Revision 607a16858397829806c5a4db999ce6daf327f98c authored by Andi Kleen on 20 May 2005, 21:27:58 UTC, committed by Linus Torvalds on 20 May 2005, 22:48:21 UTC
The test case at http://cvs.sourceforge.net/viewcvs.py/posixtest/posixtestsuite/conforman ce/interfaces/clock_nanosleep/1-5.c fails if it runs as a 32bit process on x86_86 machines. The root cause is the sub 32bit process fails to restart the syscall after it is interrupted by a signal. The syscall number of sys_restart_syscall in table sys_call_table is __NR_restart_syscall (219) while it's __NR_ia32_restart_syscall (0) in ia32_sys_call_table. When regs->rax==(unsigned long)-ERESTART_RESTARTBLOCK, function do_signal doesn't distinguish if the process is 64bit or 32bit, and always sets restart syscall number as __NR_restart_syscall (219).
