DP/DM linestate is needed by the QUSB2 PHY driver to configure the
polarity of DP/DM transition triggers for exiting low power mode.
This was previously available via the QUSB2PHY_PORT_UTMI_STATUS
PHY register which is now deprecated. In order to correctly determine
the interrupt polarity we need to pass the current operating speed
to the QUSB2 PHY driver. The PHY driver uses mode, speed and
cable connection status to determine the linestate and configure
interrupt polarities for wake up. Add logic to determine operating
speed for host and device mode cases.

Add APIs to send and receive vendor defined messages (VDM) over
USB PD. A handler for a standard or vendor ID (SVID) can register
callbacks to be notified of reception of VDM messages. One
use case is for another kernel driver, such as DisplayPort, to be
able to be notified when an Alternate Mode adapter is connected
to the Type-C port in order to enter modal operation. SVID
handlers should maintain their own state and timer resources
in order to comply with the Power Delivery Specification.

Currently power supply name is passed to get the battery profile
in of_batterydata_get_best_profile(). This creates a dependency
of waiting for the driver that has the power supply class device.
Improve this by passing the battery id directly to the API. This
way, getting battery id will be the responsibility of caller.

If target can support multiple codecs, only one of the
codecs will be enumerated. Do not clean up common resources
when other codec fails to enumerate.

The new API clk_set_flags could be used by hardware specific clock drivers
or clients for specific hardware requirements. These flags could be custom
defined as per hardware needs.

commit 90d0f0f11588ec692c12f9009089b398be395184 upstream.
For !BIO_CLONED bio, we can use .bi_vcnt safely, but it
doesn't mean we can just simply return .bi_io_vec[.bi_vcnt - 1]
because the start postion may have been moved in the middle of
the bvec, such as splitting in the middle of bvec.
Fixes: 7bcd79ac50d9(block: bio: introduce helpers to get the 1st and last bvec)

commit dc17147de328a74bbdee67c1bf37d2f1992de756 upstream.
Commit f37755490fe9b ("tracepoints: Do not trace when cpu is offline") added
a check to make sure that tracepoints only get called when the cpu is
online, as it uses rcu_read_lock_sched() for protection.
Commit 3a630178fd5f3 ("tracing: generate RCU warnings even when tracepoints
are disabled") added lockdep checks (including rcu checks) for events that
are not enabled to catch possible RCU issues that would only be triggered if
a trace event was enabled. Commit f37755490fe9b only stopped the warnings
when the trace event was enabled but did not prevent warnings if the trace
event was called when disabled.
To fix this, the cpu online check is moved to where the condition is added
to the trace event. This will place the cpu online check in all places that
it may be used now and in the future.

commit 8244062ef1e54502ef55f54cced659913f244c3e upstream.
For CONFIG_KALLSYMS, we keep two symbol tables and two string tables.
There's one full copy, marked SHF_ALLOC and laid out at the end of the
module's init section. There's also a cut-down version that only
contains core symbols and strings, and lives in the module's core
section.
After module init (and before we free the module memory), we switch
the mod->symtab, mod->num_symtab and mod->strtab to point to the core
versions. We do this under the module_mutex.
However, kallsyms doesn't take the module_mutex: it uses
preempt_disable() and rcu tricks to walk through the modules, because
it's used in the oops path. It's also used in /proc/kallsyms.
There's nothing atomic about the change of these variables, so we can
get the old (larger!) num_symtab and the new symtab pointer; in fact
this is what I saw when trying to reproduce.
By grouping these variables together, we can use a
carefully-dereferenced pointer to ensure we always get one or the
other (the free of the module init section is already done in an RCU
callback, so that's safe). We allocate the init one at the end of the
module init section, and keep the core one inside the struct module
itself (it could also have been allocated at the end of the module
core, but that's probably overkill).
[ Rebased for 4.4-stable and older, because the following changes aren't
in the older trees:
- e0224418516b4d8a6c2160574bac18447c354ef0: adds arg to is_core_symbol
- 7523e4dc5057e157212b4741abd6256e03404cf1: module_init/module_core/init_size/core_size
become init_layout.base/core_layout.base/init_layout.size/core_layout.size.

