On an Intel NUC6iSYK, no IR is reported after a receive overflow.
When a receiver overflow occurs, this condition is only cleared by
reading the fifo. Make sure we read anything in the fifo.

This driver is a port of the lirc_sir driver to rc-core. However, for
this driver I could not find any hardware to test, so it was done without
testing. This is a mistake.
There are clear bugs in the code. For example the two arguments
to ktime_us_delta() are reversed, which means the result is garbage.
The driver has been in the kernel for four years, and noone has ever
reported an issue. So, remove this driver.

If the IR Toy is receiving IR while a transmit is done, it may end up
hanging. We can prevent this from happening by re-entering sample mode
just before issuing the transmit command.

Syzkaller reported a warning called "rcu detected stall in dummy_timer".
The error seems to be an error in mceusb_dev_recv(). In the case of
-EPROTO error, the routine immediately resubmits the URB. Instead it
should return without resubmitting URB.

Add ability for users to specify custom u64 value (bpf_cookie) when creating
BPF link for perf_event-backed BPF programs (kprobe/uprobe, perf_event,
tracepoints).
This is useful for cases when the same BPF program is used for attaching and
processing invocation of different tracepoints/kprobes/uprobes in a generic
fashion, but such that each invocation is distinguished from each other (e.g.,
BPF program can look up additional information associated with a specific
kernel function without having to rely on function IP lookups). This enables
new use cases to be implemented simply and efficiently that previously were
possible only through code generation (and thus multiple instances of almost
identical BPF program) or compilation at runtime (BCC-style) on target hosts
(even more expensive resource-wise). For uprobes it is not even possible in
some cases to know function IP before hand (e.g., when attaching to shared
library without PID filtering, in which case base load address is not known
for a library).
This is done by storing u64 bpf_cookie in struct bpf_prog_array_item,
corresponding to each attached and run BPF program. Given cgroup BPF programs
already use two 8-byte pointers for their needs and cgroup BPF programs don't
have (yet?) support for bpf_cookie, reuse that space through union of
cgroup_storage and new bpf_cookie field.
Make it available to kprobe/tracepoint BPF programs through bpf_trace_run_ctx.
This is set by BPF_PROG_RUN_ARRAY, used by kprobe/uprobe/tracepoint BPF
program execution code, which luckily is now also split from
BPF_PROG_RUN_ARRAY_CG. This run context will be utilized by a new BPF helper
giving access to this user-provided cookie value from inside a BPF program.
Generic perf_event BPF programs will access this value from perf_event itself
through passed in BPF program context.

Turn BPF_PROG_RUN into a proper always inlined function. No functional and
performance changes are intended, but it makes it much easier to understand
what's going on with how BPF programs are actually get executed. It's more
obvious what types and callbacks are expected. Also extra () around input
parameters can be dropped, as well as `__` variable prefixes intended to avoid
naming collisions, which makes the code simpler to read and write.
This refactoring also highlighted one extra issue. BPF_PROG_RUN is both
a macro and an enum value (BPF_PROG_RUN == BPF_PROG_TEST_RUN). Turning
BPF_PROG_RUN into a function causes naming conflict compilation error. So
rename BPF_PROG_RUN into lower-case bpf_prog_run(), similar to
bpf_prog_run_xdp(), bpf_prog_run_pin_on_cpu(), etc. All existing callers of
BPF_PROG_RUN, the macro, are switched to bpf_prog_run() explicitly.

Use DEVICE_ATTR_RW() helper macro instead of DEVICE_ATTR(), which is
simpler and more readable.
Due to the names of the read and write functions of the sysfs attribute is
normalized, there is a natural association.

Instead of using U+2013 ('–'): EN DASH, let's just use an
hyphen there, as this was probably introduced by some cut-and-paste
from some other place.

I came across a randconfig build failure from one driver
that only depends on CONFIG_USB_ARCH_HAS_HCD but fails when
built without CONFIG_USB:
ld: drivers/media/rc/ir_toy.o: in function `irtoy_disconnect':
ir_toy.c:(.text+0x24): undefined reference to `usb_kill_urb'
ld: ir_toy.c:(.text+0x2c): undefined reference to `usb_free_urb'
ld: ir_toy.c:(.text+0x34): undefined reference to `usb_kill_urb'
ld: ir_toy.c:(.text+0x3c): undefined reference to `usb_free_urb'
Upon a closer look, I find that a lot of the other drivers
'select USB' rather than stating 'depends on USB' as is common
for most subsystems. I also find that all except one driver
have an extra 'depends on RC_CORE' that is already implied by
the top-level 'if RC_CORE' check.
Clean up both by reducing the dependencies to the required set.

The Asus PN50 has 16 byte io region for the ITE8708 in its DSDT, which

The in_use variable is set to true when a lirc file is opened, and ir
transmit can only be done by writing to a lirc file descriptor. As a
result when in_use is read, it is always true, so we might as well remove

The carrier, duty cycle etc are not device dependent, and they can be
changed at runtime. By moving them into the allocated struct, we can make
the device specific structures smaller, and we no longer need to copy
the struct.
