Subject: [PATCH] xlat: use unsgined type for mount_flags fallback values
Reported by cppcheck:
strace/xlat/mount_flags.h:256: error[shiftTooManyBitsSigned]:
Shifting signed 32-bit value by 31 bits is undefined behaviour
# 254| XLAT(MS_BORN),
# 255| XLAT(MS_ACTIVE),
# 256|-> XLAT(MS_NOUSER),
# 257| XLAT_END
# 258| };
* xlat/mount_flags.in: Use 1U instead of 1 as a bit shifting operand.
