syscalls.h: slightly reduce the jungles of macros

2013-03-05T20:36:40+00:00

a) teach __MAP(num, m, ) to take empty
list (with num being 0, of course)
b) fold types__... and args__... declaration and initialization into
SYSCALL_METADATA(num, ...), making their use conditional on num != 0.
That allows to use the SYSCALL_METADATA instead of its near-duplicate
in SYSCALL_DEFINE0.
c) make SYSCALL_METADATA expand to nothing in case if CONFIG_FTRACE_SYSCALLS
is not defined; that allows to make SYSCALL_DEFINE0 and SYSCALL_DEFINEx
definitions independent from CONFIG_FTRACE_SYSCALLS.
d) kill SYSCALL_DEFINE - no users left (SYSCALL_DEFINE[0-6] is, of course,
still alive and well).

get rid of union semop in sys_semctl(2) arguments

2013-03-05T20:14:16+00:00

just have the bugger take unsigned long and deal with SETVAL
case (when we use an int member in the union) explicitly.

make SYSCALL_DEFINE-generated wrappers do asmlinkage_protect

2013-03-04T03:58:33+00:00

... and switch i386 to HAVE_SYSCALL_WRAPPERS, killing open-coded
uses of asmlinkage_protect() in a bunch of syscalls.

consolidate cond_syscall and SYSCALL_ALIAS declarations

2013-03-04T03:55:19+00:00

take them to asm/linkage.h, with default in linux/linkage.h

teach SYSCALL_DEFINE how to deal with long long/unsigned long long

2013-03-04T03:46:22+00:00

... and convert a bunch of SYSCALL_DEFINE ones to SYSCALL_DEFINE,
killing the boilerplate crap around them.

get rid of duplicate logics in __SC_....[1-6] definitions

2013-03-04T03:46:21+00:00

All those guys have the same form - "take a list of type/name pairs,
apply some macro to each of them".  Abstract that part away, convert
all __SC_FOO##x(__VA_ARGS__) to __MAP(x,__SC_FOO,__VA_ARGS__).
