Looking at the Neoverse N1 errata document, it is not clear to me
why the TLBI repeat workaround is not applied for TLB flush by VA.

The TBL flush by VA helpers are used in flush_xen_tlb_range_va_local()

s/TBL/TLB/

and flush_xen_tlb_range_va(). So if the range size if a fixed size smaller

NIT: is a fixed size

Thanks. I will fix it on commit unless there is another round needed.

Cheers,
