This patch fixes bug in macro radix_tree_for_each_contig().
If radix_tree_next_slot() sees NULL in next slot it returns NULL, but following
radix_tree_next_chunk() switches iterating into next chunk. As result iterating
becomes non-contiguous and breaks vfs "splice" and all its users.

kvm_set_irq() has an internal buffer of three irq routing entries, allowing
connecting a GSI to three IRQ chips or on MSI. However setup_routing_entry()
does not properly enforce this, allowing three irqchip routes followed by
an MSI route to overflow the buffer.
Fix by ensuring that an MSI entry is added to an empty list.

Many TVs and A/V receivers don't work with this bit set. Problem was
confirmed using: Onkyo TX-SR605, Sony BRAVIA KDL-52X3500, Sony BRAVIA
KDL-40S40xx. In theory this bit shouldn't affect audio engine when
feeding it with data, however it seems it does. Driver fglrx doesn't set
that bit in any of the above cases.

Pull frontswap feature from Konrad Rzeszutek Wilk:
"Frontswap provides a "transcendent memory" interface for swap pages.
In some environments, dramatic performance savings may be obtained

some changes to the existing backends."

This pull request came in before the merge window even opened, it got
delayed to after the merge window by me just wanting to make sure it had

Empirical evidence suggests that we need to: On at least one ivb
machine when running the hangman i-g-t test, the rings don't properly
initialize properly - the RING_START registers seems to be stuck at
all zeros.
Holding forcewake around this register init sequences makes chip reset
reliable again. Note that this is not the first such issue:

drm/i915: Add wait_for in init_ring_common
added delay loops to make RING_START and RING_CTL initialization
reliable on the blt ring at boot-up. So I guess it won't hurt if we do
this unconditionally for all force_wake needing gpus.
To avoid copy&pasting of the HAS_FORCE_WAKE check I've added a new
intel_info bit for that.
v2: Fixup missing commas in static struct and properly handling the
error case in init_ring_common, both noticed by Jani Nikula.

By correctly describing the rinbuffers as being in the GTT domain, it
appears that we are more careful with the management of the CPU cache
upon resume and so prevent some coherency issue when submitting commands
to the GPU later. A secondary effect is that the debug logs are then
consistent with the actual usage (i.e. they no longer describe the
ringbuffers as being in the CPU write domain when we are accessing them
through an wc iomapping.)

Cyrill Gorcunov reports that I broke the fdinfo files with commit
30a08bf2d31d ("proc: move fd symlink i_mode calculations into
tid_fd_revalidate()"), and he's quite right.
The tid_fd_revalidate() function is not just used for the <tid>/fd
symlinks, it's also used for the <tid>/fdinfo/<fd> files, and the
permission model for those are different.
So do the dynamic symlink permission handling just for symlinks, making
the fdinfo files once more appear as the proper regular files they are.
Of course, Al Viro argued (probably correctly) that we shouldn't do the
symlink permission games at all, and make the symlinks always just be
the normal 'lrwxrwxrwx'. That would have avoided this issue too, but
since somebody noticed that the permissions had changed (which was the
reason for that original commit 30a08bf2d31d in the first place), people
do apparently use this feature.
[ Basically, you can use the symlink permission data as a cheap "fdinfo"
replacement, since you see whether the file is open for reading and/or
writing by just looking at st_mode of the symlink. So the feature
does make sense, even if the pain it has caused means we probably
shouldn't have done it to begin with. ]

Commit e605b743f33d ("IB/mlx4: Increase the number of vectors (EQs)
available for ULPs") didn't handle correctly the case where there
aren't enough MSI-X vectors to increase the number of EQs, so only the
legacy EQs are allocated. This results in an attempt to memset() to
zero the EQ table which was never allocated and a kernel crash.
Fix this by checking in the teardown flow if the table of EQs was ever
allocated. Also remove some unneeded setting to zero of the EQ
related fields in struct mlx4_ib_dev.

Initial IVB support went into turbostat in Linux-3.1:
553575f1ae048aa44682b46b3c51929a0b3ad337
(tools turbostat: recognize and run properly on IVB)
However, when running on IVB, turbostat would fail
to report the new couters added with SNB, c7, pc2 and pc7.
So in scenarios where these counters are non-zero on IVB,
turbostat would report erroneous residencey results.
In particular c7 time would be added to c1 time,
since c1 time is calculated as "that which is left over".
Also, turbostat reports MHz capabilities when passed
the "-v" option, and it would incorrectly report 133MHz
bclk instead of 100MHz bclk for IVB, which would inflate
GHz reported with that option.
This patch is a backport of a fix already included in turbostat v2.

Linux 3.4 included a modification to turbostat to
lower cross-call overhead by using scheduler affinity:
15aaa34654831e98dd76f7738b6c7f5d05a66430
(tools turbostat: reduce measurement overhead due to IPIs)
In the use-case where turbostat forks a child program,
that change had the un-intended side-effect of binding
the child to the last cpu in the system.
This change removed the binding before forking the child.
This is a back-port of a fix already included in turbostat v2.
