Since the introduction of preemptible mmu_gather TLB fast mode has been
broken. TLB fast mode relies on there being absolutely no concurrency;
it frees pages first and invalidates TLBs later.
However now we can get concurrency and stuff goes *bang*.
This patch removes all tlb_fast_mode() code; it was found the better
option vs trying to patch the hole by entangling tlb invalidation with
the scheduler.

Merge 'net' bug fixes into 'net-next' as we have patches
that will build on top of them.
This merge commit includes a change from Emil Goode
(emilgoode@gmail.com) that fixes a warning that would
have been introduced by this merge. Specifically it
fixes the pingv6_ops method ipv6_chk_addr() to add a
"const" to the "struct net_device *dev" argument and
likewise update the dummy_ipv6_chk_addr() declaration.

====================
this is a pull-request for net-next/master. It consists of two patches
by Fabio Estevam, cleaning up the flexcan driver (remove default
pinctrl and switch to SIMPLE_DEV_PM_OPS). A patch by me to simplify the
Kconfig [1] handling for flexcan. And a patch by Jingoo Han that
converts the can drivers to use platform_{get,set}_drvdata().
[1] My patch touches arch/{arm,powerpc}, so I collected Acked-bys from
Arnd Bergmann, Shawn Guo and Benjamin Herrenschmidt.

Some ARM KVM VCPU ioctls require the vCPU to be properly initialized
with the KVM_ARM_VCPU_INIT ioctl before being used with further
requests. KVM_RUN checks whether this initialization has been
done, but other ioctls do not.
Namely KVM_GET_REG_LIST will dereference an array with index -1
without initialization and thus leads to a kernel oops.
Fix this by adding checks before executing the ioctl handlers.

Here are a number of tiny USB bugfixes / new device ids for 3.10-rc2
The majority of these are USB gadget fixes, but they are all small.
Other than that, some USB host controller fixes, and USB serial driver
fixes for problems reported with them.
Also hopefully a fixed up USB_OTG Kconfig dependancy, that one seems to
be almost impossible to get right for all of the different platforms
these days.

Commit d3f79584a8 ("ARM: cleanup undefined instruction entry code")
improved the register scheduling when handling undefined instructions.
A side effect of this is that r5 is now used as a temporary, whilst the
VFP probing code relies on r5 containing a non-zero value when VFP is
not supported.
This patch fixes the VFP detection code so that we don't rely on the
contents of r5. Without this patch, Linux dies loudly on CPUs without
VFP support.

If one reads /proc/$PID/smaps, the mmap_sem belonging to the
address space of the task being examined is locked for reading.
All the pages of the vmas belonging to the task's address space
are then walked with this lock held.
If a gate_vma is present in the architecture, it too is examined
by the fs/proc/task_mmu.c code. As gate_vma doesn't belong to the
address space of the task though, its pages are not walked.
A recent cleanup (commit f6604efe) of the gate_vma initialisation
code set the vm_mm value to &init_mm. Unfortunately a non-NULL
vm_mm value in the gate_vma will cause the task_mmu code to attempt
to walk the pages of the gate_vma (with no mmap-sem lock held). If
one enables Transparent Huge Page support and vm debugging, this
will then cause OOPses as pmd_trans_huge_lock is called without
mmap_sem being locked.
This patch removes the .vm_mm value from gate_vma, restoring the
original behaviour of the task_mmu code.

This patch updates the marzen board code as if USB PHY isn't enabled
they phy will have a value set by ERR_PTR() rather than be NULL.
Without this patch a NULL pointer dereference and kernel panic
occurs on initialisation of USB on marzen.
This resolves a regression introduced in 3.10-rc1 by
b7fa5c2aec

Before f7b861b7a6 ("arm: Use generic idle loop") ARM would kill the
CPU within the rcu idle section. Now that the rcu_idle_enter()/exit()
pair have been pushed lower down in the idle loop this is no longer true
and so using RCU_NONIDLE here is no longer necessary and also harmful
because RCU is not actually idle at this point.

The assignment of IRQ for the SMC91x ethernet adapter had two
problems making it non-working:
- It was not put into the ethernet device node. Let's do this
by using the board-specific overlay, so we can make other
overlays on other Nomadik boards.
- The IRQ number was actually completely wrong, this was the
number for NHK8815, not S8815.
After this ethernet starts working on the USB S8815.

When I tried booting a stih415 Dual core A9 with multi_v7_defconfig, it
failed to boot. The issues seems to be changing by enabling or disabling
VT8550 platform. Having a quick look at dt_compat list, it seems to miss
a NULL terminator, which means of_flat_dt_match will compat check will
cross the boundary of dt_compat and fault at some point , which is what
was happening in my case.
Without this patch if we try to boot multi_v7_defconfig you might notice
that some of the platforms might fault if they fall after vt8500 in
machine-desc list. Other platforms which fall before vt8500 in mdesc list
will not fault.
