"Here is a single patch to the LICENSES/ directory to add the CC0
license that is currently used in the kcpuid x86 tool for one of their
files.
This fixes the error that spdxcheck.py currently has with the kcpuid

LICENSES: add CC0-1.0 license text
When CONFIG_SHMEM is not set, the following compiler error occurs:
ld: vmlinux.o: in function `ttm_backup_backup_page':
(.text+0x10363bc): undefined reference to `shmem_writeout'
make[3]: *** [/work/build/trace/nobackup/linux.git/scripts/Makefile.vmlinux:91: vmlinux.unstripped] Error 1
This is due to the replacement of writepage and calling swap_writeout()
and shmem_writeout() directly. The issue is that when CONFIG_SHMEM is
not defined, shmem_writeout() is also not defined.
The function ttm_backup_backup_page() called mapping->a_ops->writepage()
which was then changed to call shmem_writeout() directly.
Even before commit 84798514db ("mm: Remove swap_writepage() and
shmem_writepage()"), it didn't make sense to call anything other than
shmem_writeout() as the ttm_backup deals only with shmem folios.
Have DRM_TTM config option select SHMEM to guarantee that
shmem_writeout() is available.

Pull tracing fixes from Steven Rostedt:
- Fix UAF in module unload in ftrace when there's a bug in the module
If a module is buggy and triggers ftrace_disable which is set when an
anomaly is detected, when it gets unloaded it doesn't free the hooks
into kallsyms, and when a kallsyms lookup is performed it may access
the mod->modname field and crash via UAF.
Fix this by still freeing the mod_maps that are attached to kallsyms
on module unload regardless if ftrace_disable is set or not.
- Do not bother allocating mod_maps for kallsyms if ftrace_disable is
set
- Remove unused trace events
When a trace event or tracepoint is created but not used, it still
creates the code and data structures needed for that trace event.
This just wastes memory.
Remove the trace events that are created but not used. This does not
remove trace events that are created but are not used due configs not
being set. That will be handled later. This only removes events that
have no user under any config.

"Framebuffer Subsystem (fbdev):
- The display's blanking status is now tracked in 'struct fb_info'
- 'framebuffer_alloc()' initializes the blank state to FB_BLANK_UNBLANK
- 'register_framebuffer()' sets the state to 'FB_BLANK_POWERDOWN' if
an 'fb_blank' callback exists, ensuring 'FB_EVENT_BLANK' listeners
correctly see the display being turned on during the first modeset
- The 'FB_EVENT_BLANK' event data now includes both the new and the
old blank states
- 'fb_blank()' has been reworked to return early on errors, without
functional changes, in preparation for further state tracking
improvements
- Fbdev now calls dedicated functions in the backlight subsystems to
notify them of blank state changes, instead of relying on fbdev
event notifiers
- For LCDs, fbdev also calls a dedicated function to notify of mode
changes
- Removed the definitions for the unused fbdev event constants
'FB_EVENT_MODE_CHANGE' and 'FB_EVENT_BLANK' from the header file
Backlight Subsystem:

blank state information provided directly by 'FB_EVENT_BLANK'

helper function, 'backlight_notify_blank()'

function call interface ('backlight_notify_blank()' and
'backlight_notify_blank_all()') for display drivers to update
backlight status
LCD Subsystem:
- Moved the handling of display updates (blank events and mode
changes) from fbdev event notifiers to separate internal helper
functions ('lcd_notify_blank',
'lcd_notify_mode_change')
- Removed support for fbdev events and replaced it with dedicated

LED Backlight Trigger:
- Moved the handling of blank-state updates into a separate internal

trigger of blank state changes

This commit doesn't fix any bug, it is just code cleanup. Use the
function format_dev_t instead of sprintf, because format_dev_t does the
same thing.
Remove the useless memset call.
An unsigned integer can take at most 10 digits, so extend the array size
to 22. (note that because the range of minor and major numbers is limited,
the size 16 could not be exceeded, thus this function couldn't write
beyond string end)

If some of the arguments "check_at_most_once", "ignore_zero_blocks",
"use_fec_from_device", "root_hash_sig_key_desc" were specified more than
once on the target line, a memory leak would happen.
This commit fixes the memory leak. It also fixes error handling in
verity_verify_sig_parse_opt_args.

There's a tiny race condition in dm-mirror. The functions queue_bio and
write_callback grab a spinlock, add a bio to the list, drop the spinlock
and wake up the mirrord thread that processes bios in the list.
It may be possible that the mirrord thread processes the bio just after
spin_unlock_irqrestore is called, before wakeup_mirrord. This spurious
wake-up is normally harmless, however if the device mapper device is
unloaded just after the bio was processed, it may be possible that
wakeup_mirrord(ms) uses invalid "ms" pointer.
Fix this bug by moving wakeup_mirrord inside the spinlock.

When calling cifs_reconnect, before the connection to the
server is reestablished, the code today does a DNS resolution and
updates server->dstaddr.
However, this is not necessary for secondary channels. Secondary
channels use the interface list returned by the server to decide
which address to connect to. And that happens after tcon is reconnected
and server interfaces are requested.

When the server interface info changes (more common in clustered
servers like Azure Files), the per-channel iface gets updated.
However, this did not update the corresponding dstaddr. As a result
these channels will still connect (or try connecting) to older addresses.

cifs_reconnect can be called with a flag to mark the session as needing
reconnect too. When this is done, we expect the connections of all
channels to be reconnected too, which is not happening today.
Without doing this, we have seen bad things happen when primary and
secondary channels are connected to different servers (in case of cloud
services like Azure Files SMB).
This change would force all connections to reconnect as well, not just
the sessions and tcons.

Pull MTD updates from Miquel Raynal:
"A big core MTD change is the introduction of a new class to always
register a master device. This is a problem that has been there
forever: the "master" device was not always present depending on a
number of heuristics such as the presence of fixed partitions and the
absence of a Kconfig symbol to force its presence. This was a problem
for runtime PM operations which might not have the "master" device
available in all situation.
The SPI NAND subsystem has seen the introduction of DTR operations
(the equivalent of DDR transfers), which involved quite a few
preparation patches for clarifying macro names.
In the raw NAND subsystem, the brcmnand driver has been "fixed" for
old legacy SoCs with an update of the ->exec_op() hook, there has been
the introduction of a new controller driver named Loongson-1, and the
Qualcomm driver has received quite a few misc fixes as well as a new
compatible.
Finally, Macornix SPI NOR entries have been cleaned-up and some SFDP
table fixups for Macronix MX25L3255E have been merged.
Aside from this, there is the usual load of misc improvement, fixes,
and yaml conversion"
