Inline data segments in send WQEs are not allowed to cross a 64 byte
boundary. We use inline data segments to hold the UD headers for MLX
QPs (QP0 and QP1). A send with GRH on QP1 will have a UD header that
is too big to fit in a single inline data segment without crossing a
64 byte boundary, so split the header into two inline data segments.

Upcoming firmware introduces command interface revision 3, which
changes the way port capabilities are queried and set. Update the
driver to handle both the new and old command interfaces by adding a
new MLX4_FLAG_OLD_PORT_CMDS that it is set after querying the firmware
interface revision and then using the correct interface based on the
setting of the flag.

When compacting CQ entries, we need to set the correct value of the

The calculation of max_inline_data in set_kernel_sq_size() is bogus,
since it doesn't take into account the fact that inline segments may
not cross a 64-byte boundary, and hence multiple inline segments will
probably need to be used to post large inline sends.
We don't support inline sends for kernel QPs anyway, so there's no
point in doing this calculation anyway, since the field is just zeroed
out a little later. So just delete the bogus calculation.

New ConnectX firmware introduces FW command interface revision 2,
which requires that for each QP, a chunk of send queue entries (the
"headroom") is kept marked as invalid, so that the HCA doesn't get
confused if it prefetches entries that haven't been posted yet. Add
code to the driver to do this, and also update the user ABI so that
userspace can request that the prefetcher be turned off for userspace
QPs (we just leave the prefetcher on for all kernel QPs).
Unfortunately, marking send queue entries this way is confuses older
firmware, so we change the driver to allow only FW command interface
revisions 2. This means that users will have to update their firmware
to work with the new driver, but the firmware is changing quickly and
the old firmware has lots of other bugs anyway, so this shouldn't be too
big a deal.

next_port should be between sysctl_local_port_range[0] and [1].
However, it is initially set to a random value with get_random_bytes().
If the value is negative when treated as a signed integer, next_port
can end up outside the expected range because of the result of the %
operator being negative.

The code in __mlx4_ib_modify_qp() overwrites context->params1 after
the RNR retry parameter is ORed in, which results in the RNR retry
parameter always being set to 0. Fix this by moving where we OR in

context->params1.

HCA firmware with incompatible changes to the FW commmand interface is
coming soon. Add a check of the interface revision during
initialization and bail out if the firmware advertises a revision that
the driver doesn't know about. This will avoid strange failures later
if the driver goes on using the wrong interface revision.

We may call mlx4_dispatch_event() before mlx4_register_device() is
called for a device, because for example a catastrophic error happens
immediately after we enable interrupts. Therefore priv->ctx_list and
priv->ctx_lock need to be initialized earlier.
This bug was actually exposed by the MSI-X bug that returned IRQ numbers
to drivers in reverse order, so that the first FW command
interrupt looked to mlx4 like a catastrophic error.

The reserved6 field should be 64 bits, not just 16 bits. Without
this, the structure does not match the hardware layout on 32-bit
architectures: the db_rec_addr field ends up at offset 52 instead of
offset 56. The bug slipped by because the alignment of __be64 members
ends up putting it in the right place on x86-64.

After SRST, libata used to wait for nsect/lbal to be set to 1/1 for
the slave device. However, some ATAPI devices don't set nsect/lbal
after SRST and the wait itself isn't too useful as we're gonna wait
for !BSY right after that anyway.
Before reset-seq update, nsect/lbal wait failure used to be ignored
and caused 30sec delay during detection. After reset-seq, all
timeouts are considered error conditions making libata fail to detect
such ATAPI devices.
This patch limits nsect/lbal wait to around 100ms. This should give
acceptable behavior to such ATAPI devices while not disturbing the
heavily used code path too much.

The ata IRQ ack functions are only used when debugging. Unfortunately
almost every controller that calls them can cause crashes in some
configurations as there are missing checks for bmdma presence.
In addition ata_port_start insists of installing DMA buffers and pad
buffers for controllers regardless. The SFF controllers actually need to
make that decision dynamically at controller setup time and all need the
same helper - so we add ata_sff_port_start. Future patches will switch
the SFF drivers to use this.

Most drivers don't seem to fill out the host->irq field, resulting in the
wrong (no) irq being reported at probe time. For example, sil24 on my system:
ata1: SATA max UDMA/100 cmd 0xd00008009001f000 ctl 0x0000000000000000 bmdma 0x0000000000000000 irq 0

This patch moves flexcop-dma (currently used only by flexcop-pci) to

as reported by Geert Uytterhoeven <geert@linux-m68k.org>:
drivers/media/dvb/b2c2/flexcop-dma.c uses the PCI DMA API, but
DVB_B2C2_FLEXCOP doesn't depend on PCI, causing the following problem on
PCI-less systems:
| linux/drivers/media/dvb/b2c2/flexcop-dma.c:20: warning: implicit declaration of function 'pci_alloc_consistent'
| linux/drivers/media/dvb/b2c2/flexcop-dma.c:20: warning: implicit declaration of function 'pci_alloc_consistent'
Apparently this is the flexcop DMA core, which is used by both
DVB_B2C2_FLEXCOP_PCI and DVB_B2C2_FLEXCOP_USB.

workhandler
Sliced VBI transfers use PIO instead of DMA. This was done inside the
interrupt handler, but since PIO accesses are very slow this meant that
a lot of time was spent inside the interrupt handler. All PIO copies are
now moved to a workqueue. This should fix various issues with missing time
ticks and remote key hits.

If this mutex_lock_interruptible() does fail due to signal_pending() then the
state of the driver will get trashed in interesting ways, because userspace
cannot and will not retry the close().

If the SAA7111 device is powered down, and requires re-initialisation when
the V4L device is opened (as on the NetWinder), the SAA7111 driver gets
completely confused about the current settings.
The problem is centred around the way the driver keeps _two_ cached copies
of the current settings - one of the struct video_picture settings, and one
of the registers.
When the decoder is re-initailised, the cached register settings are
overwritten, as are the values in the hardware registers. However, the
cached video_picture settings are not.
Resolve this by removing the useless and buggy second level of caching for
video_picture. Instead, provide a function which updates register values
if and only if the value we are going to write to the register has changed.
