Peter Zijlstra 8f93402b92 x86/ibt,entry: Sprinkle ENDBR dust 
Kernel entry points should be having ENDBR on for IBT configs.

The SYSCALL entry points are found through taking their respective
address in order to program them in the MSRs, while the exception
entry points are found through UNWIND_HINT_IRET_REGS.

The rule is that any UNWIND_HINT_IRET_REGS at sym+0 should have an
ENDBR, see the later objtool ibt validation patch.
