mator@ttip:~/dmesg$ zcat config-6.0.0-rc6-00010-gb7f0f527dc3c.gz | grep VMEMMAP
CONFIG_SPARSEMEM_VMEMMAP_ENABLE=y
CONFIG_SPARSEMEM_VMEMMAP=y

I do upload config and boot logs to
https://github.com/mator/sparc64-dmesg

building a new kernel version/releases as 'make olddefconfig && make -j'
current version of booted 6.0.0-rc6 is available as
https://github.com/mator/sparc64-dmesg/blob/master/config-6.0.0-rc6-00010-gb7f0f527dc3c.gz
