Certain functions in xen_disk are called with a pointer to xendev (struct XenDevice *). They then use container_of() to acces the surrounding blkdev (struct XenBlkDev) but then in various places use &blkdev->xendev when use of the original xendev pointer is shorter to express and clearly equivalent. This patch is a purely cosmetic patch which makes sure there is a xendev pointer on stack for any function where the pointer is need on multiple occasions modified those functions to use it consistently.

This patch adds grant table helper functions to the xen_backend code to localize error reporting and use of xen_domid. The patch also defers the call to xengnttab_open() until just before the initialise method in XenDevOps is invoked. This method is responsible for mapping the shared ring. No prior method requires access to the grant table.

Currently the xen_disk source has to carry #ifdef exclusions to compile against Xen older then 4.8. This is a bit messy so this patch lifts the definition of struct xengnttab_grant_copy_segment and adds it into the pre-4.8 compat area in xen_common.h, which allows xen_disk to be cleaned up.

All the xen stable APIs define handle types of the form: xen<subject of API>_handle and some define additional handle types of the form: xen<subject of API>_<purpose of handle>_handle Examples of these are xenforeignmemory_handle and xenforeignmemory_resource_handle. Both of these types will be misparsed by checkpatch if they appear as the first token in a line since, as types defined by an external library, they do not conform to the QEMU CODING_STYLE, which suggests CamelCase. A previous patch (5ac067a2) added xendevicemodel_handle to the list of types. This patch changes that to xen\w+_handle such that it will match all Xen stable API handles of the forms detailed above.

"Some AMD processors only support a non-architectural means of enabling speculative store bypass disable (SSBD). To allow a simplified view of this to a guest, an architectural definition has been created through a new CPUID bit, 0x80000008_EBX[25], and a new MSR, 0xc001011f. With this, a hypervisor can virtualize the existence of this definition and provide an architectural method for using SSBD to a guest. Add the new CPUID feature, the new MSR and update the existing SSBD support to use this MSR when present." (from x86/speculation: Add virtualized speculative store bypass disable support in Linux).

After 1217d6ca we error out explicitly if an unknown -option was passed on the command line. However, we are doing two pass command line option parsing. In the first pass we just look for -no-user-config or -nodefconfig being present which determines whether we load user config or not. Then in the second pass we finally parse everything else throwing an error if an unsupported -option was found. Problem is that in the second pass -no-user-config and -nodefconfig are not handled explicitly which makes us throw the unsupported option error.
