2008-04-18sh: Fix up __access_ok() check for nommu.Paul Mundt
Presently this only checks to see if an address is an RAM, but this doesn't work with XIP, so just always return 1. Follows m68knommu. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2008-02-14sh: make copy_to/from_user() static inlineMagnus Damm
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>

2008-01-28sh: get_user fixes and nommu consolidation.Stuart Menefy
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.
