| |
hi,
This series adds definitions for NR_syscalls for x86 and x86_64 and converts syscall events tracing to use NR_syscalls instead of FTRACE_SYSCALL_MAX. Note, the x86_64 NR_syscalls is defined in terms of __NR_syscall_max, and thus is dynamic (we don't need to update it when new syscalls are added). However, the x86 implementation adds a static define in unistd.h, at least for now.
Patches are against the current -tip tree. So the x86 static define will need to be updated with a patch when integrated in the -next tree (which has additional syscalls). Also, Paul Mundt has said he will update sh architecture (to remove the FTRACE_SYSCALL_MAX definition).
thanks,
-Jason
