Benjamin Herrenschmidt 12d04eef92 [POWERPC] Refactor 64 bits DMA operations
This patch completely refactors DMA operations for 64 bits powerpc. 32 bits
is untouched for now.

We use the new dev_archdata structure to add the dma operations pointer
and associated data to struct device. While at it, we also add the OF node
pointer and numa node. In the future, we might want to look into merging
that with pci_dn as well.

The old vio, pci-iommu and pci-direct DMA ops are gone. They are now replaced
by a set of generic iommu and direct DMA ops (non PCI specific) that can be
used by bus types. The toplevel implementation is now inline.

Stephen Rothwell caf81329c3 [POWERPC] Merge iSeries i/o operations with the rest
This patch changes the io operations so that they are out of line if
CONFIG_PPC_ISERIES is set and includes a firmware feature check in
that case.

Michael Ellerman ca652c9396 [POWERPC] iseries: Move iommu_table_cb into platforms/iseries
Although we pass the address of an iommu_table_cb to HvCallXm_getTceTableParms,
we don't actually need the structure definition anywhere except in the
iseries iommu code, so move the struct in there.

Stephen Rothwell 8bff05b052 [POWERPC] iseries: A new iSeries console
This driver uses the hvc_console.c infrastructure that is used by the
pSeries virtual and RTAS consoles.  This will allow us to make viocons.c
obsolete and is another step along the way to a combined kernel (as
viocons could not coexist with CONFIG_VT).

Michael Ellerman a9ea2101aa [PATCH] powerpc: iseries: Remove pointless iSeries_(restart|power_off|halt)
These routines just call through to the mf routines, so point ppc_md straight
at the mf routines. We need to pass the cmd through to mf_reboot to make it
work, but that seems reasonable.

Michael Ellerman 260de22faa [PATCH] powerpc: iseries: mf related cleanups
Some cleanups in the iSeries code.
 - Make mf_display_progress() check mf_initialized rather than the caller.
 - Set mf_initialized in mf_init() rather than in setup.c
 - Then move mf_initialized into mf.c, the only place it's used.
 - Move the mf related logic from iSeries_progress() to mf_display_progress()
 - Use a #define to size the pending_event_prealloc array
 - Use that define in the initialsation loop rather than sizeof jiggery pokery
 - Remove stupid comment(s)
 - Mark stuff static and/or __init

David Gibson 1888e7b51c [PATCH] powerpc: Remove ItLpRegSave area from the paca
On iSeries, the paca contains, amongst other things an ItLpRegSave
structure used by the hypervisor to save registers.  The hypervisor
locates this area through a pointer at the beginning of the paca, so
the structure itself can be located elsewhere.  This patch moves the
reg_save area out into its own array.  This reduces the amount of
iSeries specific gunk which is visible to general powerpc code via
paca.h

Built and booted on POWER5 LPAR and iSeries RS64.
