Pull DT C pre-processor changes from Stephen Warren:
dt: run C pre-processor on *.dts, create some standard headers
This branch enhances the support for running dtc on device tree files.
A dedicated directory is created for header files that provide constants
for device-tree bindings.
The kbuild dependency script processor is enhanced to support processing
the dependency outputs from multiple separate commands at once.
The kbuild dtc rule is modified so that the C pre-processor is always
applied when compiling any device tree.
Some standard headers are created which define common constants for GPIO,
IRQ, and ARM GIC device tree bindings.

solution is to move some #include's out of #ifdef CONFIG_OF_DEVICE and use

schedule_mfi is supposed to be extracted from schedule(), and
is used in thread_saved_pc and get_wchan.
But, after optimization, schedule() is reduced to a sibling
call to __schedule(), and no real frame info can be extracted.
One solution is to compile schedule() with -fno-omit-frame-pointer
and -fno-optimize-sibling-calls, but that will incur performance
degradation.
Another solution is to extract info from the real scheduler,
__schedule, and this is the approache adopted here.
This patch reads the __schedule address by either following
the 'j' call in schedule if KALLSYMS is disabled or by using
kallsyms_lookup_name to lookup __schedule if KALLSYMS is
available, then, extracts schedule_mfi from __schedule frame info.
This patch also fixes the "Can't analyze schedule() prologue"
warning at boot time.

Given a function, get_frame_info() analyzes its instructions
to figure out frame size and return address. get_frame_info()
works as follows:
1. analyze up to 128 instructions if the function size is unknown
2. search for 'addiu/daddiu sp,sp,-immed' for frame size
3. search for 'sw ra,offset(sp)' for return address
4. end search when it sees jr/jal/jalr
This leads to an issue when the given function is a sibling
call, example shown as follows.
801ca110 <schedule>:
801ca110: 8f820000 lw v0,0(gp)
801ca114: 8c420000 lw v0,0(v0)
801ca118: 080726f0 j 801c9bc0 <__schedule>
801ca11c: 00000000 nop
801ca120 <io_schedule>:
801ca120: 27bdffe8 addiu sp,sp,-24
801ca124: 3c028022 lui v0,0x8022
801ca128: afbf0014 sw ra,20(sp)
In this case, get_frame_info() cannot properly detect schedule's
frame info, and eventually returns io_schedule's instead.
This patch adds 'j' to the end search condition to workaround
sibling call cases.

As reported:
This problem was discovered when doing BGP traffic with the TCP MD5 option
activated, where the following call chain caused a crash:
* tcp_v4_rcv
* tcp_v4_timewait_ack
* tcp_v4_send_ack -> follow stack variable rep.th
* tcp_v4_md5_hash_hdr
* tcp_md5_hash_header
* sg_init_one
* sg_set_buf
* virt_to_page
I noticed that tcp_v4_send_reset uses a similar stack variable and
also calls tcp_v4_md5_hash_hdr, so it has the same problem.
The networking core can indirectly call virt_to_phys() on stack
addresses, if this is done from PID 0, the stack will usually be in
CKSEG0, so virt_to_phys() needs to work there as well

This reverts commit d532f3d26716a39dfd4b88d687bd344fbe77e390.
The original commit has several problems:
1) Doesn't work with 64-bit kernels.
2) Calls TLBMISS_HANDLER_SETUP() before the code is generated.
3) Calls TLBMISS_HANDLER_SETUP() twice in per_cpu_trap_init() when
only one call is needed.
[ralf@linux-mips.org: Also revert the bits of the ASID patch which were
hidden in the KVM merge.]

The next revert depends on this one, so this has to go too.

As kmemleak now scans all module sections that are allocated, writable
and non executable, there's no need to scan individual sections that
might reference data.

Instead of just picking data sections by name (names that start
with .data, .bss or .ref.data), use the section flags and scan all
sections that are allocated, writable and not executable. Which should
cover all sections of a module that might reference data.

When we take an exception at EL1, we only want to enable debug
exceptions if we're not currently stepping, otherwise we can easily get
stuck in a loop stepping into interrupt handlers.
Unfortunately, the current code tests the wrong bit in the mdscr, so fix
that.

As per commit 764e0da1 (timers: Fixup the Kconfig consolidation
fallout), init/Kconfig already includes kernel/time/Kconfig, so no need
to do it explicitly for arm64.

The format of the lower 32-bits of the 64-bit operand to 'dc cisw' is
unchanged from ARMv7 architecture and the upper bits are RES0. This
implies that the 'way' field of the operand of 'dc cisw' occupies the
bit-positions [31 .. (32-A)]. Due to the use of 64-bit extended operands
to 'clz', the existing implementation of __flush_dcache_all is incorrectly
placing the 'way' field in the bit-positions [63 .. (64-A)].

The of_platform_populate() is currently invoked at device_initcall()
level. There are however drivers that use platform_driver_probe()
directly and they need the devices to be populated. This patch makes the
of_platform_populate() and arch_initcall().

During boot, we take the debug OS lock before interrupts are enabled.
This is required to prevent clearing of PSTATE.D on the interrupt entry
path, which could result in spurious debug exceptions before we've got
round to resetting things like the hardware breakpoints registers to a
sane state.
A problem with this approach is that taking the OS lock prevents an
external JTAG debugger from debugging the system, which is especially
irritating during boot, where JTAG debugging can be most useful.
This patch clears mdscr_el1 rather than taking the lock, clearing the
MDE and KDE bits and preventing self-hosted hardware debug exceptions
from occurring.

When compiling with allmodconfig. early_console is already defined as an
extern global pointer. Need let it point to the object which we intend
