Josh Poimboeuf 8852c55240 kbuild: Fix objtool dependency for 'OBJECT_FILES_NON_STANDARD_<obj> := n' ... "OBJECT_FILES_NON_STANDARD_vma.o := n" has a dependency bug. When objtool source is updated, the affected object doesn't get re-analyzed by objtool. Peter's new variable-sized jump label feature relies on objtool rewriting the object file. Otherwise the system can fail to boot. That effectively upgrades this minor dependency issue to a major bug. The problem is that variables in prerequisites are expanded early, during the read-in phase. The '$(objtool_dep)' variable indirectly uses '$@', which isn't yet available when the target prerequisites are evaluated. Use '.SECONDEXPANSION:' which causes '$(objtool_dep)' to be expanded in a later phase, after the target-specific '$@' variable has been defined. Fixes: b9ab5ebb14 ("objtool: Add CONFIG_STACK_VALIDATION option") Fixes: ab3257042c ("jump_label, x86: Allow short NOPs") Reported-by: Matthew Wilcox <willy@infradead.org> Signed-off-by: Josh Poimboeuf <jpoimboe@redhat.com>		2021-05-19 15:07:20 -05:00
