+Subject: [PATCH] elf: Fix hwcaps string size overestimation
+
+Conflict:NA
+Reference:https://sourceware.org/git/?p=glibc.git;a=commit;h=a23820f6052a740246fdc7dcd9c43ce8eed0c45a
+
+Commit dad90d528259b669342757c37dedefa8577e2636 added glibc-hwcaps
+support for LD_LIBRARY_PATH and, for this, it adjusted the total
+string size required in _dl_important_hwcaps. However, in doing so
+it inadvertently altered the calculation of the size required for
+the power set strings, as the computation of the power set string
+size depended on the first value assigned to the total variable,
+which is later shifted, resulting in overallocation of string
+space. Fix this now by using a different variable to hold the
+string size required for glibc-hwcaps.
