[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index] [PATCH] x86+Arm: drop (rename) __virt_to_maddr() / __maddr_to_virt()
There's no use of them anymore except in the definitions of the non- underscore-prefixed aliases. Rename the inline functions, adjust the virt_to_maddr() #define-e, and purge the (x86-only) maddr_to_virt() one, thus eliminating a bogus cast which would have allowed the passing of a pointer type variable into maddr_to_virt() to go silently.
