staging: comedi: s626: remove encpriv macro

The `encpriv` macro relies on a local variable `dev` (of type `struct
comedi_device *`) being set correctly.  By a convoluted path involving
the `private` data pointer of subdevice 5 (the encoder (counter)
subdevice), the macro always yields a pointer to the first element of
the static array `enc_private_data[]`.  That holds statically constant
data for each of 6 encoder channels.

Instead of using the `encpriv` macro, just access the array it points to
directly and get rid of the macro.  Don't bother initializing the
`private` member of the encoder subdevice any more.  Since
`enc_private_data[]` now has nothing to so with subdevice private data,
rename `enc_private_data[]` to `s626_enc_chan_info[]` and rename its
type from `struct enc_private` to `struct s626_enc_info`.  Since the
array contains unchanging, static information, declare it `const` and
declare all the variables that point to it `const`.

A forward declaration of `s626_enc_chan_info[]` has been added
temporarily and will be removed by a later patch.

staging: ktap: add to the kernel tree

This patch introduces ktap to staging tree.

ktap is a new script-based dynamic tracing tool for Linux,
it uses a scripting language and lets users trace the
Linux kernel dynamically. ktap is designed to give
operational insights with interoperability that allow
users to tune, troubleshoot and extend kernel and application.
It's similar with Linux Systemtap and Solaris Dtrace.

ktap have different design principles from Linux mainstream
dynamic tracing language in that it's based on bytecode,
so it doesn't depend upon GCC, doesn't require compiling
kernel module for each script, safe to use in production
environment, fulfilling the embedded ecosystem's tracing needs.

See ktap tutorial for more information:
    http://www.ktap.org/doc/tutorial.html

The merit of putting this software in staging tree is
to make it more possible to get feedback from users
and thus polish the code.

staging: comedi: avoid memleak for subdevice private

`comedi_alloc_spriv()` allocates private storage for a comedi subdevice
and sets the `SRF_FREE_SPRIV` flag in the `runflags` member of the
subdevice to allow the private storage to be automatically freed when
the comedi device is being cleaned up.  Unfortunately, the flag gets
clobbered by `do_cmd_ioctl()` which calls
`comedi_set_subdevice_runflags()` with a mask value `~0` and only the
`SRF_USER` and `SRF_RUNNING` flags set, all the other SRF flags being
cleared.

Change the calls to `comedi_set_subdevice_runflags()` that currently use
a mask value of `~0` to use a more relevant mask value.  For
`do_cmd_ioctl()`, the relevant SRF flags are `SRF_USER`, `SRF_ERROR` and
`SRF_RUNNING`.  (At one time, `SRF_RT` would be included in that set of
flags, but it is no longer used.)  For `comedi_alloc_spriv()` replace
the call to `comedi_set_subdevice_runflags()` with a simple
OR-assignment to avoid unnecessary use of a spin-lock.

driver has ever set it; it's just been left at its initial value of 0.

staging: comedi: remove unused 'channel flags' support

The `flags` and `flaglist` members of `struct comedi_subdevice` were
defined to supply "all-channel" flags via the `COMEDI_SUBDINFO` ioctl,
or "channel-specific" flags via the `COMEDI_CHANINFO` ioctls,
respectively.  However, no comedi driver has ever set them.

It's not entirely clear how "all-channel" flags would differ from the
"subdevice" flags passed by `COMEDI_SUBDINFO`.  It is conceivable that
"channel-specific" flags could be used to describe different analog
reference values (or whatever) supported by different channels.
Presumably these would use some sub-set of the `SDF_xxx` subdevice flag
values, or possibly the `CR_xxx` flag values that get packed into a
"chanspec" value (along with a channel number and range code).  The
original intentions are lost in the mists of time.

For now, just remove the `flags` and `flaglist` members from `struct
comedi_subdevice` and behave as though they have been left at their
default values (0 or NULL) by the low-level comedi driver.

staging: octeon-ethernet: allow to set IRQ smp_affinity freely

Currently the driver assumes that CPU 0 is handling all the hard IRQs.
This is wrong in Linux SMP systems where user is allowed to assign to
hardware IRQs to any CPU. The driver will stop working if user sets
smp_affinity so that interrupts end up being handled by other than CPU
0. The patch fixes that.
