[PATCH 0/9] arm-soc/for-next allyesconfig build regressions

[Arnd Bergmann]

These are the patches I still need to cleanly build allyesconfig
and allmodconfig on arm-soc/for-next. Please review and provide
Acks where appropriate so we can add the fixes directly to the
branches that introduce the problems, or apply them directly
to a maintainer tree where appropriate.

The bulk of these patches happen to be omap specific, which
does not mean that we had a lot of regressions in omap, but
that we just started including omap in the multiplatform
builds, which has uncovered a number of older problems that
we did not see before.

[PATCH 6/9] net: cwdavinci_cpdma: export symbols for cpsw

[Arnd Bergmann]

With the support for ARM AM33xx in multiplatform kernels
in 3.9, an older bug appears in ARM allmodconfig:
When the cpsw driver is built as a module with cpdma
support enabled, it uses symbols that the cpdma driver
does not export.

Without this patch, building allmodconfig results in:

ERROR: "cpdma_ctlr_int_ctrl" [drivers/net/ethernet/ti/ti_cpsw.ko] undefined!
ERROR: "cpdma_control_set" [drivers/net/ethernet/ti/ti_cpsw.ko] undefined!
ERROR: "cpdma_ctlr_eoi" [drivers/net/ethernet/ti/ti_cpsw.ko] undefined!
