Will Deacon f85279b4bd arm64: KVM: Save/restore the host SPE state when entering/leaving a VM ... The SPE buffer is virtually addressed, using the page tables of the CPU MMU. Unusually, this means that the EL0/1 page table may be live whilst we're executing at EL2 on non-VHE configurations. When VHE is in use, we can use the same property to profile the guest behind its back. This patch adds the relevant disabling and flushing code to KVM so that the host can make use of SPE without corrupting guest memory, and any attempts by a guest to use SPE will result in a trap.
