definitions of avanti_mv and noname_mv (and associated ALIAS_MV)
are conditional upon the wrong thing - it should be
CONFIG_ALPHA_{AVANTI,NONAME}_CH, not CONFIG_ALPHA_{AVANTI,NONAME}.
The former is a system type; the latter is for the bits shared
by AVANTI with XL and NONAME with ALPHA_BOOK1 resp.
We want all those machine vectors defined (but not aliased - see
ALIAS_MV() definition for details) for GENERIC build; for
system-specfic builds we want only one mv, so avanti_mv should *not*
be there for XL; it certainly should not be have alpha_mv aliased to
it on such config - xl_mv will be there and alpha_mv can't be aliased
to both of those.
The same goes for Noname vs. Alphabook1.

On alpha str{n,}{cpy,cat}() implementations are playing
fun games with shared chunks of code. The problem is, they are
using direct branches and need to be next to each other.
Currently it's done by building them in separate object
files, then using ld -r to link those together. Unfortunately,
genksyms machinery has no idea what to do with that - we have
generated in arch/alpha/lib/.strcat.S.cmd, but there's nothing
to propagate that into .stycpy.S.cmd, so modpost doesn't find
anything for those symbols, resulting in
WARNING: modpost: EXPORT symbol "strcpy" [vmlinux] version generation failed, symbol will not be versioned.
Is "strcpy" prototyped in <asm/asm-prototypes.h>?
WARNING: modpost: EXPORT symbol "strcat" [vmlinux] version generation failed, symbol will not be versioned.

WARNING: modpost: EXPORT symbol "strncat" [vmlinux] version generation failed, symbol will not be versioned.
Is "strncat" prototyped in <asm/asm-prototypes.h>?
spew on modversion-enabled builds (all 4 functions in question
are in fact prototyped in asm-prototypes.h)
Fixing doesn't require messing with kbuild, thankfully -
just build one object (i.e. have sty{n,}cpy.S with includes of relevant
*.S instead of playing with ld -r) and that's it.

Take scr_memmove() out of line, make both it and scr_memcpyw()
conditional upon VGA_CONSOLE or MDA_CONSOLE (if neither is
selected, we are certain to be working with the kernel-allocated
buffer rather than VRAM and defaults will work just fine).
That allows to clean vt_buffer.h, but that's a separate story

Sysctl handlers are not supposed to modify the ctl_table passed to them.
Adapt the logic to work with a temporary variable, similar to how it is
done in other parts of the kernel.
This is also a prerequisite to enforce the immutability of the argument
through the callbacks.

There is a race condition between l2cap_chan_timeout() and
l2cap_chan_del(). When we use l2cap_chan_del() to delete the
channel, the chan->conn will be set to null. But the conn could
be dereferenced again in the mutex_lock() of l2cap_chan_timeout().
As a result the null pointer dereference bug will happen. The
KASAN report triggered by POC is shown below:

The default device address apparently comes from the NVM configuration
file and can differ quite a bit between controllers.
Store the default address when parsing the configuration file and use it
to determine whether the controller has been provisioned with an
address.
This makes sure that devices without a unique address start as
unconfigured unless a valid address has been provided in the devicetree.

The NVM configuration files used by WCN3988 and WCN3990/1/8 have two
sets of configuration tags that are enclosed by a type-length header of
type four which the current parser fails to account for.
Instead the driver happily parses random data as if it were valid tags,
something which can lead to the configuration data being corrupted if it
ever encounters the words 0x0011 or 0x001b.
As is clear from commit b63882549b2b ("Bluetooth: btqca: Fix the NVM
baudrate tag offcet for wcn3991") the intention has always been to
process the configuration data also for WCN3991 and WCN3998 which
encodes the baud rate at a different offset.
Fix the parser so that it can handle the WCN3xxx configuration files,
which has an enclosing type-length header of type four and two sets of
TLV tags enclosed by a type-length header of type two and three,
respectively.
Note that only the first set, which contains the tags the driver is
currently looking for, will be parsed for now.
With the parser fixed, the software in-band sleep bit will now be set
for WCN3991 and WCN3998 (as it is for later controllers) and the default
baud rate 3200000 may be updated by the driver also for WCN3xxx
controllers.
Notably the deep-sleep feature bit is already set by default in all
configuration files in linux-firmware.

