https://git.shady.money/linux/atom?h=v3.22010-04-07T15:38:05Zfrv: fix kernel/user segment handling in NOMMU mode2010-04-07T15:38:05ZDavid Howellsdhowells@redhat.com2010-04-06T21:35:09Zurn:sha1:08dc179b9b00cfbed006ae6f5d0e471ef79dc69c
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.
