You don't need to write a patch that replaces CONFIG_DMA_SHARED_BUFFER by 0. you can patch, instead, v4l/scripts/make_kconfig.pl, like those: # Kernel < 2.6.22 is missing the HAS_IOMEM option if (!defined $kernopts{HAS_IOMEM} && cmp_ver($kernver, '2.6.22') < 0) { $kernopts{HAS_IOMEM} = 2; } # Kernel < 2.6.22 is missing the HAS_DMA option if (!defined $kernopts{HAS_DMA} && cmp_ver($kernver, '2.6.22') < 0) { $kernopts{HAS_DMA} = 2; } # Kernel < 2.6.23 is missing the VIRT_TO_BUS option if (!defined $kernopts{VIRT_TO_BUS} && cmp_ver($kernver, '2.6.23') < 0) { # VIRT_TO_BUS -> !PPC64 $kernopts{VIRT_TO_BUS} = 2 - $kernopts{PPC64}; } # Kernel < 2.6.37 is missing the BKL option if (!defined $kernopts{BKL} && cmp_ver($kernver, '2.6.37') < 0) { $kernopts{BKL} = 2; } -- Cheers, Mauro
