Stop abusing ide_lock lock (switch to a private locking).
Fixes same issue as fixed by Alan Cox in atiixp host driver with
commit 6c5f8cc33e.
ht6560b is a bit special cause we still need to leave ide_lock for
->set_pio_mode with 'pio' argument == 8/9 (prefetch disable/enable).

Prior to use struct marker in the linux kernel markers, we need to clean
two drivers which use this structure name.
Change bonding driver types :
- struct marker to struct bond_marker.
- marker_t to bond_marker_t.
- marker_header to bond_marker_header.
- marker_header_t to bond_marker_header_t.
Change qla4xxx struct marker_entry usage :
- Change struct marker_entry for struct qla4_marker_entry.

The task_struct->pid member is going to be deprecated, so start
using the helpers (task_pid_nr/task_pid_vnr/task_pid_nr_ns) in
the kernel.
The first thing to start with is the pid, printed to dmesg - in
this case we may safely use task_pid_nr(). Besides, printks produce
more (much more) than a half of all the explicit pid usage.
