Dear all, I build MIPS 32 with sparsemem support to take care of holes in physical memory, this conserve memory but put overhead to speed because of pointer redirection in pfn_to_page(). To prevent this conversion I tried to use CONFIG_SPARSEMEM_VMEMMAP_ENABLE on MIPS 32 but kernel build fails becauase most of the supported functions related to vmemmap are supported for 64 bit architectures only. I wish to compare memory and speed result with / without CONFIG_SPARSEMEM_VMEMMAP_ENABLE in MIPS 32. I need your comment in it ? Thanks
