In case an under-voltage happens before probing the driver wont
write the critical warning into the kernel log. So don't init
of last_throttled during probe and fix this issue.

When using DT configurations, the id pointer might turn out to
be NULL. Then the driver encounters NULL pointer access:
Unable to handle kernel read from unreadable memory at vaddr 00000018
[...]
PC is at ina2xx_probe+0x114/0x200
LR is at ina2xx_probe+0x10c/0x200
[...]
Kernel panic - not syncing: Attempted to kill init! exitcode=0x0000000b
The reason is that i2c core returns the id pointer by matching
id_table with client->name, while the client->name is actually
using the name from the first string in the DT compatible list,
not the best one. So i2c core would fail to match the id_table
if the best matched compatible string isn't the first one, and
then would return a NULL id pointer.
This probably should be fixed in i2c core. But it doesn't hurt
to make the driver robust. So this patch fixes it by using the
"chip" that's added to unify both DT and non-DT configurations.
Additionally, since id pointer could be null, so as id->name:
ina2xx 10-0047: power monitor (null) (Rshunt = 1000 uOhm)
ina2xx 10-0048: power monitor (null) (Rshunt = 10000 uOhm)
So this patch also fixes NULL name pointer, using client->name
to play safe and to align with hwmon->name.

Certain flows need to access the rdma-info structure, for example dcbx
update flows. In some cases there can be a race between the allocation or
deallocation of the structure which was done in roce start / roce stop and
an asynchrounous dcbx event that tries to access the structure.
For this reason, we move the allocation of the rdma_info structure to be
similar to the iscsi/fcoe info structures which are allocated during device
setup.
We add a new field of "active" to the struct to define whether roce has
already been started or not, and this is checked instead of whether the
pointer to the info structure.

====================
pull-request: can 2018-11-09
this is a pull request of 20 patches for net/master.
First we have a patch by Oliver Hartkopp which changes the raw socket's
raw_sendmsg() to return an error value if the user tries to send a CANFD
frame to a CAN-2.0 device.
The next two patches are by Jimmy Assarsson and fix potential problems
in the kvaser_usb driver.
YueHaibing's patches for the ucan driver fix a compile time warning and
remove a duplicate include.
Eugeniu Rosca patch adds more binding documentation to the rcar_can
driver bindings. The next two patches are by Fabrizio Castro for the
rcar_can driver and fixes a problem in the driver's probe function and
document the r8a774a1 binding.
Lukas Wunner's patch fixes a recpetion problem in hi311x driver by
switching from edge to level triggered interruts.
The next three patches all target the flexcan driver. Pankaj Bansal's
patch unconditionally unlocks the last mailbox used for RX. Alexander
Stein provides a better workaround for a hardware limitation when
sending RTR frames, by using the last mailbox for TX, resulting in fewer
lost frames. The patch by me simplyfies the driver, by making a runtime
value a compile time constant.
The following 4 patches are by me and provide the groundwork for the
next patches by Oleksij Rempel. To avoid code duplication common code in
the common CAN driver infrastructure is factured out and error handling
is cleaned up.
The next 4 patches are by Oleksij Rempel and fix the problem in the
flexcan driver that other processes see TX frames arrive out of order
with ragards to a RX'ed frame (which are send by a different system on
the CAN bus as the result of our TX frame).

After the simplification of the fast fsync patch done recently by commit
b5e6c3e170b7 ("btrfs: always wait on ordered extents at fsync time") and
commit e7175a692765 ("btrfs: remove the wait ordered logic in the
log_one_extent path"), we got a very short time window where we can get
extents logged without writeback completing first or extents logged
without logging the respective data checksums. Both issues can only happen
when doing a non-full (fast) fsync.
As soon as we enter btrfs_sync_file() we trigger writeback, then lock the
inode and then wait for the writeback to complete before starting to log
the inode. However before we acquire the inode's lock and after we started
writeback, it's possible that more writes happened and dirtied more pages.
If that happened and those pages get writeback triggered while we are
logging the inode (for example, the VM subsystem triggering it due to
memory pressure, or another concurrent fsync), we end up seeing the
respective extent maps in the inode's list of modified extents and will
log matching file extent items without waiting for the respective
ordered extents to complete, meaning that either of the following will
happen:
1) We log an extent after its writeback finishes but before its checksums
are added to the csum tree, leading to -EIO errors when attempting to
read the extent after a log replay.
2) We log an extent before its writeback finishes.
Therefore after the log replay we will have a file extent item pointing
to an unwritten extent (and without the respective data checksums as
well).
This could not happen before the fast fsync patch simplification, because
for any extent we found in the list of modified extents, we would wait for
its respective ordered extent to finish writeback or collect its checksums
for logging if it did not complete yet.
Fix this by triggering writeback again after acquiring the inode's lock
and before waiting for ordered extents to complete.

