This GDB script prints the interrupts in the system in the same way that
/proc/interrupts does. This does include the architecture specific part
done by arch_show_interrupts() for x86, ARM, ARM64 and MIPS. Example

If CONFIG_DEBUG_INFO_REDUCED is enabled in the kernel configuration, we
will typically not be able to load vmlinux-gdb.py and will fail with:
Traceback (most recent call last):
File "/home/fainelli/work/buildroot/output/arm64/build/linux-custom/vmlinux-gdb.py", line 25, in <module>

atomic_long_counter_offset = atomic_long_type.get_type()['counter'].bitpos
KeyError: 'counter'
Rather be left wondering what is happening only to find out that reduced
debug information is the cause, raise an eror. This was not typically a
problem until e3c8d33e0d62 ("scripts/gdb: fix 'lx-dmesg' on 32 bits arch")
but it has since then.

Linux makes use of the Radix Tree data structure to store pointers indexed
by integer values. This structure is utilised across many structures in
the kernel including the IRQ descriptor tables, and several filesystems.
This module provides a method to lookup values from a structure given its
head node.
Usage:
The function lx_radix_tree_lookup, must be given a symbol of type struct
radix_tree_root, and an index into that tree.
The object returned is a generic integer value, and must be cast correctly
to the type based on the storage in the data structure.
For example, to print the irq descriptor in the sparse irq_desc_tree at
index 18, try the following:
(gdb) print (struct irq_desc)$lx_radix_tree_lookup(irq_desc_tree, 18)
This script previously existed under commit
e127a73d41ac471d7e3ba950cf128f42d6ee3448 ("scripts/gdb: add a Radix Tree
Parser") and was later reverted with
b447e02548a3304c47b78b5e2d75a4312a8f17e1i (Revert "scripts/gdb: add a
Radix Tree Parser").
This version expects the XArray based radix tree implementation and has
been verified using QEMU/x86 on Linux 6.3-rc5.

This has a slight benefit for x86 and has no effect on other targets.
The benefit to x86 is it change the codegen for setting a node to block
from `mov %r0, %r1; or $RB_BLACK, %r1` to `lea RB_BLACK(%r0), %r1` which
saves an instructions.
In all other cases it just replace ALU with ALU (or -> and) which
perform the same on all machines I am aware of.
Total instructions in rbtree.o:
Before - 802
After - 782
so it saves about 20 `mov` instructions.

"Link:" and "Closes:" tags have to be used with public URLs.
It is difficult to make sure the link is public but at least we can verify
the tag is followed by 'http(s)://'.
With that, we avoid such a tag that is not allowed [1]:
Closes: <number>
Now that we check the "link" tags are followed by a URL, we can relax the
check linked to "Reported-by being followed by a link tag" to only verify
if a "link" tag is present after the "Reported-by" one.

As a follow-up of a previous patch modifying the documentation to allow
using the "Closes:" tag, checkpatch.pl is updated accordingly.
checkpatch.pl now no longer complain when the "Closes:" tag is used by
itself:
commit 76f381bb77a0 ("checkpatch: warn when unknown tags are used for links")
... or after the "Reported-by:" tag:
commit d7f1d71e5ef6 ("checkpatch: warn when Reported-by: is not followed by Link:")

The following commit will allow the use of a similar "link" tag.
Because there is a possibility that other similar tags will be added in
the future and to reduce the number of places where the code will be
modified to allow this new tag, a list with all these "link" tags is now
used.
Two variables are created from it: one to search for such tags and one to
print all tags in a warning message.

When checking if "Reported-by" tag is followed by "Link:", there is no
need to print the next line if there is no next line.
While at it, also mention in this case that the "Link:" tag should be
followed by a URL, similar to the next warning.
By doing that, the code is now similar to what is done above when checking
if the Co-developed-by tag is properly used.

