tile: work around bug in the generic sys_llseek
commit 5a114b98661e3aaa0ac085eb931584dce3b0ef9b upstream.
sys_llseek should specify the high and low 32-bit seek values as "unsigned
int" but instead it specifies "unsigned long". Since compat syscall
arguments are always sign-extended on tile, this means that a seek value
of 0xffffffff will be incorrectly interpreted as a value of -1ULL.
To avoid the risk of breaking binary compatibility on architectures
that already use sys_llseek this way, we follow the same path as MIPS
and provide a wrapper override.
