In my config file I have: CONFIG_HAVE_SPARSE_IRQ=y CONFIG_SPARSE_IRQ=y CONFIG_ARCH_SPARSEMEM_ENABLE=y # CONFIG_SPARSEMEM_MANUAL is not set CONFIG_SPARSEMEM_STATIC=y # CONFIG_INPUT_SPARSEKMAP is not set # CONFIG_SPARSE_RCU_POINTER is not set Is that sufficient for sparse memory, or should I try something else? Or maybe, you meant that some kernel source patches might be possible in the sparse memory code?
