011e111d299284b65af07add523a9dccac356244 09-Sep-2014 Elliott Hughes <enh@google.com> Ensure __set_errno is still visible on LP32.

The use of the .hidden directive to avoid going via the PLT for
__set_errno had the side-effect of actually making __set_errno
hidden (which is odd because assembler directives don't usually
affect symbols defined in a different file --- you can't even
create a weak reference to a symbol that's defined in a different
file).

This change switches the system call stubs over to a new always-hidden
__set_errno_internal and has a visible __set_errno on LP32 just for
binary compatibility with old NDK apps.

(cherry-pick of 7efad83d430f4d824f2aaa75edea5106f6ff8aae.)

These calls were not going through the PLT like they should have been.

15a0456d0b7618554ed3d49287e77b6d43a2812a 06-Jun-2014 Elliott Hughes <enh@google.com> Remove unnecessary instructions from x86/x86_64 syscalls.

__set_errno returns -1 exactly so that callers don't need to bother.
The other architectures were already taking advantage of this, but
no one had ever fixed x86 and x86_64.

ed74484dcbc2e156a6e5fa861a62425b12e55128 07-Nov-2013 Elliott Hughes <enh@google.com> Stop using the non-uapi <linux/err.h> header file.

We only need it for MAX_ERRNO, and it's time we had somewhere to put
the little assembler utility macros we've been putting off writing.

No non-comment changes to the .S files.

e4ffd9f2341f42c9281b4a93df76768580535edd 01-Oct-2013 Elliott Hughes <enh@google.com> 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.
