/*
* modemlog
*
* Usage: /system/bin/modemlog [filename]
*
* Grabs BP panic data from: /proc/last_kmsg and /proc/kmsg or a log file
* given on the command line BP panic data is stuck into
* /data/panicreports. AP panic data is stuck into /data/kernelpanics.

* when who what, where, why
* ----------------------------------------------------------------------
* Feb 25th, 2010 Liu Peng-a22543 report watchdog reset as a special kernel panic
* Jan 25th, 2010 Liu Peng-a22543 Only keep useful kernel panic logs
* Jan 18rd, 2010 Mao Weiyang-A22957 Rename kernel panic logs
* from ap_XXXX to ap_kernel_panic_XXXX
* Rename watchdog reset logs
* from bp_XXXX to wdog_ap_reset_boot_info_XXXX
* Oct 30th, 2009 Liu Peng-A22543 Moving modemlog to MAP3
* 7/10/2009 qcf001 bug11379: Not logging Power-cuts to panicreports.
* They are uninteresting.
* 5/6/09 bfp468 Logging hardware watchdog and power cut as panics in
* /data/panicreports/.
* 5/1/09 jwnd84 Added linux kernel panics again.
* Don't know what happened to my previous mod; git must have eaten it.
* 2/12/09 jwnd84 Created this program for cutting out modem panic data
* and managing panic dump size.
