Patch split out from:
https://sourceware.org/ml/libc-ports/2013-12/msg00017.html
Pre-approved by Joseph.
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.
