Drop the second snapshot of mmu_invalidate_seq in kvm_faultin_pfn(). Before checking the mismatch of private vs. shared, mmu_invalidate_seq is saved to fault->mmu_seq, which can be used to detect an invalidation related to the gfn occurred, i.e. KVM will not install a mapping in page table if fault->mmu_seq != mmu_invalidate_seq. Currently there is a second snapshot of mmu_invalidate_seq, which may not be same as the first snapshot in kvm_faultin_pfn(), i.e. the gfn attribute may be changed between the two snapshots, but the gfn may be mapped in page table without hindrance. Therefore, drop the second snapshot as it has no obvious benefits.

KVM (and pKVM) do not support SME guests. Therefore KVM ensures that the host's SME state is flushed and that SME controls for enabling access to ZA storage and for streaming are disabled. pKVM needs to protect against a buggy/malicious host. Ensure that it wouldn't run a guest when protected mode is enabled should any of the SME controls be enabled.

When running in protected mode we don't want to leak protected guest state to the host, including whether a guest has used fpsimd/sve.

Protected mode needs to maintain (save/restore) the host's sve state, rather than relying on the host kernel to do that. This is to avoid leaking information to the host about guests and the type of operations they are performing. As a first step towards that, allocate memory mapped at hyp, per cpu, for the host sve state. The following patch will use this memory to save/restore the host state.

The same traps controlled by CPTR_EL2 or CPACR_EL1 need to be toggled in different parts of the code, but the exact bits and their polarity differ between these two formats and the mode (vhe/nvhe/hvhe). To reduce the amount of duplicated code and the chance of getting the wrong bit/polarity or missing a field, abstract the set/clear of CPTR_EL2 bits behind a helper. Since (h)VHE is the way of the future, use the CPACR_EL1 format, which is a subset of the VHE CPTR_EL2, as a reference. No functional change intended.

Remove support for specifying a static local APIC timer advancement value, and instead present a read-only boolean parameter to let userspace enable or disable KVM's dynamic APIC timer advancement. Realistically, it's all but impossible for userspace to specify an advancement that is more precise than what KVM's adaptive tuning can provide. E.g. a static value needs to be tuned for the exact hardware and kernel, and if KVM is using hrtimers, likely requires additional tuning for the exact configuration of the entire system. Dropping support for a userspace provided value also fixes several flaws in the interface. E.g. KVM interprets a negative value other than -1 as a large advancement, toggling between a negative and positive value yields unpredictable behavior as vCPUs will switch from dynamic to static advancement, changing the advancement in the middle of VM creation can result in different values for vCPUs within a VM, etc. Those flaws are mostly fixable, but there's almost no justification for taking on yet more complexity (it's minimal complexity, but still non-zero). The only arguments against using KVM's adaptive tuning is if a setup needs a higher maximum, or if the adjustments are too reactive, but those are arguments for letting userspace control the absolute max advancement and the granularity of each adjustment, e.g. similar to how KVM provides knobs for halt polling.

As documented in APM[1], LBR Virtualization must be enabled for SEV-ES guests. Although KVM currently enforces LBRV for SEV-ES guests, there are multiple issues with it: o MSR_IA32_DEBUGCTLMSR is still intercepted. Since MSR_IA32_DEBUGCTLMSR interception is used to dynamically toggle LBRV for performance reasons, this can be fatal for SEV-ES guests. For ex SEV-ES guest on Zen3: [guest ~]# wrmsr 0x1d9 0x4 KVM: entry failed, hardware error 0xffffffff EAX=00000004 EBX=00000000 ECX=000001d9 EDX=00000000 Fix this by never intercepting MSR_IA32_DEBUGCTLMSR for SEV-ES guests. No additional save/restore logic is required since MSR_IA32_DEBUGCTLMSR is of swap type A. o KVM will disable LBRV if userspace sets MSR_IA32_DEBUGCTLMSR before the VMSA is encrypted. Fix this by moving LBRV enablement code post VMSA encryption.

KVM currently allows userspace to read/write MSRs even after the VMSA is encrypted. This can cause unintentional issues if MSR access has side- effects. For ex, while migrating a guest, userspace could attempt to migrate MSR_IA32_DEBUGCTLMSR and end up unintentionally disabling LBRV on the target. Fix this by preventing access to those MSRs which are context switched via the VMSA, once the VMSA is encrypted.

At the same time, just keep CONFIG_ACPI to prevent potential build errors in future, and give a signal to indicate the code is ACPI-specific.
