This tiny series introduces functionality for either convertion a blob of data to "hex ASCII" in memory or direct printing in stdout.
The first patch is required to safe existing users of dummy blobs (as of today) that will become a real functions.
Note even though entire series is tagges as v2

Alexey Brodkin (2): linux-compat: Use original kern_levels.h for kernel debug levels lib: Add hexdump
Changes v1 -> v2: * Introduced linux/kern_levels.h so KERNEL_XXX symbols are really defined * Move hexdump definitions to a separate header. * Move helper funcions to the header so they might be used even if CONFIG_HEXDUMP is not enabled and if not used they will not occupy extra bytes of memory being "static inline" ones. * While at it replace its own hex_asc[], hex_asc_{lo|hi}() and pack_hex_byte() in lib/vsprintf.c with generic ones from hexdump. * In print_hex_dump() revert back first parametr for debug level, otherwise existing users of the function will be broken.
