Subject: [PATCH v2 0/4] MIPS: Remove get_fs/set_fs
Date: Wed, 31 Mar 2021 13:55:57 +0200	[thread overview]
Message-ID: <20210331115603.146159-1-tsbogend@alpha.franken.de> (raw)

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
