CHEN Gang de4b596e3a tools: acrn-crashlog: change source of config file
This patch is to change the source of config file according
to the doc of telemetrics-client:

There is a config file installed at
``/usr/share/defaults/telemetrics/telemetrics.conf``
To make modifications, copy that file to
``/etc/telemetrics/telemetrics.conf``
and modify the /etc version.

Otherwise, the modification may be lost after ``swupd update``.

soft-lock or CPUs stalls can happen during UOS running; after debugging,

root cause: PIO/MMIO from UOS will trigger SOS/DM to handle them. Usually,

Huihuang Shi e591315a65 HV:treewide:C99-friendly per_cpu implementation change the per_cpu method
The current implementation of per_cpu relies on several non-c99 features,
and in additional involves arbitrary pointer arithmetic which is not MIS-
RA C friendly.

This patch introduces struct per_cpu_region which holds all the per_cpu
variables. Allocation of per_cpu data regions and access to per_cpu vari-
ables are greatly simplified, at the cost of making all per_cpu varaibl-
es accessible in files.

Geoffroy Van Cutsem 7f2a7d47dd Tools Makefiles: enhancement to keep source code tree clean
Running 'make' will leave 3 files in the source code tree that
are not cleaned by a subsequent 'make clean'. These are:
* tools/acrn-crashlog/acrnprobe/include/version.h
* tools/acrn-crashlog/usercrash/include/version.h
* tools/acrn-manager/acrn_mngr.o
(as reported by 'git status' after 'make')

This patch changes the location of these files so they are
created in the target build directory and hence properly
cleaned when running 'make clean'

Other minor changes to the Makefiles include:
* Remove BASEDIR by the built-in CURDIR variable
* Add .PHONY targets

Li, Fei1 84f4cf3c1d hv: vmx: add vpid support
Enable VMX vpid ctrl and assign an unique vpid to each vcpu
so that VMX transitions are not required to invalidate any
linear mappings or combined mappings.

SDM Vol 3 - 28.3.3.3
If EPT is in use, the logical processor associates all mappings
it creates with the value of bits 51:12 of current EPTP.
If a VMM uses different EPTP values for different guests, it may
use the same VPID for those guests. Doing so cannot result in one
guest using translations that pertain to the other.

In our UOS, the trusty world and normal world are using different
EPTP. So we can use the same VPID for it.
