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.

hv: fix 'User name starts with underscore' There are chances that names with leading underscore declared by developers are conflict with the ones reserved for the compiler. What this patch does: - rename these functions/variables/macros starting with underscore to avoid such unintentational mistakes. - remove gpr.h without any contents Tracked-On: #861 Signed-off-by: Shiqing Gao <shiqing.gao@intel.com> Acked-by: Eddie Dong <eddie.dong@intel.com>

HV:treewide:rename vcpu data structure For data structure types "struct vcpu", its name is identical with variable name in the same scope. This is a MISRA C violation. Naming convention rule:If the data structure type is used by multi modules, its corresponding logic resource is exposed to external components (such as SOS, UOS), and its name meaning is simplistic (such as vcpu, vm), its name needs prefix "acrn_". The following udpates are made: struct vcpu *vcpu-->struct acrn_vcpu *vcpu Tracked-On: #861 Signed-off-by: Xiangyang Wu <xiangyang.wu@linux.intel.com>
