Building kallsyms fails without CONFIG_PRINTK due to a missing
declaration:

  kernel/kallsyms.c: In function 'kallsyms_show_value':
  kernel/kallsyms.c:670:10: error: 'kptr_restrict' undeclared (first use in this function); did you mean 'keyring_restrict'?

This moves the declaration outside of the #ifdef guard, the definition
is already available without CONFIG_PRINTK.

This code goes back to the historical bitkeeper tree commit 3f7b0672086
("Module section offsets in /sys/module"), where Jonathan Corbet wanted
to show people how to debug loadable modules.

See

    https://lwn.net/Articles/88052/



from June 2004.

To expose the required load address information, Jonathan added the
sections subdirectory for every module in /sys/modules, and made them
S_IRUGO - readable by everybody.

It was a more innocent time, plus those S_IRxxx macro names are a lot
more confusing than the octal numbers are, so maybe it wasn't even
intentional.  But here we are, thirteen years later, and I'll just change
it to S_IRUSR instead.

Let's see if anybody even notices.

Merge /proc/kallsyms pointer value restrictions.

Instead of using %pK, and making it about root access (at the wrong
time, no less), make the whole choice of whether to show the actual
pointer value be very explicit to the kallsyms code.

In particular, we can now default to not doing so, and yet avoid
annoying kernel profiling by actually looking at whether kernel
profiling is allowed or not (by default it is not).

This is all mostly preparation for the real "let's stop leaking kernel
addresses" work that Tobin Harding is working on.

Small steps.

After refcnt reaches zero, vlan_vid_del() could free
dev->vlan_info via RCU:

	RCU_INIT_POINTER(dev->vlan_info, NULL);
	call_rcu(&vlan_info->rcu, vlan_info_rcu_free);

However, the pointer 'grp' still points to that memory
since it is set before vlan_vid_del():

        vlan_info = rtnl_dereference(dev->vlan_info);
        if (!vlan_info)
                goto out;
        grp = &vlan_info->grp;

Depends on when that RCU callback is scheduled, we could
trigger a use-after-free in vlan_group_for_each_dev()
right following this vlan_vid_del().

Fix it by moving vlan_vid_del() before setting grp. This
is also symmetric to the vlan_vid_add() we call in
vlan_device_event().

If the array is not present, assume all chip selects are native.  This
is the standard behavior for SPI masters configured via the device
tree and the behavior of this driver as well when it is configured via
device tree.

This reduces platform data vs DT differences and allows most of the
platform data based boards to remove their chip select arrays.

If the code that requests any chip select GPIOs fails, the cleanup of
spi_bitbang_start() by calling spi_bitbang_stop() is not done.  Add this
to the failure path.

Note that spi_bitbang_start() has to be called before requesting GPIOs
because the GPIO data in the spi master is populated when the master is
registed, and that doesn't happen until spi_bitbang_start() is called.

The driver will fail to load if no gpio chip selects are specified,
this patch changes this so that it no longer fails.

It's possible to use all native chip selects, in which case there is
no reason to have a gpio chip select array.  This is what happens if
the *optional* device tree property "cs-gpios" is omitted.

The spi core already checks for the absence of gpio chip selects in
the master and assigns any slaves the gpio_cs value of -ENOENT.

Also have the driver respect the standard SPI device tree property "num-cs"
to allow setting the number of chip selects without using cs-gpios.

This reverts commit 941f5f0f

.

Sadly, it turns out that we really can't just do the cross-CPU IPI to
all CPU's to get their proper frequencies, because it's much too
expensive on systems with lots of cores.

So we'll have to revert this for now, and revisit it using a smarter
model (probably doing one system-wide IPI at open time, and doing all
the frequency calculations in parallel).
