[RFC PATCH 0/3] arc: remove CONFIG_SET_FS

Hi all, This patch series removes SET_FS support for arc. Sergey Matyukevich (3): arc: use BUILD_BUG for invalid sizes in get_user/put_user arc: provide __{get,put}_kernel_nofault arc: remove set_fs() arch/arc/Kconfig | 1 - arch/arc/include/asm/segment.h | 20 -

[RFC PATCH 1/3] arc: use BUILD_BUG for invalid sizes in get_user/put_user

From: Sergey Matyukevich Use BUILD_BUG for compile-time check of invalid sizes passed to get_user/put_user functions. Signed-off-by: Sergey Matyukevich --- arch/arc/include/asm/uaccess.h | 2 ++ 1 file changed, 2 insertions(+) diff --git a/arch/arc/include/asm/uaccess.h b/arch/arc/include/asm

[RFC PATCH 2/3] arc: provide __{get,put}_kernel_nofault

From: Sergey Matyukevich Implement the non-faulting kernel access helpers directly instead of using uaccess routines under set_fs(KERNEL_DS). Signed-off-by: Sergey Matyukevich --- arch/arc/include/asm/uaccess.h | 22 ++ 1 file changed, 22 insertions(+) diff --git a/arch/ar

[RFC PATCH 3/3] arc: remove set_fs()

From: Sergey Matyukevich Kernel __{get,put}_kernel_nofault operations are implemented for ARC. There are no other remaining arch/arc specific callers of set_fs(). So just remove it and all the supporting code. Signed-off-by: Sergey Matyukevich --- arch/arc/Kconfig | 1 - arc
