c822f58a4f x86/apic: Populate .read()/.write() callbacks of Secure AVIC driver
Add read() and write() APIC callback functions to read and write the x2APIC
registers directly from the guest APIC backing page of a vCPU.

The x2APIC registers are mapped at an offset within the guest APIC backing
page which is the same as their x2APIC MMIO offset. Secure AVIC adds new
registers such as ALLOWED_IRRs (which are at 4-byte offset within the IRR
register offset range) and NMI_REQ to the APIC register space.

When Secure AVIC is enabled, accessing the guest's APIC registers through
RD/WRMSR results in a #VC exception (for non-accelerated register accesses)
with error code VMEXIT_AVIC_NOACCEL.

The #VC exception handler can read/write the x2APIC register in the guest APIC
backing page to complete the RDMSR/WRMSR. Since doing this would increase the
latency of accessing the x2APIC registers, instead of doing RDMSR/WRMSR based
register accesses and handling reads/writes in the #VC exception, directly
read/write the APIC registers from/to the guest APIC backing page of the vCPU
in read() and write() callbacks of the Secure AVIC APIC driver.

b8c3c9f5d0 x86/apic: Initialize Secure AVIC APIC backing page
With Secure AVIC, the APIC backing page is owned and managed by the guest.
Allocate and initialize APIC backing page for all guest CPUs.

The NPT entry for a vCPU's APIC backing page must always be present when the
vCPU is running in order for Secure AVIC to function. A VMEXIT_BUSY is
returned on VMRUN and the vCPU cannot be resumed otherwise.

To handle this, notify GPA of the vCPU's APIC backing page to the hypervisor
by using the SVM_VMGEXIT_SECURE_AVIC GHCB protocol event. Before executing
VMRUN, the hypervisor makes use of this information to make sure the APIC
backing page is mapped in the NPT.

273be31e5a arm64: dts: apple: Add devicetreee for t8112-j415
The 15-inch M2 MacBook Air was released a year after the 13-inch one
thus missed in initial submission of devicetrees for M2 based devices.
It is currently a copy of t8112-j413 with edited identifiers but will
eventually differ in a meaningful way. It has for example a different
speaker configuration than the 13-inch model.

6e08cdd604 arm64: dts: apple: t8103-j457: Fix PCIe ethernet iommu-map
PCIe `port01` of t8103-j457 (iMac, M1, 2 USB-C ports, 2021) is unused
and disabled. Linux' PCI subsystem assigns the ethernet nic from
`port02` to bus 02. This results into assigning `pcie0_dart_1` from the
disabled port as iommu. The `pcie0_dart_1` instance is disabled and
probably fused off (it is on the M2 Pro Mac mini which has a disabled
PCIe port as well).
Without iommu the ethernet nic is not expected work.
Adjusts the "bus-range" and the PCIe devices "reg" property to PCI
subsystem's bus number.

33d7ecbf69 iio: frequency: adf4350: Fix prescaler usage.
The ADF4350/1 features a programmable dual-modulus prescaler of 4/5 or 8/9.
When set to 4/5, the maximum RF frequency allowed is 3 GHz.
Therefore, when operating the ADF4351 above 3 GHz, this must be set to 8/9.
In this context not the RF output frequency is meant
- it's the VCO frequency.

Therefore move the prescaler selection after we derived the VCO frequency
from the desired RF output frequency.

This BUG may have caused PLL lock instabilities when operating the VCO at
the very high range close to 4.4 GHz.

batadv_nc_skb_decode_packet() trusts coded_len and checks only against
skb->len. XOR starts at sizeof(struct batadv_unicast_packet), reducing
payload headroom, and the source skb length is not verified, allowing an
out-of-bounds read and a small out-of-bounds write.

Validate that coded_len fits within the payload area of both destination
and source sk_buffs before XORing.

80770fccb7 clk: samsung: Add clock PLL support for ARTPEC-8 SoC
Add below clock PLL support for Axis ARTPEC-8 SoC platform:
- pll_1017x: Integer PLL with mid frequency FVCO (950 to 2400 MHz)
             This is used in ARTPEC-8 SoC for shared PLL

- pll_1031x: Integer/Fractional PLL with mid frequency FVCO
             (600 to 1200 MHz)
             This is used in ARTPEC-8 SoC for Audio PLL

FOUT calculation for pll_1017x and pll_1031x:
FOUT = (MDIV x FIN)/(PDIV x 2^SDIV) for integer PLL
FOUT = (((MDIV + KDIV)/65536) x FIN)/(PDIV x 2^SDIV) for fractional PLL

187b114a2a wifi: iwlwifi: carefully select the PNVM source
For newer device, and from API 100 (core 97), the PNVM should be taken
from the .ucode file, and not from an external .pnvm file.

In the current logic, if the PNVM doesn't exist in the .ucode file, we
fallback to fetching the .ucode file. This is wrong and hides bugs.

This fallback was needed for (a) old devices and (b) for newer
devices with an old API.

Since we no longer support those old APIs, (b) is not longer relevant.
We can, according to the device, select the right PNVM source
and fail if we couldn't find the PNVM there.

Add clear logic to select the expected PNVM source, and print an error
if we couldn't get the PNVM from there.

e349241b97 x86/sev: Run RMPADJUST on SVSM calling area page to test VMPL
Determining the VMPL at which the kernel runs involves performing a RMPADJUST
operation on an arbitrary page of memory, and observing whether it succeeds.

The use of boot_ghcb_page in the core kernel in this case is completely
arbitrary, but results in the need to provide a PIC alias for it. So use
boot_svsm_ca_page instead, which already needs this alias for other reasons.

7cb7b6de9c x86/sev: Use MSR protocol only for early SVSM PVALIDATE call
The early page state change API performs an SVSM call to PVALIDATE each page
when running under a SVSM, and this involves either a GHCB page based call or
a call based on the MSR protocol.

The GHCB page based variant involves VA to PA translation of the GHCB address,
and this is best avoided in the startup code, where virtual addresses are
ambiguous (1:1 or kernel virtual).

As this is the last remaining occurrence of svsm_perform_call_protocol() in
the startup code, switch to the MSR protocol exclusively in this particular
case, so that the GHCB based plumbing can be moved out of the startup code
entirely in a subsequent patch.

c15a4705d5 x86/sev: Use MSR protocol for remapping SVSM calling area
As the preceding code comment already indicates, remapping the SVSM
calling area occurs long before the GHCB page is configured, and so
calling svsm_perform_call_protocol() is guaranteed to result in a call
to svsm_perform_msr_protocol().

So just call the latter directly. This allows most of the GHCB based API
infrastructure to be moved out of the startup code in a subsequent
patch.