commit 25e71a99f10e444cd00bb2ebccb11e1c9fb672b1 upstream.
This patch applies the two introduced helpers to
figure out the 1st and last bvec, and fixes the
original way after bio splitting.

commit e0af29171aa8912e1ca95023b75ef336cd70d661 upstream.
In the following patch, the way for figuring out
the last bvec will be changed with a bit cost introduced,
so return immediately if the queue doesn't have virt
boundary limit. Actually most of devices have not
this limit.

commit e57cbaf0eb006eaa207395f3bfd7ce52c1b5539c upstream.
Commit 9f61668073a8d "tracing: Allow triggers to filter for CPU ids and
process names" added a 'comm' filter that will filter events based on the
current tasks struct 'comm'. But this now hides the ability to filter events
that have a 'comm' field too. For example, sched_migrate_task trace event.
That has a 'comm' field of the task to be migrated.
echo 'comm == "bash"' > events/sched_migrate_task/filter
will now filter all sched_migrate_task events for tasks named "bash" that
migrates other tasks (in interrupt context), instead of seeing when "bash"
itself gets migrated.
This fix requires a couple of changes.
1) Change the look up order for filter predicates to look at the events
fields before looking at the generic filters.
2) Instead of basing the filter function off of the "comm" name, have the
generic "comm" filter have its own filter_type (FILTER_COMM). Test
against the type instead of the name to assign the filter function.
3) Add a new "COMM" filter that works just like "comm" but will filter based
on the current task, even if the trace event contains a "comm" field.
Do the same for "cpu" field, adding a FILTER_CPU and a filter "CPU".

commit a1a0e23e49037c23ea84bc8cc146a03584d13577 upstream.
If cgroup writeback is in use, inodes can be scheduled for
asynchronous wb switching. Before 5ff8eaac1636 ("writeback: keep
superblock pinned during cgroup writeback association switches"), this
could race with umount leading to super_block being destroyed while
inodes are pinned for wb switching. 5ff8eaac1636 fixed it by bumping
s_active while wb switches are in flight; however, this allowed
in-flight wb switches to make umounts asynchronous when the userland
expected synchronosity - e.g. fsck immediately following umount may
fail because the device is still busy.
This patch removes the problematic super_block pinning and instead
makes generic_shutdown_super() flush in-flight wb switches. wb
switches are now executed on a dedicated isw_wq so that they can be
flushed and isw_nr_in_flight keeps track of the number of in-flight wb
switches so that flushing can be avoided in most cases.
v2: Move cgroup_writeback_umount() further below and add MS_ACTIVE
check in inode_switch_wbs() as Jan an Al suggested.

commit 7bcd79ac50d9d83350a835bdb91c04ac9e098412 upstream.
The bio passed to bio_will_gap() may be fast cloned from upper
layer(dm, md, bcache, fs, ...), or from bio splitting in block
core.
Unfortunately bio_will_gap() just figures out the last bvec via
'bi_io_vec[prev->bi_vcnt - 1]' directly, and this way is obviously
wrong.
This patch introduces two helpers for getting the first and last
bvec of one bio for fixing the issue.

commit 4ee34ea3a12396f35b26d90a094c75db95080baa upstream.
The id buffer in ata_device is a DMA target, but it isn't explicitly
cacheline aligned. Due to this, adjacent fields can be overwritten with
stale data from memory on non coherent architectures. As a result, the
kernel is sometimes unable to communicate with an ATA device.
Fix this by ensuring that the id buffer is cacheline aligned.
This issue is similar to that fixed by Commit 84bda12af31f
("libata: align ap->sector_buf").

