[ Upstream commit c59ae0a1055127dd3828a88e111a0db59b254104 ]

clang warns:

arch/mips/mm/tlbex.c:634:19: error: use of logical '&&' with constant
operand [-Werror,-Wconstant-logical-operand]
        if (cpu_has_rixi && _PAGE_NO_EXEC) {

        if (cpu_has_rixi && _PAGE_NO_EXEC) {

warning
        if (cpu_has_rixi && _PAGE_NO_EXEC) {
                        ~^~~~~~~~~~~~~~~~
1 error generated.

Explicitly cast this value to a boolean so that clang understands we
intend for this to be a non-zero value.
