ppc_linux_region_ok_for_hw_watchpoint calls ppc_linux_get_hwcap, which
uses current_target,

/* Fetch the AT_HWCAP entry from the aux vector.  */
static unsigned long
ppc_linux_get_hwcap (void)
{
  CORE_ADDR field;

  if (target_auxv_search (&current_target, AT_HWCAP, &field))
    return (unsigned long) field;

  return 0;
}

Do we need to add argument 'ops' to ppc_linux_get_hwcap and stop
using current_target in ppc_linux_get_hwcap?

You may have done that in the following patches, and it is not
surprise I miss it.

Likewise, we need to add argument 'ops' to s390_get_hwcap too,
and pass ops from its caller.
