2023-08-16s390/mm: make virt_to_pfn() a static inlineLinus Walleij1-1/+1
Making virt_to_pfn() a static inline taking a strongly typed (const void *) makes the contract of a passing a pointer of that type to the function explicit and exposes any misuse of the macro virt_to_pfn() acting polymorphic and accepting many types such as (void *), (unitptr_t) or (unsigned long) as arguments without warnings. For symmetry do the same with pfn_to_virt() reflecting the current layout in asm-generic/page.h. Doing this reveals a number of offenders in the arch code and the S390-specific drivers, so just bite the bullet and fix up all of those as well.
