[UNIKRAFT PATCH v2 0/3] lib/syscall_shim: Enhancements

[Simon Kuenzer <simon.kuenzer@xxxxxxxxx>]

This patch series contains a couple of enhancments to lib/syscall_shim
API that are useful for porting applications to Unikraft.

Changes v2:
 - Avoid unused parameter warning of `arg` in `uk_vsyscall()` and
   `uk_vsyscall_r()`. The warning appears when no system calls are
   registered to the system call shim layer.

Simon Kuenzer (3):
  lib/syscall_shim: Provide `uk_syscall_r_fn()`
  lib/syscall_shim: handler: Take only required number of arguments
  lib/syscall_shim: Provide `uk_syscall6()`, `uk_syscall6_r()`
