In sync with the main kernel headers, include a stub version of
compiler-context-analysis.h in tools/include/linux/compiler_types.h and
remove the sparse context tracking definitions.
Since tools/ headers are generally self-contained, provide a standalone
tools/include/linux/compiler-context-analysis.h with no-op stubs for now. Also
clean up redundant stubs in tools/testing/shared/linux/kernel.h that are now
redundant.
This fixes build errors in tools/testing/radix-tree/ where headers from
include/linux/ (like cleanup.h) are used directly and expect these
macros to be defined:
| cc -I../shared -I. -I../../include -I../../arch/x86/include -I../../../lib -g -Og -Wall -D_LGPL_SOURCE -fsanitize=address -fsanitize=undefined -c -o radix-tree.o radix-tree.c

The shared userspace logic used for unit-testing maple tree and VMA code
currently has its own replacements for atomics helpers. This is not
needed as the necessary APIs already have userspace implementations in the
tools tree. Switching over to that allows deleting a bit of code.
Note that the implementation is different; while the version being deleted
here is implemented using liburcu, the existing version in tools uses
either x86 asm or compiler builtins. It's assumed that both are equally
likely to be correct.
The tools tree's version of atomic_t is a struct type while the version
being deleted was just a typedef of an integer. This means it's no longer
valid to call __sync_bool_compare_and_swap() directly on it. One option
would be to just peek into the struct and call it on the field, but it
seems a little cleaner to just use the corresponding atomic.h API whic has
been added recently. Now the fake mapping_map_writable() is copied from
the real one.

Commit 857d18f23a ("cleanup: Introduce ACQUIRE() and ACQUIRE_ERR() for
conditional locks") accidentally broke the radix tree, VMA userland tests
by including linux/args.h which is not present in the tools/include
directory.
This patch copies this over and adds an #ifdef block to avoid duplicate
__CONCAT declaration in conflict with system headers when we ultimately
include this.

Patch series "lib/interval_tree: add some test cases and cleanup", v2.
Since rbtree/augmented tree/interval tree share similar data structure,
besides new cases for interval tree, this patch set also does cleanup for
others.
This patch (of 7):
Currently we have some tests for rbtree related data structure, e.g.
rbtree, augmented rbtree, interval tree, in lib/ as kernel module.
To facilitate the test and debug for those fundamental data structure,
this patch enable those tests in userland.
