Working on it but as usual uaccess.h is quite a quiz. What's the status of this? With current linux-mips git I still get the problem. As a reminder, the error is: CC fs/compat_ioctl.o fs/compat_ioctl.c: In function 'fd_ioctl_trans': fs/compat_ioctl.c:1831: error: read-only variable '__gu_val' used as 'asm' output fs/compat_ioctl.c:1831: error: read-only variable '__gu_val' used as 'asm' output fs/compat_ioctl.c:1831: error: read-only variable '__gu_val' used as 'asm' output fs/compat_ioctl.c:1831: error: read-only variable '__gu_val' used as 'asm' output make[1]: *** [fs/compat_ioctl.o] Error 1 -- Martin Michlmayr http://www.cyrius.com/
