Xiao Guangrong 1be0e61c1f KVM, pkeys: save/restore PKRU when guest/host switches ... Currently XSAVE state of host is not restored after VM-exit and PKRU is managed by XSAVE so the PKRU from guest is still controlling the memory access even if the CPU is running the code of host. This is not safe as KVM needs to access the memory of userspace (e,g QEMU) to do some emulation. So we save/restore PKRU when guest/host switches.
