Subject: mips maltaup_xpa_defconfig build failure with clang

Message-ID: <YulSY1pDms0ZyNs9@debian> (raw)
Hi All,
Not sure if it has been reported, mips maltaup_xpa_defconfig fails to
build with clang with the error:
arch/mips/mm/tlbex.c:629:24: error: converting the result of '<<' to a boolean; did you mean '(1 << _PAGE_NO_EXEC_SHIFT) != 0'? [-Werror,-Wint-in-bool-context]
if (cpu_has_rixi && !!_PAGE_NO_EXEC) {
^
./arch/mips/include/asm/pgtable-bits.h:174:28: note: expanded from macro '_PAGE_NO_EXEC'
# define _PAGE_NO_EXEC (1 << _PAGE_NO_EXEC_SHIFT)
^

if (!cpu_has_rixi || !_PAGE_NO_EXEC) {
