lib/test_free_pages.c: pass a pointer to virt_to_page()
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.
This patch (of 5):
A pointer into virtual memory is represented by a (void *) not an u32, so
the compiler warns:
lib/test_free_pages.c:20:50: warning: passing argument 1
of 'virt_to_pfn' makes pointer from integer without a
cast [-Wint-conversion]
Fix this with an explicit cast.
