libsysdecode; mktable fix vmresult table, enhance sigbuscode table

[bz]

Summary

The vmresult table was missing most of the values apart from two due to extra "_" in the names we grep for. Add the "_" to the pattern.

On x86 various BUS_* values were missing as they are in the machine specific header. Enhance the gen_table() function to take multiple files to grep through and enhance the pattern to grep for for BUS_*.

So this isn't actually correct. The values in <machine/trap.h> are stale (and should probably be removed). The MI values in <sys/signal.h> are what the the actual code in sys/amd64/amd64/trap.c uses. I will just cleanup the garbage values from sys/x86/include/trap.h to avoid future confusion.

This is ok.

Thanks for the feedback; I'll get the one-liner in and leave the rest of the cleanup to you.

I see, I was working on 3rd party code which still did use:

grep -c BUS_PAGE_FAULT ../amd64/amd64/trap.c

Hmm, even on HEAD seems that one is still used. I'll leave the cleanup to you then.
