New feature V=V qdio pass-through.
QDIO and HiperSockets processing in z/VM V=V guest environments (as well as
V=R with z/VM running in LPAR mode) requires shadowing of all QDIO
architecture queue elements. Especially the shadowing of SBALs and SLSBs
structures in the hypervisor, and the need to issue SIGA SYNC operations to
observe state changes, eventually causes significant CPU processing overhead
in the hypervisor.
The QDIO pass-through support for V=V guests avoids the shadowing of SBALs and
SLSBs. This significantly reduces the hypervisor overhead for QDIO based I/O.

Fix the broken atomic_cmpxchg primitive. Add atomic_sub_and_test,
atomic64_sub_return, atomic64_sub_and_test, atomic64_cmpxchg,
atomic64_add_unless and atomic64_inc_not_zero. Replace old style
atomic_compare_and_swap by atomic_cmpxchg. Shorten the whole header by
defining most primitives with the two inline functions atomic_add_return and
atomic_sub_return.
In addition this patch contains the s390 related fixes of Hugh's "mm: fill

The stack command now sends the printk output back to the mconsole client.
This is done by registering a special console for the mconsole driver. This
receives all printk output. Normally, it is ignored, but when a stack command
is issued, any printk output will be sent back to the client.
This will capture any printk output, whether it is stack output or not, since
we can't tell the difference.

This is needed for the console output patch, since we have a possibly
non-NULL-terminated string there. So, the new interface takes a string and a
length, and the old interface calls strlen on its string and calls the new
interface with the length.

This patch cleans up the umid code:
- The only_if_set argument to get_umid is gone.
- get_umid returns an empty string rather than NULL if there is no umid.
- umid_is_random is gone since its users went away.
- Some printfs were turned into printks because the code runs late enough
that printk is working.
- Error paths were cleaned up.
- Some functions now return an error and let the caller print the error
message rather than printing it themselves. This eliminates the practice of
passing a pointer to printf or printk in, depending on where in the boot
process we are.
- Major tidying of not_dead_yet - mostly error path cleanup, plus a comment
explaining why it doesn't react to errors the way you might expect.
- Calls to os_* interfaces that were moved under os are changed back to
their native libc forms.
- snprintf, strlcpy, and their bounds-checking friends are used more often,
replacing by-hand bounds checking in some places.

I reworked Gennady's umid OS abstraction patch because the code shouldn't
be moved entirely to os. As it turns out, I moved most of it anyway. This
patch is the minimal one needed to move the code and have it work.
It turns out that the concept of the umid is OS-independent, but
almost everything else about the implementation is OS-dependent.
This is code movement without cleanup - a follow-on patch tidies
everything up without shuffling code around.

This patch simplifies the opening and closing of host console devices and the
registration and deregistration of IRQs. The intent is to make it obvious
that an IRQ can't exist without an open file descriptor.
chan_enable will now open the channel, and when both opening and IRQ
registration are desired, this should be used. Opening only is done for the
initial console, so that interface still needs to exist.
The free_irqs_later interface is now gone. It was intended to avoid freeing
an IRQ while it was being processed. It did this, but it didn't eliminate the
possiblity of free_irq being called from an interrupt, which is bad. In its
place is a list of irqs to be freed, which is processed by the signal handler
just before exiting. close_one_chan now disables irqs.
When a host device disappears, it is just closed, and that disables IRQs.
The device id registered with the IRQ is now the chan structure, not the tty.
This is because the interrupt arrives on a descriptor associated with the
channel. This caused equivalent changes in the arguments to line_timer_cb.
line_disable is gone since it is not used any more.
The count field in the line structure is gone. tty->count is used instead.
The complicated logic in sigio_handler with freeing IRQs when necessary and
making sure its idea of the next irq is correct is now much simpler. The irq
list can't be rearranged underneath it, so it is now a simple list walk.

This patch changes when console devices are configured in order to prepare the
ground for the next patch.
parse_chan_pair is now done earlier, when initcalls are run, rather than when
the device is opened.
When a host device disappears, the channel list is closed, but not freed.
This is required by the previous change. line_config now takes the options
structure as an argument, and line_open doesn't.

o Currently, during kexec reboot, IOAPIC is re-programmed back to virtual
wire mode if there was an i8259 connected to it. This enables getting
timer interrupts in second kernel in legacy mode.
o After putting into virtual wire mode, IOAPIC delivers the i8259 interrupts
to CPU0. This works well for kexec but not for kdump as we might crash
on a different CPU and second kernel will not see timer interrupts.
o This patch modifies the redirection table entry to deliver the timer
interrupts to the cpu we are rebooting (instead of hardcoding to zero).
This ensures that second kernel receives timer interrupts even on a
non-boot cpu.

The 'make rodata read-only' patch in -mm exposes a latent bug in the 32-bit
change_page_attr() function, which causes certain CPUs (Those with NX
basically) to reboot instantly after pages are marked read-only.
The same bug got fixed a while back on x86-64, but never got propagated to
i386.
Stuart Hayes from Dell also picked up on this last June, but it never got
fixed, as the only thing affected by it aparently was the nvidia driver.
Blatantly stealing description from his post..
"It doesn't appear to be fixed (in the i386 arch). The
change_page_attr()/split_large_page() code will still still set all the
4K PTEs to PAGE_KERNEL (setting the _PAGE_NX bit) when a large page
needs to be split.
This wouldn't be a problem for the bulk of the kernel memory, but there
are pages in the lower 4MB of memory that's free, and are part of large
executable pages that also contain kernel code. If change_page_attr()
is called on these, it will set the _PAGE_NX bit on the whole 2MB region
that was covered by the large page, causing a large chunk of kernel code
to be non-executable."
