[IA64] preserve personality flag bits across exec
In its <asm/elf.h> ia64 defines SET_PERSONALITY in a way that unconditionally sets the personality of the current process to PER_LINUX, losing any flag bits from the upper 3 bytes of current->personality. This is wrong. Those bits are intended to be inherited across exec (other code takes care of ensuring that security sensitive bits like ADDR_NO_RANDOMIZE are not passed to unsuspecting setuid/setgid applications).
