Lennert Buytenhek 129bd474a8 USB: ehci-orion: the Orion EHCI root hub does have a Transaction Translator
Commit 7329e211b9 ("USB: root hubs don't
lie about their number of TTs") requires the various platform EHCI
glue modules to set ->has_tt if the root hub has a Transaction
Translator.

The Orion EHCI root hub does have a Transaction Translator, so set
->has_tt in ehci_orion_setup().  This fixes oopsing on plugging in a
low speed device.

Christophe Jaillet eccf2144e1 iop-adma: fixup some kzalloc/memset confusions
1) Remove an explicit memset(.., 0, ...) to a variable allocated with
kzalloc (i.e. 'dest').

2) Allocate 'src' with kmalloc instead of kzalloc as all elements of the
'src' buffer are initialized in a 'for(...)' loop just after.

3) remove useless 'sizeof(u8)', which always returns 1, when computing the
size of the memory to be allocated.

Greg Kroah-Hartman 8882b39421 Driver core: add device_create_vargs and device_create_drvdata
We want to have the drvdata field set properly when creating the device
as sysfs callbacks can assume it is present and it can race the later
setting of this field.

So, create two new functions, deviec_create_vargs() and
device_create_drvdata() that take this new field.

device_create_drvdata() will go away in 2.6.27 as the drvdata field will
just be moved to the device_create() call as it should be.

Arjan van de Ven 81b2dbcad8 Fix a deadlock in the bttv driver
vidiocgmbuf() does this:
        mutex_lock(&fh->cap.vb_lock);
        retval = videobuf_mmap_setup(&fh->cap, gbuffers, gbufsize,
                                     V4L2_MEMORY_MMAP);

and videobuf_mmap_setup() then just does
        mutex_lock(&q->vb_lock);
        ret = __videobuf_mmap_setup(q, bcount, bsize, memory);
        mutex_unlock(&q->vb_lock);

which is an obvious double-take deadlock.

This patch fixes this by having vidiocgmbuf() just call the
__videobuf_mmap_setup function instead.

Jay Fenlason 551f4cb9de firewire: prevent userspace from accessing shut down devices
If userspace ignores the POLLERR bit from poll(), and only attempts to
read() the device when POLLIN is set, it can still make ioctl() calls on
a device that has been removed from the system.  The node_id and
generation returned by GET_INFO will be outdated, but INITIATE_BUS_RESET
would still cause a bus reset, and GET_CYCLE_TIMER will return data.
And if you guess the correct generation to use, you can send requests to
a different device on the bus, and get responses back.

This patch prevents open, ioctl, compat_ioctl, and mmap against shutdown
devices.

Diego 'Flameeyes' Petteno 6e7045990f HID: split Numlock emulation quirk from HID_QUIRK_APPLE_HAS_FN.
Since 2.6.25 the HID_QUIRK_APPLE_HAS_FN quirk is enabled even for
non-laptop Apple keyboards of the Aluminium series. The USB version of
these don't need Numlock emulation, like the laptop (and Aluminium
Wireless) do, as they have a proper keypad.

This patch splits the Numlock emulation for Apple keyboards in a
different quirk flag, so that it can be enabled for all the keyboards
but the Aluminium USB ones.

If the Numlock emulation is enabled for Aluminium USB keyboards, the
JKL and UIO keys become the numeric pad, and the rest of the keyboard
is disabled, included the key used to disable Numlock.

Additionally, these keyboard should not have a Numlock at all, as the
Numlock key is instead replaced by the 'Clear' key as usual for Apple
USB keyboards.

David S. Miller 93dae5b70e sparc64: Add global register dumping facility.
When a cpu really is stuck in the kernel, it can be often
impossible to figure out which cpu is stuck where.  The
worst case is when the stuck cpu has interrupts disabled.

Therefore, implement a global cpu state capture that uses
SMP message interrupts which are not disabled by the
normal IRQ enable/disable APIs of the kernel.

As long as we can get a sysrq 'y' to the kernel, we can
get a dump.  Even if the console interrupt cpu is wedged,
we can trigger it from userspace using /proc/sysrq-trigger

The output is made compact so that this facility is more
useful on high cpu count systems, which is where this
facility will likely find itself the most useful :)

Matthew Garrett ae6c23c4e1 Fixups to ATA ACPI hotplug
The libata-acpi.c code currently accepts hotplug messages from both the
port and the device. This does not match the behaviour of the bay
driver, and may result in confusion when two hotplug requests are
received for the same device. This patch limits the hotplug notification
to removable ACPI devices, which in turn allows it to use the _STA
method to determine whether the device has been removed or inserted.
On removal, devices are marked as detached. On insertion, a hotplug scan
is started. This should avoid lockups caused by the ata layer attempting
to scan devices which have been removed. The uevent sending is moved
outside the spinlock in order to avoid a warning generated by it firing
when interrupts are disabled.

Tejun Heo 50af2fa1e1 libata: ignore SIMG4726 config pseudo device
I was hoping ATA_HORKAGE_NODMA | ATA_HORKAGE_SKIP_PM could keep it
happy but no even this doesn't work under certain configurations and
it's not like we can do anything useful with the cofig device anyway.
Replace ATA_HORKAGE_SKIP_PM with ATA_HORKAGE_DISABLE and use it for
the config device.  This makes the device completely ignored by
libata.

Tejun Heo 906c1ff44a sata_sil24: don't use NCQ if marvell 4140 PMP is attached
When 4140 PMP is attached to sil24, NCQ commands to fan out port 1 and
2 (0 based) often stall if commands are in progress to other ports.
I've tried a number of things but can't tell what's going on.  It
never happens w/ ahci and reportedly sata_mv which can issue NCQ
commands to multiple devices simultaneously like sil24 does.

Disable NCQ for devices behind 4140 PMP for the time being.

Tejun Heo 391191c116 libata: don't schedule LPM action seperately during probing
There's no reason to schedule LPM action after probing is complete
causing another EH iteration.  Just schedule it together with probing
itself.

Tejun Heo f1bbfb90e8 libata: make sure PMP notification is turned off during recovery
PMP notification during reset can make some controllers fail reset
processing and needs to be turned off during resets.  PMP attach and
full-revalidation path did this via sata_pmp_configure() but the quick
revalidation wasn't.  Move the notification disable code right above
fan-out port recovery so that it's always turned off.

This fixes obscure reset failures.

Tejun Heo bf1bff6fa9 libata: increase PMP register access timeout to 3s
This timeout was set low because previously PMP register access was
done via polling and register access timeouts could stack up.  This is
no longer the case.  One timeout will make all following accesses fail
immediately.

In rare cases both marvell and SIMG PMPs need almost a second.  Bump
it to 3s.

While at it, rename it to SATA_PMP_RW_TIMEOUT.  It's not specific to
SCR access.
