3.13.11-ckt18 -stable review patch.  If anyone has any objections, please let me know.


From: Jay Lan <jlan at sgi.com>

commit 146755923262037fc4c54abc28c04b1103f3cc51 upstream.

The output of KDB 'summary' command should report MemTotal, MemFree
and Buffers output in kB. Current codes report in unit of pages.

A define of K(x) as
is defined in the code, but not used.

This patch would apply the define to convert the values to kB.
Please include me on Cc on replies. I do not subscribe to linux-kernel.
