+    rhel8 only patch
+
+    Since we reverted to the implementation used in crash-7.2.3-17.el8 for
+    arm64 52-bit changes (see 'crash/arm64: Revert to implementation used
+    in crash-7.2.3-17.el8  [Support for CONFIG_ARM64_USER_VA_BITS_52 and
+    CONFIG_ARM64_PA_BITS=52]' for details), add the missing QUIET argument
+    if the read access to the 'idmap_ptrs_per_pgd' symbol failed.
+    
+    This will do away with the warning message we get in case the
+    'idmap_ptrs_per_pgd' symbol is not found via readmem().
