Tom Lendacky c08ba63078 virt: sev-guest: Satisfy linear mapping requirement in get_derived_key() ... Commit 7ffeb2fc26 ("x86/sev: Document requirement for linear mapping of guest request buffers") added a check that requires the guest request buffers to be in the linear mapping. The get_derived_key() function was passing a buffer that was allocated on the stack, resulting in the call to snp_send_guest_request() returning an error. Update the get_derived_key() function to use an allocated buffer instead of a stack buffer.
