[patch 006/100] MIPS: Compat: Zero upper 32-bit of offset_high and offset_low.

[Chris Wright]

-stable review patch.  If anyone has any objections, please let us know.
---------------------

From: Ralf Baechle <ralf@xxxxxxxxxxxxxx>

upstream commit: d6c178e9694e7e0c7ffe0289cf4389a498cac735

Through sys_llseek() arguably should do exactly that it doesn't which
means llseek(2) will fail for o32 processes if offset_low has bit 31 set.

As suggested by Heiko Carstens.
