This file was added to sysdeps/generic/bits in 2012. This appears to
have been an oversight, as the entire sysdeps/generic/bits directory was
moved to the top level in 2005. Accordingly the generic bits/hwcap.h
belongs there too.
* sysdeps/generic/bits/hwcap.h: Moved to ...
* bits/hwcap.h: Here.
This avoids aliasing issues with GCC 6 in -fno-strict-aliasing
mode. (With implicit padding, not all data is copied.)
This change makes it explicit that struct sockaddr_storage is
only 126 bytes large on m68k (unlike elsewhere, where we end up
with the requested 128 bytes). The new test case makes sure that
this does not happen on other architectures.
RFC2292 macros were obsoleted by RFC3542, and should not be exposed
any more. Notably since IPV6_PKTINFO has been reintroduced with a
completely different API.
* bits/in.h (IPV6_PKTINFO): Rename to IPV6_2292PKTINFO.
(IPV6_HOPOPTS): Rename to IPV6_2292HOPOPTS.

The overloading approach in the W* macros was incompatible with
integer expressions of a type different from int. Applications
using union wait and these macros will have to migrate to the
POSIX-specified int status type.
This patch updates the glibc headers with the defines MADV_FREE,
IPV6_HDRINCL and EPOLLEXCLUSIVE that are added in Linux 4.5.

As discussed in
https://sourceware.org/ml/libc-alpha/2015-10/msg00403.html
the setting of _STRING_ARCH_unaligned currently controls the external
GLIBC ABI as well as selecting the use of unaligned accesses withing
GLIBC.
Since _STRING_ARCH_unaligned was recently changed for AArch64, this
would potentially break the ABI in GLIBC 2.23, so split the uses and add
_STRING_INLINE_unaligned to select the string ABI. This setting must be
fixed for each target, while _STRING_ARCH_unaligned may be changed from
release to release. _STRING_ARCH_unaligned is used unconditionally in
glibc. But <bits/string.h>, which defines _STRING_ARCH_unaligned, isn't
included with -Os. Since _STRING_ARCH_unaligned is internal to glibc and
may change between glibc releases, it should be made private to glibc.
_STRING_ARCH_unaligned should defined in the new string_private.h heade
file which is included unconditionally from internal <string.h> for glibc
build.

This patch adds some new header definitions from Linux 4.4:
* MCL_ONFAULT is added to bits/mman.h / bits/mman-linux.h (this was
already done for hppa).
* PTRACE_SECCOMP_GET_FILTER is added to sys/ptrace.h. Along with it,
the older PTRACE_GETSIGMASK and PTRACE_SETSIGMASK, added in Linux
3.11 but missed at the time, are also added.

It was noted in
<https://sourceware.org/ml/libc-alpha/2012-09/msg00305.html> that the
bits/*.h naming scheme should only be used for installed headers.
This patch renames bits/atomic.h to atomic-machine.h to follow that
convention.
This is the only change in this series that needs to change the
filename rather than simply removing a directory level (because both
atomic.h and bits/atomic.h exist at present).
Tested for x86_64 (testsuite, and that installed stripped shared

This patch cleans up cases of __USE_MISC that are trivially redundant
after the recent substitution of __USE_MISC for __USE_BSD and
__USE_SVID: either in constructs such as "defined __USE_MISC ||
defined __USE_MISC", or else (in the bits/mman.h case) a conditional
on __USE_MISC nested inside another __USE_MISC conditional. (The
cleanups remaining after this patch are still quite large, but it
seems a reasonable piece to separate out.)
