From ef18272453c97238fc9a89211d4c609ef9c760dc Mon Sep 17 00:00:00 2001 From: Simon Marchi Date: Sat, 22 Dec 2012 00:21:10 -0500 Subject: arch/tile: Call tracehook_report_syscall_{entry,exit} in syscall trace Call tracehook functions for syscall tracing. The check for TIF_SYSCALL_TRACE was removed, because the same check is done right before in the assembly file.
