Hi Greg,
It seems we're down to a single warning on ARM and ARM64 now, and
the fix just got merged as commit
842775f15090 ("xen/balloon: Fix declared-but-not-defined warning")
so we can for the first time have a stable kernel that builds
without warnings on these architectures, nice!
On 4.7-rc, there are currently two warnings:
> fs/reiserfs/ibalance.c:1156:2: warning: 'new_insert_key' may be
> used uninitialized in this function [-Wmaybe-uninitialized]
> drivers/staging/iio/adc/ad7606_spi.c:24:18: warning: 'data' may be

The first one is an old issue that gcc recently started warning for,
a workaround (reiserfs: fix "new_insert_key may be used uninitialized
...") is currently in Andrew's akpm-current, but I think it's not
planned for 4.7 since it's not a regression and the code works
correctly.
The second one is a real bug, and the fix is now in the staging-linus
tree.
