423bec4307 Documentation: correct overcommit caveat in hugetlbpage.txt
As shown by Gurudas Pai recently, we can put hugepages into the surplus
state (by echo 0 > /proc/sys/vm/nr_hugepages), even when
/proc/sys/vm/nr_overcommit_hugepages is 0. This is actually correct, to
allow the original goal (shrink the static pool to 0) to succeed (we are
converting hugepages to surplus because they are in use). However, the
documentation does not accurately reflect this case. Update it.

d5dbac87b4 Documentation: update hugetlb information
The hugetlb documentation has gotten a bit out of sync with the current code.
Updated the sysctl file to refer to Documentation/vm/hugetlbpage.txt.  Update
that file to contain the current state of affairs (with the newer named sysctl
in place).

5e12227179 [PATCH] Doc: vm/hugetlbpage update-2
Add new line of /proc/meminfo output.

Explain the HugePage_ lines in /proc/meminfo (from Bill Irwin).

Change KB to kB since the latter is what is used in the kernel.

5c7ad5104d [PATCH] perform maintenance on Documentation/vm/hugetlbpage.txt
Updates to Documentation/vm/hugetlbpage.txt:

- there's no need to select HUGETLB_PAGE manually and it's no longer
  under the processor menu.  Update the text accordingly.

- fix typos and trim trailing whitespace.

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.

Let it rip!
