On NOMMU ARM, the __addr_ok() and __range_ok() macros do not evaluate
their arguments, which may lead to harmless build warnings in some
code where the variables are not used otherwise. Adding a cast to void
gets rid of the warning and does not make any semantic changes.

Without this patch, building at91x40_defconfig results in:

fs/read_write.c: In function 'rw_copy_check_uvector':
fs/read_write.c:684:9: warning: unused variable 'buf' [-Wunused-variable]

Thanks!

I can pick it up and push to the arm-soc tree.

Well, my idea was that I would prefer the patches go through some other tree
besides arm-soc since they are not really the main purpose for this tree.

The core ARM patches in particular should go through Russell's ARM tree.
I have a few more that come in during the merge window and plan to send
him a pull request for those.
