Yin Fengwei 4073b37369 hv: microcode: Enable microcode update from SOS.
microcode update from UOS is disabled.
microcode version checking is available for both SOS and UOS.

There are two TODOs of this patch:
1. This patch only update the uCode on pCPUs SOS owned. For the
   pCPUs not owned by SOS, the uCode is not updated. To handle
   this gap, we will have SOS own all pCPUs at boot time. So
   all pCPUs could have uCode updated. This will be handled
   in the patch to enable SOS own all pCPUs at boot time.

2. gva2gpa now doesn't check possible page table walk failure.
   Will add the failure check in gva2gpa in different patch.

Jason Chen CJ fcb95d02d6 uefi: init vlapic according to native lapic
this patch save native lapic configuration and restore it to vm0's vlapic
before its running, then doing hpet timer interrupt injection through vlapic

timer interrupt coming continuously.

Jason Chen CJ a87757d602 uefi: remove old interrupt injection method
we added uefi stub for hv, and want vm0 continue running under uefi env to
boot other uefi payload (osloader or bzImage).

during this, the uefi timer irq need be handled elegantly.

there are 3 types for uefi timer:
1. 8254 based on IRQ0 of PIC
2. HPET based on IOAPIC
3. HPET based on MSI

currently, we only support type 3 (HPET+MSI). But we are following a
in-correct flow to handle this timer interrupt:
- we set VMX_ENTRY_INT_INFO_FIELD directly if a timer interrupt happened
  before vcpu launching, this will make its vlapic mess up, which finally
  cause hpet timer stop.

this patch remove this in-correct approach, the new approach patch will
be followed by next patch.

Zheng, Gen 124910ba14 vm load: fix bug in loading kernel
According to the explaination for pref_address
in Documentation/x86/boot.txt, a relocating bootloader
should attempt to load kernel at pref_address if possible.
But due to a non-relocatable kernel will unconditionally
move itself and to run at perf address, no need to copy
kernel to perf_address by bootloader.

entries are copied form normal world,the PML4/PDPT for secure
world are separated from Normal World, PD/PT are shared in the
Secure World's EPT and Normal World's EPT.Secure world can
