 "Here are some small USB fixes for 4.11-rc5.

  The usual xhci fixes are here, as well as a fix for yet-another-bug-
  found-by-KASAN, those developers are doing great stuff here.

  And there's a phy build warning fix that showed up in 4.11-rc1.

  All of these have been in linux-next with no reported issues"

  reported bugs in some random serial drivers.

  I don't think these made the last linux-next due to me getting to them

  only affect drivers that the maintainers of sent me these patches for,

Pull ACPI fixes from Rafael Wysocki:
 "These fix two issues related to IOAPIC hotplug, an overzealous build
  optimization that prevents the function graph tracer from working with
  the ACPI subsystem correctly and an RCU synchronization issue in the
  ACPI APEI code.

  Specifics:

   - drop the unconditional setting of the '-Os' gcc flag from the ACPI
     Makefile to make the function graph tracer work correctly with the
     ACPI subsystem (Josh Poimboeuf).

   - add missing synchronize_rcu() to ghes_remove() which removes an
     element from an RCU-protected list, but fails to synchronize it
     properly afterward (James Morse).

   - fix two problems related to IOAPIC hotplug, a local variable
     initialization in setup_res() and the creation of platform device
     objects for IO(x)APICs which are (a) unused and (b) leaked on
     hot-removal (Joerg Roedel)"

Pull power management fixes from Rafael Wysocki:
 "These fix a cpufreq core issue with the initialization of the cpufreq
  sysfs interface and a cpuidle powernv driver initialization issue.

  Specifics:

   - symbolic links from CPU directories to the corresponding cpufreq
     policy directories in sysfs are not created during initialization
     in some cases which confuses user space, so prevent that from
     happening (Rafael Wysocki).

   - the powernv cpuidle driver fails to pass a correct cpumaks to the
     cpuidle core in some cases which causes subsequent failures to
     occur, so fix it (Vaidyanathan Srinivasan)"

The work-around for the Qualcomm Datacenter Technologies QDF2400
erratum 44 sets the "qdf2400_e44_present" global variable if the
work-around is needed.  However, this check does not happen until after
earlycon is initialized, which means the work-around is not
used, and the console hangs as soon as it displays one character.

kbuild test robot reported a non-static variable name collision between
a staging driver and a RapidIO driver, with a generic variable name of
'dbg_level'.

Both drivers should be changed so that they don't use this generic
public variable name.  This patch fixes the RapidIO driver but does not
change the user interface (name) for the module parameter.

Changes to hugetlbfs reservation maps is a two step process.  The first
step is a call to region_chg to determine what needs to be changed, and
prepare that change.  This should be followed by a call to call to
region_add to commit the change, or region_abort to abort the change.

The error path in hugetlb_reserve_pages called region_abort after a
failed call to region_chg.  As a result, the adds_in_progress counter in
the reservation map is off by 1.  This is caught by a VM_BUG_ON in
resv_map_release when the reservation map is freed.

syzkaller fuzzer (when using an injected kmalloc failure) found this
bug, that resulted in the following:

Disable kasan after the first report.  There are several reasons for
this:

 - Single bug quite often has multiple invalid memory accesses causing
   storm in the dmesg.

 - Write OOB access might corrupt metadata so the next report will print
   bogus alloc/free stacktraces.

 - Reports after the first easily could be not bugs by itself but just
   side effects of the first one.

Given that multiple reports usually only do harm, it makes sense to
disable kasan after the first one.  If user wants to see all the
reports, the boot-time parameter kasan_multi_shot must be used.

Any time after inode allocation, destroy_inode can be called.  The
hugetlbfs inode contains a shared_policy structure, and
mpol_free_shared_policy is unconditionally called as part of
hugetlbfs_destroy_inode.  Initialize the policy as part of inode
allocation so that any quick (error path) calls to destroy_inode will be
handed an initialized policy.

A section name for .data..ro_after_init was added by both:

    commit d07a980c ("s390: add proper __ro_after_init support")

and

    commit d7c19b06 ("mm: kmemleak: scan .data.ro_after_init")

The latter adds incorrect wrapping around the existing s390 section, and
came later.  I'd prefer the s390 naming, so this moves the s390-specific
name up to the asm-generic/sections.h and renames the section as used by
kmemleak (and in the future, kernel/extable.c).

