Currently because of the left associativity of the operators, pattern
IRQF_ONESHOT | flags does not match with the pattern when we have more
than one flag after the disjunction. This eventually results in giving
false positives by the script. This patch eliminates these FPs by
improving the rule.

The sync_cmos_clock function in kernel/time/ntp.c first tries to update
the internal clock of the cpu by calling the "update_persistent_clock64"
architecture specific function. If this returns -ENODEV, it then tries
to update an external RTC using "rtc_set_ntp_time".
On the mips architecture, the weak implementation of the underlying
function would return 0 if it wasn't overridden. This meant that the
sync_cmos_clock function would never try to update an external RTC
(if both CONFIG_GENERIC_CMOS_UPDATE and CONFIG_RTC_SYSTOHC are
configured)
Returning -ENODEV instead, means that an external RTC will be tried.

The .match_method field is a u8, so we shouldn't be casting to a u16,

Just assign the value directly. This avoids issues on Big Endian

Instead of having individual PHY drivers set the SUPPORTED_Pause and
SUPPORTED_Asym_Pause flags, phylib itself should set those flags,
unless there is a hardware erratum or other special case. During
autonegotiation, the PHYs will determine whether to enable pause
frame support.
Pause frames are a feature that is supported by the MAC. It is the MAC
that generates the frames and that processes them. The PHY can only be
configured to allow them to pass through.
This commit also effectively reverts the recently applied c7a61319
("net: phy: dp83848: Support ethernet pause frames").
So the new process is:
1) Unless the PHY driver overrides it, phylib sets the SUPPORTED_Pause
and SUPPORTED_AsymPause bits in phydev->supported. This indicates that
the PHY supports pause frames.
2) The MAC driver checks phydev->supported before it calls phy_start().
If (SUPPORTED_Pause | SUPPORTED_AsymPause) is set, then the MAC driver
sets those bits in phydev->advertising, if it wants to enable pause
frame support.
3) When the link state changes, the MAC driver checks phydev->pause and
phydev->asym_pause, If the bits are set, then it enables the corresponding
features in the MAC. The algorithm is:
if (phydev->pause)
The MAC should be programmed to receive and honor
pause frames it receives, i.e. enable receive flow control.
if (phydev->pause != phydev->asym_pause)
The MAC should be programmed to transmit pause
frames when needed, i.e. enable transmit flow control.

first taking the private lock and (in case that the tx queue had been

====================
net: bridge: fast ageing on topology change
802.1D [1] specifies that the bridges in a network must use a short
value to age out dynamic entries in the Filtering Database for a period,
once a topology change has been communicated by the root bridge.
This patchset fixes this for the in-kernel STP implementation.
Once the topology change flag is set in a net_bridge instance, the
ageing time value is shorten to twice the forward delay used by the
topology.
When the topology change flag is cleared, the ageing time configured for
the bridge is restored.
To accomplish that, a new bridge_ageing_time member is added to the
net_bridge structure, to store the user configured bridge ageing time.
Two helpers are added to offload the ageing time and set the topology
change flag in the net_bridge instance. Then the required logic is added
in the topology change helper if in-kernel STP is used.
This has been tested on the following topology:
+--------------+
| root bridge |
| 1 2 3 4 |
+--+--+--+--+--+
| | | | +--------+
| | | +------| laptop |
| | | +--------+
+--+--+--+-----+
| 1 2 3 |
| slave bridge |
+--------------+
When unplugging/replugging the laptop, the slave bridge (under test)
gets the topology change flag sent by the root bridge, and fast ageing
is triggered on the bridges. Once the topology change timer of the root
bridge expires, the topology change flag is cleared and the configured
ageing time is restored on the bridges.
A similar test has been done between two bridges under test.
When changing the forward delay of the root bridge with:
# echo 3000 > /sys/class/net/br0/bridge/forward_delay
the ageing time correctly changes on both bridges from 300s to 60s while
the TOPOLOGY_CHANGE flag is present.

Currently data journalling is incompatible with encryption: enabling both
at the same time has never been supported by design, and would result in
unpredictable behavior. However, users are not precluded from turning on
both features simultaneously. This change programmatically replaces data
journaling for encrypted regular files with ordered data journaling mode.
Background:
Journaling encrypted data has not been supported because it operates on
buffer heads of the page in the page cache. Namely, when the commit
happens, which could be up to five seconds after caching, the commit
thread uses the buffer heads attached to the page to copy the contents of
the page to the journal. With encryption, it would have been required to
keep the bounce buffer with ciphertext for up to the aforementioned five
seconds, since the page cache can only hold plaintext and could not be
used for journaling. Alternatively, it would be required to setup the
journal to initiate a callback at the commit time to perform deferred
encryption - in this case, not only would the data have to be written
twice, but it would also have to be encrypted twice. This level of
complexity was not justified for a mode that in practice is very rarely
used because of the overhead from the data journalling.
Solution:
If data=journaled has been set as a mount option for a filesystem, or if
journaling is enabled on a regular file, do not perform journaling if the
file is also encrypted, instead fall back to the data=ordered mode for the
file.
Rationale:
The intent is to allow seamless and proper filesystem operation when
journaling and encryption have both been enabled, and have these two
conflicting features gracefully resolved by the filesystem.

We thought that no userspace is using them, but oops libdrm is using
them to figure out whether a driver supports modesetting. Check out
drmCheckModesettingSupported but maybe don't because it's horrible and
totally runs counter to where we want to go with libdrm device
handling. The function looks in the device hierarchy for whether
controlD* exist using the following format string:
/sys/bus/pci/devices/%04x:%02x:%02x.%d/drm/controlD%d
The "/drm" subdirectory is the glue directory from the sysfs class
stuff, and the only way to get at it seems to through
kdev->kobj.parent (when kdev is represents e.g. the card0 chardev
instance in sysfs). Git grep says we're not the only ones touching
that, so I hope it's ok we dig into such internals - I couldn't find a
proper interface for getting at the glue directory.
Quick git grep shows that at least -amdgpu, -ati are using this.
-modesetting do not, and on -intel it's only about the 4th fallback
path for device lookup, which is why this didn't blow up earlier.
Oh well, we need to keep it working, and the simplest way is to add a
symlink at the right place in sysfs from controlD* to card*.
v2:
- Fix error path handling by adding if (!minor) return checks (David)
- Fix the controlD* numbers to match what's been there (David)
- Add a comment what exactly userspace minimally needs.
- Correct the analysis for -intel (Chris).

If we had a short copy into an uptodate page, there's no reason

a) the page is uptodate - ->write_begin() would either fail (in which
case we don't reach ->write_end()), or unstuff the inode, or find the
page already uptodate, or do a successful call of stuffed_readpage(),
which would've made it uptodate
b) zeroing the tail in pagecache is wrong. kill -9 at the right time
while writing unmodified file contents to the same file should _not_
leave us in a situation when read() from the file will be reporting
it full of zeroes. Especially since that effect will be transient -
at some later point the page will be evicted and then we'll be back
