Pull char / misc patches from Greg KH:
"Here's the big char/misc driver update for 3.20-rc1.
Lots of little things in here, all described in the changelog.
Nothing major or unusual, except maybe the binder selinux stuff, which
was all acked by the proper selinux people and they thought it best to
come through this tree.
All of this has been in linux-next with no reported issues for a while"

Function etm_writel_cp14() takes an offset and a value rather
than the other way around, something this patch is correcting.
The semantic remains the same since it is only a function stub.

The CoreSight ETM/PTM driver contains a check for a
CONFIG_CORESIGHT_SOURCE_ETM_DEFAULT_ENABLE macro. But there's no related
Kconfig symbol CORESIGHT_SOURCE_ETM_DEFAULT_ENABLE. Remove that check
and the single line of code it hides.

validate if it match the newly added device. If it does not match,
only then should the @still_orphan flag should be set.

If a MCB PCI Carrier device is IO mapped insted of memory-mapped (which is
currently unsupported by the upstream driver) the probe function bails out
with -ENOTSUPP.
In this case the memory of the PCI device was not unmapped.

The big issue here is:
of_property_read_u32(np, "flow_cntrl", (u32 *)&dt_pdata->flow_cntrl);
"->flow_cntrl" is a char so when we write a 32 bit number to it then it
corrupts past the end of the char. It's probably hard to notice because
the struct has padding so the code works on little endian systems. But
on a big endian system the code would fail and on a 64 bit, big endian
systems then "nshutdown_gpio" and "baud_rate" would be buggy as well.

We might enter the interrupt handler with hw_ready already set,
but prior we actually started the reset flow.
To soleve this we move the reset release from the interrupt handler
to the HW start wait function which is part of the reset sequence.

Commit 4b2f9abea52a ("staging: hv: convert channel_mgmt.c to not call
osd_schedule_callback")' was written under an assumption that we never receive
Rescind offer while we're still processing the initial Offer request. However,
the issue we fixed in 04a258c162a8 could be caused by this assumption not
always being true.
In particular, we need to protect against the following:
1) Receiving a Rescind offer after we do queue_work() for processing an Offer
request and before we actually enter vmbus_process_offer(). work.func points
to vmbus_process_offer() at this moment and in vmbus_onoffer_rescind() we do
another queue_work() without a check so we'll enter vmbus_process_offer()
twice.
2) Receiving a Rescind offer after we enter vmbus_process_offer() and
especially after we set >state = CHANNEL_OPEN_STATE. Many things can go
wrong in that case, e.g. we can call free_channel() while we're still using
it.
Implement the required protection by changing work->func at the very end of
vmbus_process_offer() and checking work->func in vmbus_onoffer_rescind(). In
case we receive rescind offer during or before vmbus_process_offer() is done
we set rescind flag to true and we check it at the end of vmbus_process_offer()
so such offer will not get lost.

(this is a resend of this patch. Originally sent last year, but post
appears to have been lost)
This change fixes two bugs in the VMCI host driver related to mapping
the notify boolean from user space into kernel space:
- the actual UVA was rounded up to the next page boundary - resulting
in memory corruption in the calling process whenever notifications
would be signalled. This has been fixed by just removing the
PAGE_ALIGN part, since get_user_pages_fast can figure this out on
its own
- the mapped page wasn't stored anywhere, so it wasn't unmapped and
put back when a VMCI context was destroyed. Fixed this by
remembering the page.

if(!wait_for_completion_interruptible_timeout(...))
only handles the timeout case - this patch adds handling the
signal case the same as timeout.
Only the timeout case was being handled, the signal case
(-ERESTARTSYS) was treated just like the case of successful
completion, which is most likely not reasonable.
read_local_version() is called from download_firmware() where
it checks for !=0 return, so the error handling logic should be
preserved correctly.

This patch adds labels support for fans if SMM function with EAX register
0x03a3 reports it. This information was taken from DOS binary NBSVC.MDM.
Additionally this patch change detection of fan presece. Instead reading fan
status now detection is based on new label SMM function. Dell DOS binary
NBSVC.MDM is doing similar checks, so we should do that too.
This patch also remove I8K_FAN_LEFT and I8K_FAN_RIGHT usage from hwmon driver
part because that names does not make sense anymore. So numeric constants are
used instead. Original /proc/i8k ioctl part was not changed for compatibility
reasons.

