+# Rel. commit "objtool: Always fail on fatal errors" (Josh Poimboeuf, 31 Mar 2025)
|
|
+# This is a *ugly* hack to disable objtool during the final processing of wl.o.
|
|
+# Since is embeds the proprietary blob (wlc_hybrid.o_shipped), objtool can't
|
|
+# process it, as it does not follow the requirements of current kernels,
|
|
+# including support for critical security features. As of Linux v6.15+, it causes
|
|
+# a build error. Disable it, at your own risk. Note the MIT license applies:
