Add the qfprom efuse node and describe where the GPU speedbin fuse is
located on Milos.
Note that for SM7635-AB at least, the value is "221", the max frequency
for this is 1050MHz. There's another speedbin out there for 1150MHz but
we do not know the value for it so just document in this commit.
Once the value is discovered we should add the speedbins to the A810
Adreno entry and update devicetree.

Add CoreSight nodes to enable trace paths like TPDM->ETF/STM->ETF.
These devices are part of the AOSS, CDSP, QDSS, PCIe5, TraceNoc and
some small subsystems, such as GCC, IPCC, PMU and so on.
Delete cti_wpss DT node on Mahua since this device will cause NoC issue

Downstream kernels for RB3 Gen2 don't specify the RMTFS address, instead
the kernel is supposed to allocate rmtfs buffers dynamically. The
upstream kernel doesn't support dynamic allocation of RMTFS buffers, so
use the fixed allocation. The RMTFS node (and corresponding interface)
is required for the modem DSP to work (which otherwise would crash).

The LeMans EVK board routes the RX lines of CAN controllers 2, 4, and 6
(part of the RTSS subsystem) through a signal multiplexer controlled by
GPIO 4 of the I2C GPIO expander at address 0x3b. The remaining CAN
controllers, out of 8 total on RTSS, are wired directly to their
transceivers.
The multiplexer select pin defaults low on reset, disconnecting CAN 2,
4, and 6 RX lines from their respective transceivers, which results in
no data being received on these interfaces.
Configure GPIO 4 as output-high to assert the mux select line at boot,
connecting the RX signals of CAN 2, 4, and 6 to their transceivers as
required by the EVK board wiring.

The i2c19 node at 0x88c000 uses GIC SPI 584, but that interrupt
belongs to the neighboring i2c18/spi18 node at 0x888000. The correct
interrupt for i2c19 is GIC SPI 585, as used by its sibling nodes
spi19 and uart19 which share the same register base and clock.

Both GCC [1] and Clang [2] consider the generic version of _THIS_IP_ to
be broken:
#define _THIS_IP_ ({ __label__ __here; __here: (unsigned long)&&__here; })
In particular, the address of a label is only expected to be used with a
computed goto.
While the generic version more or less works today, it is known to be
brittle and may break with current and future optimizations. For
example, Clang -O2 always returns 1 when this function is inlined:
static inline unsigned long get_ip(void)
{ return ({ __label__ __here; __here: (unsigned long)&&__here; }); }
Fix it by overriding _THIS_IP_ in <asm/linkage.h> (which is included by
<linux/instruction_pointer.h>) using an architecture-specific inline asm
version. Additionally, avoiding taking the address of a label prevents
compilers from emitting spurious indirect branch targets (e.g. ENDBR or
BTI) under control-flow integrity schemes.

The eDP PHY nodes on lemans were missing the reference clock voting.
This initially went unnoticed because the clock was implicitly enabled
by the UFS PHY driver, and the eDP PHY happened to rely on that.
After commit 77d2fa54a945 ("scsi: ufs: qcom : Refactor phy_power_on/off
calls"), the UFS driver no longer keeps the reference clock enabled.
As a result, the eDP PHY fails to power on.
To fix this, add eDP reference clock for eDP PHYs on lemans chipset
ensuring reference clock is enabled.

emulation
When KVM_GUESTDBG_USE_HW_BP is enabled, i.e. userspace is usurping the
guest's hardware debug registers, the guest's effective breakpoints are
controlled by userspace rather than by the guest itself. Honor the
KVM_GUESTDBG_USE_HW_BP behavior when handling code #DBs in the emulator so
that userspace (and the guest) gets consistent behavior for code #DBs
regardless of whether an instruction is executed natively or emulated by
KVM.
To aid in userspace debug, don't treat code breakpoints as inhibited if
KVM_GUESTDBG_USE_HW_BP is enabled as accurately emulating x86 architecture
is obviously a non-goal of guest-debug.

