When bootgraph.pl parses a file, it gives one row for each initcall's pid. But only few of them will be displayed => the longest. This patch corrects it by giving only a rows for pids which have initcalls that will be displayed.

The regexp used to match the start and the end of an initcall are matching only on [a-zA-Z\_]. This rules out initcalls with a number in them. This patch is fixing that. Signed-off-by: NArnaud Patard <apatard@mandriva.com> Signed-off-by: NIngo Molnar <mingo@elte.hu>

David Sanders reported some issues with bootgraph.pl's display of his sytems bootup; this commit fixes these by scaling the graph not from 0 - end time but from the first initcall to the end time; the minimum display size etc also now need to scale with this, as does the axis display.

When optimizing the kernel boot time, it's very valuable to visualize what is going on at which time. In addition, with the fastboot asynchronous initcall level, it's very valuable to see which initcall gets run where and when. This patch adds a script to turn a dmesg into a SVG graph (that can be shown with tools such as InkScape, Gimp or Firefox) and a small change to the initcall code to print the PID of the thread calling the initcall (so that the script can work out the parallelism).
