Subject: Fix warnings in MIPS build
This patch fixes the rest of the set-but-not-used warnings in the MIPS
code by using attribute_unused and also fixes some conversion warnings
by changing __arch_compare_and_exchange_xxx_[8|16]_int. Assigning __cmp
(int type) to __prev (pointer type) generates a warning. Assigning zero
to each separately avoids this warning without having to add a cast.
