Without this the generic cdc_ether grabs the device,

This driver uses interfaces from linux/of.h and linux/property.h but
relies on implict inclusion of those headers which means that changes in
other headers could break the build, as happened in -next for arm today.
Add a explicit includes.

"These fix two issues related to IOAPIC hotplug, an overzealous build
optimization that prevents the function graph tracer from working with

Specifics:
- drop the unconditional setting of the '-Os' gcc flag from the ACPI

ACPI subsystem (Josh Poimboeuf).
- add missing synchronize_rcu() to ghes_remove() which removes an
element from an RCU-protected list, but fails to synchronize it
properly afterward (James Morse).

initialization in setup_res() and the creation of platform device

erratum 44 sets the "qdf2400_e44_present" global variable if the

kbuild test robot reported a non-static variable name collision between

Commit c2a6bbaf0c5f (ACPI / scan: Prefer devices without _HID/_CID
for _ADR matching) added a list_empty(&adev->pnp.ids) check to
find_child_checks() so as to catch situations in which the ACPI
core attempts to decode _ADR for a device having a _HID too which
is strictly against the spec. However, it overlooked the fact that
the adev->pnp.ids list for the devices taken into account by
find_child_checks() may contain device IDs set internally by the
kernel, like "LNXVIDEO" (thanks to Zhang Rui for that realization),
and it broke the enumeration of those devices as a result.
To unbreak it, replace the overly coarse grained list_empty()
check with a much more precise check against the pnp.type.platform_id
flag which is only set for devices having a _HID (that's how it
should be done from the start, as having both _ADR and _CID is
actually permitted).

In commit d0aeaa83f0b0f7a92615bbdd6b1f96812f7dcfd2 ("serial: exar:
split out the exar code from 8250_pci") the exar driver got its own
Kconfig. However the text for the new option was never changed from
the original 8250_PCI text, and hence it appears confusing when you
get asked the same question twice:
8250/16550 PCI device support (SERIAL_8250_PCI) [Y/n/m/?] (NEW)
8250/16550 PCI device support (SERIAL_8250_EXAR) [Y/n/m] (NEW)
Adding to the confusion, is that there is no help text for this new
option to indicate it is specific to a certain family of cards.
Fix both issues at the same time, as well as the space vs. tab issues
introduced in the same commit.

The reference manual for the i.MX28 recommends to calculate the divisor
as
divisor = (UARTCLK * 32) / baud rate, rounded to the nearest integer
, so let's do this. For a typical setup of UARTCLK = 24 MHz and baud
rate = 115200 this changes the divisor from 6666 to 6667 and so the
actual baud rate improves from 115211.521 Bd (error ≅ 0.01 %) to
115194.240 Bd (error ≅ 0.005 %).

Commit 4257e08 ("dm raid: support to change bitmap region size")
introduced a bitmap resize call during preresume phase. User can create
a DM device with "raid" target configured as raid1 with no metadata
devices to hold superblock/bitmap info. It can be achieved using the
following sequence:
truncate -s 32M /dev/shm/raid-test
LOOP=$(losetup --show -f /dev/shm/raid-test)
dmsetup create raid-test-linear0 --table "0 1024 linear $LOOP 0"
dmsetup create raid-test-linear1 --table "0 1024 linear $LOOP 1024"
dmsetup create raid-test --table "0 1024 raid raid1 1 2048 2 - /dev/mapper/raid-test-linear0 - /dev/mapper/raid-test-linear1"
This results in the following crash:

The raid_preresume() function incorrectly assumes that the raid_set has
a bitmap enabled if RT_FLAG_RS_BITMAP_LOADED is set. But
RT_FLAG_RS_BITMAP_LOADED is getting set in __load_dirty_region_bitmap()
even if there is no bitmap present (and bitmap_load() happily returns 0
even if a bitmap isn't present). So the only way forward in the
near-term is to check if the bitmap is present by seeing if
mddev->bitmap is not NULL after bitmap_load() has been called.
By doing so the above NULL pointer is avoided.

