- Make sure single object builds in arch/x86/virt/ ala

Browse source 
make ... arch/x86/virt/vmx/tdx/seamcall.o
   work again
 
 - Do not do ROM range scans and memory validation when the kernel is
   running as a SEV-SNP guest as those can get problematic and, before
   that, are not really needed in such a guest
 
 - Exclude the build-time generated vdso-image-x32.o object from objtool
   validation and in particular the return sites in there due to
   a warning which fires when an unpatched return thunk is being used
 
 - Improve the NMI CPUs stall message to show additional information
   about the state of each CPU wrt the NMI handler
 
 - Enable gcc named address spaces support only on !KCSAN configs due to
   compiler options incompatibility
 
 - Revert a change which was trying to use GB pages for mapping regions
   only when the regions would be large enough but that change lead to
   kexec failing
 
 - A documentation fixlet
