Add prototypes required to fix the following 'make LLVM=1 W=1'
build errors:
arch/x86/entry/common.c:238:24: error: no previous prototype for
function 'do_SYSENTER_32' [-Werror,-Wmissing-prototypes]
__visible noinstr long do_SYSENTER_32(struct pt_regs *regs)
^
arch/x86/entry/common.c:302:24: error: no previous prototype for
function 'xen_pv_evtchn_do_upcall' [-Werror,-Wmissing-prototypes]
__visible noinstr void xen_pv_evtchn_do_upcall(struct pt_regs *regs)
