c4c6e192ac pthread_exit should call __NR_exit with status 0.
We shouldn't have been passing the bottom 32 bits of the address used
for pthread_join to the kernel.

6fe4e87954 Add an optional alias list to SYSCALLS.TXT
This patch adds an optional alias list to SYSCALLS.TXT.  It is used to
create aliases for a syscall.  For x86-64, lseek64 is an alias for lseek.

72645164b6 Add arch-x86_64/include/machine.
This is basically the other half of I5de76f6c46ac87779f207d568a86bb453e2414de
from Pavel Chupin <pavel.v.chupin@intel.com>, but taking the exact upstream
_types.h instead of the modified version. (I was confused when I suggested
otherwise.)

I've also cleaned up the internal_types.h situation; we weren't gaining
anything from these empty files, and there is no upstream internal_types.h
for x86_64.

4906e5653c Add arch-x86_64/bionic.
This is basically half of I5de76f6c46ac87779f207d568a86bb453e2414de from
Pavel Chupin <pavel.v.chupin@intel.com>, but with the stock upstream
setjump/sigsetjmp and H.J. Lu's suggested changes to __rt_sigreturn.

a567a8e4bd x86_64: Update Makefiles for x86_64 targets and add symlinks
Use basic .c versions of all functions for x86_64 until they are
manually optimized and .s versions released.

9a4127bb0a x86_64: add new __NR_arch_prctl syscall
This is used to set/get TLS on x86_64. There's no public declaration
of this because it's not meant to be used outside the C library, like
glibc (though we don't currently have any visibility controls to ensure
this).

e4ffd9f234 Regenerate the system call stubs (to get x86_64).
This touches the x86 stubs too because arm, x86, and x86_64 now
all share the same header (at a source level), which causes a
reordering of the #include lines.
