[PATCH 0/5] mm: Pass pointers to page accessors

In a recent change to the Arm architecture with the end goal
of removing highmem we need to convert virt_to_phys() and
virt_to_pfn() to static inline functions.

This will make them strongly typed.

However since virt_to_* is always implemented as macros they
have become polymorphic and accept both (void *) and
e.g. unsigned long as arguments.

Other functions such as virt_to_page() simply wrap
virt_to_pfn() and get affected indirectly.

To be able to proceed, patch mm to use (void *) as argument
to affected functions in all instances.

Linus Walleij (5):
lib/test_free_pages.c: Pass a pointer to virt_to_page()
mm/highmem: Pass a pointer to virt_to_page()
mm: kfence: Pass a pointer to virt_to_page()
mm: gup: Pass a pointer to virt_to_page()
mm: nommu: Pass a pointer to virt_to_page()