commit 287e6611ab1eac76c2c5ebf6e345e04c80ca9c61 upstream.
As reported by Soohoon Lee, the HDIO_GET_32BIT ioctl does not
work correctly in compat mode with libata.
I have investigated the issue further and found multiple problems
that all appeared with the same commit that originally introduced
HDIO_GET_32BIT handling in libata back in linux-2.6.8 and presumably
also linux-2.4, as the code uses "copy_to_user(arg, &val, 1)" to copy
a 'long' variable containing either 0 or 1 to user space.
The problems with this are:
* On big-endian machines, this will always write a zero because it
stores the wrong byte into user space.
* In compat mode, the upper three bytes of the variable are updated
by the compat_hdio_ioctl() function, but they now contain
uninitialized stack data.
* The hdparm tool calling this ioctl uses a 'static long' variable
to store the result. This means at least the upper bytes are
initialized to zero, but calling another ioctl like HDIO_GET_MULTCOUNT
would fill them with data that remains stale when the low byte
is overwritten. Fortunately libata doesn't implement any of the
affected ioctl commands, so this would only happen when we query
both an IDE and an ATA device in the same command such as
"hdparm -N -c /dev/hda /dev/sda"
* The libata code for unknown reasons started using ATA_IOC_GET_IO32
and ATA_IOC_SET_IO32 as aliases for HDIO_GET_32BIT and HDIO_SET_32BIT,
while the ioctl commands that were added later use the normal
HDIO_* names. This is harmless but rather confusing.
This addresses all four issues by changing the code to use put_user()
on an 'unsigned long' variable in HDIO_GET_32BIT, like the IDE subsystem
does, and by clarifying the names of the ioctl commands.

commit aa226ff4a1ce79f229c6b7a4c0a14e17fececd01 upstream.
There are three subsystem callbacks in css shutdown path -
css_offline(), css_released() and css_free(). Except for
css_released(), cgroup core didn't guarantee the order of invocation.
css_offline() or css_free() could be called on a parent css before its
children. This behavior is unexpected and led to bugs in cpu and
memory controller.
This patch updates offline path so that a parent css is never offlined
before its children. Each css keeps online_cnt which reaches zero iff
itself and all its children are offline and offline_css() is invoked
only after online_cnt reaches zero.
This fixes the memory controller bug and allows the fix for cpu
controller.

commit e93ad19d05648397ef3bcb838d26aec06c245dc0 upstream.
If "cpuset.memory_migrate" is set, when a process is moved from one
cpuset to another with a different memory node mask, pages in used by
the process are migrated to the new set of nodes. This was performed
synchronously in the ->attach() callback, which is synchronized
against process management. Recently, the synchronization was changed
from per-process rwsem to global percpu rwsem for simplicity and
optimization.
Combined with the synchronous mm migration, this led to deadlocks
because mm migration could schedule a work item which may in turn try
to create a new worker blocking on the process management lock held
from cgroup process migration path.
This heavy an operation shouldn't be performed synchronously from that
deep inside cgroup migration in the first place. This patch punts the
actual migration to an ordered workqueue and updates cgroup process
migration and cpuset config update paths to flush the workqueue after
all locks are released. This way, the operations still seem
synchronous to userland without entangling mm migration with process
management synchronization. CPU hotplug can also invoke mm migration
but there's no reason for it to wait for mm migrations and thus
doesn't synchronize against their completions.

commit 67645d7619738e51c668ca69f097cb90b5470422 upstream.
There are a number of problems with revoking a "was sending" message:
(1) We never make any attempt to revoke data - only kvecs contibute to
con->out_skip. However, once the header (envelope) is written to the
socket, our peer learns data_len and sets itself to expect at least
data_len bytes to follow front or front+middle. If ceph_msg_revoke()
is called while the messenger is sending message's data portion,
anything we send after that call is counted by the OSD towards the now
revoked message's data portion. The effects vary, the most common one
is the eventual hang - higher layers get stuck waiting for the reply to
the message that was sent out after ceph_msg_revoke() returned and
treated by the OSD as a bunch of data bytes. This is what Matt ran
into.
(2) Flat out zeroing con->out_kvec_bytes worth of bytes to handle kvecs
is wrong. If ceph_msg_revoke() is called before the tag is sent out or
while the messenger is sending the header, we will get a connection
reset, either due to a bad tag (0 is not a valid tag) or a bad header
CRC, which kind of defeats the purpose of revoke. Currently the kernel
client refuses to work with header CRCs disabled, but that will likely
change in the future, making this even worse.
(3) con->out_skip is not reset on connection reset, leading to one or
more spurious connection resets if we happen to get a real one between
con->out_skip is set in ceph_msg_revoke() and before it's cleared in
write_partial_skip().
Fixing (1) and (3) is trivial. The idea behind fixing (2) is to never
zero the tag or the header, i.e. send out tag+header regardless of when
ceph_msg_revoke() is called. That way the header is always correct, no
unnecessary resets are induced and revoke stands ready for disabled
CRCs. Since ceph_msg_revoke() rips out con->out_msg, introduce a new
"message out temp" and copy the header into it before sending.

