Userspace SRQs don't have a buffer allocated for them in the kernel, so
it doesn't make sense to set srq->last during initialization. In fact,
this can crash trying to follow a nonexistent buffer pointer.

The error handling paths in mthca_tavor_post_srq_recv() and
mthca_arbel_post_srq_recv() are quite bogus, the result of a
screwed up merge. Fix them so they work as intended.

In mthca_create_eq(), we call get_eqe() before setting eq->nent. This
is wrong, because get_eqe() uses eq->nent. Fix this, and clean up the
code a little while we're at it. (We got lucky with the current code,
because eq->nent was cleared to 0, which get_eqe() made happen to do
the right thing)

We got a little mixed up with what the backoff member holds in the
IPoIB multicast group structure: sometimes it was used as a number of
seconds, and sometimes it was used as a number of jiffies. Fix the
code so that backoff is always in seconds.

Fix posting first WQE for mem-free HCAs: we need to link to previous
WQE even in that case. While we're at it, simplify code for
Tavor-mode HCAs. We don't really need the conditional test there
either; we can similarly always link to the previous WQE.
Based on Michael S. Tsirkin's analogous fix for userspace libmthca.

The hardware reads the ACK timeout field from the most significant 5
bits of struct mthca_qp_path's ackto field, not the least significant
bits. This fix has the driver put the timeout in the right place.
Without this, we get a timeout that is 2^8 times too small.

From: Florin Malita <fmalita@gmail.com>
bond_init() is not releasing rtnl_sem after register_netdevice() and before
calling unregister_netdevice() (from bond_free_all()) in the exception
path. As the device registration is not completed (dev->reg_state ==
NETREG_REGISTERING), the call to unregister_netdevice() triggers
BUG_ON(dev->reg_state != NETREG_REGISTERED).

When doing ioctl HDIO_DRIVE_TASKFILE, the ide_task_t's request pointer is
never set, but flagged_taskfile and do_rw_taskfile pass it as a parameter
to the prehandler. The kernel will oops taskfile pio-out commands because
of this (taskfile pio-in doesn't use a prehandler). This fix sets the
request pointer at the time the request is created to stop this oops.

BUG fixes:
The driver used to allocate memory with spinlock held which has been
fixed in this patch.
The driver was printing the entire buffer when it received a invalid
entry in image_type. The fix is to only print a warning message and not
the buffer.
Usability enhancements:
It is possible that due to user error the /sys/class/firmware/dell_rbu
entries might be missing, this can happen if the user does the following
echo 1 > /sys/class/firmware/dell_rbu/loading
echo 0 > /sys/class/firmware/dell_rbu/loading
This will make the entries in /sys/class/firmware/ to disappear and the
only way get them back was bby unloading and loading the driver.
This patch makes the user recreate these entries by echoing init in to
image_type.
This patch has been tested with Libsmbios and Dell OpenManage.

Fix and simplify the workaround code for the 4GB boundary tx buffer
hardware bug.
1. Need to unmap the original SKB's dma addresses if a new SKB cannot
be allocated.
2. Need to pass the base flag to tigon3_4gb_hwbug_workaround() or TSO
won't work properly.
3. The guilty entry and length parameters for
tigon3_4gb_hwbug_workaround() are removed as they are not necessary.
4. Remove assumption that only one fragment can hit the 4GB boundary.
Another fragment can hit 8GB for example.

Make sure we that completion is the final action we take; prior to this

Reported by: walt <wa1ter@myrealbox.com>
"I routinely switch the console font during bootup to
8x8 so I can get 50 lines per screen. Until 09 Sept,
just changing to the small font automatically gave me
all 50 lines -- but now I'm only getting 25 lines even
with the small font. The bottom half of the screen
displays the text that already scrolled off the top."
This bug is due to an erroneous check in the recently added hook,
vgacon_resize(). It checks the new height against the original number of
rows of the console. Because the original number of rows depends on both
the scanline and the font height, check it instead against the
scanline/fontheight.
