bf6b47deb4 IB/mlx4: Fix memory leaks in ib_link_query_port()
If the call to mlx4_MAD_IFC() fails in ib_link_query_port() we will
currently do 'return err;' which will leak 'in_mad' and 'out_mad'.  We
should instead do 'goto out;' where we'll properly free the memory we
previously allocated.

a9e7432319 IB/mad: Don't send response for failed MADs
Commit 0b30704304 ("IB/mad: Return error response for unsupported
MADs") does not failed MADs (eg those that return
IB_MAD_RESULT_FAILURE) properly -- these MADs should be silently
discarded. (We should not force the lower-layer drivers to return
SUCCESS | CONSUMED in this case, since the MAD is NOT successful).
Unsupported MADs are not failures -- they return SUCCESS, but with an
"unsupported error" status value inside the response MAD.

840777de53 IB/mad: Set 'D' bit in response for unhandled MADs
Commit 0b30704304 ("IB/mad: Return error response for unsupported
MADs") does not handle directed-route MADs properly -- it fails to set
the 'D' bit in the response MAD status field.  This is a problem for
SmInfo MADs when the receiver does not have an SM running.

f8262d4768 PM / Hibernate: fix the number of pages used for hibernate/thaw buffering
Hibernation regression fix, since 3.2.

Calculate the number of required free pages based on non-high memory
pages only, because that is where the buffers will come from.

Commit 081a9d043c introduced a new buffer
page allocation logic during hibernation, in order to improve the
performance. The amount of pages allocated was calculated based on total
amount of pages available, although only non-high memory pages are
usable for this purpose. This caused hibernation code to attempt to over
allocate pages on platforms that have high memory, which led to hangs.

151b612847 USB: EHCI: fix crash during suspend on ASUS computers
This patch (as1545) fixes a problem affecting several ASUS computers:
The machine crashes or corrupts memory when going into suspend if the
ehci-hcd driver is bound to any controllers.  Users have been forced
to unbind or unload ehci-hcd before putting their systems to sleep.

After extensive testing, it was determined that the machines don't
like going into suspend when any EHCI controllers are in the PCI D3
power state.  Presumably this is a firmware bug, but there's nothing
we can do about it except to avoid putting the controllers in D3
during system sleep.

The patch adds a new flag to indicate whether the problem is present,
and avoids changing the controller's power state if the flag is set.
Runtime suspend is unaffected; this matters only for system suspend.
However as a side effect, the controller will not respond to remote
wakeup requests while the system is asleep.  Hence USB wakeup is not
functional -- but of course, this is already true in the current state
of affairs.

This fixes Bugzilla .

a2cd62ec9a staging: tidspbridge: remove usage of OMAP2_L4_IO_ADDRESS
Instead now use ioremap. This is needed for 3.4 since this change
emerged in mainline during one of the previous rc cycles.

These solves the following compilation breaks:

drivers/staging/tidspbridge/core/tiomap3430.c:
    In function ‘bridge_brd_start’:
drivers/staging/tidspbridge/core/tiomap3430.c:425:4:
    error: implicit declaration of function ‘OMAP2_L4_IO_ADDRESS’

drivers/staging/tidspbridge/core/wdt.c:56:2:
    error: implicit declaration of function ‘OMAP2_L4_IO_ADDRESS’

For control registers a new function needs to be defined so we
can get rid of a layer violation, but that approach must be queued
for the next merge window.

c562ccbf58 staging:iio:meter:ad7758 use iio_sw_buffer_preenable to avoid code repition
Using this generic function adds a little overhead to a slow path but
reduces the amount of code repitition in exchange.

Now the generic function caches the scan size a lot of what was here
was redundant and is removed.

Here some addition elements are needed, but this generic function cuts
down on the amount of code.

This is not a fast path, so although the original code was more consise
use the generic case to cut down on code repitition.

f1264809eb staging:iio: scan_index_timestamp move to iio_dev from buffer
This is just a locally cached value that is device specific (rather
than buffer specific.) Hence it wants to come out of the buffer before
we add multiple buffer support.

Principal reason is to make later patches more coherent and easier to review
but this set in itself separates a logical entity out nicely wihin the code.
