Subject: [PATCH v2 0/2] lib/vsprintf: introduce stricter rules for %p extensions

Besides the code refactoring we introduce the following rules for %p extensions
here. i.e:

- fixed type extensions are always printed in hex format, prefixed by '0x',
  small letters, full field width on a running architecture (%pa[dp], %pNF)

- fallback to %p based on different kernel configuration will be under the same
  rule set as for fixed types above (%pCn when COMMON_CLK=n, %p[FfSsB] when
  KALLSYMS=n)

- fallback to %p of unimplemented extension will be under the same rule set as
  for fixed types above (%pN)

Since v1:
 - address comments from Joe and Rasmums (might be not all of them)
 - add patch 2
 - desribe in cover letter what is done besides refactoring

Andy Shevchenko (2):
  lib/vsprintf: refactor duplicate code to special_hex_number()
  lib/vsprintf: factor out %pN[F] handler as netdev_bits()
