* config/mips/tm-linux.h (REALTIME_LO, REALTIME_HI): Define
conditionally. (JB_PC, JB_ELEMENT_SIZE): Rename to MIPS_LINUX_JB_PC and MIPS_LINUX_JB_ELEMENT_SIZE. * mips-linux-tdep.c (supply_gregset, fill_gregset): Use alloca for MAX_REGISTER_RAW_SIZE arrays. (mips_linux_get_longjmp_target): Use MIPS_LINUX_JB_PC and MIPS_LINUX_JB_ELEMENT_SIZE.
