The vfio_ap device driver registers a group notifier with VFIO when the
file descriptor for a VFIO mediated device for a KVM guest is opened to
receive notification that the KVM pointer is set (VFIO_GROUP_NOTIFY_SET_KVM
event). When the KVM pointer is set, the vfio_ap driver takes the

This patch refactors the vfio_ap device driver to use the AP bus's

information about a queue that is bound to the vfio_ap device driver.
The bus's ap_get_qdev() function retrieves the queue device from a

The matrix of adapters and domains configured in a guest's APCB may

that is or
The current implementation does not allow assignment of an AP adapter or
domain to an mdev device if each APQN resulting from the assignment
does not reference an AP queue device that is bound to the vfio_ap device
driver. This patch allows assignment of AP resources to the matrix mdev as
long as
Introduces a new driver callback to prevent a root user from unbinding
an AP queue from its device driver if the queue is in use. The callback

driver. If
The APCB is a field within the CRYCB that provides the AP configuration

Hello Linus
Sorry for the 2nd pull request, but this is a fairly important fix
for the privilege handling of smackfs in the face of io_uring. The
novel use of kernel threads in io_uring invalidated an long standing
assumption regarding the privilege of kernel threads. The fix is
simple and safe.

Newer AMD processors have a feature to virtualize the use of the
SPEC_CTRL MSR. A hypervisor may wish to impose speculation controls on
guest execution or a guest may want to impose its own speculation
controls. Therefore, the processor implements both host and guest
versions of SPEC_CTRL.
Newer AMD processors have a feature to virtualize the use of the
SPEC_CTRL MSR. Presence of this feature is indicated via CPUID
function 0x800A_EDX[20]: GuestSpecCtrl. When preset, the SPEC_CTRL
MSR is automatically virtualized.

Hi,
This patch series cleans up all the checkpatch.pl related warnings in the
wlan-ng module. I tried to resolve those issues in a sensible manner.
Johannes Czekay (6):
wlan-ng: clean up line ending
wlan-ng: clean up spinlock_t definition
wlan-ng: rename macros
wlan-ng: clean up line
This patch cleans up a "spinlock_t definition without comment" warning in
hfa384x.h.

This patch renames some of the macros defined in "p80211metadef.h" in
order to fix some of the line length related warnings from checkpatch.
Since these macros are very long, fitting them within the given line
length would be really hard otherwise.

This patch cleans up two "macro argument reuse" warnings by checkpatch.
This should also make the code much more readable.

This adds driver for the Qualcomm QCA8072 and QCA8075 PHY-s.
They are 2 or 5 port IEEE 802.3 clause 22 compliant
10BASE-Te, 100BASE-TX and 1000BASE-T PHY-s.
They feature 2 SerDes, one for PSGMII or QSGMII connection with MAC,
while second one is SGMII for connection to MAC or fiber.
