Re: [PATCH 1/6] set_memory: add number of pages parameter to set_direct_map APIs
| Newsgroups | org.kernel.vger.linux-s390 |

| Message-ID | <[email protected]> |
> When set_direct_map APIs were introduced by the commit d253ca0c3865
> ("x86/mm/cpa: Add set_direct_map_*() functions") the single page
> parameter made sense because the initial callers (vmalloc and
> hibernation) had sets of unsorted struct pages that required changes of
> their mappings in the direct map.
>
> Since there is an increasing demand for direct map manipulation and it
> is also desirable to be able to update larger physically contiguous
> mappings, for example an entire large folio, extend set_direct_map APIs
> to receive number of pages parameter.
>
> As there is still only a handful of callers, change the existing
> functions directly and update all the call sites rather than adding
> wrappers for single page case.
