Finished lcd_vmx_init and its dependencies.
Added a few missing macros to arch/x86/include/vmx.h, and RESERVED masks for easily determining which bits in a vmx control are reserved (needed in adjust_vmx_controls). Re-factored setup_vmcs_config and adjust_vmx_controls. setup_vmcs_config does pretty much the same thing, but it fails immediately if a control isn't available -- adjust_vmx_controls confirms that the exact desired controls are available, and sets the reserved bits to 1 or 0 as needed. Cleaner comments and organization. Re-factored the vmx basic settings to vmcs_config_basic_settings. Removed some of the vmx feature check code that was in the original lcd_vmx_init, as setup_vmcs_config now does that. Essentially a straight copy over of: -- __vmx_enable -- vmx_enable -- vmx_disable -- vmx_free_vmxon_areas -- __vmxon -- __vmxoff The only difference is I shifted tbl and cache invalidation to vmx_enable (originally in __vmx_enable) and added some comments. Straight copy over of -- vmx_alloc_vmcs -- vmx_free_vmcs -- invvpid, invept code, with slight renaming