Fixes: b5e6c3e170b7 ("btrfs: always wait on ordered extents at fsync time")

nft_compat ops do not have static storage duration, unlike all other
expressions.
When nf_tables_expr_destroy() returns, expr->ops might have been
free'd already, so we need to store next address before calling
expression destructor.
For same reason, we can't deref match pointer after nft_xt_put().
This can be easily reproduced by adding msleep() before
nft_match_destroy() returns.

The voltage range (min, max) provided in the device tree is from
the data manual and is pretty big, catering to a wide range of devices.
On a i2c read/write failure the regulator_set_voltage_triplet function
falls back to set voltage between min and max. The min value from Device
Tree can be lesser than the optimal value and in that case that can lead
to a hang or crash. Hence set the u_volt_min dynamically to the optimal
voltage value.

When a metadata read is served the endio routine btree_readpage_end_io_hook
is called which eventually runs the tree-checker. If tree-checker fails
to validate the read eb then it sets EXTENT_BUFFER_CORRUPT flag. This
leads to btree_read_extent_buffer_pages wrongly assuming that all
available copies of this extent buffer are wrong and failing prematurely.
Fix this modify btree_read_extent_buffer_pages to read all copies of
the data.
This failure was exhibitted in xfstests btrfs/124 which would
spuriously fail its balance operations. The reason was that when balance
was run following re-introduction of the missing raid1 disk
__btrfs_map_block would map the read request to stripe 0, which
corresponded to devid 2 (the disk which is being removed in the test):
item 2 key (FIRST_CHUNK_TREE CHUNK_ITEM 3553624064) itemoff 15975 itemsize 112
length 1073741824 owner 2 stripe_len 65536 type DATA|RAID1
io_align 65536 io_width 65536 sector_size 4096
num_stripes 2 sub_stripes 1
stripe 0 devid 2 offset 2156920832
dev_uuid 8466c350-ed0c-4c3b-b17d-6379b445d5c8
stripe 1 devid 1 offset 3553624064
dev_uuid 1265d8db-5596-477e-af03-df08eb38d2ca
This caused read requests for a checksum item that to be routed to the
stale disk which triggered the aforementioned logic involving
EXTENT_BUFFER_CORRUPT flag. This then triggered cascading failures of
the balance operation.

Commit 07d02a67b7fa causes a use-after free in the RPCSEC_GSS credential
destroy code, because the call to get_rpccred() in gss_destroying_context()
will now always fail to increment the refcount.
While we could just replace the get_rpccred() with a refcount_set(), that
would have the unfortunate consequence of resurrecting a credential in
the credential cache for which we are in the process of destroying the
RPCSEC_GSS context. Rather than do this, we choose to make a copy that
is never added to the cache and use that to destroy the context.

If we exit the NFSv4 state manager due to a umount, then we can end up
leaving the NFS4CLNT_MANAGER_RUNNING flag set. If another mount causes
the nfs4_client to be rereferenced before it is destroyed, then we end

The cros_ec_keyb_bs array lists buttons and switches together, expecting
that its users will match the appropriate type and bit fields. But
cros_ec_keyb_register_bs() only checks the 'bit' field, which causes
misreported input capabilities in some cases. For example, tablets
(e.g., Scarlet -- a.k.a. Acer Chromebook Tab 10) were reporting a SW_LID
capability, because EC_MKBP_POWER_BUTTON and EC_MKBP_LID_OPEN happen to
share the same bit.
(This has comedic effect on a tablet, in which a power-management daemon
then thinks this "lid" is closed, and so puts the system to sleep as
soon as it boots!)
To fix this, check both the 'ev_type' and 'bit' fields before reporting
the capability.
Tested with a lid (Kevin / Samsung Chromebook Plus) and without a lid
(Scarlet / Acer Chromebook Tab 10).
This error got introduced when porting the feature from the downstream
Chromium OS kernel to be upstreamed.

"of_get_named_gpio()" returns a negative error value if it fails
and drivers should check for this. This missing check was now
added to the matrix_keypad driver.
In my case "of_get_named_gpio()" returned -EPROBE_DEFER because
the referenced GPIOs belong to an I/O expander, which was not yet
probed at the point in time when the matrix_keypad driver was
loading. Because the driver did not check for errors from the
"of_get_named_gpio()" routine, it was assuming that "-EPROBE_DEFER"
is actually a GPIO number and continued as usual, which led to further
errors like this later on:
WARNING: CPU: 3 PID: 167 at drivers/gpio/gpiolib.c:114
gpio_to_desc+0xc8/0xd0
invalid GPIO -517
Note that the "GPIO number" -517 in the error message above is
actually "-EPROBE_DEFER".
As part of the patch a misleading error message "no platform data defined"
was also removed. This does not lead to information loss because the other
error paths in matrix_keypad_parse_dt() already print an error.

them have been fixed and some of them haven't. I find that many of them
are because of memory allocations are top-down, while the old behavior
is bottom-up. This patch let early memblock_alloc*() allocate memories
bottom-up to avoid some potential problems.
