[PATCH] Xen i386 xen-head.S fix sections mixup
...leaving the text section as current section. It causes problems with a slightly enhanced DEBUG_RODATA that supports CONFIG_HOTPLUG and bringing a CPU up after the text has been marked read-only: reference to early_gdt_descr causes a page fault. It applies on 2.6.22-rc2-mm2.

(marginal) dot diagram
...ins along both the X and Y axes. I have looked everywhere I can think for information. Can anyone give me any suggestions? Is there a single command that generates it or do I have to generate a regular scatterplot then add the additional plots in the margins? Thanks in advance for your help. Neil Desnoyers

Barchart questions
...is that it's the "proper extent of the bar". Is that the maximum value? Or is it the labels for my vertical axis, since the axes seem to be switched for this command? Is there a better/different command I should be using for barcharts (i.e. barplot)? Thanks for your assistance. Neil Desnoyers
