10326 SPARC boot fails with vmem_xalloc(): size overflow
Review Request #1415 — Created Jan. 30, 2019 and submitted
Booting a SPARC ISO with current bits panics (fairly late) with. vmem_xalloc(): size overflow On sun4u, boot_ncpus is set to -1, aggsum_init uses that verbatim and asks for a negative allocation. Fix courtesy of Igor Kozhukov is to set boot_ncpus on sun4u.
Tested and verified in DilOS; I;ll test this with current gate in Tribblix when I get some time.
