Jiri Kosina 16f3e95b32 cross-arch: don't corrupt personality flags upon exec() ... Historically, the top three bytes of personality have been used for things such as ADDR_NO_RANDOMIZE, which made sense only for specific architectures. We now however have a flag there that is general no matter the architecture (UNAME26); generally we have to be careful to preserve the personality flags across exec(). This patch tries to fix all architectures that forcefully overwrite personality flags during exec() (ppc32 and s390 have been fixed recently by commits f9783ec862 ("[S390] Do not clobber personality flags on exec") and 59e4c3a2fe ("powerpc/32: Don't clobber personality flags on exec") in a similar way already).
