Firmware changed the way it represents memory and cpu affinity on POWER7.
Unfortunately the old method now caps the topology to work around issues
with legacy operating systems. For Linux to get the correct topology we
need to use the new form 1 affinity information.
We set the form 1 field in the client architecture, and if we see "1" in the
ibm,associativity-form property firmware supports form 1 affinity and
we should look at the first field in the ibm,associativity-reference-points
array. If not we use the second field as we always have.

Re-submitted based on comments from netdev community.
Summary of the changes:
1. Improved error handling.
2. Added the missing timeout arguments to usb_control_msg().
The following is a new Linux driver which exposes certain models of Sierra
Wireless modems to the operating system as Network Interface Cards (NICs).
This driver requires a version of the sierra.c driver which supports
blacklisting to work properly. The blacklist in sierra.c rejects the interfaces
claimed by sierra_net.c. Likewise, the sierra_net.c driver only accepts
(i.e. whitelists) the interface(s) used for USB-to-WWAN traffic.
The version of sierra.c which supports blacklisting is
available from the sierra wireless knowledge base page for older kernels. It is
also available in Linux kernel starting from version 2.6.31.
This driver works with all Sierra Wireless devices configured with PID=68A3
like USB305, USB306 provided the corresponding firmware version is I2.0
(for USB305) or M3.0 (for USB306) and later.
This driver will not work with earlier firmware versions than the ones shown
above. In this case the driver will issue an error message indicating
incompatibility and will not serve the device's USB-to-WWAN interface.
Sierra_net.c sits atop a pre-existing Linux driver called usbnet.c.
A series of hook functions are provided in sierra_net.c which are called by
usbnet.c in response to a particular condition such as receipt or transmission
of a data packet. As such, usbnet.c does most of the work of making
a modem appear to the system as a network device and for properly exchanging
traffic between the USB subsystem and the Network card interface.
Sierra_net.c is concerned with managing the data exchanged between the
USB-to-WWAN interface and the upper layers of the operating system.

The request_key() system call and request_key_and_link() should make a
link from an existing key to the destination keyring (if supplied), not
just from a new key to the destination keyring.
This can be tested by:
ring=`keyctl newring fred @s`
keyctl request2 user debug:a a
keyctl request user debug:a $ring
keyctl list $ring
If it says:
keyring is empty
then it didn't work. If it shows something like:
1 key in keyring:
1070462727: --alswrv 0 0 user: debug:a
then it did.
request_key() system call is meant to recursively search all your keyrings for
the key you desire, and, optionally, if it doesn't exist, call out to userspace
to create one for you.
If request_key() finds or creates a key, it should, optionally, create a link
to that key from the destination keyring specified.
Therefore, if, after a successful call to request_key() with a desination
keyring specified, you see the destination keyring empty, the code didn't work
correctly.
If you see the found key in the keyring, then it did - which is what the patch
is required for.

Bill Gatliff reported the following bug when using the irq_chip facility
of the pca953x driver on a PPC platform:
BUG: scheduling while atomic: insmod/1530/0x00000002
He traced it back to an i2c transaction in pca953x_irq_set_type(), which
can be called with interrupt disabled (from __setup_irq()). As the i2c
controller can sleep while sending a message, this qualifies as a bad
idea.
This patch moves the i2c transaction to pca953x_irq_bus_sync_unlock(),
where it is actually safe to send an i2c message.

keyring_read() doesn't need to use rcu_dereference() to access the keyring
payload as the caller holds the key semaphore to prevent modifications
from happening whilst the data is read out.

The bonding driver calls ndo_vlan_rx_register() while holding bond->lock.
The bnx2 driver calls bnx2_netif_stop() to stop the rx handling while
changing the vlgrp. The call also stops the cnic driver which sleeps
while the bond->lock is held and cause the warning.
This code path only needs to stop the NAPI rx handling while we are
changing the vlgrp. Since no reset is going to occur, there is no need
to stop cnic in this case. By adding a parameter to bnx2_netif_stop()
to skip stopping cnic, we can avoid the warning.

It has been reported that under certain heavy traffic conditions in MSI-X
mode, the driver can lose an MSI-X vector causing all packets in the
associated rx/tx ring pair to be dropped. The problem is caused by
the chip dropping the write to unmask the MSI-X vector by the kernel
(when migrating the IRQ for example).
This can be prevented by increasing the GRC timeout value for these
register read and write operations.
Thanks to Dell for helping us debug this problem.

Prompted by a previous patch submitted by Matthew Garret <mjg@redhat.com>,
further digging into errata documentation reveals the current enabling or
disabling of ASPM L0s and L1 states for certain parts supported by this
driver are incorrect. 82571 and 82572 should always disable L1. For
standard frames, 82573/82574/82583 can enable L1 but L0s must be disabled,
and for jumbo frames 82573/82574 must disable L1. This allows for some
parts to enable L1 in certain configurations leading to better power
savings.
Also according to the same errata, Early Receive (ERT) should be disabled
on 82573 when using jumbo frames.

powerpc: Make the 64-bit kernel as a position-independent executable
The change to __va and __pa to use PAGE_OFFSET & MEMORY_START causes
problems on the Book-E parts because we don't know MEMORY_START until
after we parse the device tree. We need __va to work properly to even
parse the device tree so we have a chicken an egg. So go back to using
he other definition of __va/__pa on CONFIG_BOOKE and use the
PAGE_OFFSET/MEMORY_START version on "Classic" PPC64.
Also updated casts to handle phys_addr_t being a different size from
unsigned long (ie 36-bit physical on PPC32).

When read_buf is called to move over to the next page in the pagelist
of an NFSv4 request, it sets argp->end to essentially a random
number, certainly not an address within the page which argp->p now
points to. So subsequent calls to READ_BUF will think there is much
more than a page of spare space (the cast to u32 ensures an unsigned
comparison) so we can expect to fall off the end of the second
page.
We never encountered thsi in testing because typically the only
operations which use more than two pages are write-like operations,
which have their own decoding logic. Something like a getattr after a
write may cross a page boundary, but it would be very unusual for it to
cross another boundary after that.

Fix perf probe to use symtab only if there is no debuginfo, because debuginfo
has more information than symtab.
If we can't find a function in debuginfo, we never find it in symtab.

If dso->node member is not initialized, it causes a segmentation fault when
adding to other lists.
It should be initilized in dso__new().
