> The kexec/kdump patch in my test tree is very stale, plus it is time

> "Auto-update from upstream" commits that my workflow generates). So
> I'm planning on resetting my "test" branch to Linus-latest + kdump/kexec
> (so git pull/fetch will barf on my test tree, you'll need to re-clone).

> 1) Take 2.6.18
> 2) Apply Nan Hai patch for 2.6.18 (posted Sept 20th)
> 3) Pull in Linus-latest (c972398b ...) and resolve conflicts in smp.h, sysctl.h
> 4) Apply Nan hai's "Fix OS_INIT" patch that fixed Indou-san's deadlock issue
> +(Sept 28th)
> 5) Fix a few warnings:
