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 | In file included from ../shared/linux/cleanup.h:2, | from ../shared/linux/../../../../include/linux/idr.h:18, | from ../shared/linux/idr.h:5, | from radix-tree.c:18: | ../shared/linux/../../../../include/linux/idr.h: In function ‘class_idr_alloc_destructor’: | ../shared/linux/../../../../include/linux/cleanup.h:283:9: error: expected declaration specifiers before ‘__no_context_analysis’ | 283 | __no_context_analysis \ | | ^~~~~~~~~~~~~~~~~~~~~ Closes: https://lore.kernel.org/oe-lkp/202601261546.d7ae2447-lkp@intel.com Reported-by: kernel test robot <oliver.sang@intel.com> Signed-off-by: Marco Elver <elver@google.com> Signed-off-by: Peter Zijlstra (Intel) <peterz@infradead.org> Reviewed-by: Lorenzo Stoakes <lorenzo.stoakes@oracle.com> Tested-by: Lorenzo Stoakes <lorenzo.stoakes@oracle.com> Link: https://patch.msgid.link/20260127111428.3747328-1-elver@google.com
