Fixes for memcg/memory hotplug.
While memory hotplug allocate/free memmap, page_cgroup doesn't free
page_cgroup at OFFLINE when page_cgroup is allocated via bootomem.
(Because freeing bootmem requires special care.)
Then, if page_cgroup is allocated by bootmem and memmap is freed/allocated
by memory hotplug, page_cgroup->page == page is no longer true.
But current MEM_ONLINE handler doesn't check it and update
page_cgroup->page if it's not necessary to allocate page_cgroup. (This
was not found because memmap is not freed if SPARSEMEM_VMEMMAP is y.)
And I noticed that MEM_ONLINE can be called against "part of section".
So, freeing page_cgroup at CANCEL_ONLINE will cause trouble. (freeing
used page_cgroup) Don't rollback at CANCEL.
One more, current memory hotplug notifier is stopped by slub because it
sets NOTIFY_STOP_MASK to return vaule. So, page_cgroup's callback never
be called. (low priority than slub now.)
I think this slub's behavior is not intentional(BUG). and fixes it.
Another way to be considered about page_cgroup allocation:
- free page_cgroup at OFFLINE even if it's from bootmem
and remove specieal handler. But it requires more changes.

Jim Radford has reported that the vmap subsystem rewrite was sometimes
causing his VIVT ARM system to behave strangely (seemed like going into
infinite loops trying to fault in pages to userspace).
We determined that the problem was most likely due to a cache aliasing
issue. flush_cache_vunmap was only being called at the moment the page
tables were to be taken down, however with lazy unmapping, this can happen
after the page has subsequently been freed and allocated for something
else. The dangling alias may still have dirty data attached to it.
The fix for this problem is to do the cache flushing when the caller has
called vunmap -- it would be a bug for them to write anything else to the
mapping at that point.
That appeared to solve Jim's problems.

Tecra M4 sometimes forget what it is and reports bogus data via DMI
which makes the machine evade broken suspend matching and thus fail
suspend/resume. This patch updates piix_broken_suspend() such that it
can match such case. As the borked DMI data is a bit generic,
matching many entries to make the match more specific is necessary.
As the usual DMI matching is limited to four entries, this patch uses
hard coded manual matching.

When resizing a CQ, MTTs associated with the old CQE buffer were not
freed. As a result, if any app used resize CQ repeatedly, all MTTs
were eventually exhausted, which led to all memory registration
operations failing until the driver is reloaded.
Once the RESIZE_CQ command returns successfully from FW, FW no longer
accesses the old CQ buffer, so it is safe to deallocate the MTT
entries used by the old CQ buffer.
Finally, if the RESIZE_CQ command fails, the MTTs allocated for the
new CQEs buffer also need to be de-allocated.

It turns out that on Cell, on a kernel with CONFIG_VIRT_CPU_ACCOUNTING
= y, if a program sets the SO (summary overflow) bit in the XER and
then does a system call, the SO bit in CR0 will be set on return
regardless of whether the system call detected an error. Since CR0.SO
is used as the error indication from the system call, this means that
all system calls appear to fail.
The reason is that the workaround for the timebase bug on Cell uses a
compare instruction. With CONFIG_VIRT_CPU_ACCOUNTING = y, the
ACCOUNT_CPU_USER_ENTRY macro reads the timebase, so we end up doing a
compare instruction, which copies XER.SO to CR0.SO. Since we were
doing this in the system call entry patch after clearing CR0.SO but
before saving the CR, this meant that the saved CR image had CR0.SO
set if XER.SO was set on entry.
This fixes it by moving the clearing of CR0.SO to after the
ACCOUNT_CPU_USER_ENTRY call in the system call entry path.

Kexec/kdump currently fails on the IBM QS2x blades when the kexec happens
on a CPU other than the initial boot CPU. It turns out that this is the
result of mpic_init trying to set affinity of each interrupt vector to the
current boot CPU.
As far as I can tell, the same problem is likely to exist on any
secondary MPIC, because they have to deliver interrupts to the first
output all the time. There are two potential solutions for this: either
not set up affinity at all for secondary MPICs, or assume that a single
CPU output is connected to the upstream interrupt controller and hardcode
affinity to that per architecture.
This patch implements the second approach, defaulting to the first output.
Currently, all known secondary MPICs are routed to their upstream port
using the first destination, so we hardcode that.

The MSI capture logic for the axon bridge can sometimes
lose interrupts in case of high DMA and interrupt load,
when it signals an MSI interrupt to the MPIC interrupt
controller while we are already handling another MSI.
Each MSI vector gets written into a FIFO buffer in main
memory using DMA, and that DMA access is normally flushed
by the actual interrupt packet on the IOIF. An MMIO
register in the MSIC holds the position of the last
entry in the FIFO buffer that was written. However,
reading that position does not flush the DMA, so that
we can observe stale data in the buffer.
In a stress test, we have observed the DMA to arrive
up to 14 microseconds after reading the register.
This patch works around this problem by retrying the
access to the FIFO buffer.
We can reliably detect the conditioning by writing
an invalid MSI vector into the FIFO buffer after
reading from it, assuming that all MSIs we get
are valid. After detecting an invalid MSI vector,
we udelay(1) in the interrupt cascade for up to
100 times before giving up.

I got a bug report about a distro kernel not booting on a particular

> Inode-cache hash table entries: 524288 (order: 6, 4194304 bytes)
> freeing bootmem node 0
I've reproduced this on 2.6.27.7. It is caused by commit
8f64e1f2d1 ("powerpc: Reserve in bootmem
lmb reserved regions that cross NUMA nodes").
The problem is that Jon took a loop which was (in pseudocode):
for_each_node(nid)
NODE_DATA(nid) = careful_alloc(nid);
setup_bootmem(nid);
reserve_node_bootmem(nid);
and broke it up into:
for_each_node(nid)
NODE_DATA(nid) = careful_alloc(nid);
setup_bootmem(nid);
for_each_node(nid)
reserve_node_bootmem(nid);
The issue comes in when the 'careful_alloc()' is called on a node with
no memory. It falls back to using bootmem from a previously-initialized
node. But, bootmem has not yet been reserved when Jon's patch is
applied. It gives back bogus memory (0xc000000000000000) and pukes
later in boot.
The following patch collapses the loop back together. It also breaks
the mark_reserved_regions_for_nid() code out into a function and adds
some comments. I think a huge part of introducing this bug is because
for loop was too long and hard to read.
The actual bug fix here is the:
+ if (end_pfn <= node->node_start_pfn ||
+ start_pfn >= node_end_pfn)
+ continue;

Currently, some PCIe devices on POWER6 machines do not get interrupts
assigned correctly. The problem is that OF doesn't create an
"interrupt" property for them. The fix is for of_irq_map_pci to fall
back to using the value in the PCI interrupt-pin register in config
space, as we do when there is no OF device-tree node for the device.
I have verified that this works fine with a pair of Squib-E SAS
