MIPS: tlbex: Explicitly cast _PAGE_NO_EXEC to a boolean
[ 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) {
^ ~~~~~~~~~~~~~
arch/mips/mm/tlbex.c:634:19: note: use '&' for a bitwise operation
if (cpu_has_rixi && _PAGE_NO_EXEC) {
^~
&
arch/mips/mm/tlbex.c:634:19: note: remove constant to silence this
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.
