[IA64] Provide ACPI fixup for /proc/cpuinfo/physical_id
Legacy HP ia64 platforms currently cannot provide
/proc/cpuinfo/physical_id due to legacy SAL/PAL implementations.
However, that physical topology information can be obtained
via ACPI.
Provide an interface that gives ACPI one last chance to provide
physical_id for these legacy platforms. This logic only comes
into play iff:
- ACPI actually provides slot information for the CPU
- we lack a valid socket_id
Otherwise, we don't do anything.
Since x86 uses the ACPI processor driver as well, we provide a nop

V4L/DVB (7769): Move other terrestrial tuners to common/tuners
Those tuners are currently used only under media/dvb. However,
they can support also analog TV. Better to move them to the same place
as the other hybrid tuners. This would make easier to use those tuners also
by analog drivers.
There were several issues in the past, caused by the hybrid tuner design, since
now, the same tuner can be used by drivers/media/dvb and drivers/media/video.
Kconfig items were rearranged, to split V4L/DVB core from their drivers.
Tuner setup were happening during i2c attach callback. This means that it would
happen on two conditions:
1) if tuner module weren't load, it will happen at request_module("tuner");
2) if tuner is not compiled as a module, or it is already loaded
(for example, on setups with more than one tuner), it will happen
when saa7134 registers I2C bus.
Due to that, if tuner were loaded, tuner setup will happen _before_ reading
the proper values at tuner eeprom. Since set_addr refuses to change for a tuner
that were previously defined (except if the tuner_addr is set), this were
making eeprom tuner detection useless.
This patch removes tuner type setup from saa7134-i2c, moving it to the proper
place, after taking eeprom into account.

Commit cb9fbc5c ("IB: expand ib_umem_get() prototype") changed the
mthca userspace ABI to provide a way for userspace to indicate which

possible to handle this without breaking existing userspace, by having
the mthca kernel driver recognize whether it is talking to old or new
userspace, depending on the size of the register MR structure passed in.
The only potential drawback of this is that is allows old userspace
(which has a bug with DMA ordering on large SGI Altix systems) to
continue to run on new kernels, but the advantage of allowing old
userspace to continue to work on unaffected systems seems to outweigh
this, and we can print a warning to push people to upgrade their
userspace.

RDMA/cxgb3: Support peer-2-peer connection setup
Open MPI, Intel MPI and other applications don't respect the iWARP
requirement that the client (active) side of the connection send the
first RDMA message. This class of application connection setup is
called peer-to-peer. Typically once the connection is setup, _both_
sides want to send data.
This patch enables supporting peer-to-peer over the chelsio RNIC by
enforcing this iWARP requirement in the driver itself as part of RDMA
connection setup.
Connection setup is extended, when the peer2peer module option is 1,
such that the MPA initiator will send a 0B Read (the RTR) just after
connection setup. The MPA responder will suspend SQ processing until
the RTR message is received and reply-to.
In the longer term, this will be handled in a standardized way by
enhancing the MPA negotiation so peers can indicate whether they
want/need the RTR and what type of RTR (0B read, 0B write, or 0B send)
should be sent. This will be done by standardizing a few bits of the
private data in order to negotiate all this. However this patch
enables peer-to-peer applications now and allows most of the required
firmware and driver changes to be done and tested now.
Design:
- Add a module option, peer2peer, to enable this mode.
- New firmware support for peer-to-peer mode:
- a new bit in the rdma_init WR to tell it to do peer-2-peer
and what form of RTR message to send or expect.
- process _all_ preposted recvs before moving the connection
into rdma mode.
- passive side: defer completing the rdma_init WR until all
pre-posted recvs are processed. Suspend SQ processing until
the RTR is received.
- active side: expect and process the 0B read WR on offload TX
queue. Defer completing the rdma_init WR until all
pre-posted recvs are processed. Suspend SQ processing until
the 0B read WR is processed from the offload TX queue.
- If peer2peer is set, driver posts 0B read request on offload TX
queue just after posting the rdma_init WR to the offload TX queue.
- Add CQ poll logic to ignore unsolicitied read responses.

The new queue_flag_set/clear() functions verify that the queue is
locked, but in doing so they will actually instead oops if the queue
lock hasn't been initialized at all.
So fix the lock debug test to consider the "no lock" case to be
unlocked. This way you get a nice WARN_ON_ONCE() instead of a fatal
oops.

Causes the kexec of a RHEL 5.1 kernel to fail.
root casue: the rhel 5.1 kernel still uses INTx emulation. and
mptscsih_shutdown doesn't call pci_disable_msi to reenable INTx on kexec path
So call pci_msi_shutdown in the shutdown path to do the same thing to msix

For MSI, default_shutdown will call mask_bit for msi device. All mask bits
will left disabled after free_irq. Then in the kexec case, the next kernel
can only use msi_enable bit, so all device's MSI can not be used.
So lets to restore the mask bit to its pci reset defined value (enabled) when
we disable the kernels use of msi to be a little friendlier to kexec'd kernels.
Extend msi_set_mask_bit to msi_set_mask_bits to take mask, so we can fully
restore that to 0x00 instead of 0xfe.
