This moves get_fs/set_fs() and friends in to asm/segment.h. The mm_segment_t definition is likewise consolidated from the _32/_64 split. This is prepatory groundwork for using the generic address space limit and verification routines across mmu/nommu configs. Signed-off-by: NPaul Mundt <lethal@linux-sh.org>

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: NPaul Mundt <lethal@linux-sh.org>

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: NMagnus Damm <damm@igel.co.jp> Signed-off-by: NPaul Mundt <lethal@linux-sh.org>

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.

When the thread_info->addr_limit changes were introduced, __access_ok() was missed in the conversion, allowing user processes to perform P1/P2 accesses under certain conditions. This has already been corrected with the nommu refactoring in later kernels. Signed-off-by: NPaul Mundt <lethal@linux-sh.org>

This adds in some more __user annotations. These weren't being handled properly in some of the __get_user and __put_user paths, so tidy those up. Signed-off-by: NPaul Mundt <lethal@linux-sh.org>

Drop TIF_USERSPACE and add addr_limit to the thread_info struct. Subsequently, use that for address checking in strnlen_user() to ward off bogus -EFAULTs. Make __strnlen_user() return 0 on exception, rather than -EFAULT. Signed-off-by: NPaul Mundt <lethal@linux-sh.org>

Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
