Pull removal of most of fs/compat_ioctl.c from Arnd Bergmann:
"As part of the cleanup of some remaining y2038 issues, I came to
fs/compat_ioctl.c, which still has a couple of commands that need
support for time64_t.In completely unrelated work, I spent time on cleaning up parts of
this file in the past, moving things out into drivers instead.After Al Viro reviewed an earlier version of this series and did a lot
more of that cleanup, I decided to try to completely eliminate the
rest of it and move it all into drivers.This series incorporates some of Al's work and many patches of my own,
but in the end stops short of actually removing the last part, which
is the scsi ioctl handlers. I have patches for those as well, but they
need more testing or possibly a rewrite"* tag 'compat-ioctl-5.5' of git://git.kernel.org:/pub/scm/linux/kernel/git/arnd/playground: (42 commits)

Each of these drivers has a copy of the same trivial helper function to
convert the pointer argument and then call the native ioctl handler.We now have a generic implementation of that, so use it.

Pull staging / IIO driver updates from Greg KH:
"Here is the big staging and iio driver update for 5.2-rc1.Lots of tiny fixes all over the staging and IIO driver trees here,
along with some new IIO drivers.The "counter" subsystem was added in here as well, as it is needed by
the IIO drivers and subsystem.Also we ended up deleting two drivers, making this pull request remove
a few hundred thousand lines of code, always a nice thing to see. Both
of the drivers removed have been replaced with "real" drivers in their
various subsystem directories, and they will be coming to you from
those locations during this merge window.There are some core vt/selection changes in here, that was due to some
cleanups needed for the speakup fixes. Those have all been acked by
the various subsystem maintainers (i.e. me), so those are ok.We also added a few new drivers, for some odd hardware, giving new
developers plenty to work on with basic coding style cleanups to come
in the near future.Other than that, nothing unusual here.
All of these have been in linux-next for a while with no reported
issues, other than an odd gcc warning for one of the new drivers that
should be fixed up soon"[ I fixed up the warning myself - Linus ]

Using scripts/coccinelle/api/stream_open.cocci added in 10dce8af3422
("fs: stream_open - opener for stream-like files so that read and write
can run simultaneously without deadlock"), search and convert to
stream_open all in-kernel nonseekable_open users for which read and
write actually do not depend on ppos and where there is no other methods
in file_operations which assume @offset access.I've verified each generated change manually - that it is correct to convert -
and each other nonseekable_open instance left - that it is either not correct
to convert there, or that it is not converted due to current stream_open.cocci
limitations. The script also does not convert files that should be valid to
convert, but that currently have .llseek = noop_llseek or generic_file_llseek
for unknown reason despite file being opened with nonseekable_open (e.g.
drivers/input/mousedev.c)Among cases converted 14 were potentially vulnerable to read vs write deadlock

currently detects only "wait_event*" as blocking.Cc: Michael Kerrisk

When setting output power level called, the power level should be
checked by power amplifier level register and high power option. There
was todo about it. Add some variables for checking power level range.
The values that used for checking high power or minimum power are from
rf69 datasheets. The maximum power level is always same regardless of
mode.Signed-off-by: Sidong Yang

The device structure contains a useless non-atomic users counter which
is subject to race conditions. It has probably been created to handle
the case where remove is executed while operations are still executing
on open fds but this will never happen because of reference counts.Drop the users counter and move rx buffer {de,}allocation to probe()
and remove(). Remove associated dead code from open() and release().

In the PI433_IOC_WR_TX_CFG case in pi433_ioctl, instance->tx_cfg is
modified viacopy_from_user(&instance->tx_cfg, argp, sizeof(struct pi433_tx_cfg)))
without any kind of synchronization. In the case where two threads
would execute this same command concurrently the tx_cfg field might
enter in an inconsistent state.Additionally: if ioctl(PI433_IOC_WR_TX_CFG) and write() execute
concurrently the tx config might be modified while it is being
copied to the fifo, resulting in potential data corruption.Fix: Get instance->tx_cfg_lock before modifying tx config in the
PI433_IOC_WR_TX_CFG case in pi433_ioctl.Also, do not copy data directly from user space to instance->tx_cfg.
Instead use a temporary buffer allowing future checks for correctness
of copied data and simpler code.Signed-off-by: Hugo Lefeuvre
