Hi Linus,
Please pull a single x86/tdx change for 6.4.
The original assembly here took two flags in %RSI to tweak its behavior
at runtime. PeterZ recently axed one flag. Kill the other and tweak
the 'output' mode with an assembly macro instead. This results in
elimination of one push/pop pair and overall easier to read assembly.
