    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 
and
    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 
it
    required regs->rip to have its old value as a cross-check that the right 
word
    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 
to
    ensure that the shadow stack is updated too.
    
    Fixes: 209fb9919b50 ("x86/extable: Adjust extable handling to be shadow 
stack compatible")

    x86/ACPI: Insert missing newlines into FACS error messages
    
    Booting Xen as a PVH guest currently yields:
    
      (XEN) ACPI: SLEEP INFO: pm1x_cnt[1:b004,1:0], pm1x_evt[1:b000,1:0]
      (XEN) ACPI: FACS is not 64-byte aligned: 0xfc001010<2>ACPI: 
wakeup_vec[fc00101c], vec_size[20]
      (XEN) ACPI: Local APIC address 0xfee00000
    
    Insert newlines as appropriate.
