#     Merge branch 'for-5.4-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/cgroup
#     
#     Pull cgroup fix from Tejun Heo:
#      "There's an inadvertent preemption point in ptrace_stop() which was
#       reliably triggering for a test scenario significantly slowing it down.
#     
#       This contains Oleg's fix to remove the unwanted preemption point"
#     
#     * 'for-5.4-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/cgroup:
#       cgroup: freezer: call cgroup_enter_frozen() with preemption disabled in ptrace_stop()

WARNING: vmlinux.o(.text.unlikely+0x610): Section mismatch in reference from the function free_memmap() to the function .meminit.text:memblock_free()
The function free_memmap() references
the function __meminit memblock_free().
This is often because free_memmap lacks a __meminit 
annotation or the annotation of memblock_free is wrong.
