powerpc used to set the pte specific flags in set_pte_at(). This is different

set_pte_at() should not be used to set a pte entry at locations that
already holds a valid pte entry. Architectures like ppc64 don't do TLB

that are not a valid PTE.

Saved write support was added to track the write bit of a pte after marking the

and still track the old write bit. When converting it back we set the pte write

When H_SEND_CRQ command returns with H_CLOSED, it means the
server's CRQ is not ready yet. Instead of resetting immediately,
we wait for the server to launch passive init.
ibmvnic_init() and ibmvnic_reset_init() should also return the
error code from ibmvnic_send_crq_init() call.

At the beginning of the function, from_passive_init is set false by
