[PATCH] fix ia64 syscall auditing
Attached is a patch against David's audit.17 kernel that adds checks for the TIF_SYSCALL_AUDIT thread flag to the ia64 system call and signal handling code paths.The patch enables auditing of system calls set up via fsys_bubble_down, as well as ensuring that audit_syscall_exit() is called on return from sigreturn. Neglecting to check for TIF_SYSCALL_AUDIT at these points results in incorrect information in audit_context, causing frequent system panics when system call auditing is enabled on an ia64 system.
