Subject: [PATCH -next] block: genhd errors when CONFIG_PROC_FS=n

From: Randy Dunlap <randy.dunlap@...cle.com>

block/genhd.c has build errors when CONFIG_PROC_FS=n, so omit some of
its functions in that case.

/local/linsrc/linux-next-20080523/block/genhd.c: In function 'diskstats_start':
/local/linsrc/linux-next-20080523/block/genhd.c:555: error: 'find_start' undeclared (first use in this function)
/local/linsrc/linux-next-20080523/block/genhd.c:555: error: (Each undeclared identifier is reported only once
/local/linsrc/linux-next-20080523/block/genhd.c:555: error: for each function it appears in.)
make[2]: *** [block/genhd.o] Error 1
