2010-06-02sh: PIO disabling for x3proto and urquell.Paul Mundt
urquell only provides PIO in the PCI case, while the x3proto board never had a working PCIe controller, so it can simply disable it outright. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2010-06-02sh: mach-sdk7786: conditionally disable PIO support.Paul Mundt
SDK7786 only supports PIO via the PCI I/O space, so we disable PIO completely for the non-PCI case. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2010-06-02sh: support for platforms without PIO.Paul Mundt
This extends some of the existing special casing for HAS_IOPORT platforms and gets it to the point where platforms can begin to conditionally select it. The major changes here are that the PIO routines themselves go away completely, including all of the machvec port mapping wrappers. With this in place it's possible for any non-machvec abusing platform to disable PIO completely. At present this is left as an opt-in until the abusers are the odd ones out instead of the majority.

This patch is V2 of the MMCIF romImage boot support for sh7724 and the Ecovec board.

2010-05-27ptrace: unify FDPIC implementationsMike Frysinger
The Blackfin/FRV/SuperH guys all have the same exact FDPIC ptrace code in their arch handlers (since they were probably copied & pasted). Since these ptrace interfaces are an arch independent aspect of the FDPIC code, unify them in the common ptrace code so new FDPIC ports don't need to copy and paste this fundamental stuff yet again.

2010-05-26Revert "endian: #define __BYTE_ORDER"Linus Torvalds
This reverts commit b3b77c8caef1750ebeea1054e39e358550ea9f55, which was also totally broken (see commit 0d2daf5cc858 that reverted the crc32 version of it). As reported by Stephen Rothwell, it causes problems on big-endian machines: > In file included from fs/jfs/jfs_types.h:33, > from fs/jfs/jfs_incore.h:26, > from fs/jfs/file.c:22: > fs/jfs/endian24.h:36:101: warning: "__LITTLE_ENDIAN" is not defined The kernel has never had that crazy "__BYTE_ORDER == __LITTLE_ENDIAN" model.

2010-05-25endian: #define __BYTE_ORDERJoakim Tjernlund
Linux does not define __BYTE_ORDER in its endian header files which makes some header files bend backwards to get at the current endian. Lets #define __BYTE_ORDER in big_endian.h/litte_endian.h to make it easier for header files that are used in user space too. In userspace the convention is that 1. _both_ __LITTLE_ENDIAN and __BIG_ENDIAN are defined, 2. you have to test for e.g. __BYTE_ORDER == __BIG_ENDIAN.

2010-05-25sh: handle early calls to return_address() when using dwarf unwinder.Paul Mundt
The dwarf unwinder ties in to an early initcall, but it's possible that return_address() calls will be made prior to that. This implements some additional error handling in to the dwarf unwinder as well as an exit path in the return_address() case to bail out if the unwinder hasn't come up yet. This fixes a NULL pointer deref in early boot when mempool_alloc() blows up on the not-yet-ready mempool via dwarf_unwind_stack(). Signed-off-by: Paul Mundt <lethal@linux-sh.org>

2010-05-19panic: Allow warnings to set different taint flagsBen Hutchings
WARN() is used in some places to report firmware or hardware bugs that are then worked-around. These bugs do not affect the stability of the kernel and should not set the flag for TAINT_WARN. To allow for this, add WARN_TAINT() and WARN_TAINT_ONCE() macros that take a taint number as argument. Architectures that implement warnings using trap instructions instead of calls to warn_slowpath_*() now implement __WARN_TAINT(taint) instead of __WARN().
