Since Linux 3.11, O_TMPFILE allows to create unnamed files that can be
linked later on. It is internally defined as (O_TMPFILE | O_DIRECTORY)
to make it fail on old kernels.
Copying definitions from glibc for O_TMPFILE is not enough to support
O_TMPFILE; The open() wrapper also need to pass the mode when the flag
contains O_TMPFILE, otherwise, it will pass mode 000 which will succeed
but yield unexpected results.
openat() is curiously not affected since it passes the mode
unconditionally..

Rename various spare fields in structs to include a namespace
This should avoid accidental clashes with uses of the __unused symbol
in upstream projects. eg currently it causes a compile error in dhcpcd 8.x
due to their re-use of the __unused symbol as a macro
This follows the style of glibc which does something equivalent

If you enable these wrappers, be sure you don't need long double
precision on your embedded device, as these only enables
long double warpper functions to the existing double math
functions. Required to build some software as lvm2.

elf-fdpic.h or elf-dsbt.h is included by link.h. When C++ program
includes <link.h>, we get following build failure.
../usr/include/bits/elf-fdpic.h: In function 'void* __reloc_pointer(void*, const elf32_fdpic_loadmap*)':
../usr/include/bits/elf-fdpic.h:95: error: invalid use of 'void'
void pointer addition and subtraction is not allowed in C++ as it has
undetermined size, however in C with language extension it is possible
because sizeof void is treated as one byte.
Instead of performing subtraction on void pointers, typecast it to char*
first.
This build failure is detected by Buildroot autobuilder.

Only alpha, hppa and sparc need non-default value.

.globl can be used for every architecture so remove the define.
Sync with GNU C library.

It's even no longer required for non-ported ppc64
architecture. Sync with GNU C library.
This simplify the macros in include/libc-symbols.h.

The reason truncate64 takes 4 args on some arches is that their ABI
requires 64bit values to be aligned on register pair boundaries.
Since this alignment affects more than just truncate64, rename the
define to properly document its purpose. This also allows us to
expand it to the other impacted syscalls (which will be done in a
follow up commit).

Linux 3.4 added __kernel_long_t and __kernel_ulong_t and various
exported header files were updated to use these new types. Add the
definitions for __kernel_long_t and __kernel_ulong_t to the relevant
kernel_types.h headers.
This change was automated with the following scriptlet
git grep --name-only 'typedef.*__kernel_old_dev_t' \
| xargs sed -i '/typedef.*__kernel_old_dev_t/ a\
typedef long\t\t__kernel_long_t;\
typedef unsigned long\t__kernel_ulong_t;'
Whitespace in arm, avr32, hppa, sparc was then manually fixed up.

Here's a cleaned up patch which should get the whitespace right. I'm a
bit iffy about the sparc changes they make sense to me but it's not a
platform I have access to.
I can break this up per arch or per maintainer if requested.
