linux/vmalloc.h added to zsmalloc-main.c to resolve implicit declaration errors. X86 dependency added to zsmalloc and dependent drivers zcache and zram. This X86 only requirement is not ideal. Working to find portable functions for __flush_tlb_one and set_pte.
sorry, zcache/zram works fine one ARM here. Why not depend on !POWERPC? Marc
