d6bf56db0c42e3 Thomas Gleixner 2020-02-25 35 * Declares three functions:
d6bf56db0c42e3 Thomas Gleixner 2020-02-25 36 * - The ASM entry point: asm_##func
d6bf56db0c42e3 Thomas Gleixner 2020-02-25 37 * - The XEN PV trap entry point: xen_##func (maybe unused)
d6bf56db0c42e3 Thomas Gleixner 2020-02-25 38 * - The C handler called from the ASM entry point
d6bf56db0c42e3 Thomas Gleixner 2020-02-25 39 *
d6bf56db0c42e3 Thomas Gleixner 2020-02-25 40 * Note: This is the C variant of DECLARE_IDTENTRY(). As the name says it
d6bf56db0c42e3 Thomas Gleixner 2020-02-25 41 * declares the entry points for usage in C code. There is an ASM variant
d6bf56db0c42e3 Thomas Gleixner 2020-02-25 42 * as well which is used to emit the entry stubs in entry_32/64.S.
