[PATCH AUTOSEL 6.1 01/12] arm64: dts: rockchip: fix USB regulator on ROCK64

[Sasha Levin]

From: Lorenz Brun <lorenz@brun.one>

[ Upstream commit 03633c4ef1fb5ee119296dfe0c411656a9b5e04f ]

Currently the ROCK64 device tree specifies two regulators, vcc_host_5v
and vcc_host1_5v for USB VBUS on the device. Both of those are however
specified with RK_PA2 as the GPIO enabling them, causing the following
error when booting:

  rockchip-pinctrl pinctrl: pin gpio0-2 already requested by vcc-host-5v-regulator; cannot claim for vcc-host1-5v-regulator
  rockchip-pinctrl pinctrl: pin-2 (vcc-host1-5v-regulator) status -22
  rockchip-pinctrl pinctrl: could not request pin 2 (gpio0-2) from group usb20-host-drv  on device rockchip-pinctrl
  reg-fixed-voltage vcc-host1-5v-regulator: Error applying setting, reverse things back

Looking at the schematic, there are in fact three USB regulators,
vcc_host_5v, vcc_host1_5v and vcc_otg_v5. But the enable signal for all
three is driven by Q2604 which is in turn driven by GPIO_A2/PA2.

Since these three regulators are not controllable separately, I removed
the second one which was causing the error and added labels for all
rails to the single regulator.

[PATCH AUTOSEL 6.1 02/12] tracing/user_events: Prevent same name but different args event

[Sasha Levin]

From: sunliming <sunliming@kylinos.cn>

[ Upstream commit ba470eebc2f6c2f704872955a715b9555328e7d0 ]

User processes register name_args for events. If the same name but different
args event are registered. The trace outputs of second event are printed
as the first event. This is incorrect.

Return EADDRINUSE back to the user process if the same name but different args
event has being registered.

[PATCH AUTOSEL 6.1 03/12] tracing/user_events: Handle matching arguments that is null from dyn_events

[Sasha Levin]

From: sunliming <sunliming@kylinos.cn>

[ Upstream commit cfac4ed7279d056df6167bd665e460787dc9e0c4 ]

When A registering user event from dyn_events has no argments, it will pass the
matching check, regardless of whether there is a user event with the same name
and arguments. Add the matching check when the arguments of registering user
event is null.

[PATCH AUTOSEL 6.1 04/12] tracing/user_events: Fix the incorrect trace record for empty arguments events

[Sasha Levin]

From: sunliming <sunliming@kylinos.cn>

[ Upstream commit 6f05dcabe5c241d066ec472cf38ac8b84f8c9c6f ]

The user_events support events that has empty arguments. But the trace event
is discarded and not really committed when the arguments is empty. Fix this
by not attempting to copy in zero-length data.

I've been experiencing some intermittent crashes down in the display

    amdgpu 0000:30:00.0: [drm] Failed to create MST payload for port 000000006d3a3885: -5

...followed by an Oops due to a NULL pointer dereference.

Switch to using mgr->dev instead of state->dev since "state" can be
NULL in some cases.

[PATCH AUTOSEL 6.1 12/12] workqueue: clean up WORK_* constant types, clarify masking

[Sasha Levin]

From: Linus Torvalds <torvalds@linux-foundation.org>

[ Upstream commit afa4bb778e48d79e4a642ed41e3b4e0de7489a6c ]

Dave Airlie reports that gcc-13.1.1 has started complaining about some
of the workqueue code in 32-bit arm builds:

  kernel/workqueue.c: In function ‘get_work_pwq’:
  kernel/workqueue.c:713:24: error: cast to pointer from integer of different size [-Werror=int-to-pointer-cast]
    713 |                 return (void *)(data & WORK_STRUCT_WQ_DATA_MASK);
        |                        ^
  [ ... a couple of other cases ... ]

and while it's not immediately clear exactly why gcc started complaining
about it now, I suspect it's some C23-induced enum type handlign fixup in
gcc-13 is the cause.

Whatever the reason for starting to complain, the code and data types
are indeed disgusting enough that the complaint is warranted.

The wq code ends up creating various "helper constants" (like that
WORK_STRUCT_WQ_DATA_MASK) using an enum type, which is all kinds of
confused.  The mask needs to be 'unsigned long', not some unspecified
enum type.

To make matters worse, the actual "mask and cast to a pointer" is
repeated a couple of times, and the cast isn't even always done to the
right pointer, but - as the error case above - to a 'void *' with then
the compiler finishing the job.

That's now how we roll in the kernel.

So create the masks using the proper types rather than some ambiguous
enumeration, and use a nice helper that actually does the type
conversion in one well-defined place.

Incidentally, this magically makes clang generate better code.  That,
admittedly, is really just a sign of clang having been seriously
confused before, and cleaning up the typing unconfuses the compiler too.
