The sequence number counter is incremented on each output buffer, and that
incremented value is used as the sequence number of that buffer. The input
buffer sequence numbering is based just on reading the same counter. If
the input buffer is marked done first, its sequence number ends up being
that of the output buffer - 1.
This is how the resizer works as well.

use the vb2_buffer_state enum for assigning the state
of the vb2 buffer, along side making isp_pipeline_state
state variable local to the block.
This fixes the following sparse warning as well:

The Media Control framework now requires entities to be registered with
the media device before creating links so commit c7621b3044f7 ("[media]
v4l: vsp1: separate links creation from entities init") separated link
creation from entities init.
But unfortunately that patch introduced a regression since wrong links
were created causing a boot failure on Renesas boards.
This patch fixes the boot issue and also the media graph was compared
by Geert Uytterhoeven to make sure that the driver changes required by
the Media Control framework next generation did not affect the graph.

An attempt at not spreading out the file_priv->event_space stuff out

This patch extends commit b93d6471748d ("sctp: implement the sender side
for SACK-IMMEDIATELY extension") as it didn't white list
SCTP_SACK_IMMEDIATELY on sctp_msghdr_parse(), causing it to be
understood as an invalid flag and returning -EINVAL to the application.
Note that the actual handling of the flag is already there in
sctp_datamsg_from_user().

The napi_synchronize() function is defined twice: The definition
for SMP builds waits for other CPUs to be done, while the uniprocessor
variant just contains a barrier and ignores its argument.
In the mvneta driver, this leads to a warning about an unused variable
when we lookup the NAPI struct of another CPU and then don't use it:
ethernet/marvell/mvneta.c: In function 'mvneta_percpu_notifier':
ethernet/marvell/mvneta.c:2910:30: error: unused variable 'other_port' [-Werror=unused-variable]
There are no other CPUs on a UP build, so that code never runs, but
gcc does not know this.
The nicest solution seems to be to turn the napi_synchronize() helper
into an inline function for the UP case as well, as that leads gcc to
not complain about the argument being unused. Once we do that, we can
also combine the two cases into a single function definition and use
if(IS_ENABLED()) rather than #ifdef to make it look a bit nicer.
The warning first came up in linux-4.4, but I failed to catch it
earlier.

Several times already this has been reported as kasan reports caused by
syzkaller and trinity and people always looked at RCU races, but it is
much more simple. :)
In case we bind a pptp socket multiple times, we simply add it to
the callid_sock list but don't remove the old binding. Thus the old
socket stays in the bucket with unused call_id indexes and doesn't get
cleaned up. This causes various forms of kasan reports which were hard
to pinpoint.
Simply don't allow multiple binds and correct error handling in
pptp_bind. Also keep sk_state bits in place in pptp_connect.

With commit 90a545e9 (restrict /dev/mem to idle io memory ranges) mapping
rtas_rmo_buf from user space is failing. Hence we are not able to make
RTAS syscall.
This patch calls page_is_rtas_user_buf before calling iomem_is_exclusive
in devmem_is_allowed(). This will allow user space to map rtas_rmo_buf
and we are able to make RTAS syscall.

In function usb_reset_and_verify_device, the old BOS descriptor may
still be used before allocating a new one. (usb_unlocked_disable_lpm
function uses it under the situation that it fails to disable lpm.)
So we cannot set the udev->bos to NULL before that, just keep what it
was. It will be overwrite when allocating a new one.

In current acm driver, the bulk-in callback function ignores the
URBs unlinked in usb core.
This causes unexpected data loss in some cases. For example,
runtime suspend entry will unlinked all urbs and set urb->status

Hence, data loss occurs.
This patch lets bulk-in callback function handle unlinked urbs

This patch fixes compile time warnings when CONFIG_PM_SLEEP
is undefined. In this case sleep related counters are unused.

If we detect that there is nothing to do just set the flag and do not
check if it was already set before. Races really do not matter. If the
flag is set by any code then the shepherd will start dealing with the
situation and reenable the vmstat workers when necessary again.
Since commit 0eb77e988032 ("vmstat: make vmstat_updater deferrable again
and shut down on idle") quiet_vmstat might update cpu_stat_off and mark
a particular cpu to be handled by vmstat_shepherd. This might trigger a
VM_BUG_ON in vmstat_update because the work item might have been
sleeping during the idle period and see the cpu_stat_off updated after
the wake up. The VM_BUG_ON is therefore misleading and no more
appropriate. Moreover it doesn't really suite any protection from real
bugs because vmstat_shepherd will simply reschedule the vmstat_work
anytime it sees a particular cpu set or vmstat_update would do the same
from the worker context directly. Even when the two would race the
result wouldn't be incorrect as the counters update is fully idempotent.

As most platforms implement the PROM serial interface prom_putchar()
add a simple bridge to allow re-using this code for zboot.

Add dummy.o to the targets list, and fill targets automatically from
$(vmlinuzobjs) to avoid having to maintain two lists.
When building with XZ compression copy ashldi3.c to the build
directory to use a different object file for the kernel and zboot.
Without this the same object file need to be build with different
flags which cause a rebuild at every run.

The extended flash address needs to be subtracted from bcm_tag flash
image offsets. Move this value to the bcm_tag header file.
Renamed define name to consistently use bcm963xx for flash layout
which should be considered a property of the board and not the SoC
(i.e. bcm63xx could theoretically be used on a board without CFE
or any flash).