git://git.kernel.org/pub/scm/linux/kernel/git/maz/arm-platforms into irq/urgent
Pull irqchip fixes from Marc Zyngier
- Fix mvebu-odmi dependency selection
- Fix mips-gic virtual/hw mapping
|
|
Commit 4cfffcfa5106 ("irqchip/mips-gic: Fix local interrupts") added
mapping of several local interrupts during initialisation of the gic
driver. This associates virq numbers with these interrupts.
Unfortunately, as not all of the interrupts are mapped in hardware
order, when drivers subsequently request these interrupts they conflict
with the mappings that have already been set up. For example, this
manifests itself in the gic clocksource driver, which fails to probe
with the message:
clocksource: GIC: mask: 0xffffffffffffffff max_cycles: 0x7350c9738,
max_idle_ns: 440795203769 ns
GIC timer IRQ 25 setup failed: -22
This is because virq 25 (the correct IRQ number specified via device
tree) was allocated to the PERFCTR interrupt (and 24 to the timer, 26 to
the FDC). To fix this, map all of these local interrupts in the hardware
order so as to associate their virq numbers with the correct hw
interrupts.

SDIO cards may need clock to send the card interrupt to the host.
On a cherrytrail tablet with a RTL8723BS wifi chip, without this patch
pinging the tablet results in:

A use-after-free was found using KASAN. In brcmf_p2p_del_if() the virtual
interface is removed using call to brcmf_remove_interface(). After that
the virtual interface instance has been freed and should not be referenced.
Solve this by storing the nl80211 iftype in local variable, which is used
in a couple of places anyway.

In vmw_surface_define_ioctl(), the 'num_sizes' is the sum of the
'req->mip_levels' array. This array can be assigned any value from
the user space. As both the 'num_sizes' and the array is uint32_t,
it is easy to make 'num_sizes' overflow. The later 'mip_levels' is
used as the loop count. This can lead an oob write. Add the check of
'req->mip_levels' to avoid this.

On recent kernels, calling drm_ht_remove triggers a might_sleep() warning
from within vfree(). So avoid calling it from atomic context. The use-cases
we fix here are both from destructors so there should be no concurrent
use of the hash tables.

Previously, when a surface was opened using a legacy (non prime) handle,
it was verified to have been created by a client in the same master realm.
Relax this so that opening is also allowed recursively if the client
already has the surface open.
This works around a regression in svga mesa where opening of a shared
surface is used recursively to obtain surface information.

In vmw_get_cap_3d_ioctl(), a user can supply 0 for a size that is

Commit a544c619a54b ("HID: wacom: do not attempt to switch mode
while in probe") introduces delayed work for querying (setting the
mode) on all tablets. Bamboo Touch (056a:00d0) has a ghost
interface which claims to be a pen device. Though this device can
be removed, we have to set the mode on the ghost pen interface
before we remove it. After the aforementioned delay was introduced
the device was being removed before the mode setting could be
executed.

A previous commit (below) adds a check for already probed interfaces to
Wacom's matching heuristic. Unfortunately this causes the Bamboo Pen
(CTL-460) to match itself to its 'ghost' touch interface. After
subsequent changes to the driver this match to the ghost causes the
kernel to crash. This patch avoids calling wacom_add_shared_data()
for the BAMBOO_PEN's ghost touch interface.

On Bay Trail / Cherry Trail systems with a LID switch, the LID switch is
often connect to a gpioint handled by an _IAE event handler.
Before this commit such systems would not wake up when opening the lid,
requiring the powerbutton to be pressed after opening the lid to wakeup.
Note that Bay Trail / Cherry Trail systems use suspend-to-idle, so
the interrupts are generated anyway on those lines on lid switch changes,
but they are treated by the IRQ subsystem as spurious while suspended if
not marked as wakeup IRQs.
This commit calls enable_irq_wake() for _IAE GpioInts with a valid
event handler which have their Wake flag set. This fixes such systems
not waking up when opening the lid.
