2021-02-15	sys/membarrier.h: add new constants from linux v5.10	Szabolcs Nagy	-0/+4
	can cause rseq restart on another cpu to synchronize with global memory access from rseq critical sections, see linux commit 2a36ab717e8fe678d98f81c14a0b124712719840 rseq/membarrier: Add MEMBARRIER_CMD_PRIVATE_EXPEDITED_RSEQ
2019-02-22	add membarrier syscall wrapper, refactor dynamic tls install to use it	Rich Felker	-0/+17
	the motivation for this change is twofold. first, it gets the fallback logic out of the dynamic linker, improving code readability and organization. second, it provides application code that wants to use the membarrier syscall, which depends on preregistration of intent before the process becomes multithreaded unless unbounded latency is acceptable, with a symbol that, when linked, ensures that this registration happens.
