Hi Kirill, Dave,
Do you think if it's a good idea if I post a new patch that combines
    e1b8ac3aae58 ("x86/tdx: Support vmalloc() for tdx_enc_status_changed()")
and
    your patch "[PATCH] x86/tdx: Fix crash on kexec"?
 
Or, maybe Dave can help combine the two patches into one?

Just wanted to make sure e1b8ac3aae58 won't get lost.

Thanks,
Dexuan
