359187d647 MIPS: R5000: Fix TLB hazard handling.
R5000 and the Nevada CPUs (RM5230, RM5231, RM5260, RM5261, RM5270 and
RM5271) are basically the same CPU core and all are documented to require
two instructions separating a write to c0_pagemask, c0_entryhi, c0_entrylo0,
c0_entrylo1 or c0_index.

So far we were only providing on cycle before / after a TLBR/TLBWI
for R5000 but 3 cycles before and 1 cycles after for the Nevadas.

02a5417751 MIPS: tlbex: Deal with re-definition of label
The microassembler used in tlbex.c does not notice if a label is redefined
resulting in relocations against such labels silently missrelocated.
The issues exists since commit add6eb04776db4189ea89f596cbcde31b899be9d
[Synthesize TLB exception handlers at runtime.] in 2.6.10 and went unnoticed
for so long because the relocations for the affected branches got computed
to do something *almost* sensible.

The issue affects R4000, R4400, QED/IDT RM5230, RM5231, RM5260, RM5261,
RM5270 and RM5271 processors.

5210edcd52 MIPS: Make __{,n,u}delay declarations match definitions and generic delay.h
At some recent point arch/mips/include/asm/delay.h has started being
included into csrc-octeon.c where the __?delay() functions are defined.
This causes a compile failure due to conflicting declarations and
definitions of the functions.

It turns out that the generic definitions in arch/mips/lib/delay.c also
conflict.

Proposed fix: Declare the functions to take unsigned long parameters
just like asm-generic (and x86) does.  Update __delay to agree
(__ndelay and __udelay need no change).

Bonus: Get rid of 'inline' from __delay() definition, as it is globally
visible, and the compiler should be making this decision itself (it does
in fact inline the function without being told to).

e793d8c674 sparc64: Fix bit twiddling in sparc_pmu_enable_event().
There was a serious disconnect in the logic happening in
sparc_pmu_disable_event() vs. sparc_pmu_enable_event().

Event disable is implemented by programming a NOP event into the PCR.

However, event enable was not reversing this operation.  Instead, it
was setting the User/Priv/Hypervisor trace enable bits.

That's not sparc_pmu_enable_event()'s job, that's what
sparc_pmu_enable() and sparc_pmu_disable() do .

The intent of sparc_pmu_enable_event() is clear, since it first clear
out the event type encoding field.  So fix this by OR'ing in the event
encoding rather than the trace enable bits.

9f0d3c2781 ipv6: addrconf: fix /proc/net/if_inet6
Commit 1d5783030a (ipv6/addrconf: speedup /proc/net/if_inet6 filling)
added bugs hiding some devices from if_inet6 and breaking applications.

"ip -6 addr" could still display all IPv6 addresses, while "ifconfig -a"
couldnt.

One way to reproduce the bug is by starting in a shell :

unshare -n /bin/bash
ifconfig lo up

And in original net namespace, lo device disappeared from if_inet6

2efaf5ff7f qeth: fix deadlock between recovery and bonding driver
The recovery thread, when failing, tears down the respective interface. To do
so, it needs to obtain the rtnl lock first, as the interface configuration is
changed.
If another process tries to modify an interface setting at the same time, that
process can obtain the rtnl lock first, but the respective callback in the qeth
driver will block until recovery has completed - which cannot happen since the
calling process already obtained it.
In one particular case, the bonding driver acquired the rtnl lock to modify the
card's MAC address, while the recovery failed at the same time due to the card
being removed. Hence qeth_l2_set_mac_address (implicitly holding the rtnl lock)
was waiting on qeth_l2_recover, which deadlocked when waiting on the rtnl lock.
This patch uses rtnl_trylock instead of rtnl_lock in the recovery thread. If the
lock cannot be obtained, the interface will be left up, but the card state
remains in CARD_STATE_RECOVER, which will prevent any further activities on the
card.

db5c8b5244 USB: fix port probing and removal in garmin_gps
This patch (as1615) fixes a bug in the Garmin USB serial driver.  It
uses attach, disconnect, and release routines to carry out actions
that should be handled by port_probe and port_remove routines, because
they access port-specific data.

The bug causes an oops when the device in unplugged, because the
private data for each port structure now gets erased when the port is
unbound from the driver, resulting in a null-pointer dereference.

With the introduction of fan management modes, fan may not be drivable.
We should allow reclocking nonetheless.

This return was stupid to begin with since it may have left the card
in an intermediate state (clocks corresponding to a perflvl and voltage
corresponding to another one). The reclocking code will need to be
rewritten in a near-future in order to provide a better error handling.

know what I was thinking.

This brings back changes made by commits 24cc7fb69a ("x86/kbuild:
archscripts depends on scripts_basic") and c1c1a59e37 ("firmware: fix
directory creation rule matching with make 3.80")

0829184711 drm/radeon: Don't destroy I2C Bus Rec in radeon_ext_tmds_enc_destroy().
radeon_i2c_fini() walks thru the list of I2C bus recs rdev->i2c_bus[]
to destroy each of them.
radeon_ext_tmds_enc_destroy() however also has code to destroy it's
associated I2C bus rec which has been obtained by radeon_i2c_lookup()
and is therefore also in the i2c_bus[] list.
This causes a double free resulting in a kernel panic when unloading
the radeon driver.
Removing destroy code from radeon_ext_tmds_enc_destroy() fixes this
problem.

c1a7ca0de3 drm/radeon/cayman: set VM max pfn at MC init
No need to emit them at VM flush as we no longer use
variable sized page tables now that we support 2 level
page tables.  This matches the behavior of SI (which
does not support variable sized page tables).

90a51a3292 drm/radeon: allocate page tables on demand v4
Based on Dmitries work, but splitting the code into page
directory and page table handling makes it far more
readable and (hopefully) more reliable.

Allocations of page tables are made from the SA on demand,
that should still work fine since all page tables are of
the same size.

Also using the fact that allocations from the SA are mostly
continuously (except for end of buffer wraps and under very
high memory pressure) to group updates send to the chipset
specific code into larger chunks.

v3: mostly a rewrite of Dmitries previous patch.
v4: fix some typos and coding style
