H A D | kfence.h | 58b6fed8 Wed Aug 09 03:07:13 CDT 2023 Linus Walleij <linus.walleij@linaro.org> powerpc: Make virt_to_pfn() a static inline
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.
Move the virt_to_pfn() and related functions below the declaration of __pa() so it compiles.
For symmetry do the same with pfn_to_kaddr().
As the file is included right into the linker file, we need to surround the functions with ifndef __ASSEMBLY__ so we don't cause compilation errors.
The conversion moreover exposes the fact that pmd_page_vaddr() was returning an unsigned long rather than a const void * as could be expected, so all the sites defining pmd_page_vaddr() had to be augmented as well.
Finally the KVM code in book3s_64_mmu_hv.c was passing an unsigned int to virt_to_phys() so fix that up with a cast so the result compiles.
