drm/bridge/sii8620: initial support for eCBUS-S mode

The Single-ended eCBUS Mode (eCBUS-S) mode provides 60 Mb/s full-duplex
bidirectional traffic for three channels:
- CBUS data (CBUS1 channel),
- High-bandwidth MHL data (eMSC channel),
- tunneling data (T-CBUS channel).
It is required to fully support MHL3 dongles.

drm/bridge/sii8620: add continuations to messages

Due to asynchronous nature of MHL flow of execution is dispersed. Logical
continuation of some actions happens after response of peer, i.e in interrupt
handler. To simplify coding continuation mechanism has been added - it is now
possible to provide continuation callback, which will be called after peer
responds to given action.

Smack: ignore private inode for file functions

The access to fd from anon_inode is always failed because there is
no set xattr operations. So this patch fixes to ignore private
inode including anon_inode for file functions.

It was only ignored for smack_file_receive() to share dma-buf fd,
but dma-buf has other functions like ioctl and mmap.

packet: fix race condition in packet_set_ring

When packet_set_ring creates a ring buffer it will initialize a
struct timer_list if the packet version is TPACKET_V3. This value
can then be raced by a different thread calling setsockopt to
set the version to TPACKET_V1 before packet_set_ring has finished.

This leads to a use-after-free on a function pointer in the
struct timer_list when the socket is closed as the previously
initialized timer will not be deleted.

The bug is fixed by taking lock_sock(sk) in packet_setsockopt when
changing the packet version while also taking the lock at the start
of packet_set_ring.

Ps. This is CVE-2016-8655 patch,

kdbus: retrieve SECLABEL anew on each CONN_INFO (efl/launchpad developers' request)

Tizen code routinely performs the following operation sequence:
1. create kdbus connection
2. update seclabel
3. rely on updated seclabel

CONN_INFO has always returned seclabel collected at HELLO time (behavior
consistent across all kdbus versions and documented in kdbus man). This
would break step 3 of the above sequence.

In sync call situation, kdbus_conn_reply() calls kdbus_reply_unlink(reply).

so it is called twice. Even it has no problems because kdbus_reply_unlink()

Bluetooth: Fix IRK distribution issue when Privacy is disabled

The devices, like Android 6.x, which don't support privacy 1.2
couldn't make BLE connection to the device which doesn't distribute
IRK when pairing because they use use wrong address type.
For compatibility, it needs to distribute IRK even though Privacy
feature is disabled. So setting IRK interface is added and BlueZ
will set IRK if privacy feature is disabled. And when BLE pairing,
IRK will be always distributed.

drm/exynos/hdmi: Don't print error on deferral due to regulators

the kernel log and confuse users.

drm/bridge/sii8620: stop using macros having NULL values

Many VAL_* macros represent single unset bit, ie their value is 0.
These macros are confusing and obfuscates the code.
The patch removes all uses of such macros, and replaces all
uses of single-set-bit VAL_* macros with their BIT_* equivalent.
Beside cleaning it makes the driver closer to the mainline.

drm/exynos: fix error handling in exynos_drm_subdrv_open

gcc-6 warns about a pointless loop in exynos_drm_subdrv_open:

drivers/gpu/drm/exynos/exynos_drm_core.c: In function 'exynos_drm_subdrv_open':
drivers/gpu/drm/exynos/exynos_drm_core.c:104:199: error: self-comparison always evaluates to false [-Werror=tautological-compare]
list_for_each_entry_reverse(subdrv, &subdrv->list, list) {

Here, the list_for_each_entry_reverse immediately terminates because
the subdrv pointer is compared to itself as the loop end condition.

If we were to take the current subdrv pointer as the start of the
list (as we would do if list_for_each_entry_reverse() was not a macro),
we would iterate backwards over the &exynos_drm_subdrv_list anchor,
which would be even worse.

Instead, we need to use list_for_each_entry_continue_reverse()
to go back over each subdrv that was successfully opened until
the first entry.

mm: remove gup_flags FOLL_WRITE games from __get_user_pages()

[ Upstream commit 19be0eaffa3ac7d8eb6784ad9bdbc7d67ed8e619 ]

This is an ancient bug that was actually attempted to be fixed once
(badly) by me eleven years ago in commit 4ceb5db9757a ("Fix
get_user_pages() race for write access") but that was then undone due to
problems on s390 by commit f33ea7f404e5 ("fix get_user_pages bug").

In the meantime, the s390 situation has long been fixed, and we can now
fix it by checking the pte_dirty() bit properly (and do it better). The
s390 dirty bit was implemented in abf09bed3cce ("s390/mm: implement
software dirty bits") which made it into v3.9. Earlier kernels will
have to look at the page state itself.

Also, the VM has become more scalable, and what used a purely
theoretical race back then has become easier to trigger.

To fix it, we introduce a new internal FOLL_COW flag to mark the "yes,
we already did a COW" rather than play racy games with FOLL_WRITE that
is very fundamental, and then use the pte dirty flag to validate that
the FOLL_COW flag is still valid.

Revert "Fix for enabling self-broadcast-signal subscription"

This reverts commit 8ebcf6b29cbc2838841b4eb5875a59c70f187b68.

Original fix is no longer needed - proper one has been applied
to systemd, which now does not forward broadcasts to itself
when kdbus is used.

Reference: https://github.com/systemd/systemd/commit/0a069ce62de904ae9cbaf23d026ac380b02e50e4

    core: harden cgroups-agent forwarding
    Author: David Herrmann <dh.herrmann@gmail.com>

    Furthermore, never forward broadcasts we sent ourself. This might happen
    on kdbus, as we forward the message on the same bus we received it on,
    thus ending up in an endless loop.

ASoC: max98090: fix interrupt handling problem

The max98090_interrupt handler currently will read the device status
register. After that, it will act only when the JDET bit is set.
However, when max98090_interrupt handler is triggered and jack status
register has really changed, the JDET bit of device status register
is not set as expected for unknown reason. Because of this, the jack status cannot be reported.

This patch adds a workaround solution for jack detection, by adding
the second chance to recognize the reason of interrupt generation.
If the interrupt is generated without setting any values on device
status register, jack status register is compared to the current jack
states. If the jack status is changed, the JDET bit is manually set.
