2023-12-07x86/coco: Disable 32-bit emulation by default on TDX and SEVKirill A. Shutemov
The INT 0x80 instruction is used for 32-bit x86 Linux syscalls. The kernel expects to receive a software interrupt as a result of the INT 0x80 instruction. However, an external interrupt on the same vector triggers the same handler. The kernel interprets an external interrupt on vector 0x80 as a 32-bit system call that came from userspace. A VMM can inject external interrupts on any arbitrary vector at any time. This remains true even for TDX and SEV guests where the VMM is untrusted. Put together, this allows an untrusted VMM to trigger int80 syscall handling at any given point. The content of the guest register file at that moment defines what syscall is triggered and its arguments. It opens the guest OS to manipulation from the VMM side. Disable 32-bit emulation by default for TDX and SEV. User can override it with the ia32_emulation=y command line option.

2023-12-07KVM: x86: Make Hyper-V emulation optionalVitaly Kuznetsov
Hyper-V emulation in KVM is a fairly big chunk and in some cases it may be desirable to not compile it in to reduce module sizes as well as the attack surface. Introduce CONFIG_KVM_HYPERV option to make it possible. Note, there's room for further nVMX/nSVM code optimizations when !CONFIG_KVM_HYPERV, this will be done in follow-up patches. Reorganize Makefile a bit so all CONFIG_HYPERV and CONFIG_KVM_HYPERV files are grouped together.

A643 (A635 speedbin 0xac) tops out at 812 MHz. Fill in the opp-supported-hw appropriately. Note that fuseval 0xac is referred to as speedbin 1 downstream, but that was already in use upstream, so 2 was chosen instead.

2023-12-07arm64: dts: qcom: sc7280: Fix up GPU SIDsKonrad Dybcio
GPU_SMMU SID 1 is meant for Adreno LPAC (Low Priority Async Compute). On platforms that support it (in firmware), it is necessary to describe that link, or Adreno register access will hang the board. The current settings are functionally identical, *but* due to what is likely hardcoded security policies, the secure firmware rejects them, resulting in the board hanging. To avoid that, alter the settings such that SID 0 and 1 are described separately.
