+    stdlib/test-bz22786: Avoid spurious test failures using alias mappings
+    
+    On systems without enough random-access memory, stdlib/test-bz22786
+    will go deeply into swap and time out, even with a substantial
+    TIMEOUTFACTOR.  This commit adds a facility to construct repeating
+    strings with alias mappings, so that the requirement for physical
+    memory, and uses it in stdlib/test-bz22786.
+
+Adjusted here for conflicts due to the previous support/ backport in
+glibc-rh1638523-1.patch.
