The current davinci SPI driver, in DMA mode, is limited to 65535
words for a single transfer. Modify the driver by configuring a
3 dimensional EDMA transfer to support up to 65535x65535

The davinci spi driver provides an option to use DMA transfers for
data. In the dma_map_single() call, the driver is passing the
number of words to be transfered for the mapping size. It should
be the number of bytes.Signed-off-by: Michael Williamson

mpc23s17 is very similar to the mcp23s08, except that registers are 16bit

This fixes a bug introduced by 807e8e40673d ("mmc: Fix sd/sdio/mmc
initialization frequency retries") that prevented SDIO drivers from
performing SDIO commands in their probe routines -- the above patch
called mmc_claim_host() before sdio_add_func(), which causes a deadlock
if an external SDIO driver calls sdio_claim_host().Fix tested on an OLPC XO-1.75 with libertas on SDIO.

Andi Kleen narrowed his GPU hangs on his Sugar Bay (SNB desktop) rev 09
down to the use of GPU semaphores, and we already know that they appear
broken up to Huron River (mobile) rev 08. (I'm optimistic that disabling
GPU semaphores is simply hiding another bug by the latency and
side-effects of the additional device interaction it introduces...)However, use of semaphores is a massive performance improvement... Only
as long as the system remains stable. Enable at your peril.Reported-by: Andi Kleen

If a virtio-console device gets unplugged while a port is open, a
subsequent close() call on the port accesses vqs to free up buffers.
This can lead to a crash.The buffers are already freed up as a result of the call to
unplug_ports() from virtcons_remove(). The fix is to simply not access
vq information if port->portdev is NULL.Reported-by: juzhang

Whilst the GT is powered down (rc6), writes to MMADDR are placed in a
FIFO by the System Agent. This is a limited resource, only 64 entries, of
which 20 are reserved for Display and PCH writes, and so we must take
care not to queue up too many writes. To avoid this, there is counter
which we can poll to ensure there are sufficient free entries in the
fifo."Issuing a write to a full FIFO is not supported; at worst it could
result in corruption or a system hang."Reported-and-Tested-by: Matt Turner

As it turns out, userspace already depends upon being able to enable
tiling on existing bo which it promises to be large enough for its

Pass down the correct node for a transparent hugepage allocation. Most
callers continue to use the current node, however the hugepaged daemon
now uses the previous node of the first to be collapsed page instead.
This ensures that khugepaged does not mess up local memory for an
existing process which uses local policy.The choice of node is somewhat primitive currently: it just uses the
node of the first page in the pmd range. An alternative would be to
look at multiple pages and use the most popular node. I used the
simplest variant for now which should work well enough for the case of
all pages being on the same node.[akpm@linux-foundation.org: coding-style fixes]

This driver causes hard lockups, when the active clock soure is jiffies.
The reason is that it loops with interrupts disabled waiting for a
timestamp to be reached by polling getnstimeofday(). Though with a
jiffies clocksource, when that code runs on the same CPU which is
responsible for updating jiffies, then we loop in circles for ever
simply because the timer interrupt cannot update jiffies. So both UP
and SMP can be affected.There is no easy fix for that problem so make it depend on BROKEN for
now.Signed-off-by: Thomas Gleixner
