Hey, everyone. I've run into problems starting up my Xen domUs as of
the latest batch of stable updates. Whenever I try to create one, I
get a bunch of block device errors like this:
libxl: error: libxl_device.c:1105:device_backend_callback: Domain 4:unable to

That port does not have an interrupt on TEMT when using
the FIFO mode.

The patch introduce the UART_CAP_TEMT capability which is by default
assigned to all 8250 UART since the code assume that device has the
interrupt on TEMT
In the case where the device does not support it, we calculate the

The series is mainly about the support of 8250 UART without TEMT

it was never merged. Since the last discussion were quite some

Enable drivers to tell ACPI that there's no need to power on a device for
probe. Drivers should still perform this by themselves if there's a need
to. In some cases powering on the device during probe is undesirable, and
this change enables a driver to choose what fits best for it.

Fix a dormant bug in userfaultfd_events_test(), where we did
`return faulting_process(0)` instead of `exit(faulting_process(0))`.
This caused the forked process to keep running, trying to execute any
further test cases after the events test in parallel with the "real"
process.

Describe how UFFDIO_REGISTER_MODE_MINOR and UFFDIO_CONTINUE can be used
to intercept and resolve minor faults. Make it clear that COPY and
ZEROPAGE are used for MISSING faults,
This ioctl is how userspace ought to resolve "minor" userfaults. The
idea is, userspace is notified that a minor fault has occurred. It might
change the contents of the page using its second non-UFFD mapping, or
not. Then, it calls UFFDIO_CONTINUE to tell the kernel "I have ensured

This feature allows userspace to intercept "minor" faults. By "minor"
faults, I mean the following situation:
Let there exist two mappings (i.e., VMAs) to the same page(s) (shared
memory). One of the mappings is registered with userfaultfd (in minor
mode), and the other is not. Via the non-UFFD
As the comment says: for the MINOR fault use case, although the page
might be present and populated in the other (non-UFFD-registered) half
of the shared mapping, it may be out of date, and we explicitly want
userspace to get a minor fault so it can check and potentially update
the page's

Huge pmd sharing for hugetlbfs is racy with userfaultfd-wp because

Many drivers don't want interrupts enabled automatically due to
request_irq(). So they are handling this issue by either way of
the below two:
(1)
irq_set_status_flags(irq, IRQ_NOAUTOEN);
request_irq(dev, irq...);
(2)
request_irq(dev, irq...);
disable_irq(irq);
The code in the second way is silly

upgrading to kernel 5.10.
The laptop's speakers produce no sound. Audio from headphones still
works fine. A quick test is to visit GNOME System Settings -> Sound ->
Output, select Test, click Front Left or Front Right
This patchset added IRQF_NO_AUTOEN for request_irq() and converted
drivers/input to this new API.
Other drivers will be handled afterwards.
