sh: migrate to arch/sh/include/

This follows the sparc changes a439fe51a1f8eb087c22dd24d69cebae4a3addac. Most of the moving about was done with Sam's directions at: http://marc.info/?l=linux-sh&m=121724823706062&w=2 with subsequent hacking and fixups entirely my fault. Signed-off-by: Sam Ravnborg Signed-off-by: Paul Mundt

sh: Workaround for __put_user_asm() bug with gcc 4.x on big-endian.

2008-07-28T09:36:13+00:00

I think this problem is GCC(4.1.2) bug. Syscall "getdents" returned "dirent->d_off" is always 0. I think other EB enviroment have same problem. Problem code 0c03c954 : : c03c97a: 58 f7 mov.l @(28,r15),r8 !-> offset (high) c03c97c: 59 f8 mov.l @(32,r15),r9 !-> offset (low) c03c97e: 53 f9 mov.l @(36,r15),r3 c03c980: 54 fa mov.l @(40,r15),r4 : c03c9a0: 21 82 mov.l r8,@r1 !offset(high) -> dirent->d_off It's workaround patch.

sh: Initial consolidation of the _32/_64 uaccess split.

2008-07-28T09:10:29+00:00

This consolidates everything but the bare assembly routines, which we will sync up in a follow-up patch. Signed-off-by: Paul Mundt

sh: Consolidate addr/access_ok across mmu/nommu on 32bit.

sh: Consolidate segment modifiers across mmu/nommu systems.

2008-07-28T09:10:28+00:00

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: Paul Mundt

sh: Fix up __access_ok() check for nommu.

2008-04-18T16:50:02+00:00

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

sh: make copy_to/from_user() static inline

2008-02-14T05:22:09+00:00

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 Signed-off-by: Paul Mundt

sh: Fix get_user()/put_user() build error.

2008-01-28T04:19:02+00:00

Fixes the build error caused by -Werror on gcc 3.x compilers: arch/sh/kernel/signal_32.c: In function `sys_sigaction': arch/sh/kernel/signal_32.c:66: warning: initialization discards qualifiers from pointer target type arch/sh/kernel/signal_32.c:67: warning: initialization discards qualifiers from pointer target type arch/sh/kernel/signal_32.c:69: warning: initialization discards qualifiers from pointer target type arch/sh/kernel/signal_32.c:70: warning: initialization discards qualifiers from pointer target type The mismatch in question was introduced by commit-id 9c5a4eec79b3eb8876d2e7fddfa1e040a7650e55.

sh: get_user fixes and nommu consolidation.

2008-01-28T04:18:59+00:00

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.
