Here are a few trivial fixes to arch/metag/. All except the first patch
depend on stuff in -next. Except arch/metag, only the last patch depends
on something not yet in mainline.
James Hogan (5):
metag: Provide dma_get_sgtable()
metag: remove GENERIC_SIGALTSTACK
metag: remove select
/dma-mapping-common.h.
Metag does not use dma_map_ops yet, hence it should implement it as an
inline stub using dma_common_get_sgtable().

Since commit irq_work: Remove CONFIG_HAVE_IRQ_WORK the Kconfig symbol
HAVE_IRQ_WORK has gone. Remove the select from METAG too.

The commit burying unused conditionals removed among other things the
CONFIG_GENERIC_SIGALTSTACK Kconfig symbol as it's selected by every
architecture. Therefore remove the select from CONFIG_METAG too.

Here is the arch/metag/ tree for v3.9-rc1. Arnd said he's happy to ack
it (the additional changes since then have been mostly further cleanups
and fixes for when merged with other trees).
Please pull.
I'd just
dma_get_sgtable() as added recently for other arches
* remove CONFIG_GENERIC_SIGALTSTACK
* remove CONFIG_HAVE_IRQ_WORK
* remove CONFIG_EXPERIMENTAL from defconfigs
* remove SET_PERSONALITY()

I think it would be better to have INIT_LIST_HEAD() during @entry
initialization
