* Notes:
* - PLT stub handling
* On 32bit (and sometimes 64bit) and with big kernel modules like xfs or
* ipv6 the relocation types R_PARISC_PCREL17F and R_PARISC_PCREL22F may
* fail to reach their PLT stub if we only create one big stub array for
* all sections at the beginning of the core or init section.
* Instead we now insert individual PLT stub entries directly in front of
* of the code sections where the stubs are actually called.
* This reduces the distance between the PCREL location and the stub entry
* so that the relocations can be fulfilled.
* While calculating the final layout of the kernel module in memory, the
* kernel module loader calls arch_mod_section_prepend() to request the
* to be reserved amount of memory in front of each individual section.
*
* - SEGREL32 handling
* We are not doing SEGREL32 handling correctly. According to the ABI, we
* should do a value offset, like this:

* We need to store a record of which parts of the origin have
* been copied to the snapshot device. The snapshot code
* requires that we copy exception chunks to chunk aligned areas
* of the COW store. It makes sense therefore, to store the
* metadata in chunk size blocks.
*
* There is no backward or forward compatibility implemented,
* snapshots with different disk versions than the kernel will
* not be usable. It is expected that "lvcreate" will blank out
* the start of a fresh COW device before calling the snapshot
* constructor.
*
* The first chunk of the COW device just contains the header.
* After this there is a chunk filled with exception metadata,
* followed by as many exception chunks as can fit in the
* metadata areas.
*
* All on disk structures are in little-endian format. The end
* of the exceptions info is indicated by an exception with a
* new_chunk of 0, which is invalid since it would point to the
