I have implemented a low-overhead method for detecting interrupt storm in softlockup. Please review it, all comments are welcome.
Changes from v1 to v2:
- From Douglas, optimize the memory of cpustats. With the maximum number of CPUs, that's now this. 2 * 8192 * 4 + 1 * 8192 * 5 * 4 + 1 * 8192 = 237,568 bytes.
- From Liu Song, refactor the code format and add necessary comments.
- From Douglas, use interrupt counts instead of interrupt time to determine the cause of softlockup.
- Remove the cmdline parameter added in PATCHv1.
