Hello,

This is the 5th version of the series for the boot-time tracing.

Previous version is here.

Hi Masami,

I applied all your patches to a test branch and was playing with it a
little. This seems fine to me and works well (and very easy to use).
Probably could use some more examples, but that's just a nit.

If nobody has any issues with this code, I'll wait for v6 with the
fixes to issues found in this series, and I'll happily apply them for
linux-next.

In this version, I removed RFC tag from the series.
Changes from the v4 are here, updating bootconfig things.

 - [1/22] Fix help comment and indent of Kconfig.
          Restrict available characters in values(*)
          Drop backslash escape from quoted value(**)
 - [3/22] Fix Makefile to compile tool correctly
          Remove unused pattern from Makefile
 - [4/22] Show test target bootconfig
          Add printable value testcases
          Add bad array testcase
 - [9/22] Fix TOC list
          Add notes about available characters.
          Fix to use correct quotes (``) for .rst.

(*) this is for preventing admin from shoot himself.
(**) this rule is from legacy command line.

Boot-time tracing features are not modified. I know Tom is working
on exporting synthetic event (and dynamic events) APIs for module.
If that APIs are merged first, I will update my series on top
of that.

This series can be applied on v5.5-rc3 or directly available at;
