2013-05-28frv: uaccess s/might_sleep/might_fault/Michael S. Tsirkin
The only reason uaccess routines might sleep is if they fault. Make this explicit. Signed-off-by: Michael S.

2010-04-07frv: fix kernel/user segment handling in NOMMU modeDavid Howells
In NOMMU mode, the FRV segment handling is broken because KERNEL_DS == USER_DS. This causes tests of the following sort: /* don't pin down non-user-based iovecs */ if (segment_eq(get_fs(), KERNEL_DS)) return NULL; to malfunction. To fix this, make USER_DS the top of RAM instead of the top of the non-IO address space, and make KERNEL_DS one more than the top of the non-IO address space. Also get rid of FRV's __addr_ok() as nothing uses it.
