compat: move compat_siginfo_t definition to asm/compat.h

2012-10-05T18:05:16+00:00

This is a preparatory patch for the introduction of NT_SIGINFO elf note.

Make the location of compat_siginfo_t uniform across eight architectures
which have it.  Now it can be pulled in by including asm/compat.h or
linux/compat.h.

Most of the copies are verbatim.  compat_uid[32]_t had to be replaced by
__compat_uid[32]_t.  compat_uptr_t had to be moved up before
compat_siginfo_t in asm/compat.h on a several architectures (tile already
had it moved up).  compat_sigval_t had to be relocated from linux/compat.h
to asm/compat.h.

Mark arguments to certain syscalls as being const

2010-08-13T23:53:13+00:00

Mark arguments to certain system calls as being const where they should be but
aren't.  The list includes:

 (*) The filename arguments of various stat syscalls, execve(), various utimes
     syscalls and some mount syscalls.

 (*) The filename arguments of some syscall helpers relating to the above.

 (*) The buffer argument of various write syscalls.

sysctl: s390 Use the compat_sys_sysctl

2009-11-06T11:53:24+00:00

Now that we have a generic 32bit compatibility implementation
there is no need for s390 to implement it's own.

[S390] Convert sys_execve to function with parameters.

[S390] Convert sys_clone to function with parameters.

2009-09-22T20:58:43+00:00

Use function parameters instead of accessing the pt_regs structure
to get the parameters.
Also merge the 31 and 64 bit versions since they are identical.

compat: generic compat get/settimeofday

2008-10-16T18:21:33+00:00

Nothing arch specific in get/settimeofday.  The details of the timeval
conversion varied a little from arch to arch, but all with the same
results.

Also add an extern declaration for sys_tz to linux/time.h because externs
in .c files are fowned upon.  I'll kill the externs in various other files
in a sparate patch.
