New hppa kernel packages uploaded (3.10.11, aka 3.10-3) to parisc archives

[John David Anglin]

I have upload a new Debian kernel build (3.10.11) to the parisc archive:
deb http://ftp.parisc-linux.org/debian-ports/unstable  unstable main

Except for linux-image-3.10-3-parisc-smp, the packages have been boot
tested on c3750 and rp3440.

Enjoy,
Dave

To get devtmpfs you need a kernel built with CONFIG_DEVTMPFS.  I think  
the Debian kernels in the archive
have this.  However, at least some of the default parisc kernel  
configs miss this option.

What has changed is udev.  Previously, it didn't require devtempfs  
support.  Annoying, I know.

Do you want me to send udev deb for last version that worked without  
devtmpfs?

This isn't drive order issue.  I wrote a warning about this to list.   
It shouldn't be update until you have kernels
built with CONFIG_DEVTMPFS.

CC'd list.

You are correct.
I just tested shortly the 712_defconfig and c3000_defconfigs, and both are missing CONFIG_DEVTMPFS.

What about DEVTMPFS_MOUNT? Is it needed as well? 
(Automount devtmpfs at /dev, after the kernel mounted the rootfs (DEVTMPFS_MOUNT) [N/y/?] (NEW))

I think it makes sense to update the defconfigs.
What else do you know might be missing?

This only has an effect if no initrd is used. But it would help for the case it 
is not, and has no bad effect in case an initrd is used, so both should be 
switched on.
