David S. Miller 79b3891587 irda: iriap: Use seperate lockdep class for irias_objects->hb_spinlock
The SEQ output functions grab the obj->attrib->hb_spinlock lock of
sub-objects found in the hash traversal.  These locks are in a different
realm than the one used for the irias_objects hash table itself.

So put the latter into it's own lockdep class.

David S. Miller 3019de124b net: Rework netdev_drivername() to avoid warning.
This interface uses a temporary buffer, but for no real reason.
And now can generate warnings like:

net/sched/sch_generic.c:254:10: warning: unused variable drivername

Just return driver->name directly or "".

The funtion option_send_status times out when sending USB messages

Dan Williams 15badbcc8e option: add Alcatel X200 to sendsetup blacklist
This modem really wants sendsetup blacklisted for interfaces 0 and 1,
otherwise the kernel hardlocks for about 10 seconds while waiting for
the modem's firmware to respond, which it of course doesn't do.

A slight complication here is that TCT (who owns the Alcatel brand) used
the same USB IDs for the X200 as the X060s despite the devices having
completely different firmware and AT command sets, so we end up adding
the X060s to the blacklist at the same time.  PSA to OEMs: don't use the
same USB IDs for different devices.  Really.  It makes your kittens cry.

the value provided by the user is used... Except when the SWIOTLB
is used under Xen - there the default value of 64MB is used and
the Xen-SWIOTLB has no mechanism to get the 'io_tlb_nslabs' filled
out by setup_io_tlb_npages functions. This patch provides a function
for the Xen-SWIOTLB to call to see if the io_tlb_nslabs is set

Stanislaw Gruszka 42b70a5f6d iwlagn: use cts-to-self protection on 5000 adapters series
This patch fixes 802.11n stability and performance regression we have
since 2.6.35. It boost performance on my 5GHz N-only network from about
5MB/s to 8MB/s. Similar percentage boost can be observed on 2.4 GHz.

These are test results of 5x downloading of approximately 700MB iso
image:

vanilla: 5.27 5.22 4.94 4.47 5.31 ; avr 5.0420 std 0.35110
patched: 8.07 7.95 8.06 7.99 7.96 ; avr 8.0060 std 0.055946

This was achieved with NetworkManager configured to do not perform
periodical scans, by configuring constant BSSID. With periodical scans,
after some time, performance downgrade to unpatched driver level, like
in example below:

patched: 7.40 7.61 4.28 4.37 4.80 avr 5.6920 std 1.6683

However patch still make better here, since similar test on unpatched
driver make link disconnects with below messages after some time:

wlan1: authenticate with 00:23:69:35:d1:3f (try 1)
wlan1: authenticate with 00:23:69:35:d1:3f (try 2)
wlan1: authenticate with 00:23:69:35:d1:3f (try 3)
wlan1: authentication with 00:23:69:35:d1:3f timed out

On 2.6.35 kernel patch helps against connection hangs with messages:

iwlagn 0000:20:00.0: queue 10 stuck 3 time. Fw reload.
iwlagn 0000:20:00.0: On demand firmware reload

Joerg Roedel 0de66d5b35 x86/amd-iommu: Fix 3 possible endless loops
The driver contains several loops counting on an u16 value
where the exit-condition is checked against variables that
can have values up to 0xffff. In this case the loops will
never exit. This patch fixed 3 such loops.

Martin Schwidefsky 6c61cfe91b [S390] fix kvm defines for 31 bit compile
KVM is not available for 31 bit but the KVM defines cause warnings:

arch/s390/include/asm/pgtable.h: In function 'ptep_test_and_clear_user_dirty':
arch/s390/include/asm/pgtable.h:817: warning: integer constant is too large for 'unsigned long' type
arch/s390/include/asm/pgtable.h:818: warning: integer constant is too large for 'unsigned long' type
arch/s390/include/asm/pgtable.h: In function 'ptep_test_and_clear_user_young':
arch/s390/include/asm/pgtable.h:837: warning: integer constant is too large for 'unsigned long' type
arch/s390/include/asm/pgtable.h:838: warning: integer constant is too large for 'unsigned long' type

Add 31 bit versions of the KVM defines to remove the warnings.

Martin Schwidefsky 36409f6353 [S390] use generic RCU page-table freeing code
Replace the s390 specific rcu page-table freeing code with the
generic variant. This requires to duplicate the definition for the
struct mmu_table_batch as s390 does not use the generic tlb flush
code.

While we are at it remove the restriction that page table fragments
can not be reused after a single fragment has been freed with rcu
and split out allocation and freeing of page tables with pgstes.

Jan Glauber 3ec90878ba [S390] qdio: Split SBAL entry flags
The qdio SBAL entry flag is made-up of four different values that are
independent of one another. Some of the bits are reserved by the
hardware and should not be changed by qdio. Currently all four values
are overwritten since the SBAL entry flag is defined as an u32.

Split the SBAL entry flag into four u8's as defined by the hardware
and don't touch the reserved bits.

Christian Borntraeger 9950f8be3f [S390] kvm-s390: fix stfle facilities numbers >=64
Currently KVM masks out the known good facilities only for the first
double word, but passed the 2nd double word without filtering. This
breaks some code on newer systems:

So lets also mask the 2nd double word. Facilites 66,76,76,77 should be fine.
