afs: Use rxgk RESPONSE to pass token for callback channel
...
Implement in kafs the hook for adding appdata into a RESPONSE packet
generated in response to an RxGK CHALLENGE packet, and include the key for
securing the callback channel so that notifications from the fileserver get
encrypted.
This will be necessary when more complex notifications are used that convey
changed data around.

afs: Use new netfs lib read helper API
...
Make AFS use the new netfs read helpers to implement the VM read
operations:
- afs_readpage() now hands off responsibility to netfs_readpage().
- afs_readpages() is gone and replaced with afs_readahead().
- afs_readahead() just hands off responsibility to netfs_readahead().
These make use of the cache if a cookie is supplied, otherwise just call
the ->issue_op() method a sufficient number of times to complete the entire
request.
Changes:
v5:
- Use proper wait function for PG_fscache in afs_page_mkwrite()[1].
- Use killable wait for PG_writeback in afs_page_mkwrite()[1].
v4:
- Folded in error handling fixes to afs_req_issue_op().
- Added flag to netfs_subreq_terminated() to indicate that the caller may
have been running async and stuff that might sleep needs punting to a
workqueue.

fs/afs: remove depends on CONFIG_EXPERIMENTAL
...
The CONFIG_EXPERIMENTAL config item has not carried much meaning for a
while now and is almost always enabled by default. As agreed during the
Linux kernel summit, remove it from any "depends on" lines in Kconfigs.

DNS: Make AFS go to the DNS for AFSDB records for unknown cells
...
Add DNS query support for AFS so that it can get the IP addresses of Volume
Location servers from the DNS using an AFSDB record.
This requires userspace support. /etc/request-key.conf must be configured to
invoke a helper for dns_resolver type keys with a subtype of "afsdb:" in the
description.
