Subject: sh: Save NUMA node data in vmcore for crash dumps.
X-Git-Tag: v2.6.27-rc2~42^2~7
X-Git-Url: https://err.no/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=c3b4adfa65bae300a143188491e285556ca80fff;p=linux-2.6

sh: Save NUMA node data in vmcore for crash dumps.

Presently the NUMA node data isn't saved on kexec. This implements a
simple arch_crash_save_vmcoreinfo() for saving off the relevant data.
