Re: [PATCH v5 0/6] Add support for FORM2 associativity

Aneesh,

This series compiles with a configuration made with "pseries_le_defconfig"
but fails with a config based on an existing RHEL8 config.

The reason, which is hinted in the robot replies in patch 4, is that you defined
a "__vphn_get_associativity" inside a #ifdef CONFIG_PPC_SPLPAR guard but didn't
define how the function would behave without the config, and you ended up
using the function elsewhere.

This fixes the compilation but I'm not sure if this is what you intended
for this function:

I'll post a new version of the QEMU FORM2 changes using these patches as is (with
the above fixup), but I guess you'll want to post a v6.
