Copy u-boot's FDT address translation code from common/fdt_support. This
code was originally based on the kernel's unflattened DT address parsing
code.

This commit can be reverted once relicensing of this code to GPLv2/BSD
is done and it is added to libfdt.

Use for_each_matching_node_and_match instead of for_each_matching_node plus
of_match_node to avoid searching the DT twice for each node.

The sunxi DT scanning code should really be re-worked rather than have
its own private matching infrastructure. It is working around needing a
function pointer and a data pointer for each compatible match.

of_can_translate_address only checks some conditions for address
translation, but does not check other conditions like having range
properties. The checks it does do are redundant with
__of_address_translate. The only difference is printing a message or
not. Since we only have a single caller that does the full translation
anyway, just remove of_can_translate_address and quiet the error
message.

Using non-translatable addresses in platform device names is wrong
because they may not be globally unique. Just use the default naming with
a global index if the address cannot be translated instead.

of_can_translate_address has the same checks as of_translate_address, so
we can remove it here as well.

Pull x86 fixes from Peter Anvin:
 "A somewhat unpleasantly large collection of small fixes.  The big ones
  are the __visible tree sweep and a fix for 'earlyprintk=efi,keep'.  It
  was using __init functions with predictably suboptimal results.

  Another key fix is a build fix which would produce output that simply
  would not decompress correctly in some configuration, due to the
  existing Makefiles picking up an unfortunate local label and mistaking
  it for the global symbol _end.

  Additional fixes include the handling of 64-bit numbers when setting
  the vdso data page (a latent bug which became manifest when i386
  started exporting a vdso with time functions), a fix to the new MSR
  manipulation accessors which would cause features to not get properly
  unblocked, a build fix for 32-bit userland, and a few new platform
  quirks"

* 'x86-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip:
  x86, vdso, time: Cast tv_nsec to u64 for proper shifting in update_vsyscall()
  x86: Fix typo in MSR_IA32_MISC_ENABLE_LIMIT_CPUID macro
  x86: Fix typo preventing msr_set/clear_bit from having an effect

  x86, build: Don't get confused by local symbols
  x86/efi: earlyprintk=efi,keep fix

With tk->wall_to_monotonic.tv_nsec being a 32-bit value on 32-bit
systems, (tk->wall_to_monotonic.tv_nsec << tk->shift) in update_vsyscall()
may lose upper bits or, worse, add them since compiler will do this:
	(u64)(tk->wall_to_monotonic.tv_nsec << tk->shift)
instead of
	((u64)tk->wall_to_monotonic.tv_nsec << tk->shift)

So if, for example, tv_nsec is 0x800000 and shift is 8 we will end up
with 0xffffffff80000000 instead of 0x80000000. And then we are stuck in
the subsequent 'while' loop.

We need an explicit cast.

Commit de7b2973 "tracepoint: Use struct pointer instead of name hash
for reg/unreg tracepoints" introduces a use after free by calling
release_probes on the old struct tracepoint array before the newly
allocated array is published with rcu_assign_pointer. There is a race
window where tracepoints (RCU readers) can perform a
"use-after-grace-period-after-free", which shows up as a GPF in
stress-tests.

The replacement of the 'count' variable by two variables 'incs' and
'decs' to resolve some race conditions during module unloading was done
in parallel with some cleanup in the trace subsystem, and was integrated
as a merge.

Unfortunately, the formula for this replacement was wrong in the tracing
code, and the refcount in the traces was not usable as a result.

Use 'count = incs - decs' to compute the user count.

This reverts commit c42deffd.

commit <mmc: rtsx: add support for pre_req and post_req> did use
mutex_unlock() in tasklet, but mutex_unlock() can't be used in
tasklet(atomic context). The driver needs to use mutex to avoid
concurrency, so we can't use tasklet here, the patch need to be
removed.

The spinlock host->lock and pcr->lock may deadlock, one way to solve
the deadlock is remove host->lock in sd_isr_done_transfer(), but if
using workqueue the we can avoid using the spinlock and also avoid
the problem.

If you are using a 64-bit kernel with 32-bit userland, then
scripts/gcc-x86_64-has-stack-protector.sh invokes 32-bit gcc
with -mcmodel=kernel, which produces:

<stdin>:1:0: error: code model 'kernel' not supported in the 32 bit mode

and trips the "broken compiler" test at arch/x86/Makefile:120.

There are several places a fix is possible, but the following seems
cleanest.  (But it's minimal; it would also be possible to factor
out a bunch of stuff from the two branches of the if.)
