Changing the folder structure will cause too many broken links for
external references (from other sites). So, let's put the content back
where it was before the reorg, and instead use the new persona-based
navigation to point to documents in the original locations.
Also, introduce redirects for some documents that no longer exits.

For non-trusty hypercalls, HV should inject #GP(0) to vCPU if they are
from non-ring0 or inject #UD if they are from ring0 of non-SOS. Also
we should not modify RAX of vCPU for these invalid vmcalls.

In current code, the timer_list for per cpu can be accessed both in
vmexit and softirq handler. There is a case that, the timer_list is
modifying in vmexit, but an interrupt occur, the timer_list is also
modified in softirq handler. So the time_list may in unpredictable
state. In some platforms, the hv console may hang as its timer handler
is not invoked because of the corruption for timer_list.
So, to fix the issue, disable the interrupt before modifying the
timer_list.

In some case, guest need to get more information under virtual environment,
like guest capabilities. Basically this could be done by hypercalls, but
hypercalls are designed for trusted VM/SOS VM, We need a machenism to report
these information for normal VMs. In this patch, vCPUID leaf 0x40000001 will
be used to satisfy this needs that report some extended information for guest

The policy of vART is that software in native can run in
VM too. And in native side, the relationship between the
ART hardware and TSC is:
pTSC = (pART * M) / N + pAdjust
The vART solution is:
- Present the ART capability to guest through CPUID leaf
15H for M/N which identical to the physical values.
- PT devices see the pART (vART = pART).
- Guest expect: vTSC = vART * M / N + vAdjust.
- VMCS.OFFSET = vTSC - pTSC = vAdjust - pAdjust.
So to support vART, we should do the following:
1. if vAdjust and vTSC are changed by guest, we should change
VMCS.OFFSET accordingly.
2. Make the assumption that the pAjust is never touched by ACRN.
For #1, commit "a958fea hv: emulate IA32_TSC_ADJUST MSR" has implementation
it. And for #2, acrn never touch pAdjust.
--
v2 -> v3:
- Add comment when handle guest TSC_ADJUST and TSC accessing.
- Initialize the VMCS.OFFSET = vAdjust - pAdjust.
v1 -> v2
Refine commit message to describe the whole vART solution.

specific cpu state table in board.c which could be auto-generated by offline
tool, then the CPU Px/Cx of customer board could be enabled;
Hypervisor will search the cpu state table in cpu_state_tbl[] first, if not
found then go check board_cpu_state_tbl. If no matched cpu state table is found
then Px/Cx will not be supported;

The caller function has already done the checking to make sure the req is targeted
for the called functions, so there is no need to do the same checking in called
functions.
Remove calling of is_bar_offset() in vdev_pt_read_cfg/vdev_pt_write_cfg:
In vpci.c's vpci_read_pt_dev_cfg and vpci_write_dev_cfg, vbar_access is called
first to make sure the req is targed for vdev pt (vbar emulation) before
dispatching the request to vdev_pt_read_cfg/vdev_pt_write_cfg, so there is no
need to call is_bar_offset() again to do the same checking in vdev_pt_read_cfg/vdev_pt_write_cfg.
The same goes for msicap_access/msixcap_access
vbar_access should only check if the req is for bar access, it should not care
about whether the bar access is 4 bytes or 4 bytes aligned. The called function
vdev_pt_write_vbar will check and ignore the write access if it is not 4 bytes or 4 bytes
aligned, although this is counted as a bar access.
vdev_pt_read_vbar will check if the read access is 4 bytes or 4 bytes
aligned, although this is counted as a bar access, set read value (*val) to
-1 if the access is not 4 bytes (or aligned).