Since v6.3, checkpatch.pl now complains about the use of "Closes:" tags
followed by a link [1]. It also complains if a "Reported-by:" tag is
followed by a "Closes:" one [2].
As detailed in the first patch, this "Closes:" tag is used for a bit of
time, mainly by DRM and MPTCP subsystems. It is used by some bug trackers
to automate the closure of issues when a patch is accepted. It is even
planned to use this tag with bugzilla.kernel.org [3].
The first patch updates the documentation to explain what is this
"Closes:" tag and how/when to use it. The second patch modifies
checkpatch.pl to stop complaining about it.
The DRM maintainers and their mailing list have been added in Cc as they
are probably interested by these two patches as well.
[1] https://lore.kernel.org/all/3b036087d80b8c0e07a46a1dbaaf4ad0d018f8d5.1674217480.git.linux@leemhuis.info/

[3] https://lore.kernel.org/linux-doc/20230315181205.f3av7h6owqzzw64p@meerkat.local/
This patch (of 5):
Making sure a bug tracker is up to date is not an easy task. For example,
a first version of a patch fixing a tracked issue can be sent a long time
after having created the issue. But also, it can take some time to have
this patch accepted upstream in its final form. When it is done, someone
-- probably not the person who accepted the patch -- has to remember about
closing the corresponding issue.
This task of closing and tracking the patch can be done automatically by
bug trackers like GitLab [1], GitHub [2] and hopefully soon [3]
bugzilla.kernel.org when the appropriated tag is used. The two first ones
accept multiple tags but it is probably better to pick one.
According to commit 76f381bb77a0 ("checkpatch: warn when unknown tags are used for links"),
the "Closes" tag seems to have been used in the past by a few people and
it is supported by popular bug trackers. Here is how it has been used in
the past:
$ git log --no-merges --format=email -P --grep='^Closes: http' | \
grep '^Closes: http' | cut -d/ -f3-5 | sort | uniq -c | sort -rn
391 gitlab.freedesktop.org/drm/intel
79 github.com/multipath-tcp/mptcp_net-next
8 gitlab.freedesktop.org/drm/msm
3 gitlab.freedesktop.org/drm/amd
2 gitlab.freedesktop.org/mesa/mesa
1 patchwork.freedesktop.org/series/73320
1 gitlab.freedesktop.org/lima/linux
1 gitlab.freedesktop.org/drm/nouveau
1 github.com/ClangBuiltLinux/linux
1 bugzilla.netfilter.org/show_bug.cgi?id=1579
1 bugzilla.netfilter.org/show_bug.cgi?id=1543
1 bugzilla.netfilter.org/show_bug.cgi?id=1436
1 bugzilla.netfilter.org/show_bug.cgi?id=1427
1 bugs.debian.org/625804
Likely here, the "Closes" tag was only properly used with GitLab and
GitHub. We can also see that it has been used quite a few times (and
still used recently) and this is then not a "random tag that makes no
sense" like it was the case with "BugLink" recently [4]. It has also been
misused but that was a long time ago, when it was common to use many
different random tags.
checkpatch.pl script should then stop complaining about this "Closes" tag.
As suggested by Thorsten [5], if this tag is accepted, it should first be
described in the documentation. This is what is done here in this patch.
To avoid confusion, the "Closes" should be used with any public bug
report. No need to check if the underlying bug tracker supports
automations. Having this tag with any kind of public bug reports allows
bots like regzbot to clearly identify patches fixing a specific bug and
avoid false-positives, e.g. patches mentioning it is related to an issue
but not fixing it. As suggested by Thorsten [6] again, if we follow the
same logic, the "Closes" tag should then be used after a "Reported-by"
one.
Note that thanks to this "Closes" tag, the mentioned bug trackers can also
locate where a patch has been applied in different branches and
repositories. If only the "Link" tag is used, the tracking can also be
done but the ticket will not be closed and a manual operation will be
needed. Also, these bug trackers have some safeguards: the closure is
only done if a commit having the "Closes:" tag is applied in a specific
branch. It will then not be closed if a random commit having the same tag
is published elsewhere. Also in case of closure, a notification is sent
to the owners.

there are no arch-specific implementations.
Remove the unnecessary arch_kexec_kernel_image_load() and make
kexec_image_load_default() static.
No functional change intended.

Patch series "kexec: Remove unnecessary arch hook", v2.
There are no arch-specific things in arch_kexec_kernel_image_load(), so
remove it and just use the generic version.
This patch (of 2):
The x86 implementation of arch_kexec_kernel_image_load() is functionally
identical to the generic arch_kexec_kernel_image_load():
arch_kexec_kernel_image_load # x86
if (!image->fops || !image->fops->load)
return ERR_PTR(-ENOEXEC);
return image->fops->load(image, image->kernel_buf, ...)
arch_kexec_kernel_image_load # generic
kexec_image_load_default
if (!image->fops || !image->fops->load)
return ERR_PTR(-ENOEXEC);
return image->fops->load(image, image->kernel_buf, ...)
Remove the x86-specific version and use the generic
arch_kexec_kernel_image_load(). No functional change intended.

