2668e3ae2e SCSI fixes on 20240418
Two minor fixes: one in the core to improve the handling of warnings
 and unconditionally clear the command flags when ending a request and
 the other to add missing table values needed for bandwidth scaling in
 qualcomm ufs.

8d7077f53e drm/i915/display: add generic to_intel_display() macro
Convert various pointers to struct intel_display * using _Generic().

Add some macro magic to make adding new conversions easier, and somewhat
abstract the need to cast each generic association. The cast is required
because all associations needs to compile, regardless of the type and
the generic selection.

The use of *p in the generic selection assignment expression removes the
need to add separate associations for const pointers.

Note: This intentionally does *not* cover struct drm_i915_private or
struct xe_device. They are not to be used in the long run, so avoid
using this macro for them.

02c19d84c7 firmware: arm_ffa: Add support for FFA_MSG_SEND2
The FFA_MSG_SEND2 can be  used to transmit a partition message from
the Tx buffer of the sender(the driver in this case) endpoint to the Rx
buffer of the receiver endpoint.

An invocation of the FFA_MSG_SEND2 transfers the ownership of the Tx
buffer to the receiver endpoint(or any intermediate consumer). Completion
of an FFA_MSG_SEND2 invocation transfers the ownership of the buffer
back to the sender endpoint.

The framework defines the FFA_MSG_SEND2 interface to transmit a partition
message from the Tx buffer of the sender to the Rx buffer of a receiver
and inform the scheduler that the receiver must be run.

9259a47216 string_kunit: Add test cases for str*cmp functions
Currently, str*cmp functions (strcmp, strncmp, strcasecmp and
strncasecmp) are not covered with tests. Extend the `string_kunit.c`
test by adding the test cases for them.

This patch adds 8 more test cases:

1) strcmp test
2) strcmp test on long strings (2048 chars)
3) strncmp test
4) strncmp test on long strings (2048 chars)
5) strcasecmp test
6) strcasecmp test on long strings
7) strncasecmp test
8) strncasecmp test on long strings

These test cases aim at covering as many edge cases as possible,
including the tests on empty strings, situations when the different
symbol is placed at the end of one of the strings, etc.

34e526cb7d arm64/head: Disable MMU at EL2 before clearing HCR_EL2.E2H
Even though the boot protocol stipulates otherwise, an exception has
been made for the EFI stub, and entering the core kernel with the MMU
enabled is permitted. This allows a substantial amount of cache
maintenance to be elided, wich is significant when fast boot times are
critical (e.g., for booting micro-VMs)

Once the initial ID map has been populated, the MMU is disabled as part
of the logic sequence that puts all system registers into a known state.
Any code that needs to execute within the window where the MMU is off is
cleaned to the PoC explicitly, which includes all of HYP text when
entering at EL2.

However, the current sequence of initializing the EL2 system registers
is not safe: HCR_EL2 is set to its nVHE initial state before SCTLR_EL2
is reprogrammed, and this means that a VHE-to-nVHE switch may occur
while the MMU is enabled. This switch causes some system registers as
well as page table descriptors to be interpreted in a different way,
potentially resulting in spurious exceptions relating to MMU
translation.

So disable the MMU explicitly first when entering in EL2 with the MMU
and caches enabled.

56f78615bc net: usb: ax88179_178a: avoid writing the mac address before first reading
After the commit d2689b6a86 ("net: usb: ax88179_178a: avoid two
consecutive device resets"), reset operation, in which the default mac
address from the device is read, is not executed from bind operation and
the random address, that is pregenerated just in case, is direclty written
the first time in the device, so the default one from the device is not
even read. This writing is not dangerous because is volatile and the
default mac address is not missed.

In order to avoid this and keep the simplification to have only one
reset and reduce the delays, restore the reset from bind operation and
remove the reset that is commanded from open operation. The behavior is
the same but everything is ready for usbnet_probe.

Tested with ASIX AX88179 USB Gigabit Ethernet devices.
Restore the old behavior for the rest of possible devices because I don't
have the hardware to test.

Pull random number generator fixes from Jason Donenfeld:

 - The input subsystem contributes entropy in some places where a
   spinlock is held, but the entropy accounting code only handled
   callers being in an interrupt or non-atomic process context, but not
   atomic process context. We fix this by removing an optimization and
   just calling queue_work() unconditionally.

 - Greg accidently sent up a patch not intended for his tree and that
   had been nack'd, so that's now reverted.

fe1c6c7acc btrfs: fix wrong block_start calculation for btrfs_drop_extent_map_range()
[BUG]
During my extent_map cleanup/refactor, with extra sanity checks,
extent-map-tests::test_case_7() would not pass the checks.

The problem is, after btrfs_drop_extent_map_range(), the resulted
extent_map has a @block_start way too large.
Meanwhile my btrfs_file_extent_item based members are returning a
correct @disk_bytenr/@offset combination.

The extent map layout looks like this:

     0        16K    32K       48K
     | PINNED |      | Regular |

The regular em at [32K, 48K) also has 32K @block_start.

