The value it provides is orders of magnitude too large on modern systems. This patch replaces the formula with ACPI _PSS latency values for more accuracy and better performance. I've tested it on two 2nd generation Opteron systems, a 3rd generation Operton system, and a Turion X2 without seeing any stability problems.

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.

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.
