Please run this past the swait authors. It is supposed to be a simple
and self-contained API so I'd expect this patch to be seen critical.
You might be better off to just use the normal complex waitqueues if

This patch is to introduce the framebuffer decoder which can decode guest

Add VFIO_DEVICE_QUERY_GFX_PLANE ioctl command to let user query and get

1) Either DMABUF or REGION flag. Vendor driver returns a plane_info

The warning of slow allocation has been removed, this is
a other way to fetch that information. But you need
to enable the trace. The exit function also returns
information about the number of retries, how long
it was stalled and failure reason if that happened.

Hello Nick & Binutils developers,
It would appear that recent changes in the binutils assembler (perhaps
52a86f843b6dee1de9977293da9786649b146b05? perhaps not?) have broken
the kernel when compiled in thumb2 mode. We currently do not have a
way of working around your breaking changes without addin
Hello, Atish, Peter, all.
I have a question about if a task's nr_cpus_allowed is 1.
In that scenario we do not call select_task_rq. Therefore
even thought a task "p" is placed on idle CPU that CPU
will not be marked as claimed for wake-up.
What do you think about adding per_cpu(claim_wakeup, cpu)
added error checks in acp dma driver

Hi all,
this is a second round of patches to introduce memory hotplug and
hotremove support for arm64. It builds on the work previously published at
[1] and it implements the feedback received in the first round of reviews.
The patchset applies and has been tested on commit bebc6082da0a ("Linux

Introduces memory hotplug functionality (hot-add) for arm64.
Changes v1->v2:
- swapper pgtable updated in place on hot add, avoiding unnecessary copy:
all changes are additive and non destructive.
- stop_machine used to updated swapper on hot add, avoiding races
- checking if pagealloc is unde
Commit 242831eb15a0 ("Memory hotplug / ACPI: Simplify memory removal")

reaches remove_memory the corresponding memory has been already

the assumption held.
This assumption, however, is not
When hot-removing memory we need to free vmemmap memory.
However, depending on the memory is being removed, it might
not be always possible to free a full vmemmap page / huge-page
because part of it might still be used.
