Add missing DMA ops

2011-09-11T07:50:39Z

For the initial architecture submission, not all of the DMA ops were implemented. This patch adds the *map_page and *map_sg variants of the DMA mapping ops. This patch is currently of interest mainly to some drivers that haven't been submitted upstream yet. Signed-off-by: Jonas Bonn

openrisc: don't use pt_regs in struct sigcontext

2011-09-05T12:29:12Z

As it was decided not to export struct pt_regs to userspace, struct sigcontext shouldn't be using it either. The pt_regs struct for OpenRISC is kernel internal and the layout of the registers may change in the future. The struct user_regs_struct is what is guaranteed to remain stable, so struct sigcontext may use that instead. This patch removes the usage of struct pt_regs in struct sigcontext and makes according changes in signal.c to get the register layout right. The usp field is removed from the sigcontext structure as this information is already contained in the user_regs_struct. Signed-off-by: Jonas Bonn Reviewed-by: Emilio Cota

OpenRISC: System calls

2011-07-22T16:46:34Z

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.
