As an FYI, I'm attaching the Perl script Alan is referring to. [bergner@otta ~]$ ./scan-476-icache-bug.v5.pl -h Usage: scan-476-icache-bug.v5.pl [-h][-f][-v][-z][-s pagesize][directory|file ...] -h : Print help text. -f : Ignore some false positives (safe instruction followed by '.long 0x0's). -s N : Use page size of N (N must be a multiple of 4096). -v : Verbose mode.
