Subject: remove set_fs for riscv v2
Date: Mon,  7 Sep 2020 07:58:17 +0200	[thread overview]
Message-ID: <20200907055825.1917151-1-hch@lst.de> (raw)

Hi all,

this series converts riscv to the new set_fs less world and is on top of this
branch:

    https://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs.git/log/?h=base.set_fs

The first four patches are general improvements and enablement for all nommu
ports, and might make sense to merge through the above base branch.

Changes since v1:
 - implement __get_user_fn and __put_user_fn for the UACCESS_MEMCPY case
   and remove the small constant size optimizations in raw_copy_from_user
   and raw_copy_to_user
 - reshuffle the patch order a little
