[PATCH] Uninline sys_mmap common code (reduce binary size)

Remove the inlining of the new vs old mmap system call common code.  This
reduces the size of the resulting vmlinux for defconfig as follows:

mb@pc1:~/develop/git/linux-2.6$ size vmlinux.mmap*
   text    data     bss     dec     hex filename
3303749  521524  186564 4011837  3d373d vmlinux.mmapinline
3303557  521524  186564 4011645  3d367d vmlinux.mmapnoinline

The new sys_mmap2() has also one function call overhead removed, now.
(probably it was already optimized to a jmp before, but anyway...)
