022b660ae5 ccwgroup: Unify parsing for group attribute.
Instead of having each driver for ccwgroup slave device parsing the
input itself and calling ccwgroup_create(), introduce a new function
ccwgroup_create_from_string() and handle parsing inside the ccwgroup
core.

461e6c856f xfrm: alg_key_len & alg_icv_len should be unsigned
In commit ba749ae98d ([XFRM]: alg_key_len
should be unsigned to avoid integer divides
<http://git2.kernel.org/?p=linux/kernel/git/davem/net-2.6.git;a=commitdiff;h=ba749ae98d5aa9d2ce9a7facde0deed454f92230>)
alg_key_len field of struct xfrm_algo was converted to unsigned int to
avoid integer divides.

Then Herbert in commit 1a6509d991
([IPSEC]: Add support for combined mode algorithms) added a new
structure xfrm_algo_aead, that resurrected a signed int for alg_key_len
and re-introduce integer divides.

This patch avoids these divides and saves 64 bytes of text on i386.

f62220d3a9 phylib: Add support for board-level PHY fixups
Sometimes the specific interaction between the platform and the PHY
requires special handling.  For instance, to change where the PHY's
clock input is, or to add a delay to account for latency issues in the
data path.  We add a mechanism for registering a callback with the PHY
Lib to be called on matching PHYs when they are brought up, or reset.

c9c1014b2b [RTNETLINK]: Fix bogus ASSERT_RTNL warning
ASSERT_RTNL uses mutex_trylock to test whether the rtnl_mutex is
held. This bogus warnings when running in atomic context, which
f.e. happens when adding secondary unicast addresses through
macvlan or vlan or when synchronizing multicast addresses from
wireless devices.

Mid-term we might want to consider moving all address updates
to process context since the locking seems overly complicated,
for now just fix the bogus warning by changing ASSERT_RTNL to
use mutex_is_locked().

d619ee0849 mac80211: update mesh EID values
This patch updates mesh EID values, some of which where conflicting with
already-approved 11h EIDs (pointed out by Tomas Winkler). I wanted to use the
values suggested in the last available 802.11 draft (2.0) but it assigns 50 to
MESH_CONFIG, the same value than EXT_SUPP_RATES. Using the values proposed in
the draft incremented by one.

c5d18e984a [IPSEC]: Fix catch-22 with algorithm IDs above 31
As it stands it's impossible to use any authentication algorithms
with an ID above 31 portably.  It just happens to work on x86 but
fails miserably on ppc64.

The reason is that we're using a bit mask to check the algorithm
ID but the mask is only 32 bits wide.

After looking at how this is used in the field, I have concluded
that in the long term we should phase out state matching by IDs
because this is made superfluous by the reqid feature.  For current
applications, the best solution IMHO is to allow all algorithms when
the bit masks are all ~0.

The following patch does exactly that.

This bug was identified by IBM when testing on the ppc64 platform
using the NULL authentication algorithm which has an ID of 251.

076c54c5bc Security: Introduce security= boot parameter
Add the security= boot parameter. This is done to avoid LSM
registration clashes in case of more than one bult-in module.

User can choose a security module to enable at boot. If no
security= boot parameter is specified, only the first LSM
asking for registration will be loaded. An invalid security
module name will be treated as if no module has been chosen.

LSM modules must check now if they are allowed to register
by calling security_module_enable(ops) first. Modify SELinux
and SMACK to do so.

Do not let SMACK register smackfs if it was not chosen on
boot. Smackfs assumes that smack hooks are registered and
the initial task security setup (swapper->security) is done.

Introduce inode_getsecid(inode, secid) and ipc_getsecid(ipcp, secid)

SELinux interfaces.

Let {inode,ipc,task}_getsecid hooks set the secid to 0 by default
if CONFIG_SECURITY is not defined or if the hook is set to
NULL (dummy). This is done to notify the caller that no valid
secid exists.

This deblats ~200 bytes when ipv6 and dccp are 'y'.

Besides, this will ease compilation issues for patches

e56d8b8a2e [INET]: Drop the inet_inherit_port() call.
As I can see from the code, two places (tcp_v6_syn_recv_sock and
dccp_v6_request_recv_sock) that call this one already run with
BHs disabled, so it's safe to call __inet_inherit_port there.

