Merge tag 'x86_entry_for_6.18-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git...

Pull x86 entry updates from Dave Hansen:
 "A pair of x86/entry updates.

  The FRED one adjusts the kernel to the latest spec. The spec change
  prevents attackers from abusing kernel entry points.

  The second one came about because of the LASS work[1]. It moves the
  vsyscall emulation code away from depending on X86_PF_INSTR which is
  not available on some CPUs. Those CPUs are pretty obscure these days,
  but this still seems like the right thing to do. It also makes this
  code consistent with some things that the LASS code is going to do.

   - Use RIP instead of X86_PF_INSTR for vsyscall emulation

   - Remove ENDBR64 from FRED entry points"
