arch: sembuf.h: make uapi asm/sembuf.h self-contained
Userspace cannot compile <asm/sembuf.h> due to some missing type definitions. For example, building it for x86 fails as follows: CC usr/include/asm/sembuf.h.s In file included from <command-line>:32:0: usr/include/asm/sembuf.h:17:20: error: field `sem_perm' has incomplete type struct ipc64_perm sem_perm; /* permissions .. see ipc.h */ ^~~~~~~~ usr/include/asm/sembuf.h:24:2: error: unknown type name `__kernel_time_t' __kernel_time_t sem_otime; /* last semop time */ ^~~~~~~~~~~~~~~ usr/include/asm/sembuf.h:25:2: error: unknown type name `__kernel_ulong_t' __kernel_ulong_t __unused1; ^~~~~~~~~~~~~~~~ usr/include/asm/sembuf.h:26:2: error: unknown type name `__kernel_time_t' __kernel_time_t sem_ctime; /* last change time */ ^~~~~~~~~~~~~~~ usr/include/asm/sembuf.h:27:2: error: unknown type name `__kernel_ulong_t' __kernel_ulong_t __unused2; ^~~~~~~~~~~~~~~~ usr/include/asm/sembuf.h:29:2: error: unknown type name `__kernel_ulong_t' __kernel_ulong_t sem_nsems; /* no. of semaphores in array */ ^~~~~~~~~~~~~~~~ usr/include/asm/sembuf.h:30:2: error: unknown type name `__kernel_ulong_t' __kernel_ulong_t __unused3; ^~~~~~~~~~~~~~~~ usr/include/asm/sembuf.h:31:2: error: unknown type name `__kernel_ulong_t' __kernel_ulong_t __unused4; ^~~~~~~~~~~~~~~~ It is just a matter of missing include directive. Include <asm/ipcbuf.h> to make it self-contained, and add it to the compile-test coverage.
