-Subject: drop lazy plural forms init in dcngettext
-
-there is no good reason to wait to find and process the plural rules
-for a translated message file until a gettext form requesting plural
-rule processing is used. it just imposes additional synchronization,
-here in the form of clunky use of atomics.
-
-it looks like there may also have been a race condition where nplurals
-could be seen without plural_rule being seen, possibly leading to null
-pointer dereference. if so, this commit fixes it.

-Subject: support setting of default thread stack size via PT_GNU_STACK header
-
-this facilitates building software that assumes a large default stack
-size without any patching to call pthread_setattr_default_np or
-pthread_attr_setstacksize at each thread creation site, using just
-LDFLAGS.
-
-normally the PT_GNU_STACK header is used only to reflect whether
-executable stack is desired, but with GNU ld at least, passing
--Wl,-z,stack-size=N will set a size on the program header. with this
-patch, that size will be incorporated into the default stack size
-(subject to increase-only rule and DEFAULT_STACK_MAX limit).
-
-both static and dynamic linking honor the program header. for dynamic
-linking, all libraries loaded at program start, including preloaded
-ones, are considered. dlopened libraries are not considered, for
-several reasons. extra logic would be needed to defer processing until
-the load of the new library is commited, synchronization woud be
-needed since other threads may be running concurrently, and the
-effectiveness woud be limited since the larger size would not apply to
-threads that already existed at the time of dlopen. programs that will
-dlopen code expecting a large stack need to declare the requirement
-themselves, or pthread_setattr_default_np can be used.

-Subject: fix race condition in file locking
-
-The condition occurs when
-- thread #1 is holding the lock
-- thread #2 is waiting for it on __futexwait
-- thread #1 is about to release the lock and performs a_swap
-- thread #3 enters the __lockfile function and manages to grab the lock
- before thread #1 calls __wake, resetting the MAYBE_WAITERS flag
-- thread #1 calls __wake
-- thread #2 wakes up but goes again to __futexwait as the lock is
- held by thread #3
-- thread #3 releases the lock but does not call __wake as the
- MAYBE_WAITERS flag is not set
-
-This condition results in thread #2 not being woken up. This patch fixes
-the problem by making the woken up thread ensure that the flag is
-properly set before going to sleep again.
-
-Mainainer's note: This fixes a regression introduced in commit
-c21f750727515602a9e84f2a190ee8a0a2aeb2a1.

-Subject: fix getaddrinfo regression with AI_ADDRCONFIG on some configurations
-
-despite not being documented to do so in the standard or Linux
-documentation, attempts to udp connect to 127.0.0.1 or ::1 generate
-EADDRNOTAVAIL when the loopback device is not configured and there is
-no default route for IPv6. this caused getaddrinfo with AI_ADDRCONFIG
-to fail with EAI_SYSTEM and EADDRNOTAVAIL on some no-IPv6
-configurations, rather than the intended behavior of detecting IPv6 as
-unsuppported and producing IPv4-only results.
-
-previously, only EAFNOSUPPORT was treated as unavailability of the
-address family being probed. instead, treat all errors related to
-inability to get an address or route as conclusive that the family
-being probed is unsupported, and only fail with EAI_SYSTEM on other
-errors.
-
-further improvements may be desirable, such as reporting EAI_AGAIN
-instead of EAI_SYSTEM for errors which are expected to be transient,
-but this patch should suffice to fix the serious regression.

-Subject: fix broken atomic store on powerpc[64]
-
-in our memory model, all atomics are supposed to be full barriers;
-stores are not release-only. this is important because store is used
-as an unlock operation in places where it needs to acquire the waiter
-count to determine if a futex wake is needed. at least in the
-malloc-internal locks, but possibly elsewhere, soft deadlocks from
-missing futex wake (breakable by poking the threads to restart the
-syscall, e.g. by attaching a tracer) were reported to occur.
-
-once the malloc lock is replaced with Jens Gustedt's new lock
-implementation (see commit 47d0bcd4762f223364e5b58d5a381aaa0cbd7c38),
-malloc will not be affected by the issue, but it's not clear that
-other uses won't be. reducing the strength of the ordering properties
-required from a_store would require a thorough analysis of how it's
-used.
-
-to fix the problem, I'm removing the powerpc[64]-specific a_store
-definition; now, the top-level atomic.h will implement a_store using
-a_barrier on both sides of the store.
-
-it's not clear to me yet whether there might be issues with the other
-atomics. it's possible that a_post_llsc needs to be replaced with a
-full barrier to guarantee the formal semanics we want, but either way
-I think the difference is unlikely to impact the way we use them.
