From the release notes:

   Changes affecting future time stamps

     Pacific/Fiji will observe DST from 2014-11-02 02:00 to
     2015-01-18 03:00.  (Thanks to Ken Rylander for the heads-up.)
     Guess that future years will use a similar pattern.

     A new Zone Pacific/Bougainville, for the part of Papua New
     Guinea that plans to switch from UTC+10 to UTC+11 on
     2014-12-28 at 02:00.  (Thanks to Kiley Walbom for the
     heads-up.)

   Changes affecting time zone abbreviations

     Since Belarus is not changing its clocks even though Moscow
     is, the time zone abbreviation in Europe/Minsk is changing
     from FET to its more-traditional value MSK on 2014-10-26 at
     01:00.  (Thanks to Alexander Bokovoy for the heads-up about
     Belarus.)

     The new abbreviation IDT stands for the pre-1976 use of UT+8
     in Indochina, to distinguish it better from ICT (UT+7).

   Changes affecting past time stamps

     Many time stamps have been corrected for Asia/Ho_Chi_Minh
     before 1976 (thanks to Trần Ngọc Quân for an indirect pointer
     to Trần Tiến Bình's authoritative book).  Asia/Ho_Chi_Minh has
     been added to zone1970.tab, to give tzselect users in Vietnam
     two choices, since north and south Vietnam disagreed after our
     1970 cutoff.

     Asia/Phnom_Penh and Asia/Vientiane have been turned into
     links, as they differed from existing zones only for older
     time stamps.  As usual, these changes affect pre-1970 time
     stamps only.  Their old contents have been moved to the
     'backzone' file.

0724132c32 Fix race condition in timer disarm/delete.
When setting a repeat timer using the SIGEV_THREAD mechanism, it's possible
that the callback can be called after the timer is disarmed or deleted.
This happens because the kernel can generate signals that the timer thread
will continue to handle even after the timer is supposed to be off.

Add two new tests to verify that disarming/deleting doesn't continue to
call the callback.

Modify the repeat test to finish more quickly than before.

Refactor the Counter implementation a bit.

Christopher Ferris
f4ada9c9ce Return total footprint, not high water mark.
The mallinfo usmblks value returned by dlmalloc is a little misleading.
It's not the current max, it's the historical high water mark. This
leads to dumpsys meminfo producing native memory numbers that don't add up.
Change this to the real total footprint, not this high water mark.

2f25cf373c Fix pthread_attr_getstack under valgrind.
valgrind seems to mess with the stack enough that the kernel will
report "[stack:pid]" rather than "[stack]" in /proc/self/maps, so
switch to the task-specific file instead to force "[stack]". (There
are two conditions in the kernel code that decides which form to
output.)

55ee845b8e Inline helpers need to be exported unmangled.
__open_2() is used by the fortify implementation of open(2) in
fcntl.h, and as such needs an unmangled C name. For some reason
(inlining?), this doesn't cause problems at the default optimization
level, but does for -O0.

The rest of these didn't cause build failures, but they look suspect
and probably will, we just haven't caught them yet.

d87d401ab1 Improve <sys/cdefs.h>.
Fix and use __RENAME (and lose ___RENAME --- two underscores should be
enough for anybody). This was the point of this change, because I want
to use __RENAME to support the two basename variants and the two
strerror_r variants.

Lose a bunch of macros that weren't being used.

Lose three dead files from the DNS code.

d11eac3455 Force export symbols on all x86 variants in libc.
For silvermont, the __popcountsi2 symbol does not get exported by libc.
But for atom, this symbol is exported. Since we already exported this symbol
for previous releases, it's better to just follow through and force
the export, but only for 32 bit. x86 64 bit will not export this symbol.

Alex Van Brunt
a508714800 Reimplement clock(3) using clock_gettime(3)
Unlike times(), clock_gettime() is implemented as a vDSO on many architectures.
So, using clock_gettime() will return a more accurate time and do so with less
overhead because it does have the overhead of calling into the kernel.

It is also significantly more accurate because it measures the actual time in
nanoseconds rather than the number of ticks (typically 1 millisecond or more).

f4cb631364 Add IFUNC support for arm64 and IRELATIVE reloc
There are number of changes in the way IFUNC related relocations are done:
 1. IRELATIVE relocations are now supported for x86/x86_64 and arm64.
 2. IFUNC relocations are now relying on static linker to generate
    them in correct order - this removes necessety of additional
    relocation pass for ifuncs.
 3. Related to 2: rela?.dyn relocations are preformed before .plt ones.
 4. Ifunc are resolved on symbol lookup this approach allowed to avoid
    mprotect(PROT_WRITE) call on r-x program segments.

From the release notes:

  Changes affecting past time stamps

    America/Jamaica's 1974 spring-forward transition was Jan. 6, not Apr. 28.

    Shanks says Asia/Novokuznetsk switched from LMT (not "NMT") on 1924-05-01,
    not 1920-01-06.  The old entry was based on a misinterpretation of Shanks.

    Some more zones have been turned into links, when they differed
    from existing zones only for older time stamps.  As usual,
    these changes affect UTC offsets in pre-1970 time stamps only.
    Their old contents have been moved to the 'backzone' file.
    The affected zones are: Africa/Blantyre, Africa/Bujumbura,
    Africa/Gaborone, Africa/Harare, Africa/Kigali, Africa/Lubumbashi,
    Africa/Lusaka, Africa/Maseru, and Africa/Mbabane.

27efc48814 Add pthread_gettid_np and re-expose __get_thread for LP32.
A lot of third-party code calls the private __get_thread symbol,
often as part of a backport of bionic's pthread_rwlock implementation.
Hopefully this will go away for LP64 (since you're guaranteed the
real implementation there), but there are still APIs that take a tid
and no way to convert between a pthread_t and a tid. pthread_gettid_np
is a public API for that. To aid the transition, make __get_thread
available again for LP32.
