*	fix race condition in pthread_kill	Rich Felker	2011-06-14	1	-1/+5
\| \| \| \| \| \| \| \| \| \| \| \| \| \|	if thread id was reused by the kernel between the time pthread_kill read it from the userspace pthread_t object and the time of the tgkill syscall, a signal could be sent to the wrong thread. the tgkill syscall was supposed to prevent this race (versus the old tkill syscall) but it can't; it can only help in the case where the tid is reused in a different process, but not when the tid is reused in the same process. the only solution i can see is an extra lock to prevent threads from exiting while another thread is trying to pthread_kill them. it should be very very cheap in the non-contended case.
*	consistency: change all remaining syscalls to use SYS_ rather than __NR_ prefix	Rich Felker	2011-04-06	1	-1/+1

*	syscall overhaul part two - unify public and internal syscall interface	Rich Felker	2011-03-19	1	-2/+1
\| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \|	with this patch, the syscallN() functions are no longer needed; a variadic syscall() macro allows syscalls with anywhere from 0 to 6 arguments to be made with a single macro name. also, manually casting each non-integer argument with (long) is no longer necessary; the casts are hidden in the macros. some source files which depended on being able to define the old macro SYSCALL_RETURNS_ERRNO have been modified to directly use __syscall() instead of syscall(). references to SYSCALL_SIGSET_SIZE and SYSCALL_LL have also been changed. x86_64 has not been tested, and may need a follow-up commit to fix any minor bugs/oversights.
