When returning from the user probe code into userspace process, PC & NPC are truncated to 32 bits. Due to shared libraries getting loaded very high in the virtual address space of the process, placing a user probe inside a shared library makes the kernel return into the process at the wrong address, causing it to seg'fault most of the time. This patch prevents truncating PC and NPC. Signed-off-by: Eric Saint Etienne <eric.saint.etienne@oracle.com> Reviewed-by: David Aldridge <david.j.aldridge@oracle.com> Signed-off-by: David S.
