kobject_init_and_add() takes reference even when it fails.
In nilfs_sysfs_create_device_group(), the memory allocated by
kobject_init_and_add() is not freed when kobject_init_and_add()
fails. Fix this issue by calling kobject_put() to clean up the
kobject.

If the kernel erroneously allows WRGSBASE and user code writes a
negative value, paranoid_entry will get confused. Check for this by
writing a negative value to GSBASE and doing SYSENTER with TF set.
A successful run looks like:

This patch modifies perf_probe_msr() by allowing passing of
struct perf_msr array where some entries are not populated, i.e.,
they have either an msr address of 0 or no attribute_group pointer.
This helps with certain call paths, e.g., RAPL.

This patch modifies the default visibility of the attribute_group
for each RAPL event. By default if the grp.is_visible field is NULL,
then sysfs considers that it must display the attribute group.
If the field is not NULL (callback function), then the return value

Instead of having two sets of kmem_caches: one for system-wide and

Obj_cgroup API provides an ability to account sub-page sized kernel

Currently, the root cgroup does not have a cpu.stat file. Add one which
is consistent with /proc/stat to capture global cpu statistics that

Add thermal sensor support for r8a7742 SoC. The Renesas RZ/G1H

No driver change is needed due to the fallback compatible value
