With the clock assignment device tree changes, the clocks get
initialized properly but the search for those clocks fails with
errors:
[ 0.000000] i.MX clk 4: register failed with -17
[ 0.000000] i.MX clk 5: register failed with -17
This is because the module can't find those clocks anymore, and
tries to initialize fixed clocks with the same name.
Get the clock modules input clocks from the assigned clocks by
default by using of_clk_get_by_name(). If this function returns
not a valid clock, fall back to the old behaviour and search the
input clock from the device tree's /clocks/$name node.

selection was dropped by savedefconfig for imx_v4_v5_defconfig and

So far, the required PLL's (PLL1/PLL2/PLL5) have been initialized
by boot loader and the kernel code defined fixed rates according
to those default configurations. Beginning with the USB PLL7 the
code started to initialize the PLL's itself (using imx_clk_pllv3).
However, since commit dc4805c2e7
(ARM: imx: remove ENABLE and BYPASS bits from clk-pllv3 driver)
imx_clk_pllv3 no longer takes care of the ENABLE and BYPASS bits,
hence the USB PLL were not configured correctly anymore.
This patch not only fixes those USB PLL's, but also makes use of
the imx_clk_pllv3 for all PLL's and alignes the code with the PLL
support of the i.MX6 series.

the m25p80.c driver and the SPI NOR library framework, we omitted proper
listing of the SPI device IDs. This means m25p80.c wouldn't auto-load
(modprobe) properly when built as a module. For now, we duplicate the device
IDs into both modules.
* The OMAP / ELM modules were depending on an implicit link ordering. Use
deferred probing so that the new link order (in 3.18-rc) can still allow for
successful probing.

So calling that function is doubly wrong, and will just cause an oops.

In order to access the shadow VMCS, we need to load it. At this point,
vmx->loaded_vmcs->vmcs and the actually loaded one start to differ. If
we now get preempted by Linux, vmx_vcpu_put and, on return, the
vmx_vcpu_load will work against the wrong vmcs. That can cause
copy_shadow_to_vmcs12 to corrupt the vmcs12 state.
Fix the issue by disabling preemption during the copy operation.
copy_vmcs12_to_shadow is safe from this issue as it is executed by
vmx_vcpu_run when preemption is already disabled before vmentry.
This bug is exposed by running Jailhouse within KVM on CPUs with
shadow VMCS support. Jailhouse never expects an interrupt pending
vmexit, but the bug can cause it if, after copy_shadow_to_vmcs12
is preempted, the active VMCS happens to have the virtual interrupt
pending flag set in the CPU-based execution controls.

Commit d1442d85cc ("KVM: x86: Handle errors when RIP is set during far

incorrect evaluation, far jump to segment with L bit cleared (i.e., 32-bit
segment) and RIP with any of the high bits set (i.e, RIP[63:32] != 0) set may
not trigger #GP. As we know, this imposes a security problem.

Pull ACPI and power management fixes from Rafael Wysocki:
"These are fixes received after my previous pull request plus one that
has been in the works for quite a while, but its previous version
caused problems to happen, so it's been deferred till now.
Fixed are two recent regressions (MFD enumeration and cpufreq-dt),
ACPI EC regression introduced in 3.17, system suspend error code path
regression introduced in 3.15, an older bug related to recovery from
failing resume from hibernation and a cpufreq-dt driver issue related
to operation performance points.
Specifics:
- Fix a crash on r8a7791/koelsch during resume from system suspend
caused by a recent cpufreq-dt commit (Geert Uytterhoeven).
- Fix an MFD enumeration problem introduced by a recent commit adding
ACPI support to the MFD subsystem that exposed a weakness in the

Pull PCI fixes from Bjorn Helgaas:
"These changes, intended for v3.18, fix:
Sysfs
- Fix "enable" filename change (Greg Kroah-Hartman)
An unintentional sysfs filename change in commit 5136b2da77
("PCI: convert bus code to use dev_groups"), which appeared in
v3.13, changed "enable" to "enabled", and this changes it back.
Old users of "enable" are currently broken and will be helped by
this change. Anything that started to use "enabled" after v3.13
will be broken by this change. If necessary, we can add a symlink
to make both work, but this patch doesn't do that.
PCI device hotplug

A mistaken duplicate merge that added a check twice. Nothing's
broken; this just removes the unnecessary code.

Rusty noticed a Really Bad Bug (tm) in my NT fix. The entry code
reads out of bounds, causing the NT fix to be unreliable. But, and
this is much, much worse, if your stack is somehow just below the
top of the direct map (or a hole), you read out of bounds and crash.
Excerpt from the crash:
[ 1.129513] RSP: 0018:ffff88001da4bf88 EFLAGS: 00010296
2b:* f7 84 24 90 00 00 00 testl $0x4000,0x90(%rsp)
That read is deterministically above the top of the stack. I
thought I even single-stepped through this code when I wrote it to
check the offset, but I clearly screwed it up.

"A bit has accumulated, but it's been a week or so since my last batch
of post-merge-window fixes, so...
1) Missing module license in netfilter reject module, from Pablo.
Lots of people ran into this.
2) Off by one in mac80211 baserate calculation, from Karl Beldan.
3) Fix incorrect return value from ax88179_178a driver's set_mac_addr
op, which broke use of it with bonding. From Ian Morgan.
4) Checking of skb_gso_segment()'s return value was not all
encompassing, it can return an SKB pointer, a pointer error, or
NULL. Fix from Florian Westphal.
This is crummy, and longer term will be fixed to just return error
pointers or a real SKB.
6) Encapsulation offloads not being handled by
skb_gso_transport_seglen(). From Florian Westphal.
7) Fix deadlock in TIPC stack, from Ying Xue.
8) Fix performance regression from using rhashtable for netlink
sockets. The problem was the synchronize_net() invoked for every
socket destroy. From Thomas Graf.
9) Fix bug in eBPF verifier, and remove the strong dependency of BPF
on NET. From Alexei Starovoitov.
10) In qdisc_create(), use the correct interface to allocate
->cpu_bstats, otherwise the u64_stats_sync member isn't
initialized properly. From Sabrina Dubroca.
11) Off by one in ip_set_nfnl_get_byindex(), from Dan Carpenter.
12) nf_tables_newchain() was erroneously expecting error pointers from
netdev_alloc_pcpu_stats(). It only returna a valid pointer or
NULL. From Sabrina Dubroca.
13) Fix use-after-free in _decode_session6(), from Li RongQing.
14) When we set the TX flow hash on a socket, we mistakenly do so
before we've nailed down the final source port. Move the setting
deeper to fix this. From Sathya Perla.
15) NAPI budget accounting in amd-xgbe driver was counting descriptors
instead of full packets, fix from Thomas Lendacky.
16) Fix total_data_buflen calculation in hyperv driver, from Haiyang
Zhang.
17) Fix bcma driver build with OF_ADDRESS disabled, from Hauke
Mehrtens.
18) Fix mis-use of per-cpu memory in TCP md5 code. The problem is
that something that ends up being vmalloc memory can't be passed
to the crypto hash routines via scatter-gather lists. From Eric
Dumazet.
19) Fix regression in promiscuous mode enabling in cdc-ether, from
Olivier Blin.
20) Bucket eviction and frag entry killing can race with eachother,
causing an unlink of the object from the wrong list. Fix from
Nikolay Aleksandrov.
21) Missing initialization of spinlock in cxgb4 driver, from Anish
Bhatt.
22) Do not cache ipv4 routing failures, otherwise if the sysctl for
