I've been hunting down a bug affecting IBM x440/x445 systems where the
floppy driver would get spurious interrupts and would not initialize
properly.

After digging James Cleverdon and Bill Irwin pointed out that target_cpus()
is routing the interrupts to the clustered apic broadcast mask using
destFixed deliver mode.  This was causing multiple interrupts to show up,
breaking the floppy init code.

This fix simply changes the delivery mode to dest_LowestPrio and initially
routes interrupts to the first cpu to resolve this issue.

An attempt to fix the random poking in legacy io space...

ask for permissions before poking at io ports.  this affects
detect_and_report_winbond() and detect_and_report_smsc().

Its unclear what port number is returned in show_parconfig_winbond(), so
just request the region as well and free the probing region.

sound/core/pcm_native.c was assuming that all architectures implement
io_remap_page_range() in the same way.  They don't, so the sparc64 build
broke.

mmap callback is added to PCM ops.  The driver can implement its own mmap
method.

Also, mmapping of the status and control records is available only on known
coherent architectures now.

Dmitry Torokhov triggered a problem in the new pidhash macros: These
do_each_task_pid()/while_each_task_pid() do loop forever if you use a
'continue' inside them. 

The end of the loop has to be inside the "while()" statement, so as to
not make "continue" jump over it.

There is a possible deadlock condition with conntrack/nat-helpers:

CPU1:
conntrack-helper:help: lock(private_lock)
ip_conntrack_expect_related: write_lock(ip_conntrack_lock)

CPU2:
nat-core:do_bindings: read_lock(ip_conntrack_lock)
nat-helper:help: lock(private_lock)

The lock in the nat-helper is unneccessary because the expectation
is never changed and is protected by ip_conntrack_lock.

This patch fixes strange and obscure pid implementation in current kernels:
- it removes calling of put_task_struct() from detach_pid()
  under tasklist_lock. This allows to use blocking calls
  in security_task_free() hooks (in __put_task_struct()).
- it saves some space = 5*5 ints = 100 bytes in task_struct
- it's smaller and tidy, more straigthforward and doesn't use
  any knowledge about pids using and assignment.
- it removes pid_links and pid_struct doesn't hold reference counters
  on task_struct. instead, new pid_structs and linked altogether and
  only one of them is inserted in hash_list.
