With the following CR got integrated into SNV_113 and S10U8,
6811473 VPM interfaces should provide multiple pagelength mappings per request,
we see the following changes

1. VPM is enabled by default for SPARC platform also
2. Multi page length support improves the sendfilev performance

SPARC:

By default VPM is enabled.

1. To enable segmap/KPM, add the following in /etc/system
   set vpm_enable = 0
2. To enable segmap, add the following in /etc/system
   set kpm_enable = 0

x86:

By default segmap is enabled.

x64:

By default VPM is enabled.

1. To enable segmap/KPM, add the following in /etc/system
   set vpm_enable = 0
