Chris Metcalf 4455b1191c hvc_console: use "*_console" nomenclature to avoid modpost warning.
The use of "hvc_con_driver" as the name for a file-static "struct
console" with a ".setup" field pointing to an __init function causes
a modpost warning, since a non-initdata structure points to init code.
Using "hvc_console" as the name triggers the hacky "*_console"
workaround in modpost to silence the warning, and is the same thing
that most of the other console drivers already do.

I made the same change in hvsi.c since I happened to notice it was
likely to suffer from the same problem.

Jesse Barnes 023eb571a1 drm: correctly update connector DPMS status in drm_fb_helper
We don't currently update the DPMS status of the connector (both in the
connector itself and the connector's DPMS property) in the fb helper
code.  This means that if the kernel FB core has blanked the screen,
sysfs will still show a DPMS status of "on".  It also means that when X
starts, it will try to light up the connectors, but the drm_crtc_helper
code will ignore the DPMS change since according to the connector, the
DPMS status is already on.

Fixes https://bugs.freedesktop.org/show_bug.cgi?id=28436 (the annoying
"my screen was blanked when I started X and now it won't light up" bug).

Francisco Jerez 5870a4d97d drm/ttm: Allocate the page pool manager in the heap.
Repeated ttm_page_alloc_init/fini fails noisily because the pool
manager kobj isn't zeroed out between uses (we could do just that but
statically allocated kobjects are generally considered a bad thing).
Move it to kzalloc'ed memory.

Note that this patch drops the refcounting behavior of the pool
allocator init/fini functions: it would have led to a race condition
in its current form, and anyway it was never exploited.

This fixes a regression with reloading kms modules at runtime, since
page allocator was introduced.

If qib_init() fails, the driver fails to free memory, unregister
device files, and unregister with the PCIe framework. The driver will
unload without error but a subsequent driver load will cause the

serdes microcode separately and not installing the microcode file.

Steve Wise 1973e8b8ed RDMA/cxgb4: Avoid false GTS CIDX_INC overflows
The T4 IQ hw design assumes CIDX_INC credits will be returned on a
regular basis and always before the CIDX counter crosses over the PIDX
counter.  For RDMA CQs, however, returning CIDX_INC credits is only
needed and desired when and if the CQ is armed for notification.  This
can lead to a GTS write returning credits that causes the HW to reject
the credit update because it causes CIDX to pass PIDX.  Once this
happens, the CIDX/PIDX counters get out of whack and an application
can miss a notification and get stuck blocked awaiting a notification.

To avoid this, we allocate the HW IQ 2x times the requested size.
This seems to avoid the false overflow failures.  If we see more
issues with this, then we'll have to add code in the poll path to
return credits periodically like when the amount reaches 1/2 the queue
depth).  I would like to avoid this as it adds a PCI write transaction
for applications that never arm the CQ (like most MPIs).

Jon Mason 4a49043223 s2io: resolve statistics issues
This patch resolves a number of issues in the statistics gathering of
the s2io driver.

On Xframe adapters, the received multicast statistics counter includes
pause frames which are not indicated to the driver.  This can cause
issues where the multicast packet count is higher than what has actually
been received, possibly higher than the number of packets received.

The driver software counters are replaced with the adapter hardware
statistics for rx_packets, rx_bytes, and tx_bytes.  It also uses the
overflow registers to determine if the statistics wrapped the 32bit
register (removing the window of having a statistic value less than the
previous call).  rx_length_errors statistic now includes undersized
packets in addition to oversized packets in its counting.  Finally,
rx_crc_errors are now being counted.

John Fastabend f0796d5c73 net: decreasing real_num_tx_queues needs to flush qdisc
Reducing real_num_queues needs to flush the qdisc otherwise
skbs with queue_mappings greater then real_num_tx_queues can
be sent to the underlying driver.

The flow for this is,

dev_queue_xmit()
	dev_pick_tx()
		skb_tx_hash()  => hash using real_num_tx_queues
		skb_set_queue_mapping()
	...
	qdisc_enqueue_root() => enqueue skb on txq from hash
...
dev->real_num_tx_queues -= n
...
sch_direct_xmit()
	dev_hard_start_xmit()
		ndo_start_xmit(skb,dev) => skb queue set with old hash

skbs are enqueued on the qdisc with skb->queue_mapping set
0 < queue_mappings < real_num_tx_queues.  When the driver
decreases real_num_tx_queues skb's may be dequeued from the
qdisc with a queue_mapping greater then real_num_tx_queues.

This fixes a case in ixgbe where this was occurring with DCB
and FCoE. Because the driver is using queue_mapping to map
skbs to tx descriptor rings we can potentially map skbs to
rings that no longer exist.

Daniel J Blueman 980533b018 correct console log level when ERST ACPI table is not found
When booting 2.6.35-rc3 on a x86 system without an ERST ACPI table with
the 'quiet' option, we still observe an "ERST: Table is not found!"
warning.

Quiesce it to the same info log level as the other 'table not found'
warnings.

Linus Torvalds 985b823b91 drm/i915: fix hibernation since i915 self-reclaim fixes
Since commit 4bdadb9785 ("drm/i915:
Selectively enable self-reclaim"), we've been passing GFP_MOVABLE to the
i915 page allocator where we weren't before due to some over-eager
removal of the page mapping gfp_flags games the code used to play.

This caused hibernate on Intel hardware to result in a lot of memory
corruptions on resume.  See for example

Jesse Barnes dd1ea37d92 drm/i915: change default panel fitting mode to preserve aspect ratio
We did this a long time ago in the DDX driver, but now this fix belongs
in the kernel.

Preserving the aspect ratio is a nicer default.

Fixes https://bugs.freedesktop.org/show_bug.cgi?id=18033.
