eb3836cefc staging: ft1000: function scram_start_dwnld extracted from scram_dnldr in ft1000_download.c
function scram_dnldr is over 500 lines long, with deep indents that
trigger checkpatch warnings for too many tabs. It mainly consists of a
switch statement with long, complicated cases. The first case has been
extracted to form the helper function scram_start_dwnld. Some style
issues in the extracted lines have been corrected as well.

4d4b69dd84 NFS: add support for multiple sec= mount options
This patch adds support for multiple security options which can be
specified using a colon-delimited list of security flavors (the same
syntax as nfsd's exports file).

This is useful, for instance, when NFSv4.x mounts cross SECINFO
boundaries. With this patch a user can use "sec=krb5i,krb5p"
to mount a remote filesystem using krb5i, but can still cross
into krb5p-only exports.

New mounts will try all security options before failing.  NFSv4.x
SECINFO results will be compared against the sec= flavors to
find the first flavor in both lists or if no match is found will
return -EPERM.

5837f6dfcb NFS: stop using NFS_MOUNT_SECFLAVOUR server flag
Since the parsed sec= flavor is now stored in nfs_server->auth_info,
we no longer need an nfs_server flag to determine if a sec= option was
used.

This flag has not been completely removed because it is still needed for
the (old but still supported) non-text parsed mount options ABI
compatability.

0f5f49b8b3 NFS: cache parsed auth_info in nfs_server
Cache the auth_info structure in nfs_server and pass these values to submounts.

This lays the groundwork for supporting multiple sec= options.

a3f73c27af NFS: separate passed security flavs from selected
When filling parsed_mount_data, store the parsed sec= mount option in
the new struct nfs_auth_info and the chosen flavor in selected_flavor.

This patch lays the groundwork for supporting multiple sec= options.

0625c2dd6a NFS: Fix possible endless state recovery wait
In nfs4_wait_clnt_recover(), hold a reference to the clp being
waited on.  The state manager can reduce clp->cl_count to 1, in
which case the nfs_put_client() in nfs4_run_state_manager() can
free *clp before wait_on_bit() returns and allows
nfs4_wait_clnt_recover() to run again.

The behavior at that point is non-deterministic.  If the waited-on
bit still happens to be zero, wait_on_bit() will wake the waiter as
expected.  If the bit is set again (say, if the memory was poisoned
when freed) wait_on_bit() can leave the waiter asleep.

This is a narrow fix which ensures the safety of accessing *clp in
nfs4_wait_clnt_recover(), but does not address the continued use
of a possibly freed *clp after nfs4_wait_clnt_recover() returns
(see nfs_end_delegation_return(), for example).

cd3fadece2 NFS: Set EXCHGID4_FLAG_SUPP_MOVED_MIGR
Broadly speaking, v4.1 migration is untested.  There are no servers
in the wild that support NFSv4.1 migration.  However, as server
implementations become available, we do want to enable testing by
developers, while leaving it disabled for environments for which
broken migration support would be an unpleasant surprise.
