This patch set enables kdump (crash dump kernel) support on arm64 on top of
Geoff's kexec patchset.
In this version, there are some arm64-specific usage/constraints:
1) "mem=" boot parameter must be specified on crash dump kernel
if the system starts on uefi.
2) Kvm will not be enabled on crash

On system kernel, the memory region used by crash dump kernel must be
specified by "crashkernel=X@Y" boot parameter. reserve_crashkernel()
will allocate the region in "System RAM" and reserve it for later use.
On crash dump kernel, memory region information in system kernel is

kdump calls machine_crash_shutdown() to shut down non-boot cpus and
save per-cpu general-purpose registers before restarting the crash dump
kernel. See kernel_kexec().

Unlike normal kexec case, we don't have a chance to reset EL2 context in

Kvm is not useful on crash dump kernel anyway, and so we let it

Make sure that xen_swiotlb_init allocates buffers that are DMA capable
when at least one memblock is available below 4G. Otherwise we assume
that all devices on the SoC can cope with >4G addresses. We do this on
ARM and ARM64, where dom0 is mapped 1:1, so pfn == mfn in this case.

If a PVOPS VM has multi-cpu the vcpu_info of cpu0 is the member of the
structure HYPERVISOR_shared_info,
and the others is not, but after 'xl save -c/restore' the vcpu_info will be
reinitialized,
the vcpu_info of all the vcpus will be considered as the member of
HYPERVISOR_shared_info.

We need those to be visible even when compiling with CONFIG_OF
disabled, since even the empty of_node_*_flag() method use the
flag.

During the course of the overlay selftests some of them remain

them and destroy them at the end of the test.

We need this earlier in the boot process to allow various subsystems
to use configfs (e.g Industrial IIO).
Also, debugfs is at core_initcall level and configfs should be on
the same level from infrastructure point of view.

We are going to need the overlays to appear on sysfs with runtime
global properties (like master enable) so turn them into kobjects.

The first patch puts the overlays as objects in the sysfs in
/sys/firmware/devicetree/overlays.
The next adds a master overlay enable switch (that once is set to
disabled can't be re-enabled), while the one after that
introduces a number of default per overlay attributes.
The patchset is against
A throw once master enable switch to protect against any
further overlay applications if the administrator desires so.

This allows user to pass the filter pattern directly to
--funcs option as below.
# ./perf probe -F *kmalloc
__kmalloc
devm_kmalloc
mempool_kmalloc
sg_kmalloc
sock_kmalloc
We previously need --filter option for that.

Accept multiple filter options. Each filters are combined
