+commit 263e45ccf27b21e9862cc538ed28978533d04e4b
+Author: Baoquan He <bhe@redhat.com>

+
+ Only print debug message when failed to serach for kernel symbol from /proc/kallsyms
+
+ Kernel symbol page_offset_base could be unavailable when mm KASLR code is
+ not compiled in kernel. It's inappropriate to print out error message
+ when failed to search for page_offset_base from /proc/kallsyms. Seems now
+ there is not a way to find out if mm KASLR is compiled in or not. An
+ alternative approach is only printing out debug message in get_kernel_sym
+ if failed to search a expected kernel symbol.
+
+ Do it in this patch, a simple fix.

+ Don't use %L width specifier with integer values
+
+ MUSL doesn't support %L except for floating-point arguments; therefore,
+ %ll must be used instead with integer arguments.