Both Dell Latitude machines were tested with new fan autodetection code and they
are working fine. We already have DMI_MATCH data for generic Latitude machines
which match also E6440 and E6540 models. So we do not need to maintain DMI data
for those specific machines anymore.

This patch adds new function i8k_get_fan_nominal_speed() for doing SMM call
which will return nominal fan RPM for specified fan speed. It returns nominal
RPM value at which fan operate when speed (0, 1, 2, 3) is set. It looks like
RPM value is not accurate, but still provides very useful information.
New function i8k_get_fan_nominal_speed() is used for determinate if fan
multiplier is 1 or 30. If function for maximal fan value success and returned
RPM value too high (above 30000) then fan multiplier is set to 1. Otherwise
multiplier is not changed and default value 30 is used.

Instead of returning a previous value if the SMM code returns
an error when trying to read a temperature, retry once.
If that fails again, return -ENODATA. Also return -ENODATA if an
attempt is made to read the GPU temperature but the GPU is
currently turned off.
Drop the I8K_TEMPERATURE_BUG definition and handle the related bug
unconditionally.

Guenter Roeck suggested to return -ENODATA instead -ERANGE or -EINVAL when BIOS
reports invalid temperature value.

Detect presense of sensor by calling type function instead trying to read
temperature value. Type function is working also for sensors which are temporary
turned off (e.g on GPU which is turned off). Dell DOS binary NBSVC.MDM is doing
similar checks, so we should do that too.

This patch adds labels for temperature sensors if SMM function with EAX register
0x11a3 reports it. This information was taken from DOS binary NBSVC.MDM.

need to down the semaphore, otherwise, after the daemon starts next
time, the obsolete data in fcopy_transaction.message or
fcopy_transaction.fcopy_msg will be used immediately.

Currently, the API for sending a multi-page buffer over VMBUS is limited to
a maximum pfn array of MAX_MULTIPAGE_BUFFER_COUNT. This limitation is
not imposed by the host and unnecessarily limits the maximum payload
that can be sent. Implement an API that does not have this restriction.

We currently release memory (balloon down) in the interrupt context and we also
post memory status while releasing memory. Rather than posting the status
in the interrupt context, wakeup the status posting thread to post the status.

We support memory hot-add in the Hyper-V balloon driver by hot adding an appropriately
sized and aligned region and controlling the on-lining of pages within that region
based on the pages that the host wants us to online. We do this because the
granularity and alignment requirements in Linux are different from what Windows
expects. The state to manage the onlining of pages needs to be correctly
protected. Fix this bug.

Make adjustments in computing the balloon floor. The current computation
of the balloon floor was not appropriate for virtual machines with more than
10 GB of assigned memory - we would get into situations where the host would
agressively balloon down the guest and leave the guest in an unusable state.
This patch fixes the issue by raising the floor.

fwrite() does not actually return the number of bytes written and
this value is being ignored anyway and ferror() is being called to
check for an error. As we assign to this variable and never use it
we get the following compile-time warning:
hv_kvp_daemon.c:149:9: warning: variable .bytes_written. set but not used [-Wunused-but-set-variable]
Remove bytes_written completely.

Add security hooks to the binder and implement the hooks for SELinux.
The security hooks enable security modules such as SELinux to implement
controls over binder IPC. The security hooks include support for
controlling what process can become the binder context manager
(binder_set_context_mgr), controlling the ability of a process
to invoke a binder transaction/IPC to another process (binder_transaction),
controlling the ability of a process to transfer a binder reference to
another process (binder_transfer_binder), and controlling the ability
of a process to transfer an open file to another process (binder_transfer_file).
These hooks have been included in the Android kernel trees since Android 4.3.
(Updated to reflect upstream relocation and changes to the binder driver,
changes to the LSM audit data structures, coding style cleanups, and
to add inline documentation for the hooks).
