SAVE_ALL and RESTORE_ALL macros for !CONFIG_X86_64 were
introduced in commit:

  1a338ac3 commit ('sched, x86: Optimize the preempt_schedule() call')

... and were used in the ___preempt_schedule() and ___preempt_schedule_context()
functions from the arch/x86/kernel/preempt.S.

But the arch/x86/kernel/preempt.S file was removed in the following commit:

  0ad6e3c5 commit ('x86: Speed up ___preempt_schedule*() by using THUNK helpers')

The ___preempt_schedule()/___preempt_schedule_context() functions were
reimplemeted and do not use SAVE_ALL/RESTORE_ALL anymore.

These macros have no users anymore, so we can remove them.
