516ab87ab9 Copyrights: fujitsu 2018 bump
Separate copyright bumps in a different commit.
A lot of files only had the copyright change at this point; these
were probably changes I added separatly in other patches but just
split these in a different commit instead to simplify git stats

342a2e1287 x86 syscalls: add a bunch of XXat() delegated syscalls
at least funlinkat is needed because these macros define __NR_x for mckernel
side and we will use funlinkat in a later commit

04c11f35e9 xpmem: Add xpmem_openat
In arm64, glibc-open of /dev/xpmem is hooked in sys_openat. This
commit adds xpmem_openat which is called by sys_openat.
This commit silently applies copy_from_user fix to sys_open as well.

3e3ccf377c compiler.h: add READ_ONCE/WRITE_ONCE macro
These macros are needed to make sure the compiler does not optimize away
atomic constructs such as "while (!READ_ONCE(foo))" loops that do not
modify foo within the loop

Also move the barrier() define where it belongs while we are here, it is
needed for READ_ONCE/WRITE_ONCE and including ihk/cpu.h here causes
include loops

e42c414454 uti: Hook system calls by binary-patching glibc
(1) Add --enable-uti option. The binary-patch library is
    preloaded with this option.
(2) Binary-patching is done by syscall_intercept developed by Intel

This commit includes the following fixes:

(1) Fix do_exit() and terminate() handling
(2) Fix timing of killing mcexec threads when McKernel thread calls terminate()
