Thank you for doing this work.

__sparc_v9__ means CONFIG_SPARC64, if that is not defined it's
CONFIG_SPARC32, so you could simplify this patch a lot.

1) Remove __sparc_v9__ ifdefs from asm-sparc64/fb.h
2) Define fb_mmap_required() to return 0 in asm-sparc64/fb.h
3) Define fb_mmap_required() to return 1 in asm-sparc/fb.h
4) Remove all the sparc ifdef stuff you added to linux/fb.h
5) There won't be a default fb_mmap_required() provided by
linux/fb.h on platforms other than sparc ones, you'll need
to provide one in order for the build to work non-sparc since
this call is unconditional in fbmem.c:

+ if (fb_mmap_required())
+ return -EINVAL;

With those fixes:
