[PATCH 1/5] mm: Introduce a common definition of mk_pte()
Matthew Wilcox (Oracle)
willy at infradead.org
Wed Aug 14 08:44:21 PDT 2024
Most architectures simply call pfn_pte(). Centralise that as the normal
definition and remove the definition of mk_pte() from the architectures
which have either that exact definition or something similar.
