The kernel starts out its "jiffies" timer as 5 minutes below zero, as
shown in include/linux/jiffies.h:
/*
* Have the 32 bit jiffies value wrap 5 minutes after boot
* so jiffies wrap bugs show up earlier.
*/
#define INITIAL_JIFFIES ((unsigned long)(unsigned int) (-300*HZ))
The loop in ovs_flow_stats_get() starts out with 'used' set to 0, then
takes any "later" time. This means that for the first five minutes after
boot, flows will always be reported as never used, since 0 is greater than
any time already seen.

In event format strings, the array size is reported in two locations.
One in array subscript and then via the "size:" attribute. The values
reported there have a mismatch.
For e.g., in sched:sched_switch the prev_comm and next_comm character
arrays have subscript values as [32] where as the actual field size is
16.
name: sched_switch
ID: 301
format:
field:unsigned short common_type; offset:0; size:2; signed:0;
field:unsigned char common_flags; offset:2; size:1; signed:0;
field:unsigned char common_preempt_count; offset:3; size:1;signed:0;
field:int common_pid; offset:4; size:4; signed:1;
field:char prev_comm[32]; offset:8; size:16; signed:1;
field:pid_t prev_pid; offset:24; size:4; signed:1;
field:int prev_prio; offset:28; size:4; signed:1;
field:long prev_state; offset:32; size:8; signed:1;
field:char next_comm[32]; offset:40; size:16; signed:1;
field:pid_t next_pid; offset:56; size:4; signed:1;
field:int next_prio; offset:60; size:4; signed:1;
After bisection, the following commit was blamed:
92edca0 tracing: Use direct field, type and system names
This commit removes the duplication of strings for field->name and
field->type assuming that all the strings passed in
__trace_define_field() are immutable. This is not true for arrays, where
the type string is created in event_storage variable and field->type for
all array fields points to event_storage.
Use __stringify() to create a string constant for the type string.
Also, get rid of event_storage and event_storage_mutex that are not
needed anymore.
also, an added benefit is that this reduces the overhead of events a bit more:

We need to ensure that we do not send events to user space with the
identity address if we have not yet notified user space of the IRK. The
code was previously trying to handle this for the mgmt_pair_device
response (which worked well enough) but this is not the only connection
related event that might be sent to user space before pairing is
successful: another important event is Device Disconnected.
The issue can actually be solved more simply than the solution
previously used for mgmt_pair_device. Since we do have the identity
address tracked as part of the remote IRK struct we can just copy it
over from there to the hci_conn struct once we've for real sent the mgmt
event for the new IRK.

The watchdog thread waits on completion that is set from a timer. As
the completion is count based this could mean that on a busy system
the watchdog is handled multiple times with a very short interval.
This is not the intended behaviour. After handling the watchdog it
should wait for the next timer expiry. This is accomplished by
reinitializing the completion.

linux/compat.h does not include linux/unistd.h but the compat.h header
file contains various conditional
#ifdef __ARCH_WANT_COMPAT_...
asmlinkage long compat...()
#endif
compat system call function declarations.
If linux/unistd.h isn't included it depends on previous includes if those
__ARCH_WANT_COMPAT_... defines are defined or not. So add an additional
linux/unistd.h include.
Should fix this compile error on tile:

For non-mipsr2 processors, the local_irq_disable contains an mfc0-mtc0
pair with instructions inbetween. With preemption enabled, this sequence
may get preempted and effect a stale value of CP0_STATUS when executing
the mtc0 instruction. This commit avoids this scenario by incrementing
the preempt count before the mfc0 and decrementing it after the mtc9.
[ralf@linux-mips.org: This patch is sorting out the part that were missed
by e97c5b6098 [MIPS: Make irqflags.h functions preempt-safe for non-mipsr2
cpus.] I also re-enabled the inclusion of <asm/asm-offsets.h> at the top

There are only two users of get_nohz_timer_target(): timer and hrtimer. Both
call it under same circumstances, i.e.
#ifdef CONFIG_NO_HZ_COMMON
if (!pinned && get_sysctl_timer_migration() && idle_cpu(this_cpu))
return get_nohz_timer_target();
#endif
So, it makes more sense to get all this as part of get_nohz_timer_target()
instead of duplicating code at two places. For this another parameter is
required to be passed to this routine, pinned.

This patch moves the call to enable Tx queues after the link is established.
Previously there was a chance for aggressive start_ndo_xmit() callers to
sneak packets between enabling the Tx queues and the link coming up.
In addition it replaces netif_tx_start_all_queues() with
netif_tx_wake_all_queues() to allow for flushing of the qdisc.

This patch fixes flow control autonegotiation for KR/KX/K4 interfaces.
When setting up MAC link, the cached autoc value and current autoc value
were being incorrectly used to determine whether link reset is required.
This resulted in the driver ignoring and discarding flow control
negotiation changes that occur since the caching happened, as well as
when the mac was being setup.
This patch also splits the assignments for the 3 autoc variables into
their own block, and adds a comment explaining what each one means, in
order to help keep logic more straightforward while reading the code.

This is a temporary fix for some Intel HDMI codecs to avoid no sound output for
a resuming playback after S3.
After S3, the audio driver restores pin:cvt connection selections by
snd_hda_codec_resume_cache(). However this can happen before the gfx side is
ready and such connect selection is overlooked by HW. After gfx is ready, the
pins make the default selection again. And this will cause multiple pins share
a same convertor and mute control will affect each other. Thus a resumed audio
playback become silent after S3.
This patch verifies pin:cvt connection on preparing a stream, to assure the pin
selects the right convetor and an assigned convertor is not shared by other
unused pins. Apply this fix-up on Haswell, Broadwell and Valleyview (Baytrail).
We need this temporary fix before a reliable software communication channel is
established between audio and gfx, to sync audio/gfx operations.

For i350 VLAN stripping for VMs is not enabled in the VMOLR register but in
the DVMOLR register. Making the changes accordingly. It's not necessary to
unset the E1000_VMOLR_STRVLAN bit on i350 as the hardware will simply ignore
it.
Without this change if a VLAN is configured for a VF assigned to a guest
via (i.e.)
ip link set p1p1 vf 0 vlan 10
the VLAN tag will not be stripped from packets going into the VM. Which they
should be because the VM itself is not aware of the VLAN at all.

The current code would always return 0 for VLAN-encapsulated IP traffic.
One notable side effect was that VLAN traffic would never get prioritized
on OSD and OSX devices when priority queueing modes prio_queueing_tos or
prio_queueing_prec were enabled.

Commit f9c41a62bba3f3f7ef3541b2a025e3371bcbba97 introduced
a problem for SOCK_STREAM sockets, when only part of the
incoming iucv message is received by user space. In this
case the remaining data of the iucv message is lost.
This patch makes sure an incompletely received iucv message
is queued back to the receive queue.
