Question about /proc/acpi (Debian 7.2 w/ 3.2.0-4-686-pae kernel)

Hi everyone,
I am running Debian Wheezy 7.2 with a 3.2.0-4-686-pae kernel. There are a couple of virtual files and directories in /proc I can't seem to find much information about. I am aware that some of them might be legacy, though. Anyway, here they are:
  1. acpi: according to this link, this has been deprecated (if so, what has it been replaced with?), but it's still showing up in a pretty new system with a relatively new kernel.
  2. buddyinfo: this link offers a pretty good explanation, whereas this other link states that this file is used primarily for diagnosing memory fragmentation issues but does not explain how to detect an issue and / or correct it.
Actually there is a bunch of other files / directories, of which I presume the most important ones are:
  • cpuinfo
  • filesystems
  • interrupts
  • iomem
  • ioports
  • modules
  • pagetypeinfo
  • uptime
  • tty
In your opinion, am I missing anything?
As a final note, this is in preparation for Exam 101 of LPIC-1.
Any hints or suggestions will be more than welcome.
Thanks in advance.
