thanks to the original factorization using the __timedwait function, there are no FUTEX_WAIT calls anywhere else, giving us a single point of change to make nearly all the timed thread primitives time64-ready. the one exception is the FUTEX_LOCK_PI command for PI mutex timedlock. I haven't tried to make these two points share code, since they have different fallbacks (no non-private fallback needed for PI since PI was added later) and FUTEX_LOCK_PI isn't a cancellation point (thus allowing the whole code path to inline into pthread_mutex_timedlock). as for other changes in this series, the time64 syscall is used only if it's the only one defined for the arch, or if the requested timeout does not fit in 32 bits. on current 32-bit archs where time_t is a 32-bit type, this makes it statically unreachable. on 64-bit archs, there are only superficial changes to the code after preprocessing. on current 32-bit archs, the time is passed via an intermediate copy to remove the assumption that time_t is a 32-bit type. |

musl libc
musl, pronounced like the word "mussel", is an MIT-licensed
implementation of the standard C library targetting the Linux syscall
API, suitable for use in a wide range of deployment environments. musl
offers efficient static and dynamic linking support, lightweight code
and low runtime overhead, strong fail-safe guarantees under correct
usage, and correctness in the sense of standards conformance and
safety. musl is built on the principle that these goals are best
achieved through simple code that is easy to understand and maintain.
The 1.1 release series for musl features coverage for all interfaces
defined in ISO C99 and POSIX 2008 base, along with a number of
non-standardized interfaces for compatibility with Linux, BSD, and
glibc functionality.
For basic installation instructions, see the included INSTALL file.
Information on full musl-targeted compiler toolchains, system
bootstrapping, and Linux distributions built on musl can be found on
the project website:
