- clear hwif->hw in setup-pci.c before using it

- fix arch/arm/Kconfig to allow IDE only on platforms supporting it

- introduce IDE_ARCH_OBSOLETE_INIT and ide_default_io_ctl() so
  we can use generic ide_init_hwif_ports() and kill no longer needed
  <asm-arm/arch-*/ide.h> (leave broken lh7a40x and sa1100 versions)

Cross-compile tested on ARM.

Add drivers/ide/arm/ide_arm.c for simple default IDE interfaces
and clean obsolete ide_init_default_hwifs() implementations
in asm-arm/arch-{cl7500,rpc,shark}/ide.h and asm-arm26/ide.h.

This allows us to kill ide_init_default_hwifs() completely
in the next patch (because lh7a40x and sa1100 are broken).

Cross-compile tested on ARM.

Bryan Rosenburg pointed out that the definition of PT_FPSCR in
include/asm-ppc64/ptrace.h is wrong.  The patch below fixes it.

I have made a mistake in the kernel header i2o-dev.h.  All structures there
begin with the "iop" first, but in my structure the order is reversed.

Somehow we've been placing the rtas error_log file at /proc/ppc64/error_log,

This patch updates several of the ppc32 defconfigs.

From: Paul Mackerras <paulus@samba.org>

On machines with Altivec (i.e.  G4 and G5 processors), the altivec
floating-point instructions can operate in two modes: one where
denormalized inputs or outputs are truncated to zero, and one where they
aren't.  In the latter mode the processor can take an exception when it
encounters denormalized floating-point inputs or outputs rather than
dealing with them in hardware.

This patch adds code to deal properly with the exception, by emulating the
instruction that caused the exception.  Previously the kernel just switched
the altivec unit into the truncate-to-zero mode, which works but is a bit
gross.  Fortunately there are only a limited set of altivec instructions
which can generate the assist exception, so we don't have to emulate the
whole altivec instruction set.

This patch also makes sure that we always have a handler for the altivec
unavailable exception.  Without this, if you run a kernel that is not
configured for altivec support on a machine with altivec, it works fine
until a user process tries to execute an altivec instruction.  At that
point the kernel thinks it has taken an unknown exception and panics.  With
this patch it sends a SIGILL to the process instead.

This patch does nothing but fix up whitespace in three files in arch/ppc.
It deletes trailing blanks and tabs in several places and joins two lines

This patch adds preliminary support for the IBM PowerPC 750GX.  In summary
this part is a PPC750FX ramped to 1 GHz with a 1MB 4-way L2 and more
advanced I/O pipelining.  It is beginning to appear in embedded systems and
was rumored to be under evaluation inside Apple.  Tested on PVR 70020101;
please merge.
