Move the check if the HW Tx ring is full to outside the send
loop. Currently it is checked for every single descriptor that we
send. Instead, tell the send loop to only process a maximum number of
packets equal to the number of available slots in the Tx ring. This
way, we can remove the check inside the send loop to and gain some
performance.

Eliminate a division in the napi_poll data path. This division is
executed even though it is only needed in the rare case when there are
not enough interrupt lines so they have to be shared between queue
pairs. Instead, just test for this case and only execute the division
if needed. The code has been lifted from the ice driver.

Improve the performance of the AF_XDP zero-copy Tx completion
path. When there are no XDP buffers being sent using XDP_TX or
XDP_REDIRECT, we do not have go through the SW ring to clean up any
entries since the AF_XDP path does not use these. In these cases, just
fast forward the next-to-use counter and skip going through the SW
ring. The limit on the maximum number of entries to complete is also
removed since the algorithm is now O(1). To simplify the code path, the
maximum number of entries to complete for the XDP path is therefore
also increased from 256 to 512 (the default number of Tx HW
descriptors). This should be fine since the completion in the XDP path
is faster than in the SKB path that has 256 as the maximum number.
This patch provides around 4% throughput improvement for the l2fwd
application in xdpsock on my machine.

After OS requests to down a link on a physical network port, the
traffic is no longer being processed but the physical link with
a link partner is still established.
Currently there is a feature (Link down on close) which allows
to physically bring the link down (after OS request).
With this patch new feature with similar capability is introduced:
TOTAL_PORT_SHUTDOWN
Allows to physically disable the link on the NIC's port.
If enabled, (after link down request from the OS)
no link, traffic or led activity is possible on that port.
If I40E_FLAG_TOTAL_PORT_SHUTDOWN is enabled, the
I40E_FLAG_LINK_DOWN_ON_CLOSE_ENABLED must be explicitly forced to
true and cannot be disabled at that time.
The functionalities are exclusive in terms of configuration, but
they also have similar behavior (allowing to disable physical link
of the port), with following differences:
- LINK_DOWN_ON_CLOSE_ENABLED is configurable at host OS run-time
and is supported by whole family of 7xx Intel Ethernet Controllers
- TOTAL_PORT_SHUTDOWN may be enabled only before OS loads (in BIOS)
only if motherboard's BIOS and NIC's FW has support of it
- when LINK_DOWN_ON_CLOSE_ENABLED is used, the link is being brought
down by sending phy_type=0 to NIC's FW
- when TOTAL_PORT_SHUTDOWN is used, phy_type is not altered, instead
the link is being brought down by clearing bit
(I40E_AQ_PHY_ENABLE_LINK) in abilities field of
i40e_aq_set_phy_config structure
Introduced changes:
- new private flag I40E_FLAG_TOTAL_PORT_SHUTDOWN for handling the
feature
- probe of NVM if the feature was enabled at driver's port
initialization
- special handling on link-down procedure to let FW physically
shutdown the port if the feature was enabled

====================
net: ethernet: use generic power management
Linux Kernel Mentee: Remove Legacy Power Management.
The purpose of this patch series is to remove legacy power management callbacks
from net ethernet drivers.
The callbacks performing suspend() and resume() operations are still calling
pci_save_state(), pci_set_power_state(), etc. and handling the power management
themselves, which is not recommended.
The conversion requires the removal of the those function calls and change the
callback definition accordingly and make use of dev_pm_ops structure.
All patches are compile-tested only.

With legacy PM, drivers themselves were responsible for managing the
device's power states and takes care of register states.
After upgrading to the generic structure, PCI core will take care of
required tasks and drivers should do only device-specific operations.
Thus, there is no need to call the PCI helper functions like
pci_enable_device, which is not recommended. Hence, removed.

Drivers should not use legacy power management as they have to manage power
states and related operations, for the device, themselves. This driver was
handling them with the help of PCI helper functions.
With generic PM, all essentials will be handled by the PCI core. Driver
needs to do only device-specific operations.
The driver defined empty-body .suspend() and .resume() callbacks earlier.
They can now be define NULL and bind with "struct dev_pm_ops" variable.

With legacy PM, drivers themselves were responsible for managing the
device's power states and takes care of register states. And they use PCI
helper functions to do it.
After upgrading to the generic structure, PCI core will take care of
required tasks and drivers should do only device-specific operations.
In this driver:
typhoon_resume() calls typhoon_wakeup() which then calls PCI helper
functions pci_set_power_state() and pci_restore_state(). The only other
function, using typhoon_wakeup() is typhoon_open().
Thus remove the pci_*() calls from tyhpoon_wakeup() and place them in
typhoon_open(), maintaining the order, to retain the normal behavior of
the function
Now, typhoon_suspend() calls typhoon_sleep() which then calls PCI helper
functions pci_enable_wake(), pci_disable_device() and
pci_set_power_state(). Other functions:
- typhoon_open()
- typhoon_close()
- typhoon_init_one()
are also invoking typhoon_sleep(). Thus, in this case, cannot simply
move PCI helper functions call.
Hence, define a new function typhoon_sleep_early() which will do all the
operations, which typhoon_sleep() was doing before calling PCI helper
functions. Now typhoon_sleep() will call typhoon_sleep_early() to do
those tasks, hence, the behavior for _open(), _close and _init_one() remain
unchanged. And typhon_suspend() only requires typhoon_sleep_early().

