Xenheap pages will always have an extra typecount, taken in share_xen_page_with_guest(), which doesn''t come from a shadow PTE. Adjust the warning in sh_remove_all_mappings() to account for it.

However I could observe VCPUs getting stuck in the trampoline after the following patch in the Linux kernel changed the way CR4 gets set up: x86, realmode: read cr4 and EFER from kernel for 64-bit trampoline The change will set CR4 from already set flags which includes the SMEP bit. On bare metal this does not matter as the CPU is in non- paging mode at that time. But Xen seems to use the emulated non- paging mode regardless of HAP (I verified that on the guests I was seeing the issue, HAP was not used). Therefor it seems right to unset the SMEP bit for a VCPU that is not in paging-mode, regardless of its HAP usage.
