* Add generic sys_old_mmap()Christoph Hellwig2010-03-121-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Add a generic implementation of the old mmap() syscall, which expects its argument in a memory block and switch all architectures over to use it.

* CRIS: Wire up syscalls signalfd4 to writev.Jesper Nilsson2009-04-281-0/+8
| | | | | | Adds sys_signalfd4, sys_eventfd2, sys_epoll_create1, sys_dup3, sys_pipe2, sys_inotify_init1, sys_preadv, sys_pwritev for both CRISv10 and CRISv32.
* [CVE-2009-0029] Rename old_readdir to sys_old_readdirHeiko Carstens2009-01-141-1/+1
| | | | | | This way it matches the generic system call name convention. Signed-off-by: Heiko Carstens <heiko.carstens@de.ibm.com>
* [CRIS] Move header files from include to arch/cris/include.Jesper Nilsson2008-10-291-2/+2
| | | | | | | Change all users of header files to correct path. Remove some unneeded headers for arch-v32. Signed-off-by: Jesper Nilsson <jesper.nilsson@axis.com>

* CRIS v32: Update entry.S to working order.Jesper Nilsson2008-02-081-18/+63
| | | | | | | - Remove oldset parameter. - Utilise delay-slot for parameter moving. - Add kernel_execve as break 13. - Add new kernel syscalls.

* kbuild: cris use generic asm-offsets.h supportSam Ravnborg2005-09-091-1/+1
| | | | | | | | | | Cris has a dedicated asm-offsets.c file per subarchitecture. So a symlink is created to put the desired asm-offsets.c file in $(ARCH)/kernel This is absolutely not good practice, but it was the trick used in the rest of the cris code.
