Nathan Lynch d608df5c7d [POWERPC] Maple U3 HT - reject inappropriate config space access
When there is a PCI-X mode 2 capable device behind the HT<->PCI-X
bridge, the pci core decides that the device has the extended 4K
config space, even though the bus is not operating in mode 2.  This is
because the u3_ht pci ops silently accept offsets greater than 255 but
use only the 8 least significant bits, which means reading at offset
0x100 gets the data at offset 0x0, and causes confusion for lspci.

Reject accesses to configuration space offsets greater than 255.

Arnd Bergmann 7d452c326c [POWERPC] powerpc: fix building gdb against asm/ptrace.h
Ulrich Weigand found a bug with the current version of the
asm-powerpc/ptrace.h that prevents building at least the
SPU target version of gdb, since some ptrace opcodes are
not defined.

The problem seems to have originated in the merging of 32 and
64 bit versions of that file, the problem is that some opcodes
are only valid on 64 bit kernels, but are also used by 32 bit
programs, so they can't depends on the __powerpc64__ symbol.

Update to the PowerPC PCI error recovery code.

Add code to enable MMIO if a device driver reports that it is capable
of recovering on its own.  One anticipated use of this having a device
driver enable MMIO so that it can take a register dump, which might
then be followed by the device driver requesting a full reset.

Benjamin Herrenschmidt eeac5c142b [POWERPC] Fix G5 DART (IOMMU) race causing occasional data corruption
It seems that the occasional data corruption observed with the tg3
driver wasn't due to missing barriers after all, but rather seems to
be due to the DART (= IOMMU) in the U4 northbridge reading stale
IOMMU table entries from memory due to a race.  This fixes it by
making the CPU read the entry back from memory before using it.

Paul Mackerras f007cacffc [POWERPC] Fix MMIO ops to provide expected barrier behaviour
This changes the writeX family of functions to have a sync instruction
before the MMIO store rather than after, because the generally expected
behaviour is that the device receiving the MMIO store can be guaranteed
to see the effects of any preceding writes to normal memory.

To preserve ordering between writeX and readX, and to preserve ordering
between preceding stores and the readX, the readX family of functions
have had an sync added before the load.

Although writeX followed by spin_unlock is not officially guaranteed
to keep the writeX inside the spin-locked region unless an mmiowb()
is used, there are currently drivers that depend on the previous
behaviour on powerpc, which was that the mmiowb wasn't actually required.
Therefore we have a per-cpu flag that is set by writeX, cleared by
__raw_spin_lock and mmiowb, and tested by __raw_spin_unlock.  If it is
set, __raw_spin_unlock does a sync and clears it.

This changes both 32-bit and 64-bit readX/writeX.  32-bit already has a
sync in __raw_spin_unlock (since lwsync doesn't exist on 32-bit), and thus
doesn't need the per-cpu flag.

Tested on G5 (PPC970) and POWER5.

Olof Johansson 87fd7724d4 [POWERPC] Quiet hvc_console console output on failed opens
No other tty driver will print on the console when the open of it fails.

On systems that happen to be configured for both ttyS0 and hvc0 console,
this will keep flooding the console output.  This is most likely to
happen with systems booted between with and without hypervisor from the
same filesystem.

Let's just remove it. When it's really needed (i.e. when the open fails
and someone is trying to debug it), noone will see the output anyway. And

Mike Kravetz 57852a853b [POWERPC] powerpc: Instrument Hypervisor Calls
