[PATCH v2 0/4] MIPS: Remove get_fs/set_fs

From: Thomas Bogendoerfer
Date: Wed Mar 31 2021 - 07:57:09 EST


This series replaces get_fs/set_fs and removes it from MIPS arch code.

Changes in v2:
- added copy_from_kernel_nofault_allowed() for !EVA to restrict
access of __get/__put_kernel_nofault
- replaced __get_data macro by helper functions
- removed leftover set_fs calls in ftrace.c
- further cleanup uaccess.h

Thomas Bogendoerfer (4):
MIPS: kernel: Remove not needed set_fs calls
MIPS: uaccess: Added __get/__put_kernel_nofault
MIPS: uaccess: Remove get_fs/set_fs call sites
MIPS: Remove get_fs/set_fs
