Because the data field was never filled and a binary sysctl handler was
never written this sysctl has never been usable through the sys_sysctl
interface.  So just remove the binary sysctl number.  Making the kernel
sanity checks happy.

[POWERPC] virtex bug fix: Use canonical value for AC97 interrupt xparams

2007-12-07T00:43:55+00:00

The ml300 and ml403 xparameters.h files use different macros for the
AC97 interrupt pin assignments.  This normalizes them to a canonical
value similar to what EDK generates for most other devices.  This is
needed to get ml300 support to compile in arch/ppc.

xmon is broken under arch/ppc so remove it from the defconfig.

[POWERPC] Fix 8xx build breakage due to _tlbie changes

2007-11-20T07:42:00+00:00

My changes to _tlbie to fix 4xx unfortunately broke 8xx build in a
couple of places.  This fixes it.

[POWERPC] 4xx: Use virtual PVR value to init FPU on arch/ppc 440EP

2007-11-19T14:22:20+00:00

This fixes arch/ppc 440EP platforms to setup the FPU correctly.  A virtual
PVR is used, as 440GR platforms share an identical hardware PVR value and do
not have an FPU.

[POWERPC] Avoid unpaired stwcx. on some processors

2007-11-13T05:22:43+00:00

The context switch code in the kernel issues a dummy stwcx. to clear the
reservation, as recommended by the architecture.  However, some processors
can have issues if this stwcx to address A occurs while the reservation
is already held to a different address B.  To avoid this problem, the dummy
stwcx. needs to be paired with a dummy lwarx to the same address.

This adds the dummy lwarx, and creates a cpu feature bit to indicate
which cpus are affected.  Tested on mpc8641_hpcn_defconfig in
arch/powerpc; build tested in arch/ppc.
