Hi all,

As of clang 9.0.0 at r366299 [1], we can build a QEMU bootable
malta_defconfig kernel with the following fixes (mostly due to -Werror)
and Nick's patch [2]. This has helped catch some potentially dubious
behavior with -Wuninitialized, which is stronger than GCC's
-Wmaybe-uninitialized.

If there are any comments or concerns, please let me know.

Cheers,
Nathan
