2009-02-06x86-64: fix int $0x80 -ENOSYS returnRoland McGrath
One of my past fixes to this code introduced a different new bug. When using 32-bit "int $0x80" entry for a bogus syscall number, the return value is not correctly set to -ENOSYS. This only happens when neither syscall-audit nor syscall tracing is enabled (i.e., never seen if auditd ever started). Test program: /* gcc -o int80-badsys -m32 -g int80-badsys.c Run on x86-64 kernel. Note to reproduce the bug you need auditd never to have started. */ #include <errno.h> #include <stdio.h> int main (void) { long res; asm ("int $0x80" : "=a" (res) : "0" (99999)); printf ("bad syscall returns %ld\n", res); return res != -ENOSYS; } The fix makes the int $0x80 path match the sysenter and syscall paths.

2009-02-04Blackfin arch: Remove outdated codeMichael Hennerich
The removed version with the loop registers saved on the stack was originally intended to workaround the missing toolchain support for LoopReg Clobbers. Since our toolchain now supports these there is no point in keeping this workaround. And since we don't touch LoopRegs anymore we're no longer subject for ANOMALY_05000312.