Then drop range [0, 36K), which should shrink the regular one to be
[36K, 48K).
However the @block_start is incorrect, we expect 32K + 4K, but got 52K.

[CAUSE]
Inside btrfs_drop_extent_map_range() function, if we hit an extent_map
that covers the target range but is still beyond it, we need to split
that extent map into half:

	|<-- drop range -->|
		 |<----- existing extent_map --->|

And if the extent map is not compressed, we need to forward
extent_map::block_start by the difference between the end of drop range
and the extent map start.

However in that particular case, the difference is calculated using
(start + len - em->start).

The problem is @start can be modified if the drop range covers any
pinned extent.

This leads to wrong calculation, and would be caught by my later
extent_map sanity checks, which checks the em::block_start against
btrfs_file_extent_item::disk_bytenr + btrfs_file_extent_item::offset.

This is a regression caused by commit c962098ca4 ("btrfs: fix
incorrect splitting in btrfs_drop_extent_map_range"), which removed the
@len update for pinned extents.

[FIX]
Fix it by avoiding using @start completely, and use @end - em->start
instead, which @end is exclusive bytenr number.

And update the test case to verify the @block_start to prevent such
problem from happening.

Thankfully this is not going to lead to any data corruption, as IO path
does not utilize btrfs_drop_extent_map_range() with @skip_pinned set.

So this fix is only here for the sake of consistency/correctness.

Fix this by using kvzalloc() which zeroes out the memory on allocation.

752863bdda block: propagate partition scanning errors to the BLKRRPART ioctl
Commit 4601b4b130 ("block: reopen the device in blkdev_reread_part")
lost the propagation of I/O errors from the low-level read of the
partition table to the user space caller of the BLKRRPART.

Apparently some user space relies on, so restore the propagation.  This
isn't exactly pretty as other block device open calls explicitly do not
are about these errors, so add a new BLK_OPEN_STRICT_SCAN to opt into
the error propagation.

9543f6e266 x86/cpufeatures: Fix dependencies for GFNI, VAES, and VPCLMULQDQ
Fix cpuid_deps[] to list the correct dependencies for GFNI, VAES, and
VPCLMULQDQ.  These features don't depend on AVX512, and there exist CPUs
that support these features but not AVX512.  GFNI actually doesn't even
depend on AVX.

This prevents GFNI from being unnecessarily disabled if AVX is disabled
to mitigate the GDS vulnerability.

This also prevents all three features from being unnecessarily disabled
if AVX512VL (or its dependency AVX512F) were to be disabled, but it
looks like there isn't any case where this happens anyway.

are found in the kernel log:

event mgmt rx skb         pK-error len 209 ftype 00 stype 50

The "pK-error" comes from using %pK to display an skb address in an
interrupt context.

Per the guidance in the current "printk-formats" documentation, %pK
"is only intended when producing content of a file read by userspace
from e.g. procfs or sysfs, not for dmesg."

So replace %pK with %p in all of the ath12k_dbg() format strings.

42a2f6664e staging: vc04_services: Move global g_state to vchiq_state
The patch intended to drop the g_state pointer.
g_state is supposed to be a central place to track the state
via vchiq_state. This is now moved to be contained in the
struct vchiq_drv_mgmt. As a result vchiq_get_state() is also removed.

In order to have access to vchiq_drv_mgmt, vchiq_initialise()
and vchiq_mmal_init() are modified to receive a struct device pointer
as one of their function parameter

The vchiq_state pointer is now passed directly to
vchiq_dump_platform_instances() to get access to the state instead
getting it via vchiq_get_state().

For the char device, struct miscdevice is retrieved by struct file's
private data in vchiq_open and struct vchiq_drv_mgmt is retrieved
thereafter.

Removal of global variable members is now addressed hence, drop
the corresponding item from the TODO list.

7f56c601ca staging: vc04_services: vchiq_mmal: Rename service_callback()
Rename the service_callback static function to mmal_service_callback()
since the function signature conflicts with:

extern int
service_callback(struct vchiq_instance *vchiq_instance, enum vchiq_reason reason,
                 struct vchiq_header *header, unsigned int handle, void *bulk_userdata);

in vc04_services/interface/vchiq_arm/vchiq_arm.h

In a subsequent patch, we will include vchiq_arm.h header to
mmal-vchiq.c, which will then complain of this conflict. Hence,
this patch is meant to handle the conflict beforehand.

f875976ecf staging: vc04_services: Drop vchiq_connected.[ch] files
The vchiq_connected.[ch] just implements two function:

- vchiq_add_connected_callback()
- vchiq_call_connected_callbacks()

for the deferred vchiq callbacks. Those can easily live in
vchiq_arm.[ch], hence move them. This allows making the
vchiq_call_connected_callbacks() function static.

The move doesn't copy over MAX_CALLBACKS because it is the same as
VCHIQ_DRV_MAX_CALLBACKS. Hence, it now being used in
vchiq_add_connected_callback().

No functional changes intended in this patch.
