Implement intelligent backtracing by searching for stack frame creation,
and emitting only return addresses. Use print_hex_dump() to display the
entire binary kernel stack.
Limitation: MMU kernels are not currently able to trace beyond a system trap
(interrupt, syscall, etc.). It is the intent of this patch to provide
infrastructure that can be extended to add this capability later.
Changes from V1:
* Removed checks in find_frame_creation() that prevented location of the frame
creation instruction in heavily optimized code
* Various formatting/commenting/file location tweaks per review comments
* Dropped Kconfig option to enable STACKTRACE as something logically separate

copy_to_user_page macro is used in mm/memory.c:access_process_vm
function. This function is called from ptrace code (POKETEXT, POKEDATA)
which write data to memory. Microblaze handle physical address for
caches that's why there is virt_to_phys conversion.
There is potential one location which can caused the problem on WB system.
The important is take a look at write PTRACEs requests
(POKE/TEXT, DATA, USR).
Note:
Majority of Microblaze PTRACE code is moved to generic location
in newer kernel version that's why this solution should work on
the newest kernel version too.

This patch moves the declaration of of_get_address(), of_get_pci_address(),
and of_pci_address_to_resource() out of arch code and into the common
linux/of_address header file.
This patch also fixes some of the asm/prom.h ordering issues. It still
includes some header files that it ideally shouldn't be, but at least the
ordering is consistent now so that of_* overrides work.

Merge common irq mapping code between PowerPC and Microblaze.
This patch merges of_irq_find_parent(), of_irq_map_raw() and
of_irq_map_one(). The functions are dependent on one another, so all
three are merged in a single patch. Other than cosmetic difference
(ie. DBG() vs. pr_debug()), the implementations are identical.
of_irq_to_resource() is also merged, but in this case the
implementations are different. This patch drops the microblaze version
and uses the powerpc implementation unchanged. The microblaze version
essentially open-coded irq_of_parse_and_map() which it does not need
to do. Therefore the powerpc version is safe to adopt.

Now that the device tree node pointer has been moved out of struct
of_device and into the common struct device, there isn't anything
unique about of_device anymore. In fact, there isn't much need
for a separate of_bus when all busses have access to OF style
probing.
arch/powerpc and arch/microblaze are moving away from using the of_bus
and using the regular platform bus instead for mmio devices. This
patch makes of_device the same as platform_device as a stepping stone
in migrating of_platform_drivers over to the platform bus.

In old kernels, NET_SKB_PAD was defined to 16.
Then commit d6301d3dd1 (net: Increase default NET_SKB_PAD to 32), and
commit 18e8c134f4 (net: Increase NET_SKB_PAD to 64 bytes) increased it
to 64.
While first patch was governed by network stack needs, second was more
driven by performance issues on current hardware. Real intent was to
align data on a cache line boundary.
So use max(32, L1_CACHE_BYTES) instead of 64, to be more generic.
Remove microblaze and powerpc own NET_SKB_PAD definitions.

The trick for ISA_DMA_THRESHOLD in asm-generic/scatterlist.h doesn't work
