Commit 32fcfd40715e ("make vfree() safe to call from interrupt
contexts") made it safe to do vfree directly from the RCU callback,
which allows us to simplify ipc/util.c a lot by getting rid of the
differences between vmalloc/kmalloc memory.

Commit 8ad227ff89a7 ("net: vlan: add 802.1ad support") added some new
NETIF_F_* features bits, but it added them in the middle of existing
values.
Userland depends upon the flag bits via the per-netdevice 'flags' sysfs
file.
So restore the previous ordering by adding the new flags at the end.

This is to allow debugging of userspace program not freeing buffer
after, which is basicly a memory leak. This print the list of all
gem object along with their size and placement (VRAM,GTT,CPU) and
with the pid of the task that created them.

This adds the API for userspace to instantiate an XICS device in a VM
and connect VCPUs to it. The API consists of a new device type for
the KVM_CREATE_DEVICE ioctl, a new capability KVM_CAP_IRQ_XICS, which
functions similarly to KVM_CAP_IRQ_MPIC, and the KVM_IRQ_LINE ioctl,
which is used to assert and deassert interrupt inputs of the XICS.
The XICS device has one attribute group, KVM_DEV_XICS_GRP_SOURCES.
Each attribute within this group corresponds to the state of one
interrupt source. The attribute number is the same as the interrupt
source number.
This does not support irq routing or irqfd yet.

The full mcpm layer is not likely to be relevant to v6 based
platforms, so a multiplatform kernel won't use that code if booted
on v6 hardware.
This patch modifies the AFLAGS for affected mcpm .S files to

omapfb requires the panel drivers to have been probed when omapfb is
initialized. omapfb does not support insertion of new panels after its
probe. This causes a problem in case omapdss or the panel probes have
been deferred due to EPROBE_DEFER error, as omapfb won't find any
displays.
As a quick fix, this patch changes the omapfb probe so that if omapfb
does not find any displays, it'll return EPROBE_DEFER. This is not
perfect, as with a board with no displays, omapfb will get deferred
forever. Also, if the board has multiple displays, but only some of them
have been probed, omapfb will start and leave the unprobed displays out.

omapfb requires the panels to have been probed before omapfb's probe. We
currently manage that by having omapfb in late initcall level. However,
a much simpler way is to just change the makefile so that omapfb is
after the panel drivers.

Commit 100c826235793345efe06b3558cc9d36166b1e26 (OMAPDSS: DPI: use new
clock calculation code) breaks dpi.c compilation if DSI is not enabled
in the kernel configuration.
Fix compilation by adding dummy inline functions for the ones that dpi.c
references. The functions will never be called, as dpi.c knows that
there is no DSI device available.

Port over the mgag200 fix to cirrus as it suffers the same issue.
On F19 testing, it was noticed we get a lot of errors in dmesg
about being unable to reserve the buffer when plymouth starts,
this is due to the buffer being in the process of migrating,
so it makes sense we can't reserve it.
In order to deal with it, this adds delayed updates for the dirty
updates, when the bo is unreservable, in the normal console case
this shouldn't ever happen, its just when plymouth or X is
pushing the console bo to system memory.

We are getting low on cpu feature bits. So rather than add a separate bit for
every new Power8 feature, add a bit for arch 2.07 server catagory and use that
instead.
Hijack the value we had for BCTAR, but swap the value with CFAR so that all the
ARCH defines are together.
Note we don't touch CPU_FTR_TM, because it is conditionally enabled if
the kernel is built with TM support.
