Re: Scan-before-execute code for FreeMWare

[Kevin P. Lawton]

I enhanced the code so that additional info is kept WRT
each physical page; time stamps, cpl, seg-size, and
associated meta/modified pages etc.

I borrowed an inline fuction from the Linux kernel
to grab the Time Stamp Counter, and now time stamp
when the first time the prescan code sees a code
page, and when it last modified the meta information.

Ultimately, we can timestamp when the code is
last put into execution, and when a given virtualized
code page was last read and written to (since we'll
trap on those).

The command line args are still the same, as is
the algorithm itself.  Any test cases you write
are still good.  I'd like to hear of any conditions
I blew it for.  Will release another tarball after
I play with a few more things...
