Now that we properly keep track of the CPPR value (since
49bd3647134ea47420067aea8d1401e722bf2aac, "powerpc/pseries: Track previous
CPPR values to correctly EOI interrupts") we can pass it to the
H_XIRR hcall.This is needed because the Partition Adjunct Option of new versions of
pHyp extend the H_XIRR hcall to include the CPPR as an input parameter.
Earlier versions not supporting this option just disregard the extra
input parameter, so this doesn't cause any problems for existing systems.The Partition Adjunct Option is required for future systems that will
support SR-IOV capable devices.Signed-off-by: Mark Nelson

On 64-bit kernels we currently have a 512 byte struct paca_struct for
each cpu (usually just called "the paca"). Currently they are statically
allocated, which means a kernel built for a large number of cpus will
waste a lot of space if it's booted on a machine with few cpus.We can avoid that by only allocating the number of pacas we need at
boot. However this is complicated by the fact that we need to access
the paca before we know how many cpus there are in the system.The solution is to dynamically allocate enough space for NR_CPUS pacas,
but then later in boot when we know how many cpus we have, we free any
unused pacas.Signed-off-by: Michael Ellerman

The smsgiucv_app driver registers a callback with the smsgiucv driver
to receive z/VM CP special messages (SMSG) starting with "APP".When the callback is called for special messages, the driver creates
an uevent for the received message. The uevent consists of additional
environment data containing the message prefix ("APP"), message sender,
and message content.udev rules can be used to trigger application specific actions through
matching the content or sender of the special message.Signed-off-by: Hendrik Brueckner

In z/VM it is possible to attach a device as read-only. To prevent

The device driver must allocate memory for IUCV buffers with GFP_DMA,
because IUCV cannot address memory above 2GB (31bit addresses only).Because the IUCV ignores the higher bits of the address, sending and
receiving IUCV data with this driver might cause memory corruptions.Signed-off-by: Hendrik Brueckner

Before you can read or write from the i6300esb memeory mapped registers,
you need to unlock these. This is done by writing the magic numbers 0x80
and 0x86 to the reload register. The size of the reload register is 32bit
though.Also binary 11 is hex 0x03 and not 0x11.

For now the patch_hdmi.c file is simply included by patch_intelhdmi.c
and patch_nvhdmi.c, and does not represent a real codec.There are no behavior changes to intelhdmi. However nvhdmi made several
changes when copying code out of intelhdmi, which are all reverted in
this patch. Wei Ni confirmed that the reverted code actually works fine.Tested-by: Wei Ni

Some MSI 3G netbook only have one fn key to control Wlan/Bluetooth/3G,
those netbook will load the SCM (windows app) to disable the original
Wlan/Bluetooth control by BIOS when user press fn key, then control
Wlan/Bluetooth/3G by SCM (software control by OS). Without SCM, user
cann't on/off 3G module on those 3G netbook.
On Linux, msi-laptop driver will do the same thing to disable the
original BIOS control, then might need use HAL or other userland
application to do the software control that simulate with SCM.

In the future, we are going to be changing the lock type for struct
device (once we get the lockdep infrastructure properly worked out) To
make that changeover easier, and to possibly burry the lock in a
different part of struct device, let's create some functions to lock and
unlock a device so that no out-of-core code needs to be changed in the
future.This patch creates the device_lock/unlock/trylock() functions, and
converts all in-tree users to them.Cc: Thomas Gleixner
