PROBLEM: The module loop.o has an unresolved dependency: deactivate_page()

PROBLEM: The module loop.o has an unresolved dependency: deactivate_page()

[Roby]

Kernel 2.4.14

[1.] The module loop.o has an unresolved dependency: deactivate_page()
[2.] If I compile the module loop.o as a module it compiles fine,but then it 
has un unresolved dependency: deactivate_page(). This function once was in 
the source file mm/swap.c, but in the kernel 2.4.14 it disappeared. I know 
the function existed in the kernel 2.4.10.

[8.] The function deactivate_page() is not defined elsewhere. What have I to 
do for having the loop block device?
