Hi all,
Changes since 20150129:
The arm-soc gained conflicts against the arm-current and arm trees.
The spi tree gained a build failure for which I reverted a commit.
Non-merge commits (relative to Linus' tree): 6300 6348 files changed, 255117 insertions(+), 131620 deletions(-)
Build failures below. I copied the culprits (including Linus ;-).

=== Building arc:defconfig ... failed Building arc:tb10x_defconfig ... failed
Error log: arch/arc/mm/fault.c: In function 'do_page_fault': arch/arc/mm/fault.c:164: error: 'VM_FAULT_SIGSEV' undeclared
Typo. Caused by 33692f27597f ("vm: add VM_FAULT_SIGSEGV handling support"), from mainline. I submitted a patch.
=== Building mips:allmodconfig ... failed
Error log:
fs/built-in.o: In function `dax_fault': (.text+0x5e284): undefined reference to `copy_user_page'
Caused by 4927b7d77c001 ("dax,ext2: replace the XIP page fault handler with the DAX page fault handler"). Looks like copy_user_page does not exist in mips.
=== Building sparc64:allmodconfig ... failed
Error log: drivers/built-in.o: In function `asm9260_timer_init': asm9260_timer.c:(.init.text+0x60d4): undefined reference to `of_io_request_and_map'
Caused by e4940cd76934 ("ARM: clocksource: add asm9260_timer driver"). of_io_request_and_map does not exist for the sparc architecture. Maybe that driver should depend on ARM or at least on !SPARC ?
=== Building xtensa:allmodconfig ... failed
Error log: drivers/gpu/drm/drm_gem_cma_helper.c: In function ‘drm_gem_cma_create’: drivers/gpu/drm/drm_gem_cma_helper.c:110:2: error: implicit declaration of function ‘dma_alloc_writecombine’ drivers/gpu/drm/drm_gem_cma_helper.c: In function ‘drm_gem_cma_free_object’: drivers/gpu/drm/drm_gem_cma_helper.c:193:3: error: implicit declaration of function ‘dma_free_writecombine’ drivers/gpu/drm/drm_gem_cma_helper.c: In function ‘drm_gem_cma_mmap_obj’: drivers/gpu/drm/drm_gem_cma_helper.c:330:2: error: implicit declaration of function ‘dma_mmap_writecombine’
Caused by 1a396789f65a2 ("drm: add Atmel HLCDC Display Controller support"). It selects DRM_KMS_CMA_HELPER which selects DRM_GEM_CMA_HELPER which needs the missing dma functions. Those are not supported on xtensa (HAVE_DMA_ATTRS is not set for xtensa). Maybe the controller should depend on HAVE_DMA_ATTRS.
I fixed that one a week ago: [1]. I'm Adding Dave and the dri-devel ML in Cc, apart from that I don't know what I can/should do to make it appear in linux-next.
Dave, unless you think there is a risk in applying this patch, could you take it in your drm-next tree ?
Best Regards,
Boris
