Fixed an error unwind in bonding_store_bonds that didn't release
the locks it held, and consolidated unwinds into a common block at the
end of the function. Bug reported by Pavel Emelyanov <xemul@openvz.org>,
who provided a different fix.

If the call to bond_create_sysfs_entry in bond_create fails, the
proper rollback is to call unregister_netdevice, not free_netdev.
Otherwise - kernel BUG at net/core/dev.c:4057!
Checked with artificial failures injected into bond_create_sysfs_entry.
Pavel's original patch modified by Jay Vosburgh to move code around
for clarity (remove goto-hopping within the unwind block).

As noticed by Ben Greear, macvlan crashes the kernel when unloading the
module. The reason is that it tries to clean up the macvlan_port pointer
on the macvlan device itself instead of the underlying device. A non-NULL
pointer is taken as indication that the macvlan_handle_frame_hook is
valid, when receiving the next packet on the underlying device it tries
to call the NULL hook and crashes.
Clean up the macvlan_port on the correct device to fix this.

Fix allmodconfig build bug introduced in latest -git by commit
7c91f0624a9 ("V4L/DVB(7767): Move tuners to common/tuners"):
LD kernel/built-in.o
LD drivers/built-in.o
ld: drivers/media/built-in.o: No such file: No such file or directory
which happens if all media drivers are modular:
http://redhat.com/~mingo/misc/config-Wed_Apr_30_09_24_48_CEST_2008.bad
In that case there's no obj-y rule connecting all the built-in.o files and
the link tree breaks.
The fix is to add a guaranteed obj-y rule for the core vmlinux to build.
(which results in an empty object file if all media drivers are modular)

What's fixed:
in ipath_cancel_sends()
We need to unconditionally set ABORTING. So, swap the tests
so the set_bit() isn't shadowed by the &&.
If we've disarmed the piobufs, then we need to unconditionally
set DISARMED. So, move it out from the overly protective if
at the bottom.
in sdma_abort_task()
Abort_task was written knowing that the SDMA engine would always
be reset (and restarted) on error. A recent change broke that
fundamental assumption by taking the restart portion and making
it conditional on a link status change. But, SDMA can go boom
without a link status change in some conditions.

Now that we always use PIO for vl15 on 7220, we could get stuck forever
if we happened to run out of PIO buffers from the verbs code, because
the setup code wouldn't run; the interrupt was also ignored if SDMA was
supported. We also have to reduce the pio update threshold if we have
fewer kernel buffers than the existing threshold.
Clean up the initialization a bit to get ordering safer and more
sensible, and use the existing ipath_chg_kernavail call to do init,
rather than doing it separately.
Drop unnecessary clearing of pio buffer on pio parity error.
Drop incorrect updating of pioavailshadow when exitting freeze mode
(software state may not match chip state if buffer has been allocated
and not yet written).
If we couldn't get a kernel buffer for a while, make sure we are
in sync with hardware, mainly to handle the exitting freeze case.

The loop in ipath_kreceive() that processes packets increments the
loop-index 'i' once too often, because the exit condition does not
depend on it, and is checked after the increment. By adding a check for
!last to the iterator in the for loop, we correct that in a way that is
not so likely to be re-broken by changes in the loop body.

Currently, iw_cxgb3 is severely limited on the amount of userspace
memory that can be registered in in a single memory region, which
causes big problems for applications that expect to be able to
register 100s of MB.
The problem is that the driver uses a single kmalloc()ed buffer to
hold the physical buffer list (PBL) for the entire memory region
during registration, which means that 8 bytes of contiguous memory are
required for each page of memory being registered. For example, a 64
MB registration will require 128 KB of contiguous memory with 4 KB
pages, and it unlikely that such an allocation will succeed on a busy
system.
This is purely a driver problem: the temporary page list buffer is not
needed by the hardware, so we can fix this by writing the PBL to the
hardware in page-sized chunks rather than all at once. We do this by
splitting the memory registration operation up into several steps:
- Allocate PBL space in adapter memory for the full registration
- Copy PBL to adapter memory in chunks
- Allocate STag and enable memory region
This also allows several other cleanups to the __cxio_tpt_op()
interface and related parts of the driver.
This change leaves the reregister memory region and memory window
operations broken, but they already didn't work due to other
longstanding bugs, so fixing them will be left to a later patch.

