An extra blank line gets printed after printing firmware version
because the build date is null terminated. Remove the "\n" from
dev_info() calls to print firmware version and build date to fix
the problem.

This reverts commit f804a5895ebad2b2d4fb8a3688d2115926e993d5.
This change introduced the following panic, and mt792x_load_firmware()
fails. wifi is dead on systems with mt792x wireless.

A value of 0 for addr indicates that the IEB_LBCR register does not
need to be configured, as its default value is 0. However, the driver
will print an error log if addr is 0, so this issue needs to be fixed.

macb_open()
In the non-RT kernel, local_bh_disable() merely disables preemption,
whereas it maps to an actual spin lock in the RT kernel. Consequently,
when attempting to refill RX buffers via netdev_alloc_skb() in
macb_mac_link_up(), a deadlock scenario arises as follows:

Notably, invoking the mog_init_rings() callback upon link establishment
is unnecessary. Instead, we can exclusively call mog_init_rings() within
the ndo_open() callback. This adjustment resolves the deadlock issue.
Furthermore, since MACB_CAPS_MACB_IS_EMAC cases do not use mog_init_rings()
when opening the network interface via at91ether_open(), moving
mog_init_rings() to macb_open() also eliminates the MACB_CAPS_MACB_IS_EMAC
check.

syzbot reported a crash [1] in dql_completed() after recent usbnet
BQL adoption.
The reason for the crash is that netdev_reset_queue() is called too soon.
It should be called after cancel_work_sync(&dev->bh_work) to make
sure no more TX completion can happen.

Use the `IRQF_NO_AUTOEN` flag when requesting interrupts to prevent auto
enablement and explicitly enable the interrupt in NAPI initialization
path (and disable it during NAPI teardown).
This ensures that interrupt lifecycle is strictly coupled with
readiness of NAPI context.

For XDP_TX action, the xdp_buff is converted to xdp_frame by
xdp_convert_buff_to_frame(). The memory type of the resulting xdp_frame
depends on the memory type of the xdp_buff. For page pool based xdp_buff
it produces xdp_frame with memory type MEM_TYPE_PAGE_POOL. For zero copy
XSK pool based xdp_buff it produces xdp_frame with memory type
MEM_TYPE_PAGE_ORDER0. However, stmmac_xdp_xmit_back() does not check the
memory type and always uses the page pool type, this leads to invalid
mappings and causes the crash. Therefore, check the xdp_buff memory type
in stmmac_xdp_xmit_back() to fix this issue.

The PMT feature probe creates a child device with device_create().
If device creation fail, the code pass priv->dev (which is an ERR_PTR)
to dev_err_probe(), which is not a valid device pointer.

device (&auxdev->dev) and update the error message to reference the
parent device name. It ensure correct error reporting and avoid

The hp_populate_*_elements_from_package() functions in the hp-bioscfg
driver contain out-of-bounds array access vulnerabilities.
These functions parse ACPI packages into internal data structures using
a for loop with index variable 'elem' that iterates through
enum_obj/integer_obj/order_obj/password_obj/string_obj arrays.
When processing multi-element fields like PREREQUISITES and
ENUM_POSSIBLE_VALUES, these functions read multiple consecutive array
elements using expressions like 'enum_obj[elem + reqs]' and
'enum_obj[elem + pos_values]' within nested loops.
The bug is that the bounds check only validated elem, but did not consider
the additional offset when accessing elem + reqs or elem + pos_values.
The fix changes the bounds check to validate the actual accessed index.

A user reported that reading the charge threshold on his device
results in very strange values (like 78497792) being returned.
The reason for this seems to be the fact that the driver casts
the int pointer to an u8 pointer, leaving the last 3 bytes of
the destination uninitialized. Fix this by using a temporary
variable instead.

When mana_serv_reset() encounters -ETIMEDOUT or -EPROTO from
mana_gd_resume(), it performs a PCI rescan via mana_serv_rescan().
mana_serv_rescan() calls pci_stop_and_remove_bus_device(), which can
invoke the driver's remove path and free the gdma_context associated
with the device. After returning, mana_serv_reset() currently jumps to
the out label and attempts to clear gc->in_service, dereferencing a
freed gdma_context.

