Don't call the ->break_handler() from the powerpc kprobes code,
because it was only used by jprobes which got removed.
This also removes skip_singlestep() and embeds it in the
caller, kprobe_ftrace_handler(), which simplifies regs->nip
operation around there.

Don't check the ->break_handler() from the core kprobes code,

( In followup patches we'll remove the remaining calls in low level
arch handlers as well and remove the callback altogether. )

Remove arch dependent setjump/longjump functions
and unused fields in kprobe_ctlblk for jprobes
from arch/ia64.
Note that since ia64 jprobes code is a bit different
from other architectures, this keeps __IA64_BREAK_JPROBE
for checking the ->break_handler(). It will be removed
with the break_handler() calls afterwards.

The HID descriptor for the 2nd-gen Intuos Pro large (PTH-860) contains
a typo which defines an incorrect logical maximum Y value. This causes
a small portion of the bottom of the tablet to become unusable (both
because the area is below the "bottom" of the tablet and because
'wacom_wac_event' ignores out-of-range values). It also results in a
skewed aspect ratio.
To fix this, we add a quirk to 'wacom_usage_mapping' which overwrites
the data with the correct value.

Current ISH driver only registers suspend/resume PM callbacks which don't
support hibernation (suspend to disk). Basically after hiberation, the ISH
can't resume properly and user may not see sensor events (for example: screen
rotation may not work).
User will not see a crash or panic or anything except the following message
in log:
hid-sensor-hub 001F:8086:22D8.0001: timeout waiting for response from ISHTP device
So this patch adds support for S4/hiberbation to ISH by using the
SIMPLE_DEV_PM_OPS() MACRO instead of struct dev_pm_ops directly. The suspend
and resume functions will now be used for both suspend to RAM and hibernation.
If power management is disabled, SIMPLE_DEV_PM_OPS will do nothing, the suspend
and resume related functions won't be used, so mark them as __maybe_unused to
clarify that this is the intended behavior, and remove #ifdefs for power
management.

When creating the low-level hidraw device, the reference to steam_device
was stored using hid_set_drvdata(). But this value is not guaranteed to
be kept when set before calling probe. If this pointer is reset, it
crashes when opening the emulated hidraw device.
It looks like hid_set_drvdata() is for users "avobe" this hid_device,
while hid_device.driver_data it for users "below" this one.
In this case, we are creating a virtual hidraw device, so we must use
hid_device.driver_data.

The rewrite of the cmdline fetching missed the fact that we used to also
return the final terminating NUL character of the last argument. I
hadn't noticed, and none of the tools I tested cared, but something
obviously must care, because Michal Kubecek noticed the change in
behavior.
Tweak the "find the end" logic to actually include the NUL character,
and once past the eend of argv, always start the strnlen() at the
expected (original) argument end.
This whole "allow people to rewrite their arguments in place" is a nasty
hack and requires that odd slop handling at the end of the argv array,
but it's our traditional model, so we continue to support it.

The ipcm(6)_cookie field gso_size is set only in the udp path. The ip
layer copies this to cork only if sk_type is SOCK_DGRAM. This check
proved too permissive. Ping and l2tp sockets have the same type.
Limit to sockets of type SOCK_DGRAM and protocol IPPROTO_UDP to
exclude ping sockets.

The Stratix10 platform has an additional reset line, OCP(Open Core Protocol),
that also needs to get deasserted for the stmmac ethernet controller to work.
Thus we need to update the Kconfig to include ARCH_STRATIX10 in order to build
dwmac-socfpga.
Also, remove the redundant check for the reset controller pointer. The
reset driver already checks for the pointer and returns 0 if the pointer
is NULL.

After commit 88078d98d1bb ("net: pskb_trim_rcsum() and CHECKSUM_COMPLETE
are friends"), sungem owners reported the infamous "eth0: hw csum failure"
message.
CHECKSUM_COMPLETE has in fact never worked for this driver, but this
was masked by the fact that upper stacks had to strip the FCS, and
therefore skb->ip_summed was set back to CHECKSUM_NONE before
my recent change.
Driver configures a number of bytes to skip when the chip computes
the checksum, and for some reason only half of the Ethernet header
was skipped.
Then a second problem is that we should strip the FCS by default,
unless the driver is updated to eventually support NETIF_F_RXFCS in
the future.
Finally, a driver should check if NETIF_F_RXCSUM feature is enabled
or not, so that the admin can turn off rx checksum if wanted.
Many thanks to Andreas Schwab and Mathieu Malaterre for their
help in debugging this issue.

a recursive lock warning [1] can be observed with the following script,
# $TC actions add action ife encode allow prio pass index 42
IFE type 0xED3E
# $TC actions replace action ife encode allow tcindex pass index 42
in case the kernel was unable to run the last command (e.g. because of
the impossibility to load 'act_meta_skbtcindex'). For a similar reason,
the kernel can leak idr in the error path of tcf_ife_init(), because
tcf_idr_release() is not called after successful idr reservation:
# $TC actions add action ife encode allow tcindex index 47
IFE type 0xED3E
RTNETLINK answers: No such file or directory
We have an error talking to the kernel
# $TC actions add action ife encode allow tcindex index 47
IFE type 0xED3E
RTNETLINK answers: No space left on device
We have an error talking to the kernel
# $TC actions add action ife encode use mark 7 type 0xfefe pass index 47
IFE type 0xFEFE
RTNETLINK answers: No space left on device
We have an error talking to the kernel
Since tcfa_lock is already taken when the action is being edited, a call
to tcf_idr_release() wrongly makes tcf_idr_cleanup() take the same lock
again. On the other hand, tcf_idr_release() needs to be called in the
error path of tcf_ife_init(), to undo the last tcf_idr_create() invocation.
Fix both problems in tcf_ife_init().
Since the cleanup() routine can now be called when ife->params is NULL,
also add a NULL pointer check to avoid calling kfree_rcu(NULL, rcu).

This patch reverts commit 3243ff2a05ec ("net: ethernet: davinci_emac:
Deduplicate bus_find_device() by name matching") and adds a comment
which should stop anyone from reintroducing the same "fix" in the future.
We can't use bus_find_device_by_name() here because the device name is
not guaranteed to be 'davinci_mdio'. On some systems it can be
'davinci_mdio.0' so we need to use strncmp() against the first part of
the string to correctly match it.

Similar to 69678bcd4d2d ("udp: fix SO_BINDTODEVICE"), TCP socket lookups
need to fail if dev_match is not true. Currently, a packet to a given port
can match a socket bound to device when it should not. In the VRF case,
this causes the lookup to hit a VRF socket and not a global socket
resulting in a response trying to go through the VRF when it should not.

Similar to the fixes on team and bonding, this restores the ability
to set an ipvlan device's mtu to anything higher than 1500.

The array bpq_eth_addr is only used to get the size of an
address, whereas the bcast_addr is used to set the broadcast
address. This leads to a warning when using clang:
drivers/net/hamradio/bpqether.c:94:13: warning: variable 'bpq_eth_addr' is not
needed and will not be emitted [-Wunneeded-internal-declaration]
static char bpq_eth_addr[6];
^
Remove both variables and use the common eth_broadcast_addr
to set the broadcast address.

lockdep spotted that we are using rfs_h.lock in enic_get_rxnfc() without
initializing. rfs_h.lock is initialized in enic_open(). But ethtool_ops
can be called when interface is down.
Move enic_rfs_flw_tbl_init to enic_probe.
INFO: trying to register non-static key.
the code is fine but needs lockdep annotation.
turning off the locking correctness validator.
