Geert Uytterhoeven a65a802aad m68k: Fix virt_addr_valid() W=1 compiler warnings 
If CONFIG_DEBUG_SG=y, and CONFIG_MMU=y:

    include/linux/scatterlist.h: In function ‘sg_set_buf’:
    arch/m68k/include/asm/page_mm.h:174:49: warning: ordered comparison of pointer with null pointer [-Wextra]
      174 | #define virt_addr_valid(kaddr) ((void *)(kaddr) >= (void *)PAGE_OFFSET && (void *)(kaddr) < high_memory)
	  |                                                 ^~

or CONFIG_MMU=n:

    include/linux/scatterlist.h: In function ‘sg_set_buf’:
    arch/m68k/include/asm/page_no.h:33:50: warning: ordered comparison of pointer with null pointer [-Wextra]
       33 | #define virt_addr_valid(kaddr) (((void *)(kaddr) >= (void *)PAGE_OFFSET) && \
	  |                                                  ^~

Fix this by doing the comparison in the "unsigned long" instead of the
"void *" domain.

Note that for now this is only seen when compiling btrfs, due to commit
e9aa7c285d ("btrfs: enable W=1 checks for btrfs"), but as people
are doing more W=1 compile testing, it will start to show up elsewhere,
too.
