Add TDX_BUG_ON() macros (with varying numbers of arguments) to deduplicate the myriad flows that do KVM_BUG_ON()/WARN_ON_ONCE() followed by a call to pr_tdx_error(). In addition to reducing boilerplate copy+paste code, this also helps ensure that KVM provides consistent handling of SEAMCALL errors. Opportunistically convert a handful of bare WARN_ON_ONCE() paths to the equivalent of KVM_BUG_ON(), i.e. have them terminate the VM. If a SEAMCALL error is fatal enough to WARN on, it's fatal enough to terminate the TD. Reviewed-by: Rick Edgecombe <[email protected]> Signed-off-by: Sean Christopherson <[email protected]>
