Commit d78114554939a (""ARM: 8512/1: proc-v7.S: Adjust stack address when
XIP_KERNEL"") introduced a macro which lives under asm/memory.h.
Unfortunately, for MMU-less systems (like R-class) it leads to build failure:
arch/arm/mm/proc-v7.S: Assembler messages:
arch/arm/mm/proc-v7.S:538: Error: unrecognised relocation suffix
make[1]: *** [arch/arm/mm/proc-v7.o] Error 1
make: *** [arch/arm/mm] Error 2
since it is implicitly pulled via asm/pgtable.h for MMU capable systems only.
To fix it include asm/memory.h explicitly.

Since we switched to use pxa_timer, we need to provide the OSTIMER0
clock. However, as the clock is initialised early, we need to provide
the clock early as well, so that pxa_timer can find it. Adding the
clock to the clkdev table at core_initcall() time is way too late.
Move the initialisation earlier.

- ITS init issues

At imx6ul_init_machine, it calls imx6ul_pm_init which needs to find
platform device for ocram, but the default populate platform device is at
of_platform_default_populate_init, which is located at arch_initcall_sync,
and called later than arch_initcall (.init_machine is located at that).
So below warning message will be showed during boots up:
imx6q_suspend_init: failed to find ocram device!
imx6_pm_common_init: No DDR LPM support with suspend -19!
Due to lack of ocram device, the suspend mode "mem" which needs ocram to
store suspend routine code is invalid.
This commit populates platform device before imx6ul_pm_init like other
imx6 platforms do, and the suspend mode "mem" can work successfully.

When converting a gfn to a pfn, we call gfn_to_pfn_prot, which returns
various kinds of error values. It turns out that is_error_pfn() only
returns true when the gfn was found in a memory slot and could somehow
not be used, but it does not return true if the gfn does not belong to
any memory slot.
Change use to is_error_noslot_pfn() which covers both cases.
Note: Since we already check for kvm_is_error_hva(hva) explicitly in the
caller of this function while holding the kvm->srcu lock protecting the
memory slots, this should never be a problem, but nevertheless this
change is warranted as it shows the intention of the code.

KVM devices were manipulating list data structures without any form of
synchronization, and some implementations of the create operations also
suffered from a lack of synchronization.
Now when we've split the xics create operation into create and init, we
can hold the kvm->lock mutex while calling the create operation and when
manipulating the devices list.
The error path in the generic code gets slightly ugly because we have to
take the mutex again and delete the device from the list, but holding
the mutex during anon_inode_getfd or releasing/locking the mutex in the
common non-error path seemed wrong.

- A fix for a realview regression that broke real hardware but
not the qemu model that everyone uses in practice (needed

Clearly QEMU is very permissive in how its PL310 model may be set up,
but the real hardware turns out to be far more particular about things
actually being correct. Fix up the DT description so that the real
thing actually boots:
- The arm,data-latency and arm,tag-latency properties need 3 cells to
be valid, otherwise we end up retaining the default 8-cycle latencies
which leads pretty quickly to lockup.
- The arm,dirty-latency property is only relevant to L210/L220, so get
rid of it.
- The cache geometry override also leads to lockup and/or general
misbehaviour. Irritatingly, the manual doesn't state the actual PL310
configuration, but based on the boardfile code and poking registers
from the Boot Monitor, it would seem to be 8 sets of 16KB ways.
With that, we can successfully boot to enjoy the fun of mismatched FPUs...

The crash is due to the fact that the UEFI page tables are not owned by
init_mm, but are not covered by fully constructed struct pages.
Given that the UEFI subsystem is currently the only user of
create_mapping_late(), add an unconditional call to pgtable_page_ctor() to
late_alloc().

To limit the amount of mapped low memory, we determine a physical address
boundary based on the start of the vmalloc area using __pa().
Strictly speaking, the vmalloc area location is arbitrary and does not
necessarily corresponds to a valid physical address. For example, if
PAGE_OFFSET = 0x80000000
PHYS_OFFSET = 0x90000000
vmalloc_min = 0xf0000000
then __pa(vmalloc_min) overflows and returns a wrapped 0 when phys_addr_t
is a 32-bit type. Then the code that follows determines that the entire
physical memory is above that boundary and no low memory gets mapped at
all:
|[...]
|Machine model: Freescale i.MX51 NA04 Board
|Ignoring RAM at 0x90000000-0xb0000000 (!CONFIG_HIGHMEM)
|Consider using a HIGHMEM enabled kernel.
To avoid this problem let's make vmalloc_limit a 64-bit value all the
time and determine that boundary explicitly without using __pa().

Currently, the ports as seen from the rear number as:
eth0 sfp lan5 lan4 lan3 lan2 lan1 lan6
which is illogical - this came about because the rev 2.0 boards have the
LEDs on the front for the DSA switch (lan5-1) reversed. Rev 2.1 boards
fixed the LED issue, and the Clearfog case numbers the lan ports
increasing from left to right.
Maintaining this illogical numbering causes confusion, with reports that
"my link isn't coming up" and "my connection negotiates 10base-Half"
both of which are due to people thinking that the port next to the SFP
is lan1.
Fix this by renumbering the ports to match people's expectations.

The dma-mapping core and the implementations do not change the DMA
attributes passed by pointer. Thus the pointer can point to const data.
However the attributes do not have to be a bitfield. Instead unsigned
long will do fine:
1. This is just simpler. Both in terms of reading the code and setting
attributes. Instead of initializing local attributes on the stack
and passing pointer to it to dma_set_attr(), just set the bits.
2. It brings safeness and checking for const correctness because the
attributes are passed by value.

Includes GSI routing support to go along with the new VGIC and a small fix that

The patch that this was preparing for made it into neither v4.7 nor
v4.8, so we should back this out as well to avoid the opposite
