Chris von Recklinghausen 468dfcb009 mm: kfence: pass a pointer to virt_to_page() 
Bugzilla: https://bugzilla.redhat.com/2160210

commit 9e7ee421ac1f8d7fe350d2dee87e31919e9cba84
Author: Linus Walleij <linus.walleij@linaro.org>
Date:   Thu Jun 30 10:41:22 2022 +0200

    mm: kfence: pass a pointer to virt_to_page()

    Functions that work on a pointer to virtual memory such as virt_to_pfn()
    and users of that function such as virt_to_page() are supposed to pass a
    pointer to virtual memory, ideally a (void *) or other pointer.  However
    since many architectures implement virt_to_pfn() as a macro, this function
    becomes polymorphic and accepts both a (unsigned long) and a (void *).

    If we instead implement a proper virt_to_pfn(void *addr) function the
    following happens (occurred on arch/arm):

    mm/kfence/core.c:558:30: warning: passing argument 1
      of 'virt_to_pfn' makes pointer from integer without a
      cast [-Wint-conversion]

    In one case we can refer to __kfence_pool directly (and that is a proper
    (char *) pointer) and in the other call site we use an explicit cast.
