Last change on this file since 80487bc5 was 8e000b8d, checked in by Jakub Jermar <jakub@…>, 16 years ago

Rename syscall_{int,sysenter} to syscall_{slow,fast}. Syscalls that could be
potentially handled by the fast version make an indirect call using
syscall_fast_func function pointer so that libc has a chance to switch the
implementation. The default implementation is
syscall_slow.
