For some silly reason (see comment in arch/sparc64/include/vmparam.h)
sparc64 always uses 32bit VM limits - for example the maximum stack
size is 8 MB.

>How-To-Repeat:
code inspection
>Fix:
When fixing this, VM_TOPDOWN should be added too

 Committed By:	martin

 Modified Files:
 	src/sys/arch/sparc64/include: vmparam.h

 Log Message:
 PR 32999: adjust VM parameters for 64 bit kernel/userlands.
 Limit old binaries (i.e. processes not using topdown VA layout) to 2 GB
 data size.
 Use the same limits as native sparc for netbsd32 emulation - we need to
 revisit this, but currently automatic test runs in this environment
 fail big time, so there is no easy way to verify any changes.
