[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.

......@@ -32,7 +32,16 @@ The output of "cat /proc/meminfo" will have lines like:
HugePages_Total: xxx
HugePages_Free: yyy
Hugepagesize: zzz KB
HugePages_Rsvd: www
Hugepagesize: zzz kB
HugePages_Total is the size of the pool of hugepages.
HugePages_Free is the number of hugepages in the pool that are not yet
HugePages_Rsvd is short for "reserved," and is the number of hugepages
for which a commitment to allocate from the pool has been made, but no
allocation has yet been made. It's vaguely analogous to overcommit.
/proc/filesystems should also show a filesystem of type "hugetlbfs" configured
in the kernel.
