The downstream TLMM binding covers a group of TLMM-related hardware
blocks, but the upstream binding only captures the particular block
related to controlling the TLMM pins from an OS. In the translation of
the driver from downstream, the offset of 0x100000 was lost for the UFS
and SDC pingroups.

It has been observed that dual edge triggered wakeirq GPIOs on SDM845
doesn't trigger interrupts on the falling edge.
Enabling wakeirq_dual_edge_errata for SDM845 indicates that the PDC in
SDM845 suffers from the same problem described, and worked around, by
Doug in 'c3c0c2e18d94 ("pinctrl: qcom: Handle broken/missing PDC dual
edge IRQs on sc7180")', so enable the workaround for SDM845 as well.
The specific problem seen without this is that gpio-keys does not detect
the falling edge of the LID gpio on the Lenovo Yoga C630 and as such
consistently reports the LID as closed.

On some Lenovo AMD Gen2 platforms the IRQ for the SCI and pinctrl drivers
are shared. Due to how the s2idle loop handling works, this case needs
an extra explicit check whether the interrupt was caused by SCI or by
the GPIO controller.
To fix this rework the existing IRQ handler function to function as a
checker and an IRQ handler depending on the calling arguments.

While issuing VF Reset from the guest OS, the VF driver prints
logs about critical / Overflow error detection. This is not an
actual error since the VF_MBX_ARQLEN register is set to all FF's
for a short period of time and the VF would catch the bits set if
it was reading the register during that spike of time.
This patch introduces an additional check to ignore this condition
since the VF is in reset.

In iavf_config_clsflower, the filter structure could be accidentally
released at the end, if iavf_parse_cls_flower or iavf_handle_tclass ever
return a non-zero but positive value.
In this case, the function continues through to the end, and will call
kfree() on the filter structure even though it has been added to the
linked list.
This can actually happen because iavf_parse_cls_flower will return
a positive IAVF_ERR_CONFIG value instead of the traditional negative
error codes.
Fix this by ensuring that the kfree() check and error checks are
similar. Use the more idiomatic "if (err)" to catch all non-zero error
codes.

Currently when removing an ipmi_user the removal is deferred as a work on
the system's workqueue. Although this guarantees the free operation will
occur in non atomic context, it can race with the ipmi_msghandler module
removal (see [1]) . In case a remove_user work is scheduled for removal
and shortly after ipmi_msghandler module is removed we can end up in a
situation where the module is removed fist and when the work is executed
the system crashes with :
BUG: unable to handle page fault for address: ffffffffc05c3450
PF: supervisor instruction fetch in kernel mode
PF: error_code(0x0010) - not-present page
because the pages of the module are gone. In cleanup_ipmi() there is no
easy way to detect if there are any pending works to flush them before
removing the module. This patch creates a separate workqueue and schedules
the remove_work works on it. When removing the module the workqueue is
drained when destroyed to avoid the race.

This bug report shows up when running our research tools. The
reports is SOOB read, but it seems SOOB write is also possible
a few lines below.
In details, fw.len and sw.len are inputs coming from io. A len
over the size of self->rpc triggers SOOB. The patch fixes the
bugs by adding sanity checks.
The bugs are triggerable with compromised/malfunctioning devices.
They are potentially exploitable given they first leak up to
0xffff bytes and able to overwrite the region later.
The patch is tested with QEMU emulater.
This is NOT tested with a real device.
Attached is the log we found by fuzzing.

As stated in the bonding doc, trans_start must be set manually for drivers
using NETIF_F_LLTX:
Drivers that use NETIF_F_LLTX flag must also update
netdev_queue->trans_start. If they do not, then the ARP monitor will
immediately fail any slaves using that driver, and those slaves will stay
down.

Baihua reported an error when boot an ARM64 guest with PAGE_SIZE=64k and
BALLOON is enabled:
hv_vmbus: registering driver hv_balloon
hv_vmbus: probe failed for device 1eccfd72-4b41-45ef-b73a-4a6e44c12924 (-22)
The cause of this is that the ringbuffer size for hv_balloon is not
adjusted with VMBUS_RING_SIZE(), which makes the size not large enough
for ringbuffers on guest with PAGE_SIZE=64k. Therefore use
VMBUS_RING_SIZE() to calculate the ringbuffer size. Note that the old
size (20 * 1024) counts a 4k header in the total size, while
VMBUS_RING_SIZE() expects the parameter as the payload size, so use
16 * 1024.

When PHY_SUN6I_MIPI_DPHY is selected, and RESET_CONTROLLER
is not selected, Kbuild gives the following warning:
WARNING: unmet direct dependencies detected for PHY_SUN6I_MIPI_DPHY
Depends on [n]: (ARCH_SUNXI [=n] || COMPILE_TEST [=y]) && HAS_IOMEM [=y] && COMMON_CLK [=y] && RESET_CONTROLLER [=n]
Selected by [y]:

This is because DRM_SUN6I_DSI selects PHY_SUN6I_MIPI_DPHY
without selecting or depending on RESET_CONTROLLER, despite
PHY_SUN6I_MIPI_DPHY depending on RESET_CONTROLLER.
These unmet dependency bugs were detected by Kismet,

is not the appropriate solution.

Use the GFP_ATOMIC flag of kzalloc() with two memory allocation in
report_del_sta_event(). This function is called while holding spinlocks,
therefore it is not allowed to sleep. With the GFP_ATOMIC type flag, the
allocation is high priority and must not sleep.
This issue is detected by Smatch which emits the following warning:
"drivers/staging/r8188eu/core/rtw_mlme_ext.c:6848 report_del_sta_event()
warn: sleeping in atomic context".
After the change, the post-commit hook output the following message:
"CHECK: Prefer kzalloc(sizeof(*pcmd_obj)...) over
kzalloc(sizeof(struct cmd_obj)...)".
According to the above "CHECK", use the preferred style in the first
kzalloc().

In commit 221abd4d478a ("staging: r8188eu: Remove no more necessary definitions
and code"), two entries were removed from RTW_ChannelPlanMap[], but not replaced
with zeros. The position within this table is important, thus the patch broke
systems operating in regulatory domains osted later than entry 0x13 in the table.
Unfortunately, the FCC entry comes before that point and most testers did not see
this problem.

"A set of fixes for the interrupt subsystem
Core code:
- A regression fix for the Open Firmware interrupt mapping code where
a interrupt controller property in a node caused a map property in
the same node to be ignored.
Interrupt chip drivers:
- Workaround a limitation in SiFive PLIC interrupt chip which
silently ignores an EOI when the interrupt line is masked.
- Provide the missing mask/unmask implementation for the CSKY MP
interrupt controller.
PCI/MSI:
- Prevent a use after free when PCI/MSI interrupts are released by
destroying the sysfs entries before freeing the memory which is
accessed in the sysfs show() function.
- Implement a mask quirk for the Nvidia ION AHCI chip which does not
advertise masking capability despite implementing it. Even worse
the chip comes out of reset with all MSI entries masked, which due
to the missing masking capability never get unmasked.
- Move the check which prevents accessing the MSI[X] masking for XEN
back into the low level accessors. The recent consolidation missed
that these accessors can be invoked from places which do not have
that check which broke XEN. Move them back to he original place
instead of sprinkling tons of these checks all over the code"