Linux 6.19-rc2 (9448598b22c5 ("Linux 6.19-rc2")) is crashing with a NULL
pointer dereference on arm64 hosts:
Unable to handle kernel NULL pointer dereference at virtual address 00000000000000c8

I've bissected the problem to commit a5baf582f4c0 ("arm64/efi: Call EFI
runtime services without disabling preemption").
>From my analyzes, the crash occurs because efi_mm lacks a user_ns field
initialization. This was previously harmless, but commit a5baf582f4c0
("arm64/efi: Call EFI runtime services without disabling preemption")
changed the EFI runtime call path to use kthread_use_mm(&efi_mm), which
temporarily adopts efi_mm as the current mm for the calling kthread.
When a thread has an active mm, LSM hooks like cap_capable() expect
mm->user_ns to be valid for credential checks. With efi_mm.user_ns being
NULL, capability checks during possible /proc access dereference the
NULL pointer and crash.
Fix by initializing efi_mm.user_ns to &init_user_ns.

The efi_edid_discovered_protocol and efi_edid_active_protocol have mixed
mode fields. So all their attributes should be accessed through
the efi_table_attr() helper.
Doing so fixes the upper 32 bits of the 64 bit gop_edid pointer getting
set to random values (followed by a crash at boot) when booting a x86_64
kernel on a machine with 32 bit UEFI like the Asus T100TA.

The refill_buf function uses snprintf to append to a fixed-size buffer.
snprintf returns the length that would have been written, which can
exceed the remaining buffer size. If this happens, ptr advances beyond
the buffer and rem becomes negative. In the 2nd iteration, rem is
treated as a large unsigned integer, causing snprintf to write oob.
While this behavior is technically mitigated by num_perfcntrs being
locked at 5, it's still unsafe if num_perfcntrs were ever to change/a
second source was added.

vhost_vsock_get() uses hash_for_each_possible_rcu() to find the
`vhost_vsock` associated with the `guest_cid`. hash_for_each_possible_rcu()
should only be called within an RCU read section, as mentioned in the
following comment in include/linux/rculist.h:
/**
* hlist_for_each_entry_rcu - iterate over rcu list of given type
* @pos: the type * to use as a loop cursor.
* @head: the head for your list.
* @member: the name of the hlist_node within the struct.
* @cond: optional lockdep expression if called from non-RCU protection.
*
* This list-traversal primitive may safely run concurrently with
* the _rcu list-mutation primitives such as hlist_add_head_rcu()
* as long as the traversal is guarded by rcu_read_lock().
*/
Currently, all calls to vhost_vsock_get() are between rcu_read_lock()
and rcu_read_unlock() except for calls in vhost_vsock_set_cid() and
vhost_vsock_reset_orphans(). In both cases, the current code is safe,
but we can make improvements to make it more robust.
About vhost_vsock_set_cid(), when building the kernel with
CONFIG_PROVE_RCU_LIST enabled, we get the following RCU warning when the
user space issues `ioctl(dev, VHOST_VSOCK_SET_GUEST_CID, ...)` :

This is not a real problem, because the vhost_vsock_get() caller, i.e.
vhost_vsock_set_cid(), holds the `vhost_vsock_mutex` used by the hash
table writers. Anyway, to prevent that warning, add lockdep_is_held()
condition to hash_for_each_possible_rcu() to verify that either the
caller is in an RCU read section or `vhost_vsock_mutex` is held when
CONFIG_PROVE_RCU_LIST is enabled; and also clarify the comment for
vhost_vsock_get() to better describe the locking requirements and the
scope of the returned pointer validity.
About vhost_vsock_reset_orphans(), currently this function is only
called via vsock_for_each_connected_socket(), which holds the
`vsock_table_lock` spinlock (which is also an RCU read-side critical
section). However, add an explicit RCU read lock there to make the code
more robust and explicit about the RCU requirements, and to prevent
issues if the calling context changes in the future or if
vhost_vsock_reset_orphans() is called from other contexts.
