+Subject: [PATCH 06/39] [RISC-V] Fix parsing flags in ELF64 files.
+
+When ldconfig reads Elf64 files to determine the ABI, it used the
+Elf32 type, so read the wrong location, and stored the wrong ABI
+type in the cache, making the cache useless.  This patch uses
+an Elf64 type for Elf64 objects instead.
+
+Note that pre-patch caches might need to be manually removed and
+regenerated to get the correct ABIs stored.
+
+       [BZ #22827]
+       * sysdeps/unix/sysv/linux/riscv/readelflib.c (process_elf_file): Use
+       64-bit ELF type for 64-bit ELF objects.
+
+(cherry picked from commit 6a1ff640dcec04905d8518983ad6252d38b7a733)
