Subject: [PATCH 1/2] kernel.h: add pr_<level>_hex_dump macros
Add macros e.g. named pr_<level>_hex_dump calling print_hex_dump with
the approriate level, with level beeing emerg, alert, ..., debug. This
is similiar to the functions starting with "pr_".
The parameters for those macros are the same as for print_hex_dump
excluding the level.
