Since commit 57eb14779dfd ("interconnect: qcom: icc-rpmh: Support child
NoC device probe") the icc-rpmh driver supports initializing child NoCs,
but those child NoCs also need to be able to get the parent's regmap in
order to enable QoS.
Change the driver to support that and support programming QoS register.

Currently most of Qualcomm interconnect drivers use static IDs, which
poses a threat of possible conflicts with other drivers. Rework RPMh
interconnect drivers to use dynamic IDs and drop static IDs

This enables QoS configuration for QNOC type device which can be found
on SA8775P platform. It enables QoS configuration for master ports with
predefined priority and urgency forwarding. This helps in prioritizing
the traffic originating from different interconnect masters at NOC.
The system may function normally without this feature. However, enabling
QoS helps optimize latency and bandwidth across subsystems like CPU, GPU,
and multimedia engines, which becomes important in high-throughput
scenarios. This is a feature aimed at performance enhancement to improve
system performance under concurrent workloads.

Drop the QPIC interconnect and BCM nodes for the SDX75 SoC. The reason
is that this QPIC BCM resource is already defined as a RPMh clock in
clk-rpmh driver as like other SDX SoCs. So it is wrong to describe the
same resource in two different providers.
Also, without this series, the NAND driver fails to probe on SDX75 as
the interconnect sync state disables the QPIC nodes as there were no
clients voting for this ICC resource. However, the NAND driver had already
voted for this BCM resource through the clk-rpmh driver. Since both votes
come from Linux, RPMh was unable to distinguish between these two and ends
up disabling the resource during sync state.

The icc_commit_set() function, used by the debugfs interface, checks
the validity of the global cur_path pointer using IS_ERR_OR_NULL().
However, in the specific case where cur_path is NULL, while
IS_ERR_OR_NULL(NULL) correctly evaluates to true, the subsequent call
to PTR_ERR(NULL) returns 0.
This causes the function to return a success code (0) instead of an
error, misleading the user into believing their bandwidth request was
successfully committed when, in fact, no operation was performed.
Fix this by adding an explicit check to return -EINVAL if cur_path is
NULL. This prevents silent failures and ensures that an invalid
operational sequence is immediately and clearly reported as an error.

As like other SDX SoCs, SDX75 SoC's QPIC BCM resource was modeled as a
RPMh clock in clk-rpmh driver. However, for SDX75, this resource was also
described as an interconnect and BCM node mistakenly. It is incorrect to
describe the same resource in two different providers, as it will lead to
votes from clients overriding each other.
Hence, drop the QPIC interconnect and BCM nodes and let the clients use
clk-rpmh driver to vote for this resource.
Without this change, the NAND driver fails to probe on SDX75, as the
interconnect sync state disables the QPIC nodes as there were no clients
voting for this ICC resource. However, the NAND driver had already voted
for this BCM resource through the clk-rpmh driver. Since both votes come
from Linux, RPMh was unable to distinguish between these two and ends up
disabling the QPIC resource during sync state.

Pull SCSI fixes from James Bottomley:
"Fixes only in drivers (ufs, mvsas, qla2xxx, target) that came in just
before or during the merge window.
The most important one is the qla2xxx which reverts a conversion to
fix flexible array member warnings, that went up in this merge window
but which turned out on further testing to be causing data corruption"

Pull more x86 updates from Borislav Petkov:
- Remove a bunch of asm implementing condition flags testing in KVM's
emulator in favor of int3_emulate_jcc() which is written in C
- Replace KVM fastops with C-based stubs which avoids problems with the
fastop infra related to latter not adhering to the C ABI due to their
special calling convention and, more importantly, bypassing compiler
control-flow integrity checking because they're written in asm
- Remove wrongly used static branches and other ugliness accumulated
over time in hyperv's hypercall implementation with a proper static
function call to the correct hypervisor call variant
- Add some fixes and modifications to allow running FRED-enabled
kernels in KVM even on non-FRED hardware
- Add kCFI improvements like validating indirect calls and prepare for
enabling kCFI with GCC. Add cmdline params documentation and other
code cleanups
- Use the single-byte 0xd6 insn as the official #UD single-byte
undefined opcode instruction as agreed upon by both x86 vendors
- Other smaller cleanups and touchups all over the place
* tag 'x86_core_for_v6.18_rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: (24 commits)
