Everyone else has reported that
http://git.kernel.org/tip/055c47272b8f5679d08ccc57efea3cb4aaeb5fc6 fixes
the boot issue for them.

One problem with testing this patch was making sure you do a completely
clean build by removing the old build files through a 'make mrproper.'
So, after applying this patch do (after having copied your .config to a
safe place :))

make mrproper

and just to make sure no arch_hweight stuff is left, do

grep -EriIn 'x86.*hweight\.h' arch/um/

You shouldn't be getting any matches. If you do, than try to find out
why you do because all those intermediary *.o.cmd files shouldn't
contain any hweight-include files from arch/x86/.

At least the effects on b2c2-flexcop-pci are still valid, in linux-2.6
HEAD and linux-next (next-20100621).

Did not see this one for long long time, so it was probably fixed.

We have been knocking these off as they appear. There is one or two
that the relevant maintainers have been ignoring, but that always seems
to be the case. ;-)

Your choice as to whether you want to track the group...

I think I'll simply leave that one bug open until all known instances have been
dealt with.

Please let me know when that happens. :-)

So if I am sufficiently forgetful, I can just ask you to close the
bug immediately?

Sorry, but you really couldn't expect me to pass up that kind of

the second issue - UM is broken for CONFIG_SLAB still exists.
So I think we can keep the bug open.

Yes, the bug is still present in 2.6.34 and .35-rc3, but a tested patch is
available, hopefully to be included in 2.6.35.