Pull networking fixes from Jakub Kicinski:
"Including fixes from Bluetooth, wireless and netfilter.
Craziness continues with no end in sight. Even discounting the driver
revert this is a pretty huge PR for standards of the previous era. I'd
speculate - we haven't seen the worst of it, yet. Good news, I guess,
is that so far we haven't seen many (any?) cases of "AI reported a
bug, we fixed it and a real user regressed".
Current release - fix to a fix:
- Bluetooth: btmtk: accept too short WMT FUNC_CTRL events
- vsock/virtio: relax the recently added memory limit a little
Current release - regressions:
- IB/IPoIB: make sure IB drivers always use async set_rx_mode since
some (mlx5) are now required to use it due to locking changes
Previous releases - regressions:
- udp: fix UDP length on last GSO_PARTIAL segment
- af_unix: fix UAF read of tail->len in unix_stream_data_wait()
- tcp: fix stale per-CPU tcp_tw_isn leak enabling ISN prediction
- mlx5e: fix unlocked writing to ICOSQ, breaking AF_XDP
Previous releases - always broken:
- tap: fix stack info leak in tap_ioctl() SIOCGIFHWADDR
- ipv4: raw: reject IP_HDRINCL packets with ihl < 5
- Bluetooth: a lot of locking and concurrency fixes (as always)
- batman-adv (mesh wireless networking): a lot of random fixes for
issues reported by security researchers and Sashiko
- netfilter: same thing, a lot of small security-ish fixes all over
the place, nothing really stands out

Flush the current TLB when xAVIC *or* x2AVIC is activated, as KVM is
(apparently) responsible for purging TLB entries when transitioning from
xAVIC to x2AVIC. The APM says a whole lot of nothing about TLB flushing
with respect to (x2)AVIC, but empirical data strongly suggests hardware
also does a whole lot of nothing.
Failure to flush the TLB when enabling x2AVIC can lead to guest accesses
to the APIC base address getting incorrectly redirected to the virtual
APIC page. The flaw most visibly manifests as failures in KVM-Unit-Test's
verify_disabled_apic_mmio() testcase when x2APIC is enabled (though for
reasons unknown, the test only reliably fails with EFI builds).

Move KVM's stuffing of GUEST_PENDING_DBG_EXCEPTIONS.BS when RFLAGS.TF=1 and
MOV/POP SS or STI blocking is active into the exception injection code so
that KVM fixes up the VMCS for all injected #DBs, not only those that are
reflected back into the guest after #DB interception. E.g. if KVM queues
a #DB in the emulator, or more importantly if userspace does save/restore
exactly on the #DB+shadow boundary, then KVM needs to massage the VMCS to
avoid the VM-Entry consistency check.
Opportunistically update the wording of the comment to describe the
behavior as a workaround of flawed CPU behavior/architecture, to make it
clear that the *only* thing KVM is doing is fudging around a consistency
check. Per the SDM:
There are no pending debug exceptions after VM entry if any of the
following are true:
* The VM entry is vectoring with one of the following interruption
types: external interrupt, non-maskable interrupt (NMI), hardware
exception, or privileged software exception.
I.e. forcing GUEST_PENDING_DBG_EXCEPTIONS.BS does *not* impact guest-
visible behavior.

Pull ring-buffer fixes from Steven Rostedt:
- Fix reporting MISSED EVENTS in trace iterator
When the "trace" file is read with tracing enabled, if the writer
were to pass the iterator reader, it resets, sets a "missed_events"
flag and continues. The tracing output checks for missed events and
if there are some, it prints out "[LOST EVENTS]" to let the user know
events were dropped.
But the clearing of the missed_events happened when the tracing
system queried the ring buffer iterator about missed events. This was
premature as the ring buffer is per CPU, and the tracing code reads
all the CPU buffers and checks for missed events when it is read. If
the CPU iterator that had missed events isn't printed next, the
output for the LOST EVENTS is lost.
Clear the missed_events flag when the iterator moves to the next
event and not when the missed_events flag is queried. Also clear it
on reset.
- Flush and stop the persistent ring buffer on panic
On panic the persistent ring buffer is used to debug what caused the
panic. But on some architectures, it requires flushing the memory
from cache, otherwise, the ring buffer persistent memory may not have
the last events and this could also cause the ring buffer to be
corrupted on the next boot.
- Fix nr_subbufs initialization in simple_ring_buffer_init_mm
The remote simple ring buffer meta data nr_subbufs is initialized too
early and gets cleared later on, making it zero and not reflect the
actual number of sub-buffers.
- Fix unload_page for simple_ring_buffer init rollback
On error, the pages loaded need to be unloaded. To unload a page it
is expected that: page = load_page(va); -> unload_page(page). But the
code was doing: unload_page(va) and not unload_page(page).
- Create output file from cmd_check_undefined
The check for undefined symbols checks if the file *.o.checked exists
and if so it skips doing the work. But the *.o.checked file never was
created making every build do the work even when it was already done
previously.
