+Subject: ice: mark ice_write_prof_mask_reg() as noinline
+
+The following happens during build:
+
+```
+drivers/net/ethernet/intel/ice/ice.o: error: objtool: ice_free_prof_mask.isra.0() falls through to next function ice_free_flow_profs.cold()
+drivers/net/ethernet/intel/ice/ice.o: error: objtool: ice_free_prof_mask.isra.0.cold() is missing an ELF size annotation
+```
+
+Marking ice_write_prof_mask_reg() as noinline solves this, although I'm
+not sure if this is a proper solution. Apparently, this happens with -O3
+only, the `default` case is never reachable, but the optimiser generates
+branching to a random code location.

+Subject: wifi: mac80211: mark copy_mesh_setup() as noinline
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+With -O3 and GCC v15.1, the following happens:
+
+```
+In function ‘fortify_memcpy_chk’,
+    inlined from ‘copy_mesh_setup’ at net/mac80211/cfg.c:2541:2,
+    inlined from ‘ieee80211_join_mesh’ at net/mac80211/cfg.c:2694:8:
+./include/linux/fortify-string.h:571:25: warning: call to ‘__write_overflow_field’ declared with attribute warning: detected write beyond size of field (1st parameter); maybe use struct_group()? [-Wattribute-warning]
+```
+
+Maybe, it's time to abandon -O3 altogether?
