Alexander Shishkin b44a2b53be perf/x86/intel/pt: Fix a refactoring bug
Commit 066450be41 ("perf/x86/intel/pt: Clean up the control flow
in pt_pmu_hw_init()") changed attribute initialization so that
only the first attribute gets initialized using
sysfs_attr_init(), which upsets lockdep.

This patch fixes the glitch so that all allocated attributes are
properly initialized thus fixing the lockdep warning reported by
Tvrtko and Imre.

Clemens Ladisch ea114fc27d ALSA: usb-audio: fix missing input volume controls in MAYA44 USB(+)
The driver worked around an error in the MAYA44 USB(+)'s mixer unit
descriptor by aborting before parsing the missing field.  However,
aborting parsing too early prevented parsing of the other units
connected to this unit, so the capture mixer controls would be missing.

Fix this by moving the check for this descriptor error after the parsing
of the unit's input pins.

Sasha Levin 161f873b89 vfs: read file_handle only once in handle_to_path
We used to read file_handle twice.  Once to get the amount of extra
bytes, and once to fetch the entire structure.

This may be problematic since we do size verifications only after the
first read, so if the number of extra bytes changes in userspace between
the first and second calls, we'll have an incoherent view of
file_handle.

Instead, read the constant size once, and copy that over to the final
structure without having to re-read it again.

Andy Lutomirski 425be5679f x86/asm/irq: Stop relying on magic JMP behavior for early_idt_handlers
The early_idt_handlers asm code generates an array of entry
points spaced nine bytes apart.  It's not really clear from that
code or from the places that reference it what's going on, and
the code only works in the first place because GAS never
generates two-byte JMP instructions when jumping to global
labels.

Clean up the code to generate the correct array stride (member size)
explicitly. This should be considerably more robust against
screw-ups, as GAS will warn if a .fill directive has a negative
count.  Using '. =' to advance would have been even more robust
(it would generate an actual error if it tried to move
backwards), but it would pad with nulls, confusing anyone who
tries to disassemble the code.  The new scheme should be much
clearer to future readers.

While we're at it, improve the comments and rename the array and
common code.

Binutils may start relaxing jumps to non-weak labels.  If so,
this change will fix our build, and we may need to backport this
change.

Joerg Roedel 2d0ec7a19b Revert "iommu/amd: Don't allocate with __GFP_ZERO in alloc_coherent"
This reverts commit 5fc872c732.

The DMA-API does not strictly require that the memory
returned by dma_alloc_coherent is zeroed out. For that
another function (dma_zalloc_coherent) should be used. But
all other x86 DMA-API implementation I checked zero out the
memory, so that some drivers rely on it and break when it is
not.

It seems the (driver-)world is not yet ready for this
change, so revert it.

This is a 1:1 conversion with respect to schedule_timeout() to the

consolidation to improve readability. The hard coded timeout of 10
jiffies is HZ dependent which it should not be, so it is converted
with msecs_to_jiffies.

In order to remove bus_info, we need to migrate vbus_hdr_info into
the public namespace of visor_device.  Because the struct is private,
we use a void * to hide the contents.

As a result, we need to allocate vbus_hdr_info and manage it.

Also work around vbus_valid, as that variable will not be used
in the public namespace.

Don Zickus 0274b5aec1 staging: unisys: Convert pending_msg_hdr to a pointer
In order for bus/dev_info structs to become public structs, one
element, pending_msg_hdr, needs to become opaque.  This is to keep
all the internals of the controlvm struct private to the bus layer.

So a simple conversion of embedding the pending_msg_hdr struct into
a pointer is done.  The rest of the patch is the fallout.

The rules are modified slightly.  Instead of relying on the 'id' to be
CONTROLVM_INVALID to indicate invalid, just use the pointer set to NULL.

In addition, because bus/dev_info can be NULL and we still need to send
a
response, pass pending_msg_hdr to all 'responders' instead of bus/

That change causes some fallout in the success case.  Instead of setting
state
bits and clearing info in the responders, do all that magic in the
responder
wrappers.

Don Zickus b32c4997c0 staging: unisys: Move channel creation up the stack
Instead of creating a channel struct to temporarily hold the channel
info and passing it through multiple functions until the device is
created, just create the channel from the start.

This allows us to remove the channel_info struct.

I noticed 'chan_info.addr_type' was not being used, so I just deleted it.

Arnd Bergmann 057d1e9793 staging: wilc1000: fix const cast warnings
The wilc1000 driver produces a lot of warnings about invalid
casts between const and non-const variables. This reworks
the code to avoid all those warnings, by marking variables
and function arguments const.

A lot of the types use WILC_Uint8, I change them to const u8
for style reasons, as I'm touching them anyway.

Arnd Bergmann 83383ea33c staging: wilc1000: remove semaphore wrapper
The various semaphore functions all directly translate into
sema_init(), down() and up(), so we can just remove the API.

This is a mostly automated conversion using simple sed scripts,
plus some manual changes to account for down() returning no
error.

As a positive side-effect, down() no longer hangs after
receiving a signal, as the original code did by looping around
down_interruptible.

The semaphores still need to be turned into mutexes as a
follow-up step.

The driver has a simple wrapper around timer_list, and an

This removes support for the periodic timer and simplifies
the code around timers.
