Pull perf fixes from Borislav Petkov:
- Avoid a crash on a heterogeneous machine where not all cores support
the same hw events features
- Avoid a deadlock when throttling events
- Document the perf event states more
- Make sure a number of perf paths switching off or rescheduling events
call perf_cgroup_event_disable()
- Make sure perf does task sampling before its userspace mapping is
torn down, and not after

Pull kvm fixes from Paolo Bonzini:
"ARM:
- Fix another set of FP/SIMD/SVE bugs affecting NV, and plugging some
missing synchronisation
- A small fix for the irqbypass hook fixes, tightening the check and
ensuring that we only deal with MSI for both the old and the new
route entry
- Rework the way the shadow LRs are addressed in a nesting
configuration, plugging an embarrassing bug as well as simplifying
the whole process
- Add yet another fix for the dreaded arch_timer_edge_cases selftest
RISC-V:
- Fix the size parameter check in SBI SFENCE calls
- Don't treat SBI HFENCE calls as NOPs
x86 TDX:
- Complete API for handling complex TDVMCALLs in userspace.
This was delayed because the spec lacked a way for userspace to
deny supporting these calls; the new exit code is now approved"

Exit to userspace for TDG.VP.VMCALL<GetTdVmCallInfo> via KVM_EXIT_TDX,
to allow userspace to provide information about the support of
TDVMCALLs when r12 is 1 for the TDVMCALLs beyond the GHCI base API.
GHCI spec defines the GHCI base TDVMCALLs: <GetTdVmCallInfo>, <MapGPA>,
<ReportFatalError>, <Instruction.CPUID>, <#VE.RequestMMIO>,
<Instruction.HLT>, <Instruction.IO>, <Instruction.RDMSR> and
<Instruction.WRMSR>. They must be supported by VMM to support TDX guests.
For GetTdVmCallInfo
- When leaf (r12) to enumerate TDVMCALL functionality is set to 0,
successful execution indicates all GHCI base TDVMCALLs listed above are
supported.
Update the KVM TDX document with the set of the GHCI base APIs.
- When leaf (r12) to enumerate TDVMCALL functionality is set to 1, it
indicates the TDX guest is querying the supported TDVMCALLs beyond
the GHCI base TDVMCALLs.
Exit to userspace to let userspace set the TDVMCALL sub-function bit(s)
accordingly to the leaf outputs. KVM could set the TDVMCALL bit(s)
supported by itself when the TDVMCALLs don't need support from userspace
after returning from userspace and before entering guest. Currently, no
such TDVMCALLs implemented, KVM just sets the values returned from
userspace.

Handle TDVMCALL for GetQuote to generate a TD-Quote.
GetQuote is a doorbell-like interface used by TDX guests to request VMM
to generate a TD-Quote signed by a service hosting TD-Quoting Enclave
operating on the host. A TDX guest passes a TD Report (TDREPORT_STRUCT) in
a shared-memory area as parameter. Host VMM can access it and queue the
operation for a service hosting TD-Quoting enclave. When completed, the
Quote is returned via the same shared-memory area.
KVM only checks the GPA from the TDX guest has the shared-bit set and drops
the shared-bit before exiting to userspace to avoid bleeding the shared-bit
into KVM's exit ABI. KVM forwards the request to userspace VMM (e.g. QEMU)
and userspace VMM queues the operation asynchronously. KVM sets the return
code according to the 'ret' field set by userspace to notify the TDX guest
whether the request has been queued successfully or not. When the request
has been queued successfully, the TDX guest can poll the status field in
the shared-memory area to check whether the Quote generation is completed
or not. When completed, the generated Quote is returned via the same
buffer.
Add KVM_EXIT_TDX as a new exit reason to userspace. Userspace is
required to handle the KVM exit reason as the initial support for TDX,
by reentering KVM to ensure that the TDVMCALL is complete. While at it,
add a note that KVM_EXIT_HYPERCALL also requires reentry with KVM_RUN.

Add the new TDVMCALL status code TDVMCALL_STATUS_SUBFUNC_UNSUPPORTED and
return it for unimplemented TDVMCALL subfunctions.
Returning TDVMCALL_STATUS_INVALID_OPERAND when a subfunction is not
implemented is vague because TDX guests can't tell the error is due to
the subfunction is not supported or an invalid input of the subfunction.
New GHCI spec adds TDVMCALL_STATUS_SUBFUNC_UNSUPPORTED to avoid the
ambiguity. Use it instead of TDVMCALL_STATUS_INVALID_OPERAND.
Before the change, for common guest implementations, when a TDX guest
receives TDVMCALL_STATUS_INVALID_OPERAND, it has two cases:
1. Some operand is invalid. It could change the operand to another value
retry.
2. The subfunction is not supported.
For case 1, an invalid operand usually means the guest implementation bug.
Since the TDX guest can't tell which case is, the best practice for
handling TDVMCALL_STATUS_INVALID_OPERAND is stopping calling such leaf,
treating the failure as fatal if the TDVMCALL is essential or ignoring
it if the TDVMCALL is optional.
With this change, TDVMCALL_STATUS_SUBFUNC_UNSUPPORTED could be sent to
old TDX guest that do not know about it, but it is expected that the
guest will make the same action as TDVMCALL_STATUS_INVALID_OPERAND.
Currently, no known TDX guest checks TDVMCALL_STATUS_INVALID_OPERAND
specifically; for example Linux just checks for success.

