SUNRPC: Allow cache lookups to use RCU protection rather than the r/w spinlock
Instead of the reader/writer spinlock, allow cache lookups to use RCU for looking up entries. This is more efficient since modifications can occur while other entries are being looked up. Note that for now, we keep the reader/writer spinlock until all users have been converted to use RCU-safe freeing of their cache entries.

i2c: sh_mobile: Remove dummy runtime PM callbacks
Platform drivers don't need dummy runtime PM callbacks that just return success and non-NULL pm pointer in their struct device_driver in order to have runtime PM happening. This has changed since following commits: |

i2c: uniphier-f: fix race condition when IRQ is cleared
The current IRQ handler clears all the IRQ status bits when it bails
out. This is dangerous because it might clear away the status bits
that have just been set while processing the current handler. If this
happens, the IRQ event for the latest transfer is lost forever.
The IRQ status bits must be cleared *before* the next transfer is
kicked.

i2c: uniphier-f: fix occasional timeout error
Currently, a timeout error could happen at a repeated START condition.
For a (non-repeated) START condition, the controller starts sending
data when the UNIPHIER_FI2C_CR_STA bit is set. However, for a repeated
START condition, the hardware starts running when the slave address is
written to the TX FIFO - the write to the UNIPHIER_FI2C_CR register is
actually unneeded.
Because the hardware is already running before the IRQ is enabled for
a repeated START, the driver may miss the IRQ event. In most cases,
this problem does not show up since modern CPUs are much faster than
the I2C transfer. However, it is still possible that a context switch
happens after the controller starts, but before the IRQ register is
set up.
To fix this,
- Do not write UNIPHIER_FI2C_CR for repeated START conditions.
- Enable IRQ *before* writing the slave address to the TX FIFO.
- Disable IRQ for the current CPU while queuing up the TX FIFO;
If the CPU is interrupted by some task, the interrupt handler
might be invoked due to the empty TX FIFO before completing the
setup.

i2c: uniphier-f: make driver robust against concurrency
This is unlikely to happen, but it is possible for a CPU to enter
the interrupt handler just after wait_for_completion_timeout() has
expired. If this happens, the hardware is accessed from multiple
contexts concurrently.
Disable the IRQ after wait_for_completion_timeout(), and do nothing
from the handler when the IRQ is disabled.

TTY/Serial patches for 4.20-rc1
Here is the big tty and serial pull request for 4.20-rc1 Lots of little things here, including a merge from the SPI tree in order to keep things simpler for everyone to sync around for one platform.

Staging/IIO patches for 4.20-rc1
Here is the big staging and IIO driver pull request for 4.20-rc1.
There are lots of things here, we ended up adding more lines than
removing, thanks to a large influx of Comedi National Instrument device
support. Someday soon we need to get comedi out of staging...
Other than the comedi drivers, the "big" things here are:
- new iio drivers
- delete dgnc driver (no one used it and no one had the hardware
anymore)
- vbox driver updates and fixes
- erofs fixes
- tons and tons of tiny checkpatch fixes for almost all staging
drivers
All of these have been in linux-next, with the last few happening a bit
"late" due to them getting stuck on my laptop during travel to the
Mantainers summit.
When merging with your tree, there will be 2 merge conflicts, both files
will be simple to resolve, just delete them :)

"Highlights this time around are the end of Matthew's work to remove
the custom 9p request cache and use a slab directly for requests, with
some extra patches on my end to not degrade performance, but it's a
very good cleanup.
Tomas and I fixed a few more syzkaller bugs (refcount is the big one),
and I had a go at the coverity bugs and at some of the bugzilla
reports we had open for a while.
I'm a bit disappointed that I couldn't get much reviews for a few of
my own patches, but the big ones got some and it's all been soaking in
linux-next for quite a while so I think it should be OK.

platform/x86: Add Intel AtomISP2 dummy / power-management driver
The Image Signal Processor found on Cherry Trail devices is brought up in D0 state on devices which have camera sensors attached to it. The ISP will not enter D3 state again without some massaging of its registers beforehand and the ISP not being in D3 state blocks the SoC from entering S0ix modes. There was a driver for the ISP in drivers/staging but that got removed again because it never worked. It does not seem likely that a real driver for the ISP will be added to the mainline kernel anytime soon. This commit adds a dummy driver which contains the necessary magic from the staging driver to powerdown the ISP, so that Cherry Trail devices where the ISP is used will properly use S0ix modes when suspended. Together with other recent S0ix related fixes this allows S0ix modes to be entered on e.g. a Chuwi Hi8 Pro and a HP x2 210.

