MIPS supports a variable page size but glibc defines a constant. This causes at least two glibc tests to fail when the page size does not match the hard-coded size: inet/test-ifaddrs inet/test_ifindex [BZ #16191] * NEWS: Mention bug fix. * sysdeps/unix/sysv/linux/mips/sys/user.h (PAGE_SHIFT): Remove. (PAGE_SIZE, PAGE_MASK, NBPG, UPAGES): Likewise. (HOST_TEXT_START_ADDR, HOST_DATA_START_ADDR): Likewise. (HOST_STACK_END_ADDR): Likewise.