Extend a critical section to prevent chan from early freeing.
Also make the l2cap_connect() return type void. Nothing is using the
returned value but it is ugly to return a potentially freed pointer.
Making it void will help with backports because earlier kernels did use
the return value. Now the compile will break for kernels where this
patch is not a complete fix.

Qualcomm Bluetooth controllers may not have been provisioned with a
valid device address and instead end up using the default address
00:00:00:00:5a:ad.
This address is now used to determine if a controller has a valid
address or if one needs to be provided through devicetree or by user
space before the controller can be used.
It turns out that the WCN3991 controllers used in Chromium Trogdor
machines use a different default address, 39:98:00:00:5a:ad, which also
needs to be marked as invalid so that the correct address is fetched
from the devicetree.
Qualcomm has unfortunately not yet provided any answers as to whether
the 39:98 encodes a hardware id and if there are other variants of the
default address that needs to be handled by the driver.
For now, add the Trogdor WCN3991 default address to the device address
check to avoid having these controllers start with the default address
instead of their assigned addresses.

When the sco connection is established and then, the sco socket
is releasing, timeout_work will be scheduled to judge whether
the sco disconnection is timeout. The sock will be deallocated
later, but it is dereferenced again in sco_sock_timeout. As a
result, the use-after-free bugs will happen. The root cause is
shown below:
Cleanup Thread | Worker Thread
sco_sock_release |
sco_sock_close |
__sco_sock_close |
sco_sock_set_timer |
schedule_delayed_work |
sco_sock_kill | (wait a time)

whether the conn->hcon is null. Because the conn->hcon will be set to null,
when the sock is releasing.

Previously we claimed "pcie_aspm=off" meant that ASPM would be disabled,
which is wrong.
Correct this to say that with "pcie_aspm=off", Linux doesn't touch any ASPM
configuration at all. ASPM may have been enabled by firmware, and that
will be left unchanged. See "aspm_support_enabled".

Fix the cmdline parsing of the "blkdevparts=" parameter using strsep(),
which makes the code simpler.
Before commit 146afeb235cc ("block: use strscpy() to instead of
strncpy()"), we used a strncpy() to copy a block device name and partition
names. The commit simply replaced a strncpy() and NULL termination with
a strscpy(). It did not update calculations of length passed to strscpy().
While the length passed to strncpy() is just a length of valid characters
without NULL termination ('\0'), strscpy() takes it as a length of the
destination buffer, including a NULL termination.
Since the source buffer is not necessarily NULL terminated, the current
code copies "length - 1" characters and puts a NULL character in the
destination buffer. It replaces the last character with NULL and breaks
the parsing.
As an example, that buffer will be passed to parse_parts() and breaks
parsing sub-partitions due to the missing ')' at the end, like the
following.
example (Check Point V-80 & OpenWrt):

By the way, strscpy() takes a length of destination buffer and it is
often confusing when copying characters with a specified length. Using
strsep() helps to separate the string by the specified character. Then,
we can use strscpy() naturally with the size of the destination buffer.
Separating the string on the fly is also useful to omit the redundant
string copy, reducing memory usage and improve the code readability.

blkdev_iomap_begin rounds down the offset to the logical block size

While this doesn't provide much value as is, having the devices as
disabled in the device tree will allow developers to see that the rk3588
actually has IOMMUs on the SoC.

The 4xxx driver can probe 4xxx and 402xx devices. However, the driver
only specifies the firmware images required for 4xxx.
This might result in external tools missing these binaries, if required,
in the initramfs.
Specify the firmware image used by 402xx with the MODULE_FIRMWARE()
macros in the 4xxx driver.

When no mode is set, the utility pin appears to be grounded. No signal
is getting through.
This is problematic because ARC and eARC use this line and may do so even
if no display mode is set.
This change enable the bandgap setting on g12 chip, which fix the problem
with the utility pin. This is done by restoring init values on PHY init and
disable.

The phy is not in a useful state right after init. It will become useful,
including for auxiliary function such as CEC or ARC, after the first mode
is set. This is a problem on systems where the display is using another
interface like DSI or CVBS.
This change refactor the init and mode change callback to power up the PHY
on init and leave only what is necessary for mode changes in the related
function. This is enough to fix CEC operation when HDMI display is not
enabled.

The pinctrl instances hsi1, gsactrl, and gsacore need a clock for
register access to work.
Since we haven't implemented the relevant CMUs for the clocks required
by these instances just add empty clocks for now so as to make the DT
pass the validation checks.
Once the clocks are implmented in the gs101 clock driver, these should
be updated then.
