There are three approach to solve it:

2. modify the cscope emacs plugin lisp code;
3. modify the Makefile;
I have tried to communicate with the cscope upstream, but later I
realize the third approach is most meaningful.

switch (cmd) {

case WDIOC_GETSTATUS:
case WDIOC_GETBOOTSTATUS:
case WDIOC_GETTEMP:
case WDIOC_SETOPTIONS:

labels.

[WATCHDOG] mpc8xxx_wdt: add support for MPC8xx watchdogs
The mpc8xxx_wdt driver is using two registers: SWSRR to push magic
numbers, and SWCRR to control the watchdog. Both registers are available
on the MPC8xx, and seem to have the same offsets and semantics as in
MPC83xx/MPC86xx watchdogs. The only difference is prescale value. So
this driver simply works on the MPC8xx CPUs.
One quirk is needed for the MPC8xx, though. It has small prescale value
and slow CPU, so the watchdog resets board prior to the driver has time to
load. To solve this we should split initialization in two steps: start
ping the watchdog early, and register the watchdog userspace interface
later.
MPC823 seem to be the first CPU in MPC8xx line, so we use fsl,mpc823-wdt
compatible matching.

On MPC86xx the watchdog could be enabled only at power-on-reset, and could

MPC83xx CPUs are only differ in a way that watchdog could be disabled
once, but after it was enabled via software it becomes just the same as
MPC86xx.
Thus, to support MPC86xx I added the kernel timer which pings the watchdog
until the userspace opens it.
Since we implemented the timer, now we're able to implement proper
handling for the CONFIG_WATCHDOG_NOWAYOUT case, for MPC83xx and MPC86xx.
Also move the probe code into subsys_initcall, because we want start

cciss: remove redundant code
This patch removes redundant code where ever logical volumes are added or
removed. It adds 3 new functions that are called instead of having the same
code spread throughout the driver. It also removes the cciss_getgeometry
function.
The patch is fairly complex but we haven't figured out how to make it any
simpler and still do everything that needs to be done. Some of the
complexity comes from having to special case booting from cciss. Otherwise
the gendisk doesn't get added in time and the switchroot will fail.

cciss: make rebuild_lun_table behave better
This patch makes the rebuild_lun_table smart enough to not rip a logical
volume out from under the OS. Without this fix if a customer is running
hpacucli to monitor their storage the driver will blindly remove and re-add
the disks whenever the utility calls the CCISS_REGNEWD ioctl. Unfortunately,
both hpacucli and ACUXE call the ioctl repeatedly. Customers have reported
IO coming to a standstill. Calling the ioctl is the problem, this patch is
the fix.

PXA suspend switches off DMA core, which loses all context

That regression was not root-caused by the original commit, it was just
uncovered by it, and the real fix was done by Alan Stern in commit 580da34847488b404218d1d7f53b156f245f5555 ("Fix USB storage hang on
command abort").
We can thus re-introduce the change that was confirmed by Alan Jenkins
to be still required by his odd card reader.

Based upon original patch by Herbert Xu, which contained
the following problem description:
--------------------
When the forward delay is set to zero, we still delay the setting
of the forwarding state by one or possibly two timers depending
on whether STP is enabled. This could either turn out to be
instantaneous, or horribly slow depending on the load of the
machine.
As there is nothing preventing us from enabling forwarding straight
away, this patch eliminates this potential delay by executing the
code directly if the forward delay is zero.
The effect of this problem is that immediately after the carrier
comes on a port, the bridge will drop all packets received from
that port until it enters forwarding mode, thus causing unnecessary
packet loss.
Note that this patch doesn't fully remove the delay due to the
link watcher. We should also check the carrier state when we
are about to drop an incoming packet because the port is disabled.
But that's for another patch.
--------------------
This version of the fix takes a different approach, in that
it just does the state change directly.

Hugh adds: in fact, none of find_vma_prepare's callers use those values
when a vma is found to be already covering addr, it's either an error or
an occasion to munmap and repeat. Okay, let's quieten the compiler (but I
would prefer it if pprev, rb_link and rb_parent were meaningful in that
case, rather than whatever's in them from descending the tree).
