8b756d40a7 Update syscall.master to 4.10-rc6. Also fix comments, a typo, 
and wrong numbering for a few unimplemented syscalls.

For 32-bit Linuxulator, socketcall() syscall was historically
the entry point for the sockets API. Starting in Linux 4.3, direct
syscalls are provided for the sockets API. Enable it.

The initial version of patch was provided by trasz@ and extended by me.

7672ca059a Remove unneeded includes of opt_kdtrace.h. 
As of r258541, KDTRACE_HOOKS is defined in opt_global.h, so opt_kdtrace.h
is not needed when defining SDT(9) probes.

e16fe1c730 Implement epoll family system calls. This is a tiny wrapper 
around kqueue() to implement epoll subset of functionality.
The kqueue user data are 32bit on i386 which is not enough for
epoll user data, so we keep user data in the proc emuldata.

Initial patch developed by rdivacky@ in 2007, then extended
by Yuri Victorovich @ r255672 and finished by me
in collaboration with mjg@ and jillies@.
