mainline inclusion from mainline-v5.4 commit 8af0c18af1425fc70686c0fdcfc0072cd8431aa0 category: feature bugzilla: https://gitee.com/openeuler/kernel/issues/I47QS2 CVE: NA
--------------------------------
kthread.h can't be included in psi_types.h because it creates a circular inclusion with kthread.h eventually including psi_types.h and complaining on kthread structures not being defined because they are defined further in the kthread.h. Resolve this by removing psi_types.h inclusion from the headers included from kthread.h.
