'default n' is the default value for any bool or tristate Kconfig
setting so there is no need to write it explicitly.
Also since commit f467c5640c ("kconfig: only write '# CONFIG_FOO
is not set' for visible symbols") the Kconfig behavior is the same
regardless of 'default n' being present or not:
...
One side effect of (and the main motivation for) this change is making
the following two definitions behave exactly the same:
config FOO
bool
config FOO
bool
default n
With this change, neither of these will generate a
'# CONFIG_FOO is not set' line (assuming FOO isn't selected/implied).
That might make it clearer to people that a bare 'default n' is
redundant.

This enables support for IBM Virtual Accelerator Switchboard (VAS).
|

VAS allows accelerators in co-processors like NX-GZIP and NX-842
|
|
to be accessible to kernel subsystems and user processes.
|
|
|
|
VAS adapters are found in POWER9 based systems.
