SoC changes for omaps for v4.11 merge window. This adds support
for keeping the interconnect target module active for uart if
earlycon is specified. And we're adding Aaro Koskinen as a
co-maintainer for omap1 to make sure things stay working for
omap1. The other changes are mostly clean-up of old legacy code:

- Remove unused omap_display_init()
- Make omapdss_find_dss_of_node() function static
- Add support for earlycon
- Tidy up omap1 usb logging output with pr_cont
- Make omap_otg_init() static
- Delete redundant CPU class checks for omap1
- Remove unused mpurate cmdline option that has not done
  anything for past 1.5 years at least

The 'mpurate' option, historically used for specifying an initial
MPU rate at boot, no longer has any effect due to the supporting
code being removed as it was 'wrong and dangerous' [1].

This patch removes the remaining dead code associated with the
__setup macros to avoid confusion and reduce bloat.

Hwmod core tries to reset and idles each IP that is registered with hwmod.
In case of earlycon, that specific uart IP cannot be reset or keep it in
idle state else earlycon hangs once hwmod resets that uart IP. So add support
to not reset uart that is being used as earlycon only if CONFIG_SERIAL_EARLYCON
is enabled.

Several people report seeing warnings about inconsistent radix tree
nodes followed by crashes in the workingset code, which all looked like
use-after-free access from the shadow node shrinker.

Dave Jones managed to reproduce the issue with a debug patch applied,
which confirmed that the radix tree shrinking indeed frees shadow nodes
while they are still linked to the shadow LRU:

  WARNING: CPU: 2 PID: 53 at lib/radix-tree.c:643 delete_node+0x1e4/0x200
  CPU: 2 PID: 53 Comm: kswapd0 Not tainted 4.10.0-rc2-think+ #3
  Call Trace:

     __radix_tree_delete_node+0xd/0x10
     shadow_lru_isolate+0xe6/0x220

     shrink_node+0x22c/0x330
     kswapd+0x392/0x8f0

This is the WARN_ON_ONCE(!list_empty(&node->private_list)) placed in the
inlined radix_tree_shrink().

The problem is with 14b46879 ("mm: workingset: move shadow entry
tracking to radix tree exceptional tracking"), which passes an update
callback into the radix tree to link and unlink shadow leaf nodes when
tree entries change, but forgot to pass the callback when reclaiming a
shadow node.

While the reclaimed shadow node itself is unlinked by the shrinker, its
deletion from the tree can cause the left-most leaf node in the tree to
be shrunk.  If that happens to be a shadow node as well, we don't unlink
it from the LRU as we should.

Consider this tree, where the s are shadow entries:

       root->rnode
            |
       [0       n]
        |       |
     [s    ] [sssss]

Now the shadow node shrinker reclaims the rightmost leaf node through
the shadow node LRU:

       root->rnode
            |
       [0        ]
        |
    [s     ]

Because the parent of the deleted node is the first level below the
root and has only one child in the left-most slot, the intermediate
level is shrunk and the node containing the single shadow is put in
its place:

       root->rnode
            |
       [s        ]

The shrinker again sees a single left-most slot in a first level node
and thus decides to store the shadow in root->rnode directly and free
the node - which is a leaf node on the shadow node LRU.

  root->rnode
       |
       s

Without the update callback, the freed node remains on the shadow LRU,
where it causes later shrinker runs to crash.

Pass the node updater callback into __radix_tree_delete_node() in case
the deletion causes the left-most branch in the tree to collapse too.

Also add warnings when linked nodes are freed right away, rather than
wait for the use-after-free when the list is scanned much later.

4.10-rc loadtest (even on x86, and even without THPCache) fails with
"fork: Cannot allocate memory" or some such; and /proc/meminfo shows
PageTables growing.

Commit 953c66c2 ("mm: THP page cache support for ppc64") that got
merged in rc1 removed the freeing of an unused preallocated pagetable
after do_fault_around() has called map_pages().

This is usually a good optimization, so that the followup doesn't have
to reallocate one; but it's not sufficient to shift the freeing into
alloc_set_pte(), since there are failure cases (most commonly
VM_FAULT_RETRY) which never reach finish_fault().

Check and free it at the outer level in do_fault(), then we don't need
to worry in alloc_set_pte(), and can restore that to how it was (I
cannot find any reason to pte_free() under lock as it was doing).

And fix a separate pagetable leak, or crash, introduced by the same
change, that could only show up on some ppc64: why does do_set_pmd()'s
failure case attempt to withdraw a pagetable when it never deposited
one, at the same time overwriting (so leaking) the vmf->prealloc_pte?
Residue of an earlier implementation, perhaps? Delete it.

Pull power management fixes from Rafael Wysocki:
 "These fix a few issues in the intel_pstate driver, a documetation
  issue, a false-positive compiler warning in the generic power domains
  framework and two problems in the devfreq subsystem. They also update
  the MAINTAINERS entry for devfreq and add a new "compatible" string to
  the generic cpufreq-dt driver.

  Specifics:

   - Fix a few intel_pstate driver issues: add missing locking it two
     places, avoid exposing a useless debugfs interface and keep the
     attribute values in sysfs in sync (Rafael Wysocki).

   - Drop confusing kernel-doc references related to power management
     and ACPI from the driver API manual (Rafael Wysocki).

   - Make a false-positive compiler warning in the generic power domains
     framework go away (Augusto Mecking Caringi).

   - Fix two initialization issues in the devfreq subsystem and update
     the MAINTAINERS entry for it (Chanwoo Choi).

   - Add a new "compatible" string for APM X-Gene 2 to the generic DT
     cpufreq driver (Hoan Tran)"

  cpufreq: dt: Add support for APM X-Gene 2

So they can figure out what is the optimal number of pages
that can be contingously stitched together without fear of
bounce buffer.

We also expose an mechanism for sub-users of SWIOTLB API, such
as Xen-SWIOTLB to set the max segment value. And lastly
if swiotlb=force is set (which mandates we bounce buffer everything)
we set max_segment so at least we can bounce buffer one 4K page
instead of a giant 512KB one for which we may not have space.

Aaro has been doing a great job making sure mach-omap1 stays working
with the mainline kernel. So let's add Aaro as omap1 co-maintainer to
the MAINTAINERS file.
