Subject: [PATCH 04/14] arch/tile: change lower bound on syscall error return to -4095

Previously we were using -1023, which is fine for normal syscall
error returns, but the common value in use for other platforms
is -4095, and one Tilera-specific driver does use values in the
-1100 range, so tickled this bug.
