Hi Arnd,

From: Arnd Bergmann <arnd@arndb.de>

There are no remaining callers of set_fs(), so CONFIG_SET_FS
can be removed globally, along with the thread_info field and
any references to it.

This turns access_ok() into a cheaper check against TASK_SIZE_MAX.

With CONFIG_SET_FS gone, so drop all remaining references to
set_fs()/get_fs(), mm_segment_t and uaccess_kernel().

Signed-off-by: Arnd Bergmann <arnd@arndb.de>
Tested-by: Sergey Matyukevich <redacted> # for arc changes

Regards,
Sergey
