The mmu-gather operation 'tlb_flush_mmu()' has done two things: the
actual tlb flush operation, and the batched freeing of the pages that
the TLB entries pointed at.

This splits the operation into separate phases, so that the forced
batched flushing done by zap_pte_range() can now do the actual TLB flush
while still holding the page table lock, but delay the batched freeing
of all the pages to after the lock has been dropped.

This in turn allows us to avoid a race condition between
set_page_dirty() (as called by zap_pte_range() when it finds a dirty
shared memory pte) and page_mkclean(): because we now flush all the
dirty page data from the TLB's while holding the pte lock,
page_mkclean() will be held up walking the (recently cleaned) page
tables until after the TLB entries have been flushed from all CPU's.

The restart/power off implementation in the vexpress driver
used to obtain the config function when necessary. This was
wrong in two respects:

1. It required memory allocation with disabled interrupts
(it worked, but lockdep - when enabled - reported warnings).

2. Used jiffies-based timeout, while jiffies are not running
at this stage of system shutdown (therefore a config
transaction error - if happened - would have never be reported).

Fixed by pre-allocating the config function per device
and using mdelay for timeout.

At least the smc91x driver expects the device to be at 0x300
offset from bus base address. This does not work currently
for GPMC when booted in device tree mode as it attempts to
remap the the allocated GPMC partition to the address
configured by the device tree plus the device offset.

Note that this works just fine when booted with legacy mode.

Let's fix the issue by just ignoring any device specific
offset while remapping. And let's make sure the remap
address confirms to the GPMC 16MB minimum granularity
as listed in the TRM for GPMC_CONFIG7 BASEADDRESS bits.

Otherwise we can get something like this:

omap-gpmc 6e000000.gpmc: cannot remap GPMC CS 1 to 0x01000300

Pull input updates from Dmitry Torokhov:
 "The main change is that we now publish "firmware ID" for the serio
  devices to help userspace figure out the kind of touchpads it is
  dealing with: i8042 will export PS/2 port's PNP IDs as firmware IDs.

  You will also get more quirks for Synaptics touchpads in various
  Lenovo laptops, a change to elantech driver to recognize even more
  models, and fixups to wacom and couple other drivers"

("arm: dma-mapping: remove order parameter from
arm_iommu_create_mapping()") is causing kernel panic
because it wrongly sets the value of mapping->size:

Unable to handle kernel NULL pointer dereference at virtual
address 000000a0
pgd = e7a84000
[000000a0] *pgd=00000000
...
PC is at bitmap_clear+0x48/0xd0
LR is at __iommu_remove_mapping+0x130/0x164

Fix it by correcting mapping->size value.