Remove pci_clear_master to simplify the code, the bus-mastering is also
cleared in do_pci_disable_device, like this:
./drivers/pci/pci.c:2197
static void do_pci_disable_device(struct pci_dev *dev)
{
u16 pci_command;
pci_read_config_word(dev, PCI_COMMAND, &pci_command);
if (pci_command & PCI_COMMAND_MASTER) {
pci_command &= ~PCI_COMMAND_MASTER;
pci_write_config_word(dev, PCI_COMMAND, pci_command);
}
pcibios_disable_device(dev);
}.
And dev->is_busmaster is set to 0 in pci_disable_device.

We are observing huge contention on the epmutex during an http
connection/rate test:
83.17% 0.25% nginx [kernel.kallsyms] [k] entry_SYSCALL_64_after_hwframe
[...]
|--66.96%--__fput
|--60.04%--eventpoll_release_file
|--58.41%--__mutex_lock.isra.6
|--56.56%--osq_lock
The application is multi-threaded, creates a new epoll entry for
each incoming connection, and does not delete it before the
connection shutdown - that is, before the connection's fd close().
Many different threads compete frequently for the epmutex lock,
affecting the overall performance.
To reduce the contention this patch introduces explicit reference counting
for the eventpoll struct. Each registered event acquires a reference,
and references are released at ep_remove() time.
The eventpoll struct is released by whoever - among EP file close() and
and the monitored file close() drops its last reference.
Additionally, this introduces a new 'dying' flag to prevent races between
the EP file close() and the monitored file close().
ep_eventpoll_release() marks, under f_lock spinlock, each epitem as dying
before removing it, while EP file close() does not touch dying epitems.
The above is needed as both close operations could run concurrently and
drop the EP reference acquired via the epitem entry. Without the above
flag, the monitored file close() could reach the EP struct via the epitem
list while the epitem is still listed and then try to put it after its
disposal.
An alternative could be avoiding touching the references acquired via
the epitems at EP file close() time, but that could leave the EP struct
alive for potentially unlimited time after EP file close(), with nasty
side effects.
With all the above in place, we can drop the epmutex usage at disposal time.
Overall this produces a significant performance improvement in the
mentioned connection/rate scenario: the mutex operations disappear from
the topmost offenders in the perf report, and the measured connections/rate
grows by ~60%.
To make the change more readable this additionally renames ep_free() to
ep_clear_and_put(), and moves the actual memory cleanup in a separate
ep_free() helper.

ignored. But there are other enums like
ETHTOOL_LINK_MODE_1000baseT_Full_BIT, which are not ignored because of the
not matching '1000baseT' substring.
Add regex to match all ETHTOOL_LINK_MODE enums.

A running x86 UML kernel reports with architecture "i386:x86-64" as it is
a sub-architecture. However, a difference with bare-metal x86 kernels is
in how it manages tasks and the current task struct. To identify that the
inferior is a UML kernel and not bare-metal, check for the existence of
the UML specific symbol "cpu_tasks" which contains the current task
struct.

Improve the average delay precision of getdelay tool to microsecond. When
using the getdelay tool, it is sometimes found that the average delay
except CPU is not 0, but display is 0, because the precison is too low.
For example, see delay average of SWAP below when using ZRAM.
print delayacct stats ON
PID 32915
CPU count real total virtual total delay total delay average
339202 2793871936 9233585504 7951112 0.000ms
IO count delay total delay average
41 419296904 10ms
SWAP count delay total delay average
242589 1045792384 0ms
This wrong display is misleading, so improve the millisecond precision of
the average delay to microsecond just like CPU. Then user would get more
accurate information of delay time.

Pull iommufd fixes from Jason Gunthorpe:
- An invalid VA range can be be put in a pages and eventually trigger
WARN_ON, reject it early
- Use of the wrong start index value when doing the complex batch carry
scheme
- Wrong store ordering resulting in corrupting data used in a later
calculation that corrupted the batch structure during carry
* tag 'for-linus-iommufd' of git://git.kernel.org/pub/scm/linux/kernel/git/jgg/iommufd:
iommufd: Do not corrupt the pfn list when doing batch carry
iommufd: Fix unpinning of pages when an access is present

Pull pwm fixes from Thierry Reding:
"These are some fixes to make sure the PWM state structure is always
initialized to a known state.
Prior to this it could happen in some situations that random data from
the stack would leak into the data structure and cause subtle bugs"
