If these flags are set when the QP is transitioned to the error state,
it will wait until the flags are cleared, which may never happen if
the error transition is due to a link going down.

The driver was incorrectly choosing HCAs on which to allocate new user

When the link transitions from ACTIVE_DEFERRED to ACTIVE, the driver
only sees the ACTIVE state. With this change, it will check whether
the state was already ACTIVE and if so, it will not generated IB
events and will not clear symbol error counts.

The code to generate receive completion entries for UD send with
immediate contains the wrong payload length. This is because when the
code to compute the payload size was moved, the value of hdrsize
didn't get moved too. The fix is to update tlen directly.

The IBTA vol. 1 release 1.2.1 spec. says:
C14-24.2.1: If PortInfo:Portstate=Down, then a SubnSet(PortInfo) shall
make any changes it specifies to PortInfo:PortPhysicalState; any other
result is vendor-dependent.
The patch changes the error handling so that the reply says there are
invalid fields but still attempts to set fields that are in range
including PortInfo:PortPhysicalState.

mlx4_ib_free_cq_buf() should not be called under spin_lock_irq() since
it calls dma_free_coherent(), which needs irqs enabled. Fix this by

The kernel warning message added in commit 58d74bb1d9f7 ("mlx4_core:
Workaround firmware bug in query dev cap") about mlx4 reporting the
wrong number of "blue flame registers" doesn't really help anyone, since
the firmware bug is known and fixed and the bug is pretty much harmless
to users. So just get rid of the warning.

As a first step in moving from LRO to GRO, revert commit af40da894e9
("IPoIB: add LRO support"). Also eliminate the ethtool set_flags
callback which isn't needed anymore. Finally, we need to include
<linux/sched.h> directly to get the declaration of restart_syscall()
(which used to be included implicitly through <linux/inet_lro.h>).

Re-initializing the wait object in rdma_init()/rdma_fini() causes a
timing window which can lead to a deadlock during close. Once this
deadlock hits, all RDMA activity over the T4 device will be stuck.
There's no need to re-init the wait object, so remove it.

mmaps[map_idx] = NULL;
}
page_offset = page_size * (head / page_size);

IPv4 over firewire needs to be able to remove ARP entries
from the ARP cache that belong to nodes that are removed, because
IPv4 over firewire uses ARP packets for private information
about nodes.
This information becomes invalid as soon as node drops
off the bus and when it reconnects, its only possible
to start talking to it after it responded to an ARP packet.
But ARP cache prevents such packets from being sent.

HTB takes into account skb is segmented in stats updates.
Generalize this to all schedulers.

And a test for it:
[acme@felicio linux]$ perf test
1: vmlinux symtab matches kallsyms: Ok
2: detect open syscall event: Ok
3: detect open syscall event on all cpus: Ok
[acme@felicio linux]$
Translating C the test does:
1. generates different number of open syscalls on each CPU
by using sched_setaffinity
2. Verifies that the expected number of events is generated
on each CPU
It works as expected.

Update the CS4270 driver to use ASoC's internal codec register cache feature.
This change allows ASoC to perform the low-level I2C operations necessary to
read the register cache. Support is also added for initializing the register
cache with an array of known power-on default values.
The CS4270 driver was handling the register cache itself, but somwhere along
the conversion to multi-compaonent, this feature broke.

For the VFs, the Mailbox Data "registers" are actually backed by
T4's "MA" interface rather than PL Registers (as is the case for
the PFs). Because these are in different coherency domains, the
write to the VF's PL-register-backed Mailbox Control can race in
front of the writes to the MA-backed VF Mailbox Data "registers".
So we need to do a read-back on at least one byte of the VF Mailbox
Data registers before doing the write to the VF Mailbox Control
register.

Driver is reading flash fw version from defined address, this address
may be invalid. Indeed Driver should read address for fw version through
flash layout table. Flash layout table has defined region and address for
fw version address should be read from fw image region.
Driver has check for old firmware, this bug can cause driver load fail.
This patch will try to read fw version from flash image region, if that fails,

Dan Rosenberg pointed out that there were some signed comparison bugs
in the phonet protocol.
http://marc.info/?l=full-disclosure&m=129424528425330&w=2
The problem is that we check for array overflows but "protocol" is
signed and we don't check for array underflows. If you have already
have CAP_SYS_ADMIN then you could use the bugs to get root, or someone
could cause an oops by mistake.
