Tyler Hicks b2987a5e05 eCryptfs: Unlock keys needed by ecryptfsd
Fixes a regression caused by b5695d0463

Kernel keyring keys containing eCryptfs authentication tokens should not
be write locked when calling out to ecryptfsd to wrap and unwrap file
encryption keys. The eCryptfs kernel code can not hold the key's write
lock because ecryptfsd needs to request the key after receiving such a
request from the kernel.

Without this fix, all file opens and creates will timeout and fail when
using the eCryptfs PKI infrastructure. This is not an issue when using
passphrase-based mount keys, which is the most widely deployed eCryptfs
configuration.

Jean Delvare a095f687f1 hwmon: (lm90) Simplify handling of extended local temp register
The optional extended local temperature register can never have
address 0, as this address is already used by another register. Thus
we can get rid of flag LM90_HAVE_LOCAL_EXT and simply rely on
reg_local_ext being non-zero to determine if a given chip has this
extension or not. This makes the code more simple.

Lennart Sorensen 93a3aa2593 r8169: Add support for D-Link 530T rev C1 (Kernel Bug 38862)
The D-Link DGE-530T rev C1 is a re-badged Realtek 8169 named DLG10028C,
unlike the previous revisions which were skge based.  It is probably
the same as the discontinued DGE-528T (0x4300) other than the PCI ID.

The PCI ID is 0x1186:0x4302.

Adding it to r8169.c where 0x1186:0x4300 is already found makes the card
be detected and work.

To support providing those values as lowest/highest attributes to the user,

Guenter Roeck 9c1ed8941d hwmon: (pmbus) Add support for virtual pages
Some PMBus chips have non-standard sensor registers. An easy way to
support such sensors is to introduce virtual pages and map the non-standard
registers into standard registers on an extra page.

For this to work, the code verifying if the configured number of pages exists
has to be removed. Since a wrong number of pages can only be configured in a
front-end driver, this should not have a practical impact since the resulting
errors should be found during development and testing.

Also, functions to read the chip status while checking if a command register
exists must be modified to no longer set the page register before reading the
status, since the physical page associated with the checked register may not
exist. This does not make a functional difference since the page was already set
when the attempt to read the register was made.

Mauro Carvalho Chehab f7acc4bb86 [media] em28xx: Fix DVB-C maxsize for em2884
The logic at em28xx_isoc_dvb_max_packetsize() sucks, at least for newer
the needed packet size. Yet, it is better than nothing.

Rewrite the code in order to change the default to 752 for em2884 and
newer chips and provide a better way to handle per-chipset specifics.

For em2874, the current default should be enough, as the only em2874
board is currently a 1-seg ISDB-T board, so, it needs only a limited
amount of bandwidth.

Mauro Carvalho Chehab cf845297d5 [media] tda18271c2dd: Fix saw filter configuration for DVB-C @6MHz
Currently, the driver assumes that all QAM carriers are spaced with
8MHz. This is wrong, and may decrease QoS on Countries like Brazil,
that have DVB-C carriers with 6MHz-spaced.

Fortunately, both ITU-T J-83 and EN 300 429 specifies a way to
associate the symbol rate with the bandwidth needed for it.

For ITU-T J-83 2007 annex A, the maximum symbol rate for 6 MHz is:
	6 MHz / 1.15 = 5217391 Bauds
For  ITU-T J-83 2007 annex C, the maximum symbol rate for 6 MHz is:
	6 MHz / 1.13 = 5309735 Bauds.

As this tuner is currently used only for DRX-K, and it is currently
hard-coded to annex A, I've opted to use the roll-off factor of 0.15,
instead of 0.13.

If we ever support annex C, the better would be to add a DVB S2API
call to allow changing between Annex A and C, and add the 0.13 roll-off
factor to it.

This code is currently being used on other frontends, so I think we
should later add a core function with this code, to warrant that
it will be properly implemented everywhere.

Jean-Christophe PLAGNIOL-VILLARD 8c3583b634 at91: use structure to store the current soc
instead of reading the registers everytime

the current implementation respect the following constrain:
 - allow 1 to n soc to be enabled
 - allow to have a virtual cpu type and subtype
 - always detect the cpu type and subtype and report it
 - detect if the soc support is enabled
 - prepare for sysfs export support
 - drop soc specific code via compiler when the soc not enabled
   (via cpu_is_xxx)

Today if we read the exid we will have the same value for 9g35 and 9m11
and we will need to check the cidr too

with the new implementation we just need to check the soc subtype

this will also allow to have specific virtual subtype for rm9200 which the
board will have to specify via at91rm9200_set_type(int) as we have no way to
detect it.

this implementation is inspired by the SH cpu detection support

Reduce high order allocations in do_tune_cpucache() for some setups.
(NR_CPUS=4096 -> we need 64KB)

David S. Miller eb7caf3595 n2_crypto: Attach on Niagara-T3.
A small modification was necessary since in the machine description
for 'n2cp' and 'ncp' nodes, there no longer is an 'intr' property.

That's OK because this property was always nothing more than an
array of integers '1' ... 'nr_inos + 1' so we can just compute it
in-place.

And stop referring to Victoria Falls, as the attribute we're
talking about is whether the rng is multi-unit capable which
applies to several chip variants now.

Vasu Dev d272281c39 [SCSI] fcoe: cleanup cpu selection for incoming requests
Cleanup to:

- have selection for all types of frames, not just FCP.
- remove redundant cpu_online check once fcoe_select_cpu called
  as this is not required since later code flow check for offlined
  cpu.
- Simplify fcoe_select_cpu() by removing unnecessary checks to
  skip curr_cpu, this also fixes possibly infinite loop in case
  of curr_cpu is the only cpu while iterating in the loop.

This cleanup mainly applies to target as incoming request are
mostly for target, therefore Kiran has verified the patch
with target also.

Vasu Dev 980f5156ab [SCSI] fcoe: add fip retry to avoid missing critical keep alive
Use pending queue to retry FIP frame in case its tx
fails and use common pending queue for both fcoe

removing this warn on.

Neerav Parikh c9d24a7618 [SCSI] libfc: Remove the reference to FCP packet from scsi_cmnd in case of error
fc_queuecommand() allocates an FCP packet for each SCSI command and sends
it out on the wire. In the process it stores the reference to the FCP packet
in the scsi_cmnd structure.
Now, in case under stress testing the libfc exchange layer runs out of
exchanges the fc_queuecommand() may not be able to send out commands out on
the wire. In such a scenario if there is an error in sending the FCP packet
out the wire; fc_queuecommand() deletes the FCP packet from internal queue,
releases the FCP packet and returns a SCSI_MLQUEUE_HOST_BUSY status to the
scsi-ml. But, the reference to the FCP packet set in the scsi_cmnd is not
removed from the scsi_cmnd in this code path.

This might lead to a crash under stress testing where the scsi_cmnd failed by
fc_queuecommand() comes up to fc_eh_abort() via scsi eh thread. fc_eh_abort()
will get reference to the FCP packet to be aborted from the scsi_cmnd for
further FCP abort related processing and then try to release the FCP packet
that has already been released.

This patch removes the FCP packet reference from the scsi_cmnd before returning
back from fc_queuecommand() in case of an error in sending out the FCP packet.
