2010-06-07sh: Fix up IORESOURCE_PCI_FIXED usage in pcibios_fixup_device_resources().Paul Mundt1-2/+0
pcibios_fixup_device_resources() presently skips over resources flagged with IORESOURCE_PCI_FIXED, which is a remnant of the old PCI-auto code. The only user for this at present is the Dreamast GAPSPCI code which can't tolerate any adjustments to the BARs, but a combination of the IORESOURCE_PCI_FIXED and zeroed out hose offsets does the right thing for this case already, so we simply kill off the special casing.

2010-06-02sh: support for platforms without PIO.Paul Mundt8-34/+54
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.

2010-05-26Revert "endian: #define __BYTE_ORDER"Linus Torvalds1-0/+4
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 Tjernlund1-4/+0
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 Mundt2-2/+19
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 Hutchings1-2/+2
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().
