arm64: mm: Simplify __flush_tlb_range_limit_excess()
__flush_tlb_range_limit_excess() is unnecessarily complicated:
- It takes a 'start', 'end' and 'pages' argument, whereas it only
needs 'pages' (which the caller has computed from the other two
arguments!).
- It erroneously compares 'pages' with MAX_TLBI_RANGE_PAGES when
the system doesn't support range-based invalidation but the range to
be invalidated would result in fewer than MAX_DVM_OPS invalidations.
Simplify the function so that it no longer takes the 'start' and 'end'
arguments and only considers the MAX_TLBI_RANGE_PAGES threshold on
systems that implement range-based invalidation.