Add arch_stack_walk_reliable(), which will be used during kernel live
patching to detect when threads have completed executing old versions of
functions.
Note that arch_stack_walk_reliable() only needs to guarantee that it
returns an error code when it cannot provide a reliable stacktrace. It
is not required to provide a reliable stacktrace in all scenarios so
long as it returns said error code.
At present we can only reliably unwind up to an exception boundary. In
future we should be able to improve this with additional data from the
compiler (e.g. sframe).

To enable late module patching, livepatch modules need to be able to
apply some of their relocations well after being loaded. In this
scenario however, the livepatch module text and data is already RX-only,
so special treatment is needed to make the late relocations possible. To
do this, use the text-poking API for these late relocations.
This patch is partially based off commit 88fc078a7a8f6 ("x86/module: Use
text_poke() for late relocations").

Ringneck
The Haikou Video Demo adapter has a proprietary connector for a camera
module which has an OV5675 camera sensor and a companion DW9714 focus
lens driver.
This adds support for the camera module on PX30 Ringneck module fitted
on a Haikou devkit with the Haikou Video Demo adapter.

This will make it slightly easier for Device Trees (and Overlays) to
link the ISP controller to a video input such as a CSI camera while also
bringing it closer to what's been done already for the DSI controller.

dtc complains with the following message for DTSes which use the ISP:
arch/arm64/boot/dts/rockchip/px30.dtsi:1272.19-1276.6: Warning (graph_child_address): /isp@ff4a0000/ports/port@0: graph node has single child node 'endpoint@0', #address-cells/#size-cells are not necessary
Typically, it is expected from the device DTS(I) to update the SoC DTSI
nodes if they have more than one endpoint, so let's assume there's only
one endpoint in port@0 by default, instead of forcing board DTS(I)s to
/delete-property/ address-cells and size-cells to make dtc happy.
Because PX30 PP1516/EVB's endpoint@0 is the only endpoint and
considering its parent node now has no address-cells property, dtc
complains (same messages for PX30 EVB):
arch/arm64/boot/dts/rockchip/px30-pp1516.dtsi:447.29-451.6: Warning (avoid_default_addr_size): /isp@ff4a0000/ports/port@0/endpoint@0: Relying on default #address-cells value

arch/arm64/boot/dts/rockchip/px30-pp1516.dtsi:447.29-451.6: Warning (graph_endpoint): /isp@ff4a0000/ports/port@0/endpoint@0: graph node '#address-cells' is -1, must be 1
arch/arm64/boot/dts/rockchip/px30-pp1516.dtsi:447.29-451.6: Warning (graph_endpoint): /isp@ff4a0000/ports/port@0/endpoint@0: graph node '#size-cells' is -1, must be 0
arch/arm64/boot/dts/rockchip/px30-pp1516-ltk050h3146w-a2.dtb: Warning (graph_child_address): Failed prerequisite 'graph_endpoint'
so we fix that by removing the reg property. dtc still complains (same
messages for PX30 EVB):
arch/arm64/boot/dts/rockchip/px30-pp1516.dtsi:447.29-450.6: Warning (unit_address_vs_reg): /isp@ff4a0000/ports/port@0/endpoint@0: node has a unit name, but no reg or ranges property
so we also remove the @0 suffix off the node name.

S32G3 and S32G2 have the same 6 SPI devices, add the DT entries. Devices
are all the same except spi0 has 8 chip selects instead of 5. Clock
settings for the chip rely on ATF Firmware [1].

Set ethernet1 alias to EQOS interface on phyBOARD-Segin-i.MX93 marking

Move alias for ethernet0 interface to the phyCORE-i.MX93 SoM include
file. The reason behind it is that the physical location of the PHY chip
connected to FEC interface is on the SoM itself and alias thus belongs
into the SoM device-tree. Consequently, it can be used by all boards
based on the phyCORE-i.MX93 SoM (phyBOARD-Segin and phyBOARD-Nash).
This also enables us to mark FEC interface as the primary / first for
networking in the bootloader and systemd (predictable interface names).
