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 3f7b0672 ("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. * kallsyms-restrictions: stop using '%pK' for /proc/kallsyms pointer values

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).
