ARM: at91: remove useless init_time for DT-only SoCs
Commits
bcf8c7e7703bb2bbde66bec26a81fed4be9cd1d4 and
4bf7753b8ab7c704ca864b1653367ea9cfe68a25 introduced compilation errors
("error: 'NR_IRQS_LEGACY' undeclared (first use in this function)") because
they remove the asm/irq.h inclusion while the init_time function needs it
for the NR_IRQS_LEGACY definition.
In the other hand, the point of these commits is to remove board file
support, and init_time is only needed when booting non-DT boards, we can
thus safely remove init_time functions.

Robert Richter:
dts, kbuild: Implement support for dtb vendor subdirs
For arm64 we want to put dts files into vendor's subdirectories from
the beginning. This patch set implements this. As this is a generic
kbuild implementation, vendor subdirs will be also available for
arch/arm and other architectures. The subdirectory tree is also
reflected in the install path.
A new makefile variable dts-dirs is introduced to point to dts
subdirs. This variable is used by kbuild for building and installation
of dtb files.
A dts Makefile looks now as follows:
----
dtb-$(CONFIG_...) += some_file_1.dtb
dtb-$(CONFIG_...) += some_file_2.dtb
dts-dirs += dir_vendor_a
dts-dirs += dir_vendor_b
always := $(dtb-y)
subdir-y := $(dts-dirs)
clean-files := *.dtb
----
This patches also introduces the dtbs_install make target for
arm64. Install rules are moved to Makefile.dtbinst using the same
style and calling convention like for modinst and fwinst.

framework, we omitted proper listing of the SPI device IDs. This
means m25p80.c wouldn't auto-load (modprobe) properly when built as

- 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.

KVM: nVMX: Disable preemption while reading from shadow VMCS
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.

incorrect evaluation, far jump to segment with L bit cleared (i.e., 32-bit

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
ACPI core causing ACPI enumeration to be applied to all devices
associated with one ACPI companion object, although it should be
used for one of them only (Mika Westerberg).

some Samsung laptops to misbehave as a result of a workaround
targeted at some Acer machines. That includes a revert of a commit
that went too far and a quirk for the Acer machines in question.
From Lv Zheng.
- Fix a regression in the system suspend error code path introduced
during the 3.15 cycle that causes it to fail to take errors from
asychronous execution of "late" suspend callbacks into account
(Imre Deak).
- Fix a long-standing bug in the hibernation resume error code path
that fails to roll back everything correcty on "freeze" callback
errors and leaves some devices in a "suspended" state causing more
breakage to happen subsequently (Imre Deak).
