Finally, move the last thermal zone sysfs attributes to
tz->device.groups: trips attributes. This requires adding a
attribute_group to thermal_zone_device, creating it dynamically, and
then setting all trips attributes in it. The trips attribute is then
added to the tz->device.groups.
As the removal of all attributes are handled by device core, the device
remove calls are not needed anymore.

This patch moves the passive attribute to tz->device.groups. Moving the

Thermal zones attributes are all being created using
device_create_file(). This has the disadvantage of making the code
complicated and sometimes we may miss the cleanup of them.
This patch starts to move the thermal zone sysfs attributes to the
dev.groups, so Linux device core manage them for us. For now, this patch
only moves those attributes are always present regardless of thermal
zone condition.
This change has also the advantage of cleaning up the thermal zone
parameters sysfs entries that are left unclean after device
registration.

The PF_EXITING check in task_wants_autogroup() is no longer needed. Remove
it, but see the next patch.
However the comment is correct in that autogroup_move_group() must always
change task_group() for every thread so the sysctl_ check is very wrong;
we can race with cgroups and even sys_setsid() is not safe because a task
running with task_group() == ag->tg must participate in refcounting:
int main(void)
{
int sctl = open("/proc/sys/kernel/sched_autogroup_enabled", O_WRONLY);
assert(sctl > 0);
if (fork()) {
wait(NULL); // destroy the child's ag/tg
pause();
}
assert(pwrite(sctl, "1\n", 2, 0) == 2);
assert(setsid() > 0);
if (fork())
pause();
kill(getppid(), SIGKILL);
sleep(1);
// The child has gone, the grandchild runs with kref == 1
assert(pwrite(sctl, "0\n", 2, 0) == 2);
assert(setsid() > 0);
// runs with the freed ag/tg
for (;;)
sleep(1);
return 0;
}
crashes the kernel. It doesn't really need sleep(1), it doesn't matter if
autogroup_move_group() actually frees the task_group or this happens later.

Watchdog device in Intel Tangier relies on SCU to be present. It uses the SCU
IPC channel to send commands and receive responses. If watchdog driver is
initialized quite before SCU and a command has been sent the result is always
an error like the following:
intel_mid_wdt: Error stopping watchdog: 0xffffffed
Register watchdog device whne SCU is ready to avoid described issue.

Robert O'Callahan reported that after an execve PTRACE_GETREGSET
NT_X86_XSTATE continues to return the pre-exec register values
until the exec'ed task modifies FPU state.
The test code is at:
https://bugzilla.redhat.com/attachment.cgi?id=1164286.
What is happening is fpu__clear() does not properly clear fpstate.
Fix it by doing just that.
