    mm: add PTE pointer parameter to flush_tlb_fix_spurious_fault() · 99c29133
    Gerald Schaefer authored Mar 06, 2023
    s390 can do more fine-grained handling of spurious TLB protection faults,
    when there also is the PTE pointer available.
    
    Therefore, pass on the PTE pointer to flush_tlb_fix_spurious_fault() as an
    additional parameter.
    
    This will add no functional change to other architectures, but those with
    private flush_tlb_fix_spurious_fault() implementations need to be made
    aware of the new parameter.
