Could you please describe the use case where the ops is null.

We have to return the boolean here if the tag presents
or not, not just ANDing the TCI with the mask which results to:
[ 709.412097] test_bpf: #18 LD_VLAN_TAG_PRESENT

To get a full tag (and not just a VID) we should access the TCI
except the VLAN_TAG_PRESENT field (which means that 802.1q header
is present). Also ensure that the VLAN_TAG_PRESENT stay on its place

We have to return the boolean here if the tag presents
or not, not jusr ORing the TCI with the mask which results to:
[ 709.412097] test_bpf: #18 LD_VLAN_TAG_PRESENT

Commit 801eb73f45371accc78ca9d6d22d647eeb722c11 introduced
a bug while checking PTE flags. We have to drop the _PAGE_COHERENT flag
when __PAGE_NO_CACHE is set and the cache update policy is not write-through
(i.e. _PAGE_WRITETHRU is not set)

have to try to compile with g5_defconfig...

I don't know if this is a right fix for the problem
since of_get_property can return NULL.
Since iseries_device_information is used only for informational purpose,
we can skip this function without valid HvSubBusNumber number.
