The driver has its own HID descriptor parsing code, that had and still
has several issues discovered by syzbot and other tools. Ideally we
should move the driver over to the HID subsystem, so that it uses proven
parsing code. However the devices in question are EOL, and GTCO is not
willing to extend resources for that, so let's simply remove the driver.
Note that our HID support has greatly improved over the last 10 years,
we may also consider reverting 6f8d9e26e7 ("hid-core.c: Adds all GTCO
CalComp Digitizers and InterWrite School Products to blacklist") and see
if GTCO devices actually work with normal HID drivers.

Simon reported an issue with the current scalar32_min_max_or() implementation.
That is, compared to the other 32 bit subreg tracking functions, the code in
scalar32_min_max_or() stands out that it's using the 64 bit registers instead
of 32 bit ones. This leads to bounds tracking issues, for example:

The bound tests on the map value force the upper unsigned bound to be 25769803777
in 64 bit (0b11000000000000000000000000000000001) and then lower one to be 1. By
using OR they are truncated and thus result in the range [1,1] for the 32 bit reg
tracker. This is incorrect given the only thing we know is that the value must be
positive and thus 2147483647 (0b1111111111111111111111111111111) at max for the
subregs. Fix it by using the {u,s}32_{min,max}_value vars instead. This also makes
sense, for example, for the case where we update dst_reg->s32_{min,max}_value in
the else branch we need to use the newly computed dst_reg->u32_{min,max}_value as
we know that these are positive. Previously, in the else branch the 64 bit values
of umin_value=1 and umax_value=32212254719 were used and latter got truncated to
be 1 as upper bound there. After the fix the subreg range is now correct:

Kernel threads intentionally do CLONE_FS in order to follow any changes
that 'init' does to set up the root directory (or cwd).
It is admittedly a bit odd, but it avoids the situation where 'init'
does some extensive setup to initialize the system environment, and then
we execute a usermode helper program, and it uses the original FS setup
from boot time that may be very limited and incomplete.
[ Both Al Viro and Eric Biederman point out that 'pivot_root()' will
follow the root regardless, since it fixes up other users of root (see
chroot_fs_refs() for details), but overmounting root and doing a
chroot() would not. ]
However, Vegard Nossum noticed that the CLONE_FS not only means that we
follow the root and current working directories, it also means we share
umask with whatever init changed it to. That wasn't intentional.
Just reset umask to the original default (0022) before actually starting
the usermode helper program.

The first thing that the ftrace function callback helper functions should do
is to check for recursion. Peter Zijlstra found that when
"rcu_is_watching()" had its notrace removed, it caused perf function tracing
to crash. This is because the call of rcu_is_watching() is tested before
function recursion is checked and and if it is traced, it will cause an
infinite recursion loop.
rcu_is_watching() should still stay notrace, but to prevent this should
never had crashed in the first place. The recursion prevention must be the
first thing done in callback functions.

The temp buffer size variable for trace_find_next_entry() was incorrectly
being updated when the size did not change. The temp buffer size should only
be updated when it is reallocated.
This is mostly an issue when used with ftrace_dump(). That's because
ftrace_dump() can not allocate a new buffer, and instead uses a temporary
buffer with a fix size. But the variable that keeps track of that size is
incorrectly updated with each call, and it could fall into the path that
would try to reallocate the buffer and produce a warning.

Pull networking fixes from Jakub Kicinski:
- fix failure to add bond interfaces to a bridge, the offload-handling
code was too defensive there and recent refactoring unearthed that.
Users complained (Ido)
- fix unnecessarily reflecting ECN bits within TOS values / QoS marking
in TCP ACK and reset packets (Wei)
- fix a deadlock with bpf iterator. Hopefully we're in the clear on
this front now... (Yonghong)
- BPF fix for clobbering r2 in bpf_gen_ld_abs (Daniel)
- fix AQL on mt76 devices with FW rate control and add a couple of AQL
issues in mac80211 code (Felix)
- fix authentication issue with mwifiex (Maximilian)
- WiFi connectivity fix: revert IGTK support in ti/wlcore (Mauro)
- fix exception handling for multipath routes via same device (David
Ahern)
- revert back to a BH spin lock flavor for nsid_lock: there are paths
which do require the BH context protection (Taehee)
- fix interrupt / queue / NAPI handling in the lantiq driver (Hauke)
- fix ife module load deadlock (Cong)
- make an adjustment to netlink reply message type for code added in
this release (the sole change touching uAPI here) (Michal)
- a number of fixes for small NXP and Microchip switches (Vladimir)
[ Pull request acked by David: "you can expect more of this in the
future as I try to delegate more things to Jakub" ]

Pull tracing fixes from Steven Rostedt:
- Check kprobe is enabled before unregistering from ftrace as it isn't
registered when disabled.
- Remove kprobes enabled via command-line that is on init text when
freed.
- Add missing RCU synchronization for ftrace trampoline symbols removed
from kallsyms.
- Free trampoline on error path if ftrace_startup() fails.
- Give more space for the longer PID numbers in trace output.
- Fix a possible double free in the histogram code.
- A couple of fixes that were discovered by sparse.

Pull RCU fix from Paul McKenney:
"This contains a single commit that fixes a bug that was introduced in
the last merge window. This bug causes a compiler warning complaining
about show_rcu_tasks_classic_gp_kthread() being an unused static
function in !SMP kernels.
The fix is straightforward, just adding an 'inline' to make this a
static inline function, thus avoiding the warning.
This bug was reported by Laurent Pinchart, who would like it fixed
sooner rather than later"
* 'rcu/urgent' of git://git.kernel.org/pub/scm/linux/kernel/git/paulmck/linux-rcu:
rcu-tasks: Prevent complaints of unused show_rcu_tasks_classic_gp_kthread()
Fix this link error:
ERROR: modpost: "rcu_idle_enter" [drivers/acpi/processor.ko] undefined!
ERROR: modpost: "rcu_idle_exit" [drivers/acpi/processor.ko] undefined!
when CONFIG_ACPI_PROCESSOR is built as module. PeterZ says that in light
of ARM needing those soon too, they should simply be exported.

Commit 32927393dc ("sysctl: pass kernel pointers to ->proc_handler")
changed ctl_table.proc_handler to take a kernel pointer. Adjust the
signature of stack_erasing_sysctl to match ctl_table.proc_handler which
fixes the following sparse warning:
kernel/stackleak.c:31:50: warning: incorrect type in argument 3 (different address spaces)
kernel/stackleak.c:31:50: expected void *
kernel/stackleak.c:31:50: got void [noderef] __user *buffer
