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 ce56a86e2ade45d052b3228cdfebe913a1ae7381.
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
mmio read handler which read real HW ACTHD register directly.

This reverts commit 651e28c5537abb39076d3949fb7618536f1d242e.
This caused a regression:
"The specific problem is that dnsmasq refuses to start on openSUSE Leap
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
with a 4.14-rc2 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.

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 0e4c2eeb758a
("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 96edd61dcf44362d3ef0bed1a5361e0ac7886a63 ("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.

rdma_nl_rcv_msg() checks to see if it should use the .dump() callback
or the .doit() callback. The check is done with this check:
if (flags & NLM_F_DUMP) ...
The NLM_F_DUMP flag is two bits (NLM_F_ROOT | NLM_F_MATCH).
When an RDMA_NL_LS message (response) is received, the bit used for
indicating an error is the same bit as NLM_F_ROOT.
NLM_F_ROOT == (0x100) == RDMA_NL_LS_F_ERR.
ibacm sends a response with the RDMA_NL_LS_F_ERR bit set if an error
occurs in the service. The current code then misinterprets the
NLM_F_DUMP bit and trys to call the .dump() callback.

Additionally, make sure that the .dump() callback is not NULL
before calling it.

query_info() doesn't use the InputBuffer field of the QUERY_INFO
request, therefore according to [MS-SMB2] it must:
a) set the InputBufferOffset to 0
b) send a zero-length InputBuffer
Doing a) is trivial but b) is a bit more tricky.
The packet is allocated according to it's StructureSize, which takes
into account an extra 1 byte buffer which we don't need
here. StructureSize fields must have constant values no matter the
actual length of the whole packet so we can't just edit that constant.
Both the NetBIOS-over-TCP message length ("rfc1002 length") L and the
iovec length L' have to be updated. Since L' is computed from L we
just update L by decrementing it by one.

In case gntdev_mmap() succeeds only partially in mapping grant pages
it will leave some vital information uninitialized needed later for
cleanup. This will lead to an out of bounds array access when unmapping
the already mapped pages.
So just initialize the data needed for unmapping the pages a little bit
earlier.

Marios Titas running a Haskell program noticed a problem with fuse's
readdirplus: when it is interrupted by a signal, it skips one directory
entry.
The reason is that fuse erronously updates ctx->pos after a failed
dir_emit().
The issue originates from the patch adding readdirplus support.
