Summary

from fast one as dmabuf does not run callbacks from critical sections
since drm-kmod 5.7.
Consumers which requires fair irq_work like drm-kmod 5.4 must #define
LKPI_IRQ_WORK_USE_FAST_TQ somewhere in source file before linux/irq_work.h
inclusion to enable old behavior.

While here include linux/llist.h to get struct llist_node definition
and add TQFLG_FAILIF_PENDING flag to taskqueue_enqueue to match Linux.