This bug is triggered when pmd_present() returns true for non-present
hugetlb, so fixing the present check in follow_huge_pmd() prevents it.
Using pmd_present() to determine present/non-present for hugetlb is not
correct, because pmd_present() checks multiple bits (not only
_PAGE_PRESENT) for historical reason and it can misjudge hugetlb state.

Commit 0a6b76dd ("mm: workingset: make shadow node shrinker memcg
aware") enabled cgroup-awareness in the shadow node shrinker, but forgot
to also enable cgroup-awareness in the list_lru the shadow nodes sit on.

Consequently, all shadow nodes are sitting on a global (per-NUMA node)
list, while the shrinker applies the limits according to the amount of
cache in the cgroup its shrinking.  The result is excessive pressure on
the shadow nodes from cgroups that have very little cache.

Enable memcg-mode on the shadow node LRUs, such that per-cgroup limits
are applied to per-cgroup lists.

The problem is in the following lines:

    new = page - pvmw.page->index +
        linear_page_index(vma, pvmw.address);

The 'new' is calculated with 'page' which is given by the caller as a
destination page and some offset adjustment for thp.  But this doesn't
properly work for ksm pages because pvmw.page->index doesn't change for
each address but linear_page_index() changes, which means that 'new'
points to different pages for each addresses backed by the ksm page.  As
a result, we try to set totally unrelated pages as destination pages,
and that causes kernel crash.

This patch fixes the miscalculation and makes ksm page migration work
fine.

Commit 63d63cbf "NFSv4.1: Don't recheck delegations that
have already been checked" introduced a regression where when a
client received BAD_STATEID error it would not send any TEST_STATEID
and instead go into an infinite loop of resending the IO that caused
the BAD_STATEID.

In commit d0aeaa83 ("serial: exar:
split out the exar code from 8250_pci") the exar driver got its own
Kconfig.  However the text for the new option was never changed from
the original 8250_PCI text, and hence it appears confusing when you
get asked the same question twice:

  8250/16550 PCI device support (SERIAL_8250_PCI) [Y/n/m/?] (NEW)
    8250/16550 PCI device support (SERIAL_8250_EXAR) [Y/n/m] (NEW)

Adding to the confusion, is that there is no help text for this new
option to indicate it is specific to a certain family of cards.

Fix both issues at the same time, as well as the space vs. tab issues
introduced in the same commit.

A side effect of 89d82324 ("tty/serial: atmel_serial: BUG: stop DMA
from transmitting in stop_tx") is that the console can be called with
TX path disabled. Then the system would hang trying to push charecters
out in atmel_console_putchar().

If uart_flush_buffer() is called between atmel_tx_dma() and
atmel_complete_tx_dma(), the circular buffer has been cleared, but not
atmel_port->tx_len.
That leads to a circular buffer overflow (dumping (UART_XMIT_SIZE -
atmel_port->tx_len) bytes).

The reference manual for the i.MX28 recommends to calculate the divisor
as

	divisor = (UARTCLK * 32) / baud rate, rounded to the nearest integer

, so let's do this. For a typical setup of UARTCLK = 24 MHz and baud
rate = 115200 this changes the divisor from 6666 to 6667 and so the
actual baud rate improves from 115211.521 Bd (error ≅ 0.01 %) to
115194.240 Bd (error ≅ 0.005 %).

On this Dell AIO machine, the lineout jack does not work.

We found the pin 0x1a is assigned to lineout on this machine, and in
the past, we applied ALC298_FIXUP_DELL1_MIC_NO_PRESENCE to fix the
heaset-set mic problem for this machine, this fixup will redefine
the pin 0x1a to headphone-mic, as a result the lineout doesn't
work anymore.

After consulting with Dell, they told us this machine doesn't support
microphone via headset jack, so we add a new fixup which only defines
the pin 0x18 as the headset-mic.

[rearranged the fixup insertion position by tiwai in order to make the
 merge with other branches easier -- tiwai]
