Subject: [PATCH] memblock: Neaten logging
Use more typical kernel logging styles.
o Add and use #define pr_fmt KBUILD_MODNAME ": " fmt
o Neaten memblock_dbg to use %s: %pS: to output __func__ and caller
o Convert existing uses of pr_<level> and memblock_dbg appropriately
Logging output is now always prefixed with 'memblock: '
Debugging output is now prefixed with 'memblock: ', function and caller
Signed-off-by: Joe Perches <joe@...ches.com>
