* x86/entry: Use generic syscall exit functionalityThomas Gleixner2020-07-241-0/+44
| | | | | | | | | | | | | | Replace the x86 variant with the generic version. Provide the relevant architecture specific helper functions and defines. Use a temporary define for idtentry_exit_user which will be cleaned up seperately.

* x86/entry: Use generic syscall entry functionThomas Gleixner2020-07-241-0/+32
Replace the syscall entry work handling with the generic version. Provide the necessary helper inlines to handle the real architecture specific parts, e.g. ptrace. Use a temporary define for idtentry_enter_user which will be cleaned up seperately.
