Linus Torvalds 82ff316456 ARM:
- Large set of fixes for vector handling, specially in the interactions
   between host and guest state. This fixes a number of bugs affecting
   actual deployments, and greatly simplifies the FP/SIMD/SVE handling.
   Thanks to Mark Rutland for dealing with this thankless task.
 
 - Fix an ugly race between vcpu and vgic creation/init, resulting in
   unexpected behaviours.
 
 - Fix use of kernel VAs at EL2 when emulating timers with nVHE.
 
 - Small set of pKVM improvements and cleanups.
 
 x86:
 
 - Fix broken SNP support with KVM module built-in, ensuring the PSP
   module is initialized before KVM even when the module infrastructure
   cannot be used to order initcalls
 
 - Reject Hyper-V SEND_IPI hypercalls if the local APIC isn't being emulated
   by KVM to fix a NULL pointer dereference.
 
 - Enter guest mode (L2) from KVM's perspective before initializing the vCPU's
   nested NPT MMU so that the MMU is properly tagged for L2, not L1.
 
 - Load the guest's DR6 outside of the innermost .vcpu_run() loop, as the
   guest's value may be stale if a VM-Exit is handled in the fastpath.
