Sheng Yang ad8ba2cd44 KVM: Add kvm_arch_sync_events to sync with asynchronize events
kvm_arch_sync_events is introduced to quiet down all other events may happen
contemporary with VM destroy process, like IRQ handler and work struct for
assigned device.

For kvm_arch_sync_events is called at the very beginning of kvm_destroy_vm(), so
the state of KVM here is legal and can provide a environment to quiet down other
events.

Geoff Levand 0047656e2a powerpc/ps3: Move ps3_mm_add_memory to device_initcall
Change the PS3 hotplug memory routine ps3_mm_add_memory() from
a core_initcall to a device_initcall.

core_initcall routines run before the powerpc topology_init()
startup routine, which is a subsys_initcall, resulting in
failure of ps3_mm_add_memory() when CONFIG_NUMA=y.  When
ps3_mm_add_memory() fails the system will boot with just the
128 MiB of boot memory

Dave Hansen 06eccea6c3 powerpc/mm: Fix numa reserve bootmem page selection
Fix the powerpc NUMA reserve bootmem page selection logic.

commit 8f64e1f2d1 (powerpc: Reserve
in bootmem lmb reserved regions that cross NUMA nodes) changed
the logic for how the powerpc LMB reserved regions were converted
to bootmen reserved regions.  As the folowing discussion reports,
the new logic was not correct.

mark_reserved_regions_for_nid() goes through each LMB on the
system that specifies a reserved area.  It searches for
active regions that intersect with that LMB and are on the
specified node.  It attempts to bootmem-reserve only the area
where the active region and the reserved LMB intersect.  We
can not reserve things on other nodes as they may not have
bootmem structures allocated, yet.

We base the size of the bootmem reservation on two possible
things.  Normally, we just make the reservation start and
stop exactly at the start and end of the LMB.

However, the LMB reservations are not aware of NUMA nodes and
on occasion a single LMB may cross into several adjacent
active regions.  Those may even be on different NUMA nodes
and will require separate calls to the bootmem reserve
functions.  So, the bootmem reservation must be trimmed to
fit inside the current active region.

That's all fine and dandy, but we trim the reservation
in a page-aligned fashion.  That's bad because we start the
reservation at a non-page-aligned address: physbase.

The reservation may only span 2 bytes, but that those bytes
may span two pfns and cause a reserve_size of 2*PAGE_SIZE.

Take the case where you reserve 0x2 bytes at 0x0fff and
where the active region ends at 0x1000.  You'll jump into
that if() statment, but node_ar.end_pfn=0x1 and
start_pfn=0x0.  You'll end up with a reserve_size=0x1000,
and then call

  reserve_bootmem_node(node, physbase=0xfff, size=0x1000);

0x1000 may not be on the same node as 0xfff.  Oops.

In almost all the vm code, end_<anything> is not inclusive.
If you have an end_pfn of 0x1234, page 0x1234 is not
included in the range.  Using PFN_UP instead of the
(>> >> PAGE_SHIFT) will make this consistent with the other VM
code.

We also need to do math for the reserved size with physbase
instead of start_pfn.  node_ar.end_pfn << PAGE_SHIFT is
*precisely* the end of the node.  However,
(start_pfn << PAGE_SHIFT) is *NOT* precisely the beginning
of the reserved area.  That is, of course, physbase.
If we don't use physbase here, the reserve_size can be
made too large.

Benjamin Herrenschmidt 5b11abfdb5 powerpc/pci: mmap anonymous memory when legacy_mem doesn't exist
The new legacy_mem file in sysfs is causing problems with X on machines
that don't support legacy memory access. The way I initially implemented
it, we would fail with -ENXIO when trying to mmap it, thus exposing to
X that we do support the API but there is no legacy memory.

Unfortunately, X poor error handling is causing it to fail to start when
it gets this error.

This implements a workaround hack that instead maps anonymous memory
instead (using shmem if VM_SHARED is set, just like /dev/zero does).

Grant Likely e489a44e24 powerpc/5200: Bugfix for PCI mapping of memory and IMMR
This patch ensures that memory gets properly mapped into the PCI
address space.  Without this patch, the memory window BAR is left
at whatever value happened to be loaded into the BAR when Linux
was booted.  Without this patch, memory could end up getting mapped
at any of the 1G address boundaries instead of at '0' where Linux
expects it.

Similarly, this patch also ensures that the internally memory mapped
registers (IMMR) are mapped to the correct PCI address range.

Without this patch, PCI appears to work correctly until a PCI
device is inserted which DMAs into memory.

Robert Jennings 69b052e828 powerpc/pseries: Correct VIO bus accounting problem in CMO env.
In the VIO bus code the wrappers for dma alloc_coherent and free_coherent
calls are rounding to IOMMU_PAGE_SIZE.  Taking a look at the underlying
calls, the actual mapping is promoted to PAGE_SIZE.  Changing the
rounding in these two functions fixes under-reporting the entitlement
used by the system.  Without this change, the system could run out of
entitlement before it believes it has and incur mapping failures at the
firmware level.

Also in the VIO bus code, the wrapper for dma map_sg is not exiting in
an error path where it should.  Rather than fall through to code for the
success case, this patch adds the return that is needed in the error path.

Stephen Rothwell b17b3df161 powerpc/ps3: The lv1_ routines have u64 parameters
We just fix up the reference parameters as the others are dealt with by
arithmetic promotion rules and don't cause warnings.

This removes warnings like this:

arch/powerpc/platforms/ps3/interrupt.c:327: warning: passing argument 1 of 'lv1_construct_event_receive_port' from incompatible pointer type

Also, these:

drivers/ps3/ps3-vuart.c:462: warning: passing argument 4 of 'ps3_vuart_raw_read' from incompatible pointer type
drivers/ps3/ps3-vuart.c:592: warning: passing argument 4 of 'ps3_vuart_raw_read' from incompatible pointer type

Stephen Rothwell 494fd07a88 powerpc/ps3: Use dma_addr_t down through the stack
Push the dma_addr_t type usage all the way down to where the actual
values are manipulated.

Now that u64 is "unsigned long long", this removes warnings like:

arch/powerpc/platforms/ps3/system-bus.c:532: warning: passing argument 4 of 'ps3_dma_map' from incompatible pointer type
arch/powerpc/platforms/ps3/system-bus.c:649: warning: passing argument 4 of 'ps3_dma_map' from incompatible pointer type
