To: linux-kernel; +Cc: Dave Jones
Dave Jones already removed some of the useless __KERNEL_SYSCALLS__
defines in various files, this gets rid of almost all the others.
Replacing execve() is nontrivial, so I left those in for now.
For all the other system calls that are currently used from inside
the kernel, calling the sys_* function directly should always
have an identical effect.
tested on s390 and x86_64, patch applies on 2.6.3-mm4 and current bk head.

My idea was to finally eliminate __KERNEL_SYSCALLS__ without breaking
the in-tree drivers, so I changed all I could.
This patch leaves the syscalls in device drivers and fixes all
necessary uses in init/*.c.
Maybe we can find a better solution for calling execve in do_linuxrc(),
run_init_process() and ____call_usermodehelper(). Then a #warning can
be added __KERNEL_SYSCALLS__ is defined.
