This was added to the kernel code in <1658d35ead5d> ("list: Use
READ_ONCE() when testing for empty lists").
There's nothing special we need to do about it in userspace.

It seems that newer gcc complains about lack of explicit declaration for some
of the API we use, add it in.

These were added to the kernel code in cee34d88c ("lockdep: Fix a race between
/proc/lock_stat and module unload"). There's nothing special we need to do
about them in userspace.

Recent changes to rbtree.h may break compilation. There is no
reason to use a liblockdep specific header to begin with, so
we'll use the one shared with all other tools/.

As Peter Zijlstra pointed out, the varargs for WARN() are
optional, so we need to correctly handle the case where they
don't exist.
This would cause a compilation error.

Recent changes to kernel/locking/lockdep.c broke the liblockdep build. Fix
that.

Combine all definitions into a common tools/include/linux/types.h and
kill the wild growth elsewhere. Move DECLARE_BITMAP to its proper
bitmap.h header.

So tools/ has been growing three, at a different stage of their
development export.h headers and so we should unite into one. Add
tools/include/ to the include path of virtio and liblockdep to pick the
shared header now.

Commit 63f9a7fde7 "asmlinkage: Make lockdep_sys_exit asmlinkage" has added
asmlinkage annotation to lockdep_sys_exit, which broke build of liblockdep.
Since we don't need asmlinkage in liblockep, just ignore it.

Commit 71ae8aac ("lib: introduce arch optimized hash library")
added an include to <linux/hash.h> for setting up an architecture
specific fast hash.
This patch mirrors the fix used for perf, titled "tools: perf: util: fix
include for non x86 architectures".

kernel/locking/lockdep.c deals with validating locking scenarios for
various architectures supported by the kernel. There isn't
anything kernel specific going on in lockdep, and when we
compare userspace to other architectures that don't have to deal
with irqs such as s390, they become all too similar.
We wrap kernel/locking/lockdep.c and include/linux/lockdep.h with
several headers which allow us to build and use lockdep from
userspace. We don't touch the kernel code itself which means
that any work done on lockdep in the kernel will automatically
benefit userspace lockdep as well!
