v5.15-dovetail-rebase compilation fails

[G.Strobbe via Xenomai]

Hi all,

The compilation of file xenomai/kernel/cobalt/debug.c 
in branch v5.15-dovetail-rebase failed.
The problem is that since kernel vanilla v15.5 
include/linux/mm.h no longer defines VM_DENYWRITE

It is still used in xndebug_trace_relax()

                /*
                 * Hack. Unlike DSOs, executables and interpreters
                 * (e.g. dynamic linkers) are protected against write
                 * attempts. Use this to determine when $pc should be
                 * fixed up by subtracting the mapping base address in
                 * the DSO case.
                 */
                if (!(vma->vm_flags & VM_DENYWRITE))
                        pc -= vma->vm_start;

Best regards,

Gino
