2.6.32-longterm review patch. If anyone has any objections, please let me know.
------------------
From: Willy Tarreau <w@1wt.eu>
Initial stable commit : 2215d91091c465fd58da7814d1c10e09ac2d8307
This patch backported into 2.6.32.55 is enabled when CONFIG_AMD_NB is set, but this config option does not exist in 2.6.32, it was called CONFIG_K8_NB, so the fix was never applied. Some other changes were needed to make it work. first, the correct include file name was asm/k8.h and not asm/amd_nb.h, and second, amd_get_mmconfig_range() is needed and was merged by previous patch.
Thanks to Jiri Slabi who reported the issue and diagnosed all the dependencies.
