Hello!
After kernel 4.7.2 entered Debian unstable, I decided to upgrade the buildds and ran into an
apparent regression with the 4.7.x kernels on sun4u machines:

Just reverting the kernel version to 4.6.4 fixes the problem. Attaching the full log.

reproduced with latest git 4.9.0-rc1+ (v4.9-rc1-148-g6f33d645) kernel.
Machine boots ok, i can login as unprivileged user (via ssh), compile
and install kernel, run sudo, install packages (apt upgrade),
apache/mysql and other startup daemons works, but if I try to login as
root via ssh, it throws kernel oops / illegal instruction.
Any idea how to debug this?
otherhost$ ssh ttip -l root -v

In the instruction dump, the offending instruction is always 3ffffff2,
and according the the opcode map, this is some kind of Fujitsu Athena
instruction which probably ought to never be generated by gcc. Can you
check to see if this instruction is in your vmlinux file? Do 'objdump -d
vmlinux' and go to the addresses shown in TPC in the dump (ie,
00000000005ccfe) and see what's there. If you see 3ffffff2, then somehow
some bogus instruction made it into the vmlinux executable. If you see
something else, then it means that the instruction got changed in memory
after the system was booted. That could be either a stray memory write
or a boot time patch gone wrong. Either way, it may help narrow down the
problem.

Hi Rob,
They are definitely NOPs in vmlinux being clobbered at load/runtime. According
to "gdb vmlinux", the call to _cond_resched is coming from mm/slab.h
slab_pre_alloc_hook (the call to might_sleep_if). What's the best way to get a
backtrace for writes to this address?

James

It could be that we need to use non-predicting branches in the jump
label implementation. We could be overflowing the branch displacement
range if the kernel being built is really huge.
Something like the following would fix it if true:
diff --git a/arch/sparc/kernel/jump_label.c b/arch/sparc/kernel/jump_label.c

Yes, I found that. I don't think its overflowing, more negative (hence the 3ffffff2, which would be fffff88 or something like that for off). Trying with that masked appropriately. If it works I'll send a patch with appropriate BUG_ONs.

This indeed was the case. The attached patch fixes the problem for me,
generating 0x106ffff2, which gdb can verify is sensible (of course, the
addresses have shifted slightly):
(gdb) x/10xw 0x5c9880
0x5c9880: 0x400f10d0 0x01000000 0x106ffff2 0x01000000
0x5c9890: 0x106fffc8 0x01000000 0xc611a036 0x05002c36
0x5c98a0: 0x8410a038 0x8328f030
(gdb) x/i 0x5c9888
0x5c9888: b %xcc, 0x5c9850
0x5c988c: nop
I also took the opportunity to correct the misleading/incorrect comments.
Please let me know if you’d like this properly submitted git-send-email style.
Regards,
James

Please don't use attachments for patch submissions.
Patches must be inline so that they can be commented upon properly
using simply email quoting mechanisms.
Thank you.

Since we can determine at run time whether we need to use a non-v9
branch or not, it makes no sense to fail when a v9 branch is out of
range.
We can simply downgrade to a pre-v9 one.
Something like this:
