Hi Krzysztof, Today's linux-next merge of the samsung-krzk tree got a conflict in: arch/arm/mach-exynos/Kconfig between commit: 4965a68780c5 ("arch: define the ARCH_DMA_ADDR_T_64BIT config symbol in lib/Kconfig") from the dma-mapping tree and commit: c5deb598089c ("ARM: exynos: Remove support for Exynos5440") from the samsung-krzk tree. I fixed it up (the latter removed the whole section modified by the former, so I just removed the section) and can carry the fix as necessary. This is now fixed as far as linux-next is concerned, but any non trivial conflicts should be mentioned to your upstream maintainer when your tree is submitted for merging. You may also want to consider cooperating with the maintainer of the conflicting tree to minimise any particularly complex conflicts. -- Cheers, Stephen Rothwell
