[PATCH] kernel/fork.c is broken by the new rmap

[James Bottomley <James.Bottomley@steeleye.com>]

If your architecture makes use of flush_dcache_mm_lock() then you get
this:

kernel/fork.c: In function `dup_mmap':
kernel/fork.c:336: `mapping' undeclared (first use in this function)
kernel/fork.c:336: (Each undeclared identifier is reported only once
kernel/fork.c:336: for each function it appears in.)
