11952073af Remove dependencies on obsolete __ARCH_WANT_SYSCALL_DEPRECATED system calls.
(aarch64 kernels don't have these system calls.)

cac7b9d6ec Remove dependencies on obsolete __ARCH_WANT_SYSCALL_NO_FLAGS syscalls.
(aarch64 kernels only have the newer system calls.)

Also expose the new functionality that's exposed by glibc in our header files.

f8fcfbc85a Move away from the __ARCH_WANT_SYSCALL_NO_AT system calls.
Modern architectures only get the *at(2) system calls. For example,
aarch64 doesn't have open(2), and expects userspace to use openat(2)
instead.

938f38daee Fix clone.S for x86_64.
We need to pull the arguments off the child stack and put them into the
registers they're expected to be in.

19e62325c2 Clean up the sigprocmask/pthread_sigmask implementation.
Let's have both use rt_sigprocmask, like in glibc. The 64-bit ABIs
can share the same code as the 32-bit ABIs.

Also, let's test the return side of these calls, not just the
setting.

2a0b873065 Fix __errno for LP64 and clean up __get_tls.
If __get_tls has the right type, a lot of confusing casting can disappear.

It was probably a mistake that __get_tls was exposed as a function for mips
and x86 (but not arm), so let's (a) ensure that the __get_tls function
always matches the macro, (b) that we have the function for arm too, and
(c) that we don't have the function for any 64-bit architecture.

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.

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.
