[Hotplug_sig] 2.6.12-rc3-mhp1

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hello,

I have set this up to be pulled into PLM automatically when you 
release.  This way you can see the compile results on multiple 
architectures.  Here is the current one:

   http://www.osdl.org/plm-cgi/plm?module=patch_info&patch_id=4410

Some of the architectures now do 'allmodconfig' rather than 'defconfig', 
so the hotplug options should get compiled.  These are ppc64, ppc40x, 
x86_64, and ia64.  The 'compregress' for ia32 has always done an
'allmodconfig' and 'allyesconfig' as well.
