sh: remove nargs from __SYSCALL

2019-03-06T05:07:13+00:00

The __SYSCALL macro's arguments are system call number, system call
entry name and number of arguments for the system call.

Argument- nargs in __SYSCALL(nr, entry, nargs) is neither calculated nor
used anywhere.  So it would be better to keep the implementation as
__SYSCALL(nr, entry).  This unifies the implementation with some other
architectures too.

sh: generate uapi header and syscall table header files

2018-12-19T16:54:40+00:00

System call table generation script must be run to gener-
ate unistd_32.h and syscall_table.h files. This patch will
have changes which will invokes the script.

This patch will generate unistd_32.h and syscall_table.h
files by the syscall table generation script invoked by
sh/Makefile and the generated files against the removed
files must be identical.

The generated uapi header file will be included in uapi/-
asm/unistd.h and generated system call table header file
will be included by kernel/syscall_32.S file.

sh: Avoid exporting unimplemented syscalls.

2012-03-28T07:20:20+00:00

Now that userspace is making use of kernel-provided sanitized headers for
working out supported interfaces, we need to be a bit more diligent with
matching the syscall definitions with their actual wiring/support state.

In theory it shouldn't hurt anything since sys_ni_syscall will ultimately
do the right thing, but there's also not much need to lie about legacy
x86 syscalls that we've never supported.

This tightens things up a bit for uClibc at least.

All Arch: remove linkage for sys_nfsservctl system call

2011-08-26T22:09:58+00:00

The nfsservctl system call is now gone, so we should remove all
linkage for it.

ns: Wire up the setns system call

2011-05-28T17:48:39+00:00

32bit and 64bit on x86 are tested and working.  The rest I have looked
at closely and I can't find any problems.

setns is an easy system call to wire up.  It just takes two ints so I
don't expect any weird architecture porting problems.

While doing this I have noticed that we have some architectures that are
very slow to get new system calls.  cris seems to be the slowest where
the last system calls wired up were preadv and pwritev.  avr32 is weird
in that recvmmsg was wired up but never declared in unistd.h.  frv is
behind with perf_event_open being the last syscall wired up.  On h8300
the last system call wired up was epoll_wait.  On m32r the last system
call wired up was fallocate.  mn10300 has recvmmsg as the last system
call wired up.  The rest seem to at least have syncfs wired up which was
new in the 2.6.39.

v2: Most of the architecture support added by Daniel Lezcano 
v3: ported to v2.6.36-rc4 by: Eric W. Biederman 
v4: Moved wiring up of the system call to another patch
v5: ported to v2.6.39-rc6
v6: rebased onto parisc-next and net-next to avoid syscall  conflicts.
v7: ported to Linus's latest post 2.6.39 tree.