net: diag: document swapped src/dst in udp_dump_one.
Since its inception, udp_dump_one has had a bug where userspace
needs to swap src and dst addresses and ports in order to find
the socket it wants. This is because it passes the socket source
address to __udp[46]_lib_lookup's saddr argument, but those
functions are intended to find local sockets matching received
packets, so saddr is the remote address, not the local address.
This can no longer be fixed for backwards compatibility reasons,
so add a brief comment explaining that this is the case. This
will avoid confusion and help ensure SOCK_DIAG implementations
of new protocols don't have the same problem.

Merge branch 'macsec-fixes'
Sabrina Dubroca says: ==================== macsec: linkstate fixes This series fixes issues with handling administrative and operstate of macsec devices. Radu Rendec proposed another version of the first patch [0] but I'd rather not follow the behavior of vlan devices, going with macvlan does instead. Patrick Talbert also reported the same issue to me. The second patch is a follow-up. The restriction on setting the device up is a bit unreasonable, and operstate provides the information we need in this case.

macsec: let the administrator set UP state even if lowerdev is down
Currently, the kernel doesn't let the administrator set a macsec device
up unless its lower device is currently up. This is inconsistent, as a
macsec device that is up won't automatically go down when its lower
device goes down.
Now that linkstate propagation works, there's really no reason for this
limitation, so let's remove it.

macsec: update operstate when lower device changes
Like all other virtual devices (macvlan, vlan), the operstate of a
macsec device should match the state of its lower device. This is done
by calling netif_stacked_transfer_operstate from its netdevice notifier.
We also need to call netif_stacked_transfer_operstate when a new macsec
device is created, so that its operstate is set properly. This is only
relevant when we try to bring the device up directly when we create it.
Radu Rendec proposed a similar patch, inspired from the 802.1q driver,
that included changing the administrative state of the macsec device,
instead of just the operstate. This version is similar to what the
macvlan driver does, and updates only the operstate.

net: sched: gred: pass the right attribute to gred_change_table_def()
gred_change_table_def() takes a pointer to TCA_GRED_DPS attribute,
and expects it will be able to interpret its contents as
struct tc_gred_sopt. Pass the correct gred attribute, instead of
TCA_OPTIONS.
This bug meant the table definition could never be changed after
Qdisc was initialized (unless whatever TCA_OPTIONS contained both
passed netlink validation and was a valid struct tc_gred_sopt...).
Old behaviour:
$ ip link add type dummy
$ tc qdisc replace dev dummy0 parent root handle 7: \
gred setup vqs 4 default 0
$ tc qdisc replace dev dummy0 parent root handle 7: \
gred setup vqs 4 default 0
RTNETLINK answers: Invalid argument
Now:
$ ip link add type dummy
$ tc qdisc replace dev dummy0 parent root handle 7: \
gred setup vqs 4 default 0
$ tc qdisc replace dev dummy0 parent root handle 7: \
gred setup vqs 4 default 0

ptp: drop redundant kasprintf() to create worker name
Building with -Wformat-nonliteral, gcc complains
drivers/ptp/ptp_clock.c: In function ‘ptp_clock_register’:
drivers/ptp/ptp_clock.c:239:26: warning: format not a string literal and no format arguments [-Wformat-nonliteral]
worker_name : info->name);
kthread_create_worker takes fmt+varargs to set the name of the
worker, and that happens with a vsnprintf() to a stack buffer (that is
then copied into task_comm). So there's no reason not to just pass
"ptp%d", ptp->index to kthread_create_worker() and avoid the
intermediate worker_name variable.

net: bridge: remove ipv6 zero address check in mcast queries
Recently a check was added which prevents marking of routers with zero
source address, but for IPv6 that cannot happen as the relevant RFCs
actually forbid such packets:
RFC 2710 (MLDv1):
"To be valid, the Query message MUST
come from a link-local IPv6 Source Address, be at least 24 octets
long, and have a correct MLD checksum."
Same goes for RFC 3810.
And also it can be seen as a requirement in ipv6_mc_check_mld_query()
which is used by the bridge to validate the message before processing
it. Thus any queries with :: source address won't be processed anyway.
So just remove the check for zero IPv6 source address from the query
processing function.

selftests/ftrace: Fix synthetic event test to delete event correctly
Fix the synthetic event test case to remove event correctly.
If redirecting command to synthetic_event file without append
mode, it cleans up all existing events and execute (parse) the
command. This means "delete event" always fails to find the
target event.
Since previous synthetic event has a bug which doesn't return
-ENOENT even if it fails to find the deleting event, this test
passed. But fixing that bug, this test fails because this test
itself has a bug.
This fixes that bug by trying to delete event right after
adding an event, and use append mode redirection ('>>') instead
of normal redirection ('>').

