dcceafe25a [PATCH] I2O: Bugfixes
- Removed some kmalloc's with __GFP_ZERO and replace it with memset()
  because it didn't work properly.

- Fixed returned message frame in i2o_cfg_passthru() which caused raidutils
  to display wrong error message in case a disk was missing.

- Fixed size of printk() in i2o_scsi.c.

- Fixed get_device() and put_device() in probing of the I2O controller.

8129ee1642 [PATCH] s390: qdio V=V pass-through
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.

atomic64_add_unless and atomic64_inc_not_zero.  Replace old style
atomic_compare_and_swap by atomic_cmpxchg.  Shorten the whole header by

This is done by registering a special console for the mconsole driver.  This

This will capture any printk output, whether it is stack output or not, since
we can't tell the difference.

7eebe8a9c5 [PATCH] uml: umid cleanup
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.

2264c475e4 [PATCH] uml: separate libc-dependent umid code
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.

165dc59116 [PATCH] uml: Simplify console opening/closing and irq registration
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.

1f80171e81 [PATCH] uml: move console configuration
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.

418e55d49b [PATCH] uml: line_setup interface change
line_setup is changed to return the device which it set up, rather than just
success or failure.  This will be important in the line-config patch.

9010772cdf [PATCH] uml: Add static initializations and declarations
Some structure fields were being dynamically initialized when they could be
initialized at compile-time instead.  This also makes some declarations static
(in the C sense).

d571cd18f2 [PATCH] uml: Move mconsole support out of generic code
A bit of restructuring which eliminates the all_allowed argument (which is
mconsole-specific) to line_setup.  That logic is moved to the mconsole
callback.

This removes a structure field which turned out to be pointless, and

0834cc77af [PATCH] uml: use ARRAY_SIZE
This patch replaces instances of "sizeof(foo)/sizeof(foo[0])" with
ARRAY_SIZE(foo), which expands to the same thing.

d50084a299 [PATCH] uml: Formatting changes
This patch makes a bunch of non-functional changes -
    return(foo); becomes return foo;
    some statements are broken across lines for readability
    some trailing whitespace is cleaned up
    open_one_chan took four arguments, three of which could be
       deduced from the first.  Accordingly, they were eliminated.
    some examples of "} else {" had a newline added
    some whitespace cleanup in the indentation
    lines_init got some control flow cleanup
    some long lines were broken
    removed another emacs-specific C formatting comment

1b57e9c278 [PATCH] uml: non-void functions should return something
There are a few functions which are declared to return something, but don't.
These are actually infinite loops which are forced to be declared as non-void.
 This makes them all return 0.

970d6e3a34 [PATCH] uml: use kstrdup
There were a bunch of calls to uml_strdup dating from before kstrdup was
introduced.  This changes those calls.  It doesn't eliminate the definition
since there is still a couple of calls in userspace code (which should
probably call the libc strdup).
