49a9072f29 SUNRPC: Remove @family argument from svc_create() and svc_create_pooled()
Since an RPC service listener's protocol family is specified now via
svc_create_xprt(), it no longer needs to be passed to svc_create() or
svc_create_pooled().  Remove that argument from the synopsis of those
functions, and remove the sv_family field from the svc_serv struct.

9652ada3fb SUNRPC: Change svc_create_xprt() to take a @family argument
The sv_family field is going away.  Pass a protocol family argument to
svc_create_xprt() instead of extracting the family from the passed-in
svc_serv struct.

Again, as this is a listener socket and not an address, we make this
new argument an "int" protocol family, instead of an "sa_family_t."

4b62e58ccc SUNRPC: Pass a family argument to svc_register()
The sv_family field is going away.  Instead of using sv_family, have
the svc_register() function take a protocol family argument.

Since this argument represents a protocol family, and not an address
family, this argument takes an int, as this is what is passed to
sock_create_kern().  Also make sure svc_register's helpers are
checking for PF_FOO instead of AF_FOO.  The value of [AP]F_FOO are
equivalent; this is simply a symbolic change to reflect the semantics
of the value stored in that variable.

sock_create_kern() should return EPFNOSUPPORT if the passed-in
protocol family isn't supported, but it uses EAFNOSUPPORT for this
case.  We will stick with that tradition here, as svc_register()
is called by the RPC server in the same path as sock_create_kern().

65fc73ac4a nl80211: Remove NL80211_CMD_SET_MGMT_EXTRA_IE
The functionality that NL80211_CMD_SET_MGMT_EXTRA_IE provided can now
be achieved with cleaner design by adding IE(s) into
NL80211_CMD_TRIGGER_SCAN, NL80211_CMD_AUTHENTICATE,
NL80211_CMD_ASSOCIATE, NL80211_CMD_DEAUTHENTICATE, and
NL80211_CMD_DISASSOCIATE.

Since this is a very recently added command and there are no known (or
known planned) applications using NL80211_CMD_SET_MGMT_EXTRA_IE and
taken into account how much extra complexity it adds to the IE
processing we have now (and need to add in the future to fix IE order
in couple of frames), it looks like the best option is to just remove
the implementation of this command for now. The enum values themselves
are left to avoid changing the nl80211 command or attribute numbers.

636a5d3625 nl80211: Add MLME primitives to support external SME
This patch adds new nl80211 commands to allow user space to request
authentication and association (and also deauthentication and
disassociation). The commands are structured to allow separate
authentication and association steps, i.e., the interface between
kernel and user space is similar to the MLME SAP interface in IEEE
802.11 standard and an user space application takes the role of the
SME.

The patch introduces MLME-AUTHENTICATE.request,
MLME-{,RE}ASSOCIATE.request, MLME-DEAUTHENTICATE.request, and
MLME-DISASSOCIATE.request primitives. The authentication and
association commands request the actual operations in two steps
(assuming the driver supports this; if not, separate authentication
step is skipped; this could end up being a separate "connect"
command).

The initial implementation for mac80211 uses the current
net/mac80211/mlme.c for actual sending and processing of management
frames and the new nl80211 commands will just stop the current state
machine from moving automatically from authentication to association.
Future cleanup may move more of the MLME operations into cfg80211.

The goal of this design is to provide more control of authentication and
association process to user space without having to move the full MLME
implementation. This should be enough to allow IEEE 802.11r FT protocol
and 802.11s SAE authentication to be implemented. Obviously, this will
also bring the extra benefit of not having to use WEXT for association
requests with mac80211. An example implementation of a user space SME
using the new nl80211 commands is available for wpa_supplicant.

This patch is enough to get IEEE 802.11r FT protocol working with
over-the-air mechanism (over-the-DS will need additional MLME
primitives for handling the FT Action frames).

6039f6d23f nl80211: Event notifications for MLME events
Add new nl80211 event notifications (and a new multicast group, "mlme")
for informing user space about received and processed Authentication,
(Re)Association Response, Deauthentication, and Disassociation frames in
station and IBSS modes (i.e., MLME SAP interface primitives
MLME-AUTHENTICATE.confirm, MLME-ASSOCIATE.confirm,
MLME-REASSOCIATE.confirm, MLME-DEAUTHENTICATE.indicate, and
MLME-DISASSOCIATE.indication). The event data is encapsulated as the 802.11
management frame since we already have the frame in that format and it
includes all the needed information.

This is the initial step in providing MLME SAP interface for
authentication and association with nl80211. In other words, kernel code
will act as the MLME and a user space application can control it as the
SME.

cc0be3227d net: Add missing include into include/linux/netdevice.h
The inline function skb_gro_mac_header defined in include/linux/netdevice.h
makes use of page_address(). Depending on configuration options, the latter

include include/linux/mm.h.

On MIPS, this has produced the following build error:

03a971a289 thermal: support forcing support for passive cooling
Due to poor thermal design or Linux driving hardware outside its thermal
envelope, some systems will reach critical temperature and shut down
under high load. This patch adds support for forcing a polling-based
passive trip point if the firmware doesn't provide one. The assumption
is made that the processor is the most practical means to reduce the
dynamic heat generation, so hitting the passive thermal limit will cause
the CPU to be throttled until the temperature stabalises around the
defined value.

UI is provided via a "passive" sysfs entry in the thermal zone
directory. It accepts a decimal value in millidegrees celsius, or "0" to
disable the functionality. Default behaviour is for this functionality
to be disabled.

a3ec947c85 vfs: simple_set_mnt() should return void
simple_set_mnt() is defined as returning 'int' but always returns 0.
Callers assume simple_set_mnt() never fails and don't properly cleanup if
it were to _ever_ fail.  For instance, get_sb_single() and get_sb_nodev()
should:

        up_write(sb->s_unmount);
        deactivate_super(sb);

if simple_set_mnt() fails.

Since simple_set_mnt() never fails, would be cleaner if it did not
return anything.

it's trivial.  This was suggested by Arnd Bergmann.

* Rename ->nsect field to ->nbytes in struct ide_cmd and use
  ->nbytes, ->nleft and ->cursg_ofs to keep track of number of
  bytes instead of sectors.

* Rename dma_timer_expiry() to ide_dma_sff_timer_expiry() and export it.

* Add ->dma_timer_expiry method and use it to set hwif->expiry for
  ATA_PROT_DMA protocol in do_rw_taskfile().

* Initialize ->dma_timer_expiry to ide_dma_sff_timer_expiry() for SFF hosts.

* Move setting hwif->expiry from ide_execute_command() to its users and drop
  'expiry' argument.

* Use ide_execute_command() instead of ->dma_exec_cmd in do_rw_taskfile().

* Remove ->dma_exec_cmd method and its implementations.

* Unexport ide_execute_command() and ide_dma_intr().

v2:
* Fix CONFIG_BLK_DEV_IDEDMA=n build (noticed by Randy Dunlap).

* Fix *dma_expiry naming (suggested by Sergei Shtylyov).

  requests can be marked as "noretry" so there is no change in behavior).
