Subject: [PATCH][Resend] PCI Express ASPM support should default to 'No'

From: Jesper Juhl <jesper.juhl@...il.com>

Andrew; if you could merge this in -mm it would be good, otherwise I'll 
just queue it up in the trivial tree for the next merge window.


Running 'make oldconfig' I just noticed that PCIEASPM defaults to 
'y' in Kconfig even though the feature is experimental and the 
help text recommends that if you are unsure you say 'n'.
It seems to me that this really should default to 'n', not 'y'.
The following patch makes that change. Please consider merging.

Jesse Barnes commented on the patch that it "Seem reasonable".
Shaohua Li also commented saying "Ok, I'm fine with the patch."
