powerpc/fsl_pci: Fix P2P bridge handling for MPC83xx PCIe controllers
It appears that we wrongly calculate dev_base for type1 config cycles.
The thing is: we shouldn't subtract hose->first_busno because PCI core
sets PCI primary, secondary and subordinate bus numbers, and PCIe
controller actually takes the registers into account. So we should use
just bus->number.
Also, according to MPC8315 reference manual, primary bus number should
always remain 0. We have PPC_INDIRECT_TYPE_SURPRESS_PRIMARY_BUS quirk
in indirect_pci.c, but since 83xx is somewhat special, it doesn't use
indirect_pci.c routines, so we have to implement the quirk specifically

powerpc/pseries: Track previous CPPR values to correctly EOI interrupts
At the moment when we EOI an interrupt we set the CPPR back to 0xFF
regardless of its previous value. This could lead to problems if we
take an interrupt with a priority of 5, but before EOIing it we get
an IPI which has a priority of 4. The problem is that at the moment
when we EOI the IPI we will set the CPPR to 0xFF, but it should
really be set back to 5 (the previous priority).
To keep track of the previous CPPR values we create the xics_cppr
structure that has an array for CPPR values and an index pointing
to the current priority. This can easily grow if new priorities get
added in the future.
This will also be useful because the partition adjunct option of
upcoming machines will update the H_XIRR hcall to accept the CPPR
as a parameter.

powerpc/pseries: Serialize cpu hotplug operations during deactivate Vs deallocate
Currently the cpu-allocation/deallocation process comprises of two steps:
- Set the indicators and to update the device tree with DLPAR node
information.
- Online/offline the allocated/deallocated CPU.
This is achieved by writing to the sysfs tunables "probe" during allocation
and "release" during deallocation.
At the sametime, the userspace can independently online/offline the CPUs of
the system using the sysfs tunable "online".
It is quite possible that when a userspace tool offlines a CPU
for the purpose of deallocation and is in the process of updating the device
tree, some other userspace tool could bring the CPU back online by writing to
the "online" sysfs tunable thereby causing the deallocate process to fail.
The solution to this is to serialize writes to the "probe/release" sysfs
tunable with the writes to the "online" sysfs tunable.

removing the resource's node from the device tree and then returning the
resource to firmware via the rtas set-indicator call. To add a resource, it
is first obtained from firmware via the rtas set-indicator call and then a
new device tree node is created using the ibm,configure-coinnector rtas call
and added to the device tree.
This patch provides the kernel DLPAR infrastructure in a new filed named

This reworks the interface between the mediabay and the rest
of the world so that:
- Any macio_driver can now have a mediabay_event callback
which will be called when that driver sits on a mediabay and
it's been either plugged or unplugged. The device type is
passed as an argument. We can now move all the IDE cruft
into the IDE driver itself
- A check_media_bay() function can be used to take a peek
at the type of device currently in the bay if any, a cleaner
variant of the previous function with the same name.
- A pair of lock/unlock functions are exposed to allow the
IDE driver to block the hotplug callbacks during the initial
setup and probing of the bay in order to avoid nasty race
conditions.
- The mediabay code no longer needs to spin on the status
register of the IDE interface when it detects an IDE device,
this is done just fine by the IDE code itself
Overall, less code, simpler, and allows for another driver
than our old drivers/ide based one.

powerpc/kvm: Sync guest visible MMU state
Currently userspace has no chance to find out which virtual address space we're

unpleasent when debugging, as gdb and the monitor don't work on virtual
addresses.
This patch exports enough of the MMU segment state to userspace to make
debugging work and thus also includes the groundwork for migration.

powerpc/mm: Fix pgtable cache cleanup with CONFIG_PPC_SUBPAGE_PROT
Commit
a0668cdc154e54bf0c85182e0535eea237d53146 cleans up the handling
of kmem_caches for allocating various levels of pagetables.
Unfortunately, it conflicts badly with CONFIG_PPC_SUBPAGE_PROT, due to
the latter's cleverly hidden technique of adding some extra allocation
space to the top level page directory to store the extra information
it needs.
Since that extra allocation really doesn't fit into the cleaned up
page directory allocating scheme, this patch alters
CONFIG_PPC_SUBPAGE_PROT to instead allocate its struct
subpage_prot_table as part of the mm_context_t.

This reverts commit
f20941f334d8fdb6b598658979709b4e94cd034b.
Sergei Shtylyov notes "You call min() on uncomparables [in
mwdma_clip_to_pio()], i.e. mwdma_to_pio[] contains XFER_PIO_* and
adev->pio_mode - XFER_PIO_0 yields you a mode number. Thus the second
argument will always "win" as a minimal one"
Bartlomiej Zolnierkiewicz adds "There are more issues with the patch related
to mwdma_clip_to_pio(). The function can return values between 0 and
4 which obviously won't work well for the new code below for values
>2 (i.e. resulting in out-of-bounds array access for the common-case
of dev->pio_mode == XFER_PIO_4)."
Bartlomiej Zolnierkiewicz also notes the patch is incomplete, failing to
update MWDMA mode masks.
