Subject: [PATCH v5 0/6] Unload linux/kernel.h

kernel.h hosts declarations that can be placed better. This series
decouples kernel.h with some explicit and implicit dependencies; also,
moves tracing functionality to a new independent header.

For testing, see v4.

v4: https://lore.kernel.org/all/20251225170930.1151781-1-yury.norov@gmail.com/
v5:
 - drop v4#7, i.e. keep trace_printk.h included in kernel.h

Steven Rostedt (1):
  tracing: Remove size parameter in __trace_puts()

Yury Norov (5):
  kernel.h: drop STACK_MAGIC macro
  moduleparam: include required headers explicitly
  kernel.h: move VERIFY_OCTAL_PERMISSIONS() to sysfs.h
  kernel.h: include linux/instruction_pointer.h explicitly
  tracing: move tracing declarations from kernel.h to a dedicated header
