2009-09-23asm-generic: syscall_get_nr returns intRoland McGrath
Only 32 bits of system call number are meaningful, so make the specification for syscall_get_nr() be to return int, not long. Signed-off-by: Roland McGrath <roland@redhat.com>

2008-07-26tracehook: asm/syscall.hRoland McGrath
This adds asm-generic/syscall.h, which documents what a real asm-ARCH/syscall.h file should define. This is not used yet, but will provide all the machine-dependent details of examining a user system call about to begin, in progress, or just ended. Each arch should add an asm-ARCH/syscall.h that defines all the entry points documented in asm-generic/syscall.h, as short inlines if possible. This lets us write new tracing code that understands user system call registers, without any new arch-specific work.
