Subject: coredump: update coredump-related headers
X-Git-Tag: next-20120907~1^2~26
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=73e11a7d66e19d30898fb354e5a766f0d05e8f93;p=karo-tx-linux.git

coredump: update coredump-related headers

Create a new header file, fs/coredump.h, which contains functions only
used by the new coredump.c.  It also moves do_coredump to the
include/linux/coredump.h header file, for consistency.
