[PATCH 0/2] fix build failure of mn10300

[Sudip Mukherjee]

Hi,
This is an attempt to fix the build failures when building mn10300 with
allmodconfig. It is still not completely fixed, but now atleast two
errors less than all the errors.

[PATCH 1/2] mn10300: fix build failure

[Sudip Mukherjee]

allmodconfig build fails with the error:
invalid use of undefined type 'struct kprobe_ctlblk'

just declared the two basic structures after checking the struct in other
architectures.

[PATCH 2/2] mn10300: Provide dummy dma_alloc_attrs() and dma_free_attrs()

[Sudip Mukherjee]

allmodconfig fails to build with following errors.

drivers/media/platform/sti/bdisp/bdisp-hw.c:
	In function 'bdisp_hw_free_nodes':
drivers/media/platform/sti/bdisp/bdisp-hw.c:132:3: error:
	implicit declaration of function 'dma_free_attrs'
	
drivers/media/platform/sti/bdisp/bdisp-hw.c:
	In function 'bdisp_hw_alloc_nodes':
drivers/media/platform/sti/bdisp/bdisp-hw.c:157:2: error:
	implicit declaration of function 'dma_alloc_attrs'

mn10300 does not provide those functions at this time.
Provide dummy implementations to avoid build errors.

please drop this series. I am sending v2 which completely fixes the
build failure.
