Description of Problem: If a corruption occurs that results in the kernel executing data (outside normal kernel code), the show_regs() function displays: EIP is at Using_Versions [] 0x40401234 Where 0x40401234 is one less than the unhandled kernel page fault address. How Reproducible: Completely Steps to Reproduce: 1. Corrupt the process table (This is the hard part...) 2. Collect the Oops. 3. Actual Results: EIP is at Using_Versions [] 0x40401234 Expected Results: EIP is at [unresolved] Additional Information: One idea would be to change the value of Using_Versions in kernel/ksyms.c to something like '0xf0000001' so that it sorts numerically after kernel code. However that's very 32-bit and probably not cross-platform portable. Perhaps the lookup_symbol in kernel/kksymoops.c or the functions in kernel/kallsyms.c should be made to avoid the __ksymtab section?
