
10) Honor preset layer 3 protocol via ctx->family in the new nft_ct
timeout infrastructure, from Harsha Sharma.
11) Let uapi nfnetlink_osf.h compile standalone with no errors,
from Dmitry V. Levin.
12) Missing braces compilation warning in nft_tproxy, patch from
Mate Eclk.
13) Disregard bogus check to bail out on non-anonymous sets from
the dynamic set update extension.
