staging: fix powerpc linux-next break on zsmalloc
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. Signed-off-by: Seth Jennings <sjenning@linux.vnet.ibm.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
