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 used uninitialized in this function [-Wmaybe-uninitialized]

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.
