Sparc-2.6.24 GIT tree

Sparc-2.6.24 GIT tree

[David Miller]

I cut a 2.6.24 sparc development tree at:

	kernel.org:/pub/scm/linux/kernel/git/davem/sparc-2.6.24.git

merely because I wanted to dump some framebuffer driver changes
out of my inbox that were not appropriate for 2.6.23

The sparc32 asm-sparc/fcntl.h build fix isn't in there, but it's
easy for those interested to patch it in and it will show up there
next time I rebase.

I've been trying to upgrade the 2.6.20 kernel on a T1000 to a vanilla
2.6.22.1 kernel, but have so far failed to build a kernel that will boot
cleanly. (I used make oldconfig on the 2.6.20 .config + lots of minor
variations).

Will I have better luck if I follow one or more of your trees, David?
Which tree is best to follow? Could you give a quick overview of your
trees and how they fit in with upstream (or point me to an FAQ if there
is one).

Or, if 2.6.22.1 should boot fine on a T1000, perhaps someone could mail
me a known good .config that I could use as a base?

Thanks!

I use arch/sparc64/defconfig, enable CONFIG_FUSION* and CONFIG_SMP,
works fine on all my Niagara boxes.

BTW, please report this kind of failure as soon as you see
it, not 2 releases later which makes it infinitely harder to
track down the cause of the problem.

Thanks.

Do these warnings matter?

What compiler version do you use?

I've got a horrible feeling I've just spent a day fighting against a
miscompilation by gcc-4.2.

Perhaps this is a known problem? I'm rebuilding with gcc-4.1.2 now and
will report back shortly....
