Hi,
Thanks for testing. We probably need something like the following to
make sure we don't hit this on other arches. Steve - I will send 4
separate patches for this to get arch maintainers' acks for this?
Thanks,

What's the 4 byte alignment requirement from?
On 64-bit our JUMP_ENTRY_TYPE is 8 bytes, should we be aligning to 8
bytes?

Can you line those up vertically?

Otherwise that looks fine assuming 4 bytes is the correct alignment.

The 4 byte alignment is coming from this patch in linux-next:
https://lkml.org/lkml/2017/2/3/558
It reduces the size of 'struct static_key' by making use of the two
least significant bits of the static_key::entry pointer. Thus, the
jump_entry table needs to be 4 byte aligned to make it work. I added a
WARN_ON() to make sure the jump_entry table is in fact 4 byte aligned,
and that is what we hit here.

4 bytes should be sufficient and apparently fixes the WARN_ON() that was
hit.

I just got back from ELC, so sorry for the late reply.
I think you can just send this as one patch, as it is a single fix. Cc
each of the arch maintainers though. Unless you think it will have
conflicts with other changes in those archs. But I'm assuming there
wont be any conflicts.
This is a fix for something that I just pushed to Linus, thus it can
still get in after the merge window closes.
