- Thread-topic: [RESEND PATCH v2 0/3] x86/hvm: vmx: refactor cache disable mode code
From: Grygorii Strashko <grygorii_strashko@xxxxxxxx>
The cache disable mode code (hvm_shadow_handle_cd()) is relevant only for Intel
VT-x (VMX),
hence:
- move hvm_shadow_handle_cd()/ hvm_set_uc_mode()/domain_exit_uc_mode() in VMX
code
- account for SHADOW_PAGING when use hvm_shadow_handle_cd()
- move cache disable mode data into VMX specific structures
Based on discussion [1].

x86/hvm: move hvm_shadow_handle_cd() to vmx code
x86/hvm: vmx: account for SHADOW_PAGING when use
hvm_shadow_handle_cd()
x86/hvm: vmx: refactor cache disable mode data
