I believe that Stefan is working on a more general solution over in https://lkml.kernel.org/r/bdfa44bf1c570b05d6c70898e2bbb0acf234ecdf.1604762181.git.stefan@agner.ch

If CONFIG_ZSMALLOC is enabled with xtensa then the build fails with: mm/zsmalloc.c:43:10: fatal error: asm/sparsemem.h: No such file or directory Disable CONFIG_ZSMALLOC for xtensa as xtensa arch has not defined sparsemem.h.
