commit 35727551c0703493a2240e967cffc3063b13d49c
Author: Andrew Cooper <andrew.cooper3@xxxxxxxxxx>

    x86/cet: Fix shskt manipulation error with BUGFRAME_{warn,run_fn}
    This was a clear oversight in the original CET work.  The BUGFRAME_run_fn 
    BUGFRAME_warn paths update regs->rip without an equivalent adjustment to the
    shadow stack, causing IRET to suffer #CP because of the mismatch.
    One subtle, and therefore fragile, aspect of extable_shstk_fixup() was that 
    required regs->rip to have its old value as a cross-check that the right 
    in the shadow stack was being edited.
    Rework extable_shstk_fixup() into fixup_exception_return() which takes
    ownership of the update to both the regular and shadow stacks, ensuring that
    the regs->rip update is ordered correctly.
    Use the new fixup_exception_return() for BUGFRAME_run_fn and BUGFRAME_warn 
    ensure that the shadow stack is updated too.
    Fixes: 209fb9919b50 ("x86/extable: Adjust extable handling to be shadow 
stack compatible")
