Other architectures commonly use __NR_umount2 for sys_umount, only ia64 and alpha use __NR_umount here. In order to synchronize the generated tables, use umount2 like everyone else, and add back the old name from asm/unistd.h for compatibility. For shmat, alpha uses the osf_shmat name, we can do the same thing here, which means we don't have to add an entry in the __IGNORE list now that shmat is mandatory everywhere alarm, creat, pause, time, and utime are optional everywhere these days, no need to list them here any more. I considered also adding the regular versions of the get*id system calls that have different names and calling conventions on alpha, which would further help unify the syscall ABI, but for now I decided against that.