Besides (in case I missed smth with code review) the calltrace
tcp_v6_syn_recv_sock
 `- tcp_v4_syn_recv_sock
     `- __inet_inherit_port
and the similar for DCCP are valid, but assumes BHs to be disabled.

93de00fd1c ide: remove broken/dangerous HDIO_[UNREGISTER,SCAN]_HWIF ioctls (take 3)
hdparm explicitely marks HDIO_[UNREGISTER,SCAN]_HWIF ioctls as DANGEROUS
and given the number of bugs we can assume that there are no real users:

* DMA has no chance of working because DMA resources are released by
  ide_unregister() and they are never allocated again.

* Since ide_init_hwif_ports() is used for ->io_ports[] setup the ioctls
  don't work for almost all hosts with "non-standard" (== non ISA-like)
  layout of IDE taskfile registers (there is a lot of such host drivers).

* ide_port_init_devices() is not called when probing IDE devices so:
  - drive->autotune is never set and IDE host/devices are not programmed
    for the correct PIO/DMA transfer modes (=> possible data corruption)
  - host specific I/O 32-bit and IRQ unmasking settings are not applied
    (=> possible data corruption)
  - host specific ->port_init_devs method is not called (=> no luck with
    ht6560b, qd65xx and opti621 host drivers)

* ->rw_disk method is not preserved (=> no HPT3xxN chipsets support).

* ->serialized flag is not preserved (=> possible data corruption when
   using icside, aec62xx (ATP850UF chipset), cmd640, cs5530, hpt366
   (HPT3xxN chipsets), rz1000, sc1200, dtc2278 and ht6560b host drivers).

* ->ack_intr method is not preserved (=> needed by ide-cris, buddha,
  gayle and macide host drivers).

* ->sata_scr[] and sata_misc[] is cleared by ide_unregister() and it
  isn't initialized again (SiI3112 support needs them).

* To issue an ioctl() there need to be at least one IDE device present
  in the system.

* ->cable_detect method is not preserved + it is not called when probing
  IDE devices so cable detection is broken (however since DMA support is
  also broken it doesn't really matter ;-).

* Some objects which may have already been freed in ide_unregister()
  are restored by ide_hwif_restore() (i.e. ->hwgroup).

* ide_register_hw() may unregister unrelated IDE ports if free ide_hwifs[]
  slot cannot be found.

* When IDE host drivers are modular unregistered port may be re-used by
  different host driver that owned it first causing subtle bugs.

Since we now have a proper warm-plug support remove these ioctls,
then remove no longer needed:
- ide_register_hw() and ide_hwif_restore() functions
- 'init_default' and 'restore' arguments of ide_unregister()
- zeroeing of hwif->{dma,extra}_* fields in ide_unregister()

As an added bonus IDE core code size shrinks by ~3kB (x86-32).

v2:
* fix ide_unregister() arguments in cleanup_module() (Andrew Morton).

v3:
* fix ide_unregister() arguments in palm_bk3710.c.

50672e5d74 ide: remove dead/obsolete ->busproc method
->busproc method is used by HDIO_SET_BUSSTATE ioctl but it has no chance
of working as intended (in 2.4.x days) because to issue an ioctl there
is a device node needed and:

- for BUSSTATE_TRISTATE+OFF it is too late (devices are already gone)

- for BUSSTATE_TRISTATE+ON it is too early (devices are not registered yet)

Rework PowerMac media-bay support in such way that instead of

* Add ide_port_scan() helper for probing+registerering devices on a port.

* Rename ide_port_unregister_devices() to __ide_port_unregister_devices().

* Add ide_port_unregister_devices() helper for unregistering devices on a port.

* Add 'ide_hwif_t *cd_port' to 'struct media_bay_info', pass 'hwif' instead
  of hwif->index to media_bay_set_ide_infos() and use it to setup 'cd_port'.

* Use ide_port_unregister_devices() instead of ide_unregister()
  and ide_port_scan() instead of ide_register_hw() in media_bay_step().

* Unexport ide_register_hw() and make it static.

v2:
* Fix build by adding <linux/ide.h> include to <asm-powerpc/mediabay.h>.
