Include <machine/asm.h> instead of defining our own ENTRY() macro Changed all instances of ENTRY() to match the new calling convention (it takes a second argument ). Added new macros: SYSTRAP(x): Expands to the code used to call syscall x. This is used to simplify other macros. SYSCALL_NOERROR(x): Like SYSCALL except that "x" is a syscall that can never fail. RSYSCALL_NOERROR(x): Like RSYSCALL except that "x" is a syscall that can never fail.
