linux-toradex.git/include/asm-sh/uaccess_32.h, branch v2.6.25.4 Linux kernel for Apalis and Colibri modules sh: make copy_to/from_user() static inline 2008-02-14T05:22:09+00:00 Magnus Damm magnus.damm@gmail.com 2008-02-07T10:50:52+00:00 1e6760c5c4589d02a6877fb256b99c33dd8f1ede This patch changes copy_from_user() and copy_to_user() from macros into static inline functions. This way we can use them as function pointers. Also unify the 64 bit and 32 bit versions. Signed-off-by: Magnus Damm <damm@igel.co.jp> Signed-off-by: Paul Mundt <lethal@linux-sh.org>

sh: get_user fixes and nommu consolidation. 2008-01-28T04:18:59+00:00 Stuart Menefy stuart.menefy@st.com 2007-11-30T09:16:23+00:00 0fb19dcb64ec4bd9934eee26ce66417fe028ffd8 When a get_user(to, from++) is called the pointer increment is performed after its first usage, in the specific after the __add_ok invokation. This causes a wrong get_user return value, putting a wrong character in the destination variable. This patch solves the problem using a new temporary pointer. Additionally this reworks the use of the register banks, allowing for consolidation between the MMU and nommu implementations.
