This fixes CVE-2017-12193.

Fix a case in the assoc_array implementation in which a new leaf is
added that needs to go into a node that happens to be full, where the
existing leaves in that node cluster together at that level to the
exclusion of new leaf.

What needs to happen is that the existing leaves get moved out to a new
node, N1, at level + 1 and the existing node needs replacing with one,
N0, that has pointers to the new leaf and to N1.

The code that tries to do this gets this wrong in two ways:

 (1) The pointer that should've pointed from N0 to N1 is set to point
     recursively to N0 instead.

 (2) The backpointer from N0 needs to be set correctly in the case N0 is
     either the root node or reached through a shortcut.

Fix this by removing this path and using the split_node path instead,
which achieves the same end, but in a more general way (thanks to Eric
Biggers for spotting the redundancy).

The problem manifests itself as:

By convention the first 6 bits of F30 Ctrl 2 and 3 are used to signify
GPIOs which are connected to buttons. Additional GPIOs may be used as
input GPIOs to signal the touch controller of some event
(ie disable touchpad). These additional GPIOs may meet the criteria of
a button in rmi_f30_is_valid_button() but should not be considered
buttons. This patch limits the GPIOs which are mapped to buttons to just
the first 6.

This reverts commit ce56a86e.

There's unanticipated interaction with some boot parameters like 'mem=',
which now cause the new checks via valid_mmap_phys_addr_range() to be too
restrictive, crashing a Qemu bootup in fact, as reported by Fengguang Wu.

So while the motivation of the change is still entirely valid, we
need a few more rounds of testing to get it right - it's way too late
after -rc6, so revert it for now.

When a workload is too heavy to finish it in gpu hang check timer
intervals(1.5), gpu hang check function will check ACTHD register
value to decide whether gpu is real dead or not. On real hw,
ACTHD is updated by HW when workload is running, then host kernel
won't think it is gpu hang. while guest kernel always read a constant
ACTHD value as GVT doesn't supply ACTHD emulate handler, then
guest kernel detects a fake gpu hang.

To remove such guest fake gpu hang, this patch supply ACTHD

  42.2.  The specific cause is that and attempt to open a PF_LOCAL socket
  gets EACCES.  This means that networking doesn't function on a system

Sadly, the developers involved seemed to be in denial for several weeks
about this, delaying the revert.  This has not been a good release for
the security subsystem, and this area needs to change development
practices.

  PM / QoS: Fix device resume latency PM QoS

The introduction of {map/swizzle}_irq() hooks in the struct pci_host_bridge
allowed to replace the pci_fixup_irqs() PCI IRQ allocation in alpha arch
PCI code with per-bridge map/swizzle functions with commit 0e4c2eeb
("alpha/PCI: Replace pci_fixup_irqs() call with host bridge IRQ mapping
hooks").

As a side effect of converting PCI IRQ allocation to the struct
pci_host_bridge {map/swizzle}_irq() hooks mechanism, the actual PCI IRQ
allocation function (ie pci_assign_irq()) is carried out per-device in
pci_device_probe() that is called when a PCI device driver is about to be
probed.

This means that, for drivers compiled as loadable modules, the actual PCI
device IRQ allocation can now happen after the system has booted so the
struct pci_host_bridge {map/swizzle}_irq() hooks pci_assign_irq() relies on
must stay valid after the system has booted so that PCI core can carry out
PCI IRQ allocation correctly.

Most of the alpha board structures pci_map_irq() and pci_swizzle() hooks
(that are used to initialize their struct pci_host_bridge equivalent
through the alpha_mv global variable - that represents the struct
alpha_machine_vector of the running kernel) are marked as
__init/__initdata; this causes freed memory dereferences when PCI IRQ
allocation is carried out after the kernel has booted (ie when loading PCI
drivers as loadable module) because when the kernel tries to bind the PCI
device to its (module) driver, the function pci_assign_irq() is called,
that in turn retrieves the struct pci_host_bridge {map/swizzle}_irq() hooks
to carry out PCI IRQ allocation; if those hooks are marked as __init
code/__initdata they point at freed/invalid memory.

Fix the issue by removing the __init/__initdata markers from all subarch
struct alpha_machine_vector.pci_map_irq()/pci_swizzle() functions (and
data).

Commit 96edd61d ("xen/balloon: don't
online new memory initially") introduced a regression when booting a
HVM domain with memory less than mem-max: instead of ballooning down
immediately the system would try to use the memory up to mem-max
resulting in Xen crashing the domain.

For HVM domains the current size will be reflected in Xenstore node
memory/static-max instead of memory/target.

Additionally we have to trigger the ballooning process at once.
