I am seeing similar problem on V480, with kernel crosscompiled from
server with gcc (and other up to date userland from Debian sparc64).
Sometimes it happesn after I change a configuration option (like rmeove
cassini from being built in) and does not go away when I change the
option back.

If someone can bisect this it would help tremendously.
I've been away from my sparc64 systems for a while and I hope I can get
started working on these regressions again soon.

tried with debian sparc64 default kernel config file, and git kernel
v4.15-rc1-24-g43570f0383d6
still this LDOM doesn't boot. Kernel boot log is below.
Going to try git://git.kernel.org/pub/scm/linux/kernel/git/davem/sparc.git
to boot and bisect...

And we're suddenly crashing in completely unrelated IPSEC networking
code.
Something is seriously wrong here.

We are initializing free memory, then we end up at a totally unrelated
piece of code.
Something is causing the cpu to call some random address and we need
to figure out why.
I've built the current kernel on a SunBlade-2500 with gcc-4.4.5 and I
couldn't reproduce this crash.

Do you have a spare partition, or extra free disk, for use? Sparc64 is
what some of us are running. Maybe it helps reproducing. ;-)

That's nice, but this appears to be a Niagara and later specific problem
which is why I can't reproduce it.

Thanks for bisecting, I'll take a look.

The problem is that the distance between the generic sparc64 fls/__fls
symbols and the NG4 optimized ones are too large for the branch patch.
It needs to fit in a 19-bit displacement field.
When there are library routines and patching, you have to group them
near eachother. This means if the generic routine is "lib-y" you
have to make the patch code "lib-y" too.
In this case, the NG4fls.o object is placed into "obj-y" which is
too far from the "lib-y" code to fit into the disp19 relocation
of the patch branch.
Vijay, why did you put the NG4fls.o into obj-y?
Anatoly, please try this patch:

Thanks, I'll push this upstream.

You are right, obj-y is not required.
Thanks,
