ARM: 9113/1: uaccess: remove set_fs() implementation
There are no remaining callers of set_fs(), so just remove it
along with all associated code that operates on
thread_info->addr_limit.
There are still further optimizations that can be done:
- In get_user(), the address check could be moved entirely
into the out of line code, rather than passing a constant
as an argument,
- I assume the DACR handling can be simplified as we now
only change it during user access when CONFIG_CPU_SW_DOMAIN_PAN
is set, but not during set_fs().
