IPQ8074 supports split firmware for q6 and m3 as well.
So add support for loading the m3 firmware before q6.
Now the drivers works fine for both split and unified
firmwares.

Currently, when handling the SPMI summary interrupt, the hw_irq
number is calculated based on SID, Peripheral ID, IRQ index and
APID. This is then passed to irq_find_mapping() to see if a
mapping exists for this hw_irq and if available, invoke the
interrupt handler. Since the IRQ index uses an
clang produces .eh_frame sections when CONFIG_GCOV_KERNEL is enabled,

Modifies CONFIG_DEBUG_INFO_DWARF4 to be a member of a choice which is
the default. Does so in a way that's forward compatible with existing
configs, and makes adding future versions more straightforward.
GCC since ~4.8 has defaulted to this DWARF version implicitly.

The Command Effects Log (CEL) is specified in the CXL 2.0 specification.
The CEL is one of two types of logs, the other being vendor specific.
They are distinguished in hardware/spec via UUID. The CEL is immediately
useful for 2 things:
1. Determine which optional commands are supported by the CXL
The Get Log command returns the actual log entries that are advertised
via the Get Supported Logs command (0400h). CXL device logs are selected
by UUID which is part of the CXL spec. Because the driver tries to
sanitize what is sent to hardware, there becomes a need to restrict the
types of logs
Provide enough functionality to utilize the mailbox of a memory device.
The mailbox is used to interact with the firmware running on the memory
device.
The CXL specification defines separate capabilities for the mailbox and
the memory device. The mailbox interface has a doorbell to indicate

The CXL.mem protocol allows a device to act as a provider of "System
RAM" and/or "Persistent Memory" that is fully coherent as if the memory
was attached to the typical CPU memory controller.
With the CXL-2.0 specification a PCI endpoint can implement a "Type-3"
device
All the necessary bits are initialized in order to find and map the
register space for CXL Memory Devices. This is accomplished by using the
Register Locator DVSEC (CXL 2.0 - 8.1.9.1) to determine which PCI BAR to
use, and how much of an offset from that BAR should be added.
If the memory device

AF_RXRPC sockets use UDP ports in encap mode. This causes socket and dst
from an incoming packet to get stolen and attached to the UDP socket from
whence it is leaked when that socket is closed.
When a network namespace is removed, the wait for dst records to be cleaned
up happens before the

Collect the time when each allocation is freed, to help with memory
analysis with kdump/ramdump.
Having another timestamp when we free the page helps for debugging
page migration issues. For example both alloc and free timestamps
being the same can gave hints that there is an issue with migrating
