Upd: Fpstate Vso

The Linux kernel uses similar structures to manage FPU state for both the host and virtual machines. For example, the kernel's fpstate_init_user() function is responsible for initializing the FPU state for user-space tasks and KVM (Kernel-based Virtual Machine) guests. In KVM, the "guest fpstate" is initialized to a known safe state when a virtual CPU is created. Mistakes in this initialization can cause subtle bugs, such as the init_fpstate incorrectly indicating the inclusion of dynamic states (like the 8KB AMX TILE_DATA state), leading to memory errors that are hard to diagnose.
