[patch V4 part 4 19/24] x86/entry: Implement user mode C entry points for #DB and #MCE

The MCE entry point uses the same mechanism as the IST entry point for now. For #DB split the inner workings and just keep the ist_enter/exit magic in the IST variant. Fixup the ASM code to emit the proper noist_##cfunc call. Signed-off-by: Thomas Gleixner --- arch/x86/entry/entry_64.S |
