Rationale:
Reduces attack surface on kernel devs opening the links for MITM
as HTTPS traffic is much harder to manipulate.
Deterministic algorithm:
For each file:
If not .svg:
For each line:
If doesn't contain `\bxmlns\b`:
For each link, `\bhttp://[^# \t\r\n]*(?:\w|/)`:
If neither `\bgnu\.org/license`, nor `\bmozilla\.org/MPL\b`:
If both the HTTP and HTTPS versions
return 200 OK and serve the same content:
Replace HTTP with HTTPS.

The SH implementation never called stacktrace_ops.stack().
Presumably this was copied from the x86 implementation.
Hence remove the method, and all implementations (most of them are

This reverts commit 8b92f34877225c8eb85e3ab7f1177fc248ba26d0.
"data" became the log level in commit 539e786cc37ee5cb ("sh: add loglvl

continuation in print_trace_address().

This reverts commit d1f56f318d234fc5db230af2f3e0088f689ab3c0.
__delay() is an internal implementation detail on several architectures.
Drivers should not call __delay() directly, as it has non-standardized
semantics, or may not even exist.
Hence there is no need to export __delay() to modules.

When vxlan interface is deleted, all fdbs are deleted by vxlan_flush().
vxlan_flush() flushes fdbs but it doesn't delete fdb, which contains
all-zeros-mac because it is deleted by vxlan_uninit().
But vxlan_uninit() deletes only the fdb, which contains both all-zeros-mac
and default vni.
So, the fdb, which contains both all-zeros-mac and non-default vni
will not be deleted.

This reverts commit cc1c08edccaf5317d99a17a3231fe06381044e83.
Maxim Levitsky reports 'make xconfig' crashes since that commit
(https://lkml.org/lkml/2020/7/18/411)
Or, the following is simple test code that makes it crash:
menu "Menu"
config FOO
bool "foo"
default y
menuconfig BAR
bool "bar"
depends on FOO
endmenu
Select the Split View mode, and double-click "bar" in the right
window, then you will see Segmentation fault.
When 'last' is not set for symbolMode, the following code in
ConfigList::updateList() calls firstChild().
item = last ? last->nextSibling() : firstChild();
However, the pointer returned by ConfigList::firstChild() does not
seem to be compatible with (ConfigItem *), which seems another bug.
I'd rather want to reconsider whether hiding the goback icon is the
right thing to do.
In the following test code, the Split View shows "Menu2" and "Menu3"
in the right window. You can descend into "Menu3", but there is no way
to ascend back to "Menu2" from "Menu3".
menu "Menu1"
config FOO
bool "foo"
default y
menu "Menu2"
depends on FOO
menu "Menu3"
config BAZ
bool "baz"
endmenu
endmenu
endmenu
It is true that the goback button is currently not functional due to
yet another bug, but hiding the problem is not the right way to go.
Anyway, Segmentation fault is fatal. Revert the offending commit for
now, and we should find the right solution.

This reverts commit 5752ff07fd90d764d96e3c586cc95c09598abfdd.
It added dead code to ConfigList:ConfigList().
The constructor of ConfigList has the initializer, mode(singleMode).
if (mode == symbolMode)
setHeaderLabels(QStringList() << "Item" << "Name" << "N" << "M" << "Y" << "Value");
else
setHeaderLabels(QStringList() << "Option" << "Name" << "N" << "M" << "Y" << "Value");
... always takes the else part.
The change to ConfigList::updateSelection() is strange too.
When you click the split view icon for the first time, the titles in
both windows show "Option". After you click something in the right
window, the title suddenly changes to "Item".
ConfigList::updateSelection() is not the right place to do this,
at least. It was not a good idea, I think.

Regenerate qconf.moc when the moc command is changed.
This also allows 'make mrproper' to clean it up. Previously, it was
not cleaned up because 'clean-files += qconf.moc' was missing.
Now 'make mrproper' correctly cleans it up because files listed in
'targets' are cleaned.

rds_notify_queue_get() is potentially copying uninitialized kernel stack
memory to userspace since the compiler may leave a 4-byte hole at the end
of `cmsg`.
In 2016 we tried to fix this issue by doing `= { 0 };` on `cmsg`, which
unfortunately does not always initialize that 4-byte hole. Fix it by using
memset() instead.