This fixes a problem that the system is cool, while the fan devices
are left running on full speed after boot, if fan device is registered
after thermal zone device.

commit bb431ba26c5cd0a17c941ca6c3a195a3a6d5d461 upstream.
After thermal zone device registered, as we have not read any
temperature before, thus tz->temperature should not be 0,
which actually means 0C, and thermal trend is not available.
In this case, we need specially handling for the first
thermal_zone_device_update().
Both thermal core framework and step_wise governor is
enhanced to handle this. And since the step_wise governor
is the only one that uses trends, so it's the only thermal
governor that needs to be updated.

commit 8599846d73997cdbccf63f23394d871cfad1e5e6 upstream.
Currently we have two policies for deciding when to signal the host:
One based on the ring buffer state and the other based on what the
VMBUS client driver wants to do. Consider the case when the client
wants to explicitly control when to signal the host. In this case,
if the client were to defer signaling, we will not be able to signal
the host subsequently when the client does want to signal since the
ring buffer state will prevent the signaling. Implement logic to
have only one signaling policy in force for a given channel.

commit ed8b0de5a33d2a2557dce7f9429dca8cb5bc5879 upstream.
"rm -rf" is bricking some peoples' laptops because of variables being
used to store non-reinitializable firmware driver data that's required
to POST the hardware.
These are 100% bugs, and they need to be fixed, but in the mean time it
shouldn't be easy to *accidentally* brick machines.
We have to have delete working, and picking which variables do and don't
work for deletion is quite intractable, so instead make everything
immutable by default (except for a whitelist), and make tools that
aren't quite so broad-spectrum unset the immutable flag.

Including the guid for entries will become more important in future
patches when we decide whether or not to allow deletion of variables
based on presence in this list.

commit 73500267c930baadadb0d02284909731baf151f7 upstream.
This adds ucs2_utf8size(), which tells us how big our ucs2 string is in
bytes, and ucs2_as_utf8, which translates from ucs2 to utf8..

[ Upstream commit 5f74f82ea34c0da80ea0b49192bb5ea06e063593 ]
Devices may have limits on the number of fragments in an skb they support.
Current codebase uses a constant as maximum for number of fragments one
skb can hold and use.
When enabling scatter/gather and running traffic with many small messages
the codebase uses the maximum number of fragments and may thereby violate
the max for certain devices.
The patch introduces a global variable as max number of fragments.

commit c74ba8b3480da6ddaea17df2263ec09b869ac496 upstream.
One of the easiest ways to protect the kernel from attack is to reduce
the internal attack surface exposed when a "write" flaw is available. By
making as much of the kernel read-only as possible, we reduce the
attack surface.
Many things are written to only during __init, and never changed
again. These cannot be made "const" since the compiler will do the wrong
thing (we do actually need to write to them). Instead, move these items
into a memory region that will be made read-only during mark_rodata_ro()
which happens after all kernel __init code has finished.
This introduces __ro_after_init as a way to mark such memory, and adds
some documentation about the existing __read_mostly marking.
This improves the security of the Linux kernel by marking formerly
read-write memory regions as read-only on a fully booted up system.
Based on work by PaX Team and Brad Spengler.

Remove the leds_off label and move the switch node disable
sequence into a separate function. Also take this opportunity
to move the flash-led structs from header file to driver file.

Since multiple devices may need to use the flash module,
each will need its own switch node to be able to
independently control the different leds. Add support for
this functionality.
