When booting with devicetree, and the devicetree has the cpu-map
node, the topology IDs that are visible from sysfs are generated
with counters. ACPI, on the other hand, uses ACPI table pointer
offsets, which, while guaranteed to be unique, look a bit weird.
Instead, we can generate DT identical to

Asking to change a minor thing in a patch does not really fit
The p9_idpool being used to allocate the IDs uses an IDR to allocate
the IDs ... which we then keep in a doubly-linked list, rather than in
the IDR which allocated them. We can use an IDR directly which saves
two pointers per p9_fid, and a tiny memory allocation per p9_client.

Return NULL instead of ERR_PTR when we can't allocate a FID. The ENOSPC
return value was getting all the way back to userspace, and that's
confusing for a userspace program which isn't expecting read() to tell it
there's no space left on the filesystem. The best error we can return to
indicate a
On a 64-bit system, the wait_queue_head_t is 24 bytes while the pointer
to it is 8 bytes. Growing the p9_req_t by 16 bytes is better than
performing a 24-byte memory allocation.

The 9p code doesn't take advantage of the IDR's ability to store

Add a new coresight device type, which do not belong to any
of the existing types, i.e, source, sink, link etc. A helper
device could be connected to a coresight device, which could
augment the functionality of the coresight device.

Now that we can use a CATU with a scatter gather table, add support
for the TMC ETR to make use of the connected CATU in translate mode.
This is done by adding CATU as new buffer mode.

This patch adds the support for setting up a SG table for use
by the CATU. We reuse the tmc_sg_table to represent the table/data
pages, even though the table format is different.
Similar to ETR SG table, CATU uses a 4KB page size for data buffers
as well as page tables. All table entries are 64bit
Clean up our struct a little bit by using a union instead of
a struct for tracking the subtype of a device.

In some scenarios, we do not want to use CONFIG_NET even though we want
to use CONFIG_KVM. To get this working, and to not pull in more
dependencies, we need to disable CONFIG_TASKSTATS as well.

With the goal of dropping CONFIG_NET, we have to drop the dependency
in the configuration management. Since SECCOMP_FILTER also requires
BPF functionality, which is usually activated by CONFIG_NET, imply
BPF from SECCOMP_FILTER directly.
In case both CONFIG_NET and CONFIG_SECCOMP_FILTER are activa
When we want to use CONFIG_SECCOMP_FILTER without CONFIG_NET, we have
to ensure that the required files that would be pulled in via
CONFIG_NET are compiled when dropping CONFIG_NET.
Here, we could also select CONFIG_NLATTR instead of pulling the file
in explicitly. One could go even one step furth
In the first version of this series, I found a compilation error after
running make randconfig multiple times. I fixed the error, and rebased
the series. Furthermore, this series passed many make randconfig
compilations, as well as a compilation test for multiple architectures
and configurations.

KVM guests on s390 can notify the host of unused pages. This can result
in pte_unused callbacks to be true for KVM guest memory.
If a page is unused (checked with pte_unused) we might drop this page
instead of paging it. This can have side-effects on userfaultd, when the
page in question was alrea
