Kirill A. Shutemov 1e70c68037 x86/tdx: Do not corrupt frame-pointer in __tdx_hypercall() ... If compiled with CONFIG_FRAME_POINTER=y, objtool is not happy that __tdx_hypercall() messes up RBP: objtool: __tdx_hypercall+0x7f: return with modified stack frame Rework the function to store TDX_HCALL_ flags on stack instead of RBP.
