tile: fix bug in get_user() for 4-byte values The definition of 32-bit values in the 64-bit tilegx architecture is that they should be sign-extended regardless of whether they are considered signed or unsigned by the compiler. Accordingly, we need to use an "ld4s" rather than "ld4u" to load and sign-extend for get_user(). This fixes glibc bug 14238 (see http://sourceware.org/bugzilla), introduced during the 3.5 merge window. Signed-off-by: Chris Metcalf <cmetcalf@tilera.com>
