Some BIOSes have PNP motherboard devices with resources that
partially overlap PCI BARs. The PNP system driver claims these
motherboard resources, which prevents the normal PCI driver from
requesting them later.
This patch disables the PNP resources that conflict with PCI BARs
so they won't be claimed by the PNP system driver.
Of course, this only works if PCI devices have already been enumerated.
Currently this is the case because PCI devices are discovered before
any PNP init via this path:
acpi_pci_root_init() -> acpi_pci_root_add() -> pci_acpi_scan_root() ->
pci_scan_bus_parented() -> pci_scan_child_bus() -> ...
Avuton Olrich tested this and confirmed that it fixes his ALSA sound
card (see http://lkml.org/lkml/2008/1/27/168).

RDMA connection shutdown on an SMP machine can cause a kernel crash due
to the transport close path racing with the I/O tasklet.
Additional transport references were added as follows:
- A reference when on the DTO Q to avoid having the transport
deleted while queued for I/O.
- A reference while there is a QP able to generate events.
- A reference until the DISCONNECTED event is received on the CM ID

It was all wrapped in '#ifdef CONFIG_BLOCK' anyway, so userspace was

Introduced in commit-id 9e2779fa281cfda13ac060753d674bbcaa23367e and
ifdef'ed out for nommu in 8ca3ed87db062201e1fa15b64a9214e193fc3a8a, both
approaches end up breaking the nommu build in different ways. An
impressive feat for a 2-liner.
Current is_vmalloc_addr() users fall in to two camps:
- Determining whether to use vfree()/kfree()
- Whether to do vmlist traversal (only /proc/kcore).
Since we don't support /proc/kcore on nommu, that leaves the
vfree()/kfree() determination use cases. nommu vfree() happens to be a
wrapper to kfree() anyways, so is_vmalloc_addr() can always return 0
and end up with the right behaviour.

Commit 7143740d ("IPoIB: Add send gather support") made struct
ipoib_tx_buf significantly larger, since the mapping member changed
from a single u64 to an array with MAX_SKB_FRAGS + 1 entries. This
means that allocating tx_rings with kzalloc() may fail because there
is not enough contiguous memory for the new, much bigger size. Fix
this regression by allocating the rings with vmalloc() instead.

This patch works around incorrect _PRT (PCI interrupt routing)
information from firmware. This does not fix any regressions
and can wait for the next kernel release.
On the Medion MD9580-F laptop, the BIOS says the builtin RTL8139
NIC interrupt at 00:09.0[A] is connected to \_SB.PCI0.ISA.LNKA, but
it's really connected to \_SB.PCI0.ISA.LNKB. Before this patch,
the workaround was to use "pci=routeirq". More details at
http://bugzilla.kernel.org/show_bug.cgi?id=4773.
On the Dell OptiPlex GX1, the BIOS says the PCI slot interrupt
00:0d[A] is connected to LNKB, but it's really connected to LNKA.
Before this patch, the workaround was to use "pci=routeirq".
Pierre Ossman tested a previous version of this patch and confirmed
that it fixed the problem. More details at
http://bugzilla.kernel.org/show_bug.cgi?id=5044.
On the HP t5710 thin client, the BIOS says the builtin Radeon
video interrupt at 01:00[A] is connected to LNK1, but it's really
connected to LNK3. The previous workaround was to use a custom
DSDT. I tested this patch and verified that it fixes the problem.

There is a problem in the hibernation code that triggers on some NUMA
systems on which pfn_valid() returns 'true' for some PFNs that don't
belong to any zone. Namely, there is a BUG_ON() in
memory_bm_find_bit() that triggers for PFNs not belonging to any
zone and passing the pfn_valid() test. On the affected systems it
triggers when we mark PFNs reported by the platform as not saveable,
because the PFNs in question belong to a region mapped directly using
iorepam() (i.e. the ACPI data area) and they pass the pfn_valid()
test.
Modify memory_bm_find_bit() so that it returns an error if given PFN
doesn't belong to any zone instead of crashing the kernel and ignore
the result returned by it in mark_nosave_pages(), while marking the
"nosave" memory regions.
This doesn't affect the hibernation functionality, as we won't touch
the PFNs in question anyway.

Commit 7143740d ("IPoIB: Add send gather support") made it possible
for tx_wr.num_sge to be != 1 -- this happens if send gather support is
enabled. However, the code in the connected mode post_send() function
assumes the old invariant, namely that tx_wr.num_sge is always 1. Fix
this by explicitly setting tx_wr.num_sge to 1 in the CM post_send().

With TSO it was possible to send past the receiver window when the skb
to be sent was the last in the write queue while the receiver window
is the limiting factor. One can notice that there's a loophole in the
tcp_mss_split_point that lacked a receiver window check for the
tcp_write_queue_tail() if also cwnd was smaller than the full skb.
Noticed by Thomas Gleixner <tglx@linutronix.de> in form of "Treason
uncloaked! Peer ... shrinks window .... Repaired." messages (the peer
didn't actually shrink its window as the message suggests, we had just
sent something past it without a permission to do so).

Acer violate the ACPI-WMI spec by declaring some of their data blocks as
expensive, but with no corresponding WCxx method. There is already some
workaround code in to handle the initial WCxx call (we just ignore a
failure here); but we need to properly check if the second, "clean up",
WCxx call is actually needed or not, rather than fail simply because it
isn't there.

When set_multicast_list() is called the multicast task is restarted
and the IPOIB_MCAST_STARTED bit is cleared. As a result for some
window of time, multicast packets are not transmitted nor queued but
rather dropped by ipoib_mcast_send(). These dropped packets are
painful in two cases:
- bonding fail-over which both calls set_multicast_list() on the new
active slave and sends Gratuitous ARP through that slave.
- IP_DROP_MEMBERSHIP code which both calls set_multicast_list() on the
device and issues IGMP leave.
In both these cases, depending on the scheduling of the IPoIB
multicast task, the packets would be dropped. As a result, in the
bonding case, the failover would not be detected by the peers until
their neighbour is renewed the neighbour (which takes a few tens of
seconds). In the IGMP case, the IP router doesn't get an IGMP leave
and would only learn on that from further probes on the group (also a
delay of at least a few tens of seconds).
Fix this by allowing transmission (or queuing) depending on the
IPOIB_FLAG_OPER_UP flag instead of the IPOIB_MCAST_STARTED flag.

This patch fixes the initialization of RC QPs, since we would rely on
the queue pair type (ibqp->qp_type) being set, but this field is only
initialized when we return from ipath_create_qp (it is initialized by

The fix is to not depend on this field to initialize the send and
the receive state of the RC QP.

There can be a case where the requester's rnr retry counter
(s_rnr_retry) is less than the number of rnr retries allowed per QP
(s_rnr_retry_cnt). This can happen if the s_rnr_retry counter is being
decremented and an ipath_query_qp call is issued during that time frame.
The fix is to always return the number of rnr retries allowed per QP
instead of the requester's rnr counter.
