*	openrisc: sanitize use of orig_gpr11	Jonas Bonn	2012-03-06	1	-5/+2
\| \| \| \| \| \| \| \| \| \|	The pt_regs struct had both a 'syscallno' field and an 'orig_gpr11' field and it wasn't really clear how these were supposed to be used. This patch removes the syscallno field altogether and makes orig_gpr11 work more like other architectures: keep track of syscall number in progress or hold -1 for non-syscall exceptions.

*	OpenRISC: System calls	Jonas Bonn	2011-07-22	1	-0/+77
	The OpenRISC Linux kernel conforms to the "generic" syscall interface which contains only the reduced set of syscalls deemed necessary for new architectures. Unfortunately, the uClibc port for OpenRISC does not fully support this reduced set; as such, an additional patch available out-of-tree needs to be applied to the kernel in order to use the current uClibc. This is just a temporary measure until the libc port can be straightened out; it is likely that OpenRISC will make the transition to glibc shortly where the generic syscall interface is better supported.
