Removed the PM: prefix. Everything else is same. So, I kept the v3 prefix as well. v3: And now v3 of this series. Basically a minor change wrt string manipulation. No need to use strlen in so many places. Previous log for reference: v2: Here is the version 2 of this series. Now die id is protected using same x86 protection mechanism to hide x86 product number. Besides, a compilation Kconfig option has been added for DIE ID as well. Here is previous PATCH 0/4 message: v1: This series is to continue what has been discussed several weeks ago wrt IDCODE patch. Original patch was made by Peter and discussion is here: http://www.mail-archive.com/linux-omap@vger.kernel.org/msg17553.html So, the conclusion was that IDCODE info is useful even in production systems, and for that debugfs is not a good choice to export it. One suggestion was to add it under /proc/cpuinfo. However this entry nowadays exports only ARM related information. So this series does the trick by extending the ARM /proc/cpuinfo to include soc info data. There are a few ways to add a hook for soc specific data. But I've decided to implement it via the simplest way I found. Basically it is same thing which is done for system_rev, system_serial_low and system_serial_high. Then, now we have system_soc_info, which is printed only if there is something useful there. As usual, comments are welcome.
