On many Qualcomm platforms the PMIC RTC control and time registers are
read-only so that the RTC time can not be updated. Instead an offset
needs be stored in some machine-specific non-volatile memory, which a
driver can take into account.
On platforms where the offset is stored in a Qualcomm specific UEFI
variable the variables are also accessed in a non-standard way, which
means that the OS cannot assume that the variable service is available
by the time the RTC driver probes.
Use the new 'qcom,uefi-rtc-info' property to indicate that the offset is
stored in a UEFI variable so that the OS can determine whether to wait
for it to become available.

Creating a child cpuset where cpuset.mems is never set leads to a div/0
when a VMA mempolicy with MPOL_F_RELATIVE_NODES rebinds in response to a
CPU hotplug event.
Reproduction steps:
1) Create a cgroup w/ cpuset controls (do not set cpuset.mems)
2) Move the task into the child cpuset
3) Create a VMA mempolicy for that task with MPOL_F_RELATIVE_NODES
4) unplug and hotplug a cpu
echo 0 > /sys/devices/system/cpu/cpu1/online
echo 1 > /sys/devices/system/cpu/cpu1/online
5) mempolicy rebind does a div/0 in mpol_relative_nodemask on the
call to __nodes_fold()
The cpuset code passes (cs->mems_allowed) which is not guaranteed to have
nodes to the rebind routine. Use cs->effective_mems instead, which is
guaranteed to have a non-empty nodemask once we reach that code path.

When RB_FORCE_8BYTE_ALIGNMENT is true, rb_calculate_event_length()
reserves the space of event->array[0] for placing the data length and
rb_update_event() stores the data length in event->array[0]
accordingly. As a result the whole event length will add extra 4 bytes
for sizeof(event.array[0]) unconditionally.
But ring_buffer_event_length() only subtracts the
sizeof(event->array[0]) for events larger than RB_MAX_SMALL_DATA +
sizeof(event->array[0]). As a result, small events on architectures
with RB_FORCE_8BYTE_ALIGNMENT=true report a data length that is 4
bytes larger than expected.
To fix it, add the RB_FORCE_8BYTE_ALIGNMENT as a condition to subtract
the size of that length field whenever RB_FORCE_8BYTE_ALIGNMENT is
true.
This issue is observed in a riscv64 kernel with
CONFIG_HAVE_64BIT_ALIGNED_ACCESS set to y, when we run ftrace selftest
trace_marker_raw.tc, we get the weird log: for cases where the id is
1..100, the number of data field is 8*N, but once id exceeds 100, the
number of data field becomes 8*N+4:
# 1 buf: 58 00 00 00 80 5e d1 63 (number of data field is 8*1)
...
# a buf: 58 ... (number of data field is 8*2)
...
# 64 buf: 58 ... (number of data field is 8*13)
# 65 buf: 58 ... (number of data field is 8*13+4)
After applying this change, the number of data field keeps being 8*N+4
consistently.

pnp_add_card() ignores __pnp_add_device() failures. If device_register()
fails there, the device is removed from the global and protocol lists, but
remains on the card list and its device reference is not dropped.
Remove the failed device from the card list and call put_device() before
continuing with the remaining card devices.

numa_add_memblk() now sets the node in numa_nodes_parsed itself, so the
caller's own node_set() is redundant. Remove it.
No functional change.

Add DTC_FLAGS -@ for all H2+ pi-class devices to enable device-tree
overlay support. This follows the same approach used for H3 pi boards
in commit 0801a3a9f3 ("arm: dts: Enable
device-tree overlay support for sun8i-h3 pi devices").
The -@ flag populates the __symbols__ node in the DTB which is required
for applying device-tree overlays from the bootloader or firmware.
Boards affected:
- sun8i-h2-plus-bananapi-m2-zero
- sun8i-h2-plus-libretech-all-h3-cc
- sun8i-h2-plus-orangepi-r1

following interfaces:
- 10/100 Mbps Ethernet
- USB Type-C OTG using a TUSB320 (usb0)
- USB Type-C Console Port using a CH340 (uart3)
- USB Type-A Host with internal CH334 USB-Hub (usb1)
- MicroSD Slot with Card-Detect (mmc0)
- WiFi/Bluetooth using the modules built-in ESP32
- SmartSlot serial interface (uart4)
- DS3232 RTC with CR1220 Battery Backup
- Extension connector providing SPI,I2C,USB,CAN,UART for future use.

Some __create_synth_event() error paths run after parse_synth_field()
succeeds but before the field is stored in fields[]. The common cleanup
then misses the field. Free it before freeing argv.

and dual power role capabilities. Add the Type-C device node and
enable the corresponding USB controller and phy node.

Switch to use flattened model for USB3 controller. To enable USB
controller with restricted DMA access range to work correctly, add a
simple-bus to constrain the dma address.
Note:
This changes the USB controller compatible string from "fsl,imx95-dwc3"
to "nxp,imx95-dwc3". This requires a kernel with CONFIG_USB_DWC3_IMX
enabled; otherwise, the new DTB will not be compatible with older one.
As i.MX95 is a new SoC and is still under development, it's acceptable
at development early phase.
