Subject: [PATCH v3] staging: lustre: libcfs: fix sparse warnings about static
 declaration

Fixes the following sparse warnings:

drivers/staging/lustre/lustre/libcfs/linux/linux-prim.c:198:1: warning:
 symbol 'libcfs_arch_init' was not declared. Should it be static?
drivers/staging/lustre/lustre/libcfs/linux/linux-prim.c:204:1: warning:
 symbol 'libcfs_arch_cleanup' was not declared. Should it be static?

Signed-off-by: Serguey Parkhomovsky <sergueyparkhomovsky@...il.com>

v3: Wrap commit message at 72 cols, and remove filename from subject line.
v2: Don't break the build, and fix the warnings by defining the functions in libcfs.h.
