This does all the RCU magic inside of it. The caller must call put_cred() on
the credentials so obtained when they're finished with.
[*] Note: The result of __task_cred() should not be passed directly to

There are a couple of convenience functions to access bits of another task's
credentials, hiding the RCU magic from the caller:

s4_nonvs prevents the kernel from saving/restoring the
ACPI NVS memory during hibernation.
nonvs prevents the kernel from saving/restoring the
ACPI NVS memory during suspend/hibernation and resume.
sci_force_enable causes the kernel to set SCI_EN directly
on resume from S1/S3 (which is against the ACPI spec,
but some broken systems don't work without it).