Merge branch 'xarray' of git://git.infradead.org/users/willy/linux-dax
Pull XArray conversion from Matthew Wilcox: "The XArray provides an improved interface to the radix tree data structure, providing locking as part of the API, specifying GFP flags at allocation time, eliminating preloading, less re-walking the tree, more efficient iterations and not exposing RCU-protected pointers to its users. This patch set 1. Introduces the XArray implementation 2. Converts the pagecache to use it 3. Converts memremap to use it The page cache is the most complex and important user of the radix tree, so converting it was most important. Converting the memremap code removes the only other user of the multiorder code, which allows us to remove the radix tree code that supported it. I have 40+ followup patches to convert many other users of the radix tree over to the XArray, but I'd like to get this part in first. The other conversions haven't been in linux-next and aren't suitable for applying yet, but you can see them in the xarray-conv branch if you're interested" * 'xarray' of git://git.infradead.org/users/willy/linux-dax: (90 commits) radix tree: Remove multiorder support radix tree test: Convert multiorder tests to XArray radix tree tests: Convert item_delete_rcu to XArray radix tree tests: Convert item_kill_tree to XArray radix tree tests: Move item_insert_order radix tree test suite: Remove multiorder benchmarking radix tree test suite: Remove __item_insert memremap: Convert to XArray xarray: Add range store functionality xarray: Move multiorder_check to in-kernel tests xarray: Move multiorder_shrink to kernel tests xarray: Move multiorder account test in-kernel radix tree test suite: Convert iteration test to XArray radix tree test suite: Convert tag_tagged_items to XArray radix tree: Remove radix_tree_clear_tags radix tree: Remove radix_tree_maybe_preload_order radix tree: Remove split/join code radix tree: Remove radix_tree_update_node_t page cache: Finish XArray conversion dax: Convert page fault handlers to XArray ... |

modpost: Create macro to avoid variable shadowing
Create DEF_FIELD_ADDR_VAR as a more generic version of the DEF_FIELD_ADD macro, allowing usage of a variable name other than the struct element name. Also, sets DEF_FIELD_ADDR as a specific usage of DEF_FILD_ADDR_VAR in which the var name is the same as the struct element name. Then, makes use of DEF_FIELD_ADDR_VAR to create a variable of another name, in order to avoid variable shadowing.

parisc: Fix A500 boot crash
I believe the following change will fix the cache/TLB inconsistency observed by Meelis. After changing the page table entries, we need to flush the cache and TLB to ensure that we don't have any stale PTE values in the cache or TLB. The alternative patching is done after all CPUs are running. Thus, we need to flush the whole cache and TLB. I included the init section in the range modified by map_pages as suggested by Helge. Some routines in the init section may require patching. Signed-off-by: John David Anglin <dave.anglin@bell.net> Signed-off-by: Helge Deller <deller@gmx.de> |

HID: we do not randomly make new drivers 'default y'
.. even when that "default y" is hidden syntactically as a default !EXPERT it's wrong. The only reason something should be 'default y' is if it used to be built-in, and it was made configurable, and the 'default y' is just retaining the status quo. Altheratively, the hardware for the driver has become _so_ common that it really makes sense for everybody to build it. Finally, one possible reason for 'default y' is because the option is not enabling any new code at all, but is just enabling other options (the networking people do this for vendor options, for example, so that you can disable whole vendors at a time). Clearly, none of these cases hold for the BigBen Interactive Kids' gamepad, and HID_BIGBEN_FF should thus most definitely not default to on for everybody.

tracing: Have stack tracer trace full stack
The stack tracer traces every function call checking the current stack (in non interrupt context), looking for the deepest stack, and saving it when it finds a new max depth. The problem is that it calls save_stack_trace(), and with the new ORC unwinder, it can skip too much. As it looks at the ip of the function call in the backtrace to find where it should start, it doesn't need to skip anything. The stack trace selftest would fail when the kernel was complied with the ORC UNDWINDER enabled. Without skipping functions when doing the stack trace, it now passes again.
