The deprecation patch was on LKMl (I don't remember whether I sent it to linux-arch), but there were a bunch of related patches to clean out the old irq related cruft which were sent to linux-arch and also hit the parisc tree.

CONFIG_ENABLE_WARN_DEPRECATED=y perhaps ? I'm really tired of your whining when you did not get a personalized taylored to your needs info. 14 architectures got converted and some maintainers sent out mail to their users 18 month ago right after the deprecation patch was sent (www.linux-mips.org/archives/linux-mips/2009-03/msg00068.html), there were reviews of new architecture code on linux-arch where this was pointed out, so don't tell me that there was not enough information about this. > > Either that or moving everything what breaks into staging/arch/* and > > hand it over to GregKH :) > > > > Thoughts ? > > We could move x86 into staging while it tries out the replacement ... The replacement of what?
