Log:
mips: improve recognition of different MIPS processors
Recognize correctly MIPS processors. Previously, for some of the cpu models,
Valgrind would incorrectly assume it is a regular MIPS model, as it would
find word MIPS in /proc/cpuinfo that came from "BogoMIPS" label.

hi all:
I have some questions about massif:
1. from massif.out file, I cannot tell where the free is called
I compile the sample code in the document page as below and get
the massif output. From the log, there are messages about where
"malloc" is called, but I cannot find the place for "free".
is there any option I need to add when using massif tool or config
I need to add when compile the valgrind?
( in the smple I attach, the line#28 is where "free" is called, but
there is no such information in the massif output)
2. there is a option call "--trace-children=yes" to capture all
children information.
is it possible to limit the specific child name for tracking?
if possile, should I use some other valgrind execution options or
modify the source code?
appreciate all your kind help in advance,