Current iw_cxgb3 code adds PBL memory to the driver's gen_pool in 2 MB
chunks. This limits the largest single allocation that can be done to
the same size, which means that with 4 KB pages, each of which takes 8
bytes of PBL memory, the largest memory region that can be allocated
is 1 GB (256K PBL entries * 4 KB/entry).
Remove this limit by adding all the PBL memory in a single gen_pool
chunk, if possible. Add code that falls back to smaller chunks if
gen_pool_add() fails, which can happen if there is not sufficient
contiguous lowmem for the internal gen_pool bitmap.

get_part() is fairly expensive, as it O(N) loops over partitions
to find the right one. In lots of normal IO paths we end up looking
up the partition twice, to make matters even worse. Change the
stat add code to accept a passed in partition instead.

The file drivers/usb/serial/iuu_phoenix.c uses "int" for flags. This can
cause hard to find bugs on some architectures. This patch converts the flags
to use "long" instead.
This bug was discovered by doing an allyesconfig make on the -rt kernel where
checks are done to ensure all flags are of size sizeof(long).

A couple of distributions (Fedora, Ubuntu) were having weird problems with the
ATI IXP series PATA controllers being reported as simplex. At the heart of
the problem is that both distros ignored the recommendations to load pata_acpi
and ata_generic *AFTER* specific host drivers.
The underlying cause however is that if you D3 and then D0 an ATI IXP it
helpfully throws away some configuration and won't let you rewrite it.
Add checks to ata_generic and pata_acpi to pin ATIIXP devices. Possibly the
real answer here is to quirk them and pin them, but right now we can't do that
before they've been pcim_enable()'d by a driver.
I'm indebted to David Gero for this. His bug report not only reported the
problem but identified the cause correctly and he had tested the right values
to prove what was going on
[If you backport this for 2.6.24 you will need to pull in the 2.6.25
removal of the bogus WARN_ON() in pcim_enagle]

sata_inic162x now doesn't use any SFF features. Remove all SFF
related stuff.
* Mask unsolicited ATA interrupts. This removes our primary source of
spurious interrupts and spurious interrupt handling can be tightened
up. There's no need to clear ATA interrupts by reading status
register either.
* Don't dance with IDMA_CTL_ATA_NIEN and simplify accesses to
IDMA_CTL.
* Inherit from sata_port_ops instead of ata_sff_port_ops.
* Don't initialize or use ioaddr. There's no need to map BAR0-4
anymore.

Use IDMA for ATAPI commands. Write and some misc commands time out
when executed using ATAPI_PROT_DMA but ATAPI_PROT_PIO works fine. As
PIO is driven by DMA too, it doesn't make any noticeable difference
for native SATA devices. inic_check_atapi_dma() is implemented to
force PIO for those ATAPI commands.
After this change, sata_inic162x issues all commands using IDMA.

Use IDMA for PIO and non-data commands. This allows sata_inic162x to
safely drive LBA48 devices. Kill inic_dev_config() which contains
code to reject LBA48 devices.
With this change, status checking in inic_qc_issue() to avoid hard
lock up after hotplug can go away too.

The modified driver on initio site has enough clue on how to use IDMA.
Use IDMA for ATA_PROT_DMA.
* LBA48 now works as long as it uses DMA (LBA48 devices still aren't
allowed as it can destroy data if PIO is used for any reason).
* No need to mask IRQs for read DMAs as IDMA_DONE is properly raised
after transfer to memory is actually completed. There will be some
spurious interrupts but host_intr will handle it correctly and
manipulating port IRQ mask interacts badly with the other port for
some reason, so command type dependent port IRQ masking is not used
anymore.

inic162x can't reliably read back TF or at least we don't know how to
do it yet. The only values which seem reliable are status and error.
This patch updates access to TF.
* implement inic_tf_read() which reads the TF area in mmio area
* implement custom inic_qc_fill_rtf() which only returns true if
status indicates device error. it'll be returning bogus addresses
for device errors but it'll be able to report why it failed at
least.
* implement custom inic_check_ready() and use ata_wait_after_reset()
instead of the SFF version.
* use inic_tf_read() for classification.
This is not perfect but it fixes hotplug detection failure and at
least makes the driver report 0's instead of random garbages while
reporting valid status and error for device errors.