CPU Measurement sampling facility on s390 does not support
perf tool collection of callchain data using --call-graph
option. The sampling facility collects samples in a ring
buffer which includes only the instruction address the
samples were taken. When the ring buffer hits a watermark,
a measurement alert interrupt is triggered and handled
by the performance measurement unit (PMU) device driver.
It collects the samples and feeds each sample to the
perf ring buffer in the common code via functions
perf_prepare_sample()/perf_output_sample(). When function
perf_prepare_sample() is called to collect sample data's
callchain, user register values or stack area, invalid
data is picked, because the context of the collected
information does not match the context when the sample
was taken.
There is currently no way to provide the callchain and other
information, because the hardware sampler does not collect this
information.
Therefore prohibit sampling when the user requests a callchain graph
from the hardware sampler. Return -EOPNOTSUPP to the user in this
case.
If call chains are really wanted, users need to specify software
event cpu-clock to get the callchain information from a
software event.

====================
This set introduces a new helper bpf_get_task_stack(). The primary use case
is to dump all /proc/*/stack to seq_file via bpf_iter__task.
A few different approaches have been explored and compared:
1. A simple wrapper around stack_trace_save_tsk(), as v1 [1].
This approach introduces new syntax, which is different to existing
helper bpf_get_stack(). Therefore, this is not ideal.
2. Extend get_perf_callchain() to support "task" as argument.
This approach reuses most of bpf_get_stack(). However, extending
get_perf_callchain() requires non-trivial changes to architecture
specific code. Which is error prone.
3. Current (v2) approach, leverages most of existing bpf_get_stack(), and
uses stack_trace_save_tsk() to handle architecture specific logic.

Introduce helper bpf_get_task_stack(), which dumps stack trace of given
task. This is different to bpf_get_stack(), which gets stack track of
current task. One potential use case of bpf_get_task_stack() is to call
it from bpf_iter__task and dump all /proc/<pid>/stack to a seq_file.
bpf_get_task_stack() uses stack_trace_save_tsk() instead of
get_perf_callchain() for kernel stack. The benefit of this choice is that
stack_trace_save_tsk() doesn't require changes in arch/. The downside of
using stack_trace_save_tsk() is that stack_trace_save_tsk() dumps the
stack trace to unsigned long array. For 32-bit systems, we need to
translate it to u64 array.

bpf_free_used_maps() is called after bpf prog is no longer executing:
bpf_prog_put->call_rcu->bpf_prog_free->bpf_free_used_maps.
Hence there is no need to call synchronize_rcu() to protect map elements.

The Qt5 conversion broke support for debug info links.
Restore the behaviour added by changeset
ab45d190fd4a ("kconfig: create links in info window").
The original approach was to pass a pointer for a data struct
via an <a href>. That doesn't sound a good idea, as, if something
gets wrong, the app could crash. So, instead, pass the name of
the symbol, and validate such symbol at the hyperlink handling
logic.

When the search dialog box finds symbols/menus that match
the search criteria, it presents all results at the window.
Clicking on a search result should make qconf to navigate
to the selected item. This works on singleMode and on
fullMode, but on splitMode, the navigation is broken.
This was partially caused by an incomplete Qt5 conversion
and by the followup patches that restored the original
behavior.
When qconf is on split mode, it has to update both the
config and the menu views. Right now, such logic is broken,
as it is not seeking using the right structures.
On qconf, the screen is split into 3 parts:
+------------+-------+
| | |
| Config | Menu |
| | |
+------------+-------+
| |
| ConfigInfo |
| |
+--------------------+
On singleMode and on fullMode, the menuView is hidden, and search
updates only the configList (which controls the ConfigView).
On SplitMode, the search logic should detect if the variable is a
leaf or not. If it is a leaf, it should be presented at the menuView,
and both configList and menuList should be updated. Otherwise, just
the configList should be updated.

The usage of c-like include is deprecated on modern Qt
versions. Use the c++ style includes.
While here, remove uneeded and redundant ones, sorting
them on alphabetic order.

Add new functions ip_vs_conn_del() and ip_vs_conn_del_put()
to release many IPVS connections in process context.
They are suitable for connections found in table
when we do not want to overload the timers.
Currently, the change is useful for the dropentry delayed
work but it will be used also in following patch
when flushing connections to failed destinations.

There are several copies of get_eflags() and set_eflags() and they all are
buggy. Consolidate them and fix them. The fixes are:
Add memory clobbers. These are probably unnecessary but they make sure
that the compiler doesn't move something past one of these calls when it
shouldn't.
Respect the redzone on x86_64. There has no failure been observed related
to this, but it's definitely a bug.

Clear the weird flags before logging to improve strace output --
logging results while, say, TF is set does no one any favors.

The SYSENTER frame setup was nonsense. It worked by accident because the
normal code into which the Xen asm jumped (entry_SYSENTER_32/compat) threw
away SP without touching the stack. entry_SYSENTER_compat was recently
modified such that it relied on having a valid stack pointer, so now the
Xen asm needs to invoke it with a valid stack.
Fix it up like SYSCALL: use the Xen-provided frame and skip the bare
metal prologue.
