[PATCH 10/20] x86/tdx: Convert GET_QUOTE hypercall to use new TDVMCALL macros

[Kirill A. Shutemov]

Use newly introduced TDVMCALL_0() instead of __tdx_hypercall() to issue
GET_QUOTE hypercall.

It cuts code bloat substantially:

Function                                     old     new   delta
tdx_hcall_get_quote                          188      76    -112
