IA64 ATA patch.
We've had this in Fedora since 2007/02/27
Can anyone recall why? and more importantly, why it isn't upstream?

rawhide patches.
I just sifted through what we had in rawhide, after noticing that ls *.patch was starting to scroll my terminal (which is never a good sign). In doing so, I found a bunch of patches that weren't applied any more that we forgot to remove, and a bunch that were applied that shouldn't have been. Sifting through the remnants gave me a list that I've added to cvs as the file 'TODO' in devel. Hopefully we can keep this up to date as patches are introduced/removed. At the least it should serve as reasoning for why the hell we're carrying some patches for years (some of the CVS changelogs are pretty crappy, including some from yours truly).

The problem is this is a "who do we want to screw over" patch.

Re: de-modularising for the win!

I'm ok with all of these specific config changes, but I'd like to repeat what I said in Kyle's session about demodularising in general. I advocate extreme caution before just willy-nilly building everything into the kernel. Although this might seem like a great idea from the point of view of speeding up boot, there is also the pesky issue of users wanting the choice to decide which modules get loaded, and more importantly, wanting to override those modules with their own. To do this truly "right" we'll need to do rebinding of drivers in kernel. That's not always going to be easily possible after it's in use. And while we might not love binary drivers, note that it is the user's choice to make. If they want to load proprietary (or just out of tree drivers) then we should not go out of our way to intentionally make this difficult for them. i.e. let's no go building in particular graphics drivers for political reasons...I'm pre-empting discussion there :) So, anyway, Bill's got a good base set of common options.

chcorefilter
The /proc/PID/coredump_filter mechanism makes it easy to tweak the
per-process setting to control ELF core dump style details.
This setting is per-process (per-mm) and inherited by children.
But as a user, the /proc interface is insane. It prints a magical hex
value (without a leading 0x, to make it sneaky), which you'll be damn lucky
to figure out from reading Documentation/filesystems/proc.txt. Then you
get to set it to another such magical value, which is in decimal unless you
add a leading 0x (cat /proc/x/coredump_filter > /proc/y/coredump_filter
does not copy the setting, go team).
I have kicking around this half-assed bash script that I don't care to
bother making really presentable. Where should it live? In the upstream
kernel's scripts/? (Then noone would ever see it for sure.)
In util-linux-ng? Or what? Someone want to take it off my hands?
Thanks,
Roland
