Using this patch against against 2.4.25 with evmns, libata and the
vserver patch, I get the following compilation error:-

nic@stateless:/usr/src/linux-2.4.25-vs1.3.7/mm$ gcc -D__KERNEL__ -I/usr/src/linux-2.4.25-vs1.3.7/include -Wall -Wstrict-prototypes -Wno-trigraphs -O2 -fno-strict-aliasing -fno-common -fomit-frame-pointer -pipe -mpreferred-stack-boundary=2 -march=i686   -nostdinc -iwithprefix include -DKBUILD_BASENAME=proc_mm  -c -o proc_mm.o proc_mm.c
proc_mm.c: In function `open_proc_mm':
proc_mm.c:109: error: too few arguments to function `mm_alloc'


mm_alloc seems to come from:

<linux/sched.h>
...
extern struct mm_struct * mm_alloc(struct vx_info *);


vx_info is defined in <linux/vserver/context.h>


Looks like vserver has redefined:-

-extern struct mm_struct * mm_alloc(void);
+extern struct mm_struct * mm_alloc(struct vx_info *);


I don't know the kernel well enough to add the appropiate call to:

static int open_proc_mm(struct inode *inode, struct file *file)
{
        struct mm_struct *mm = mm_alloc();

I'm guessing it might be something like 

               mm_alloc(current->vx_info);