When recording with cache-misses and arm_spe_x event, I found that it
will just fail without showing any error info if i put cache-misses
after 'arm_spe_x' event.
[root@localhost 0620]# perf record -e cache-misses \
-e arm_spe_0/ts_enable=1,pct_enable=1,pa_enable=1,load_filter=1,jitter=1,store_filter=1,min_latency=0/ sleep 1

-e cache-misses sleep 1
[root@localhost 0620]#
The current code can only work if the only event to be traced is an
'arm_spe_x', or if it is the last event to be specified. Otherwise the
last event type will be checked against all the arm_spe_pmus[i]->types,
none will match and an out of bound 'i' index will be used in
arm_spe_recording_init().
We don't support concurrent multiple arm_spe_x events currently, that
is checked in arm_spe_recording_options(), and it will show the relevant
info. So add the check and record of the first found 'arm_spe_pmu' to
fix this issue here.

'Commit 8566ac8b8e7c ("KVM: SVM: Implement pause loop exit logic in SVM")'
drops disable pause loop exit/pause filtering capability completely, I
guess it is a merge fault by Radim since disable vmexits capabilities and
pause loop exit for SVM patchsets are merged at the same time. This patch
reintroduces the disable pause loop exit/pause filtering capability support.

Accept the DRM_FORMAT_MOD_NVIDIA_16BX2_BLOCK()
family of modifiers to handle broken userspace
Xorg modesetting and Mesa drivers. Existing Mesa
drivers are still aware of only these older
format modifiers which do not differentiate
between different variations of the block linear
layout. When the format modifier support flag was
flipped in the nouveau kernel driver, the X.org
modesetting driver began attempting to use its
format modifier-enabled framebuffer path. Because
the set of format modifiers advertised by the
kernel prior to this change do not intersect with
the set of format modifiers advertised by Mesa,
allocating GBM buffers using format modifiers
fails and the modesetting driver falls back to
non-modifier allocation. However, it still later
queries the modifier of the GBM buffer when
creating its DRM-KMS framebuffer object, receives
the old-format modifier from Mesa, and attempts
to create a framebuffer with it. Since the kernel
is still not aware of these formats, this fails.
Userspace should not be attempting to query format
modifiers of GBM buffers allocated with a non-
format-modifier-aware allocation path, but to
avoid breaking existing userspace behavior, this
change accepts the old-style format modifiers when
creating framebuffers and applying them to planes
by translating them to the equivalent new-style
modifier. To accomplish this, some layout
parameters must be assumed to match properties of
the device targeted by the relevant ioctls. To
avoid perpetuating misuse of the old-style
modifiers, this change does not advertise support
for them. Doing so would imply compatibility
between devices with incompatible memory layouts.
Tested with Xorg 1.20 modesetting driver,
weston@c46c70dac84a4b3030cd05b380f9f410536690fc,

The function invokes bpf_prog_inc(), which increases the reference
count of a bpf_prog object "rq->xdp_prog" if the object isn't NULL.
The refcount leak issues take place in two error handling paths. When
either mlx5_wq_ll_create() or mlx5_wq_cyc_create() fails, the function
simply returns the error code and forgets to drop the reference count
increased earlier, causing a reference count leak of "rq->xdp_prog".
Fix this issue by jumping to the error handling path err_rq_wq_destroy
while either function fails.

The modified flow_context fields in FTE must be indicated in
modify_enable bitmask. Previously, the misc bit in modify_enable is
always set as source vport must be set for each rule. So, when parsing
vxlan/gre/geneve/qinq rules, this bit is not set because those are all
from the same misc fileds that source vport fields are located at, and
we don't need to set the indicator twice.
After adding per vport tables for mirroring, misc bit is not set, then
firmware syndrome happens. To fix it, set the bit wherever misc fileds
are changed. This also makes it unnecessary to check misc fields and set
the misc bit accordingly in metadata matching, so here remove it.
Besides, flow_source must be specified for uplink because firmware
will check it and some actions are only allowed for packets received
from uplink.

atmtcp_remove_persistent() invokes atm_dev_lookup(), which returns a
reference of atm_dev with increased refcount or NULL if fails.
The refcount leaks issues occur in two error handling paths. If
dev_data->persist is zero or PRIV(dev)->vcc isn't NULL, the function
returns 0 without decreasing the refcount kept by a local variable,
resulting in refcount leaks.
Fix the issue by adding atm_dev_put() before returning 0 both when
dev_data->persist is zero or PRIV(dev)->vcc isn't NULL.

Number of .dumpit functions try to ignore -EOPNOTSUPP errors.
Recent change missed that, and started reporting all errors
but -EMSGSIZE back from dumps. This leads to situation like
this:
$ devlink dev info
devlink answers: Operation not supported
Dump should not report an error just because the last device
to be queried could not provide an answer.
To fix this and avoid similar confusion make sure we clear
err properly, and not leave it set to an error if we don't
terminate the iteration.
