Use the same signal frame alignment calculations as the underlying
architecture. x86_64 appeared to do this, but the "- 8" was really
subtracting 8 * sizeof(struct rt_sigframe) rather than 8 bytes.
UML/i386 might have been OK, but I changed the calculation to match
i386 just to be sure.

Fix VIA quirks that were recently broken by Alan Cox in the upstream
kernel (commit 1597cacbe39802d86656d1f2e6329895bd2ef531).
My understanding is that pci_find_present() doesn't work yet at the time
the quirks are run. So I used a two-step quirk as is done for some other
quirks already. First we detect the VIA south bridges and set the right
low and high device limits, then we are ready to actually run the quirks on
the affected devices.

But keep it as a dprintk
The message can be generated in a quite normal situation:
If a 'lock' request is interrupted, then the lock client needs to
record that the server has the lock, incase it does.
When we come the unlock, the server might say it doesn't, even
though we think it does (or might) and this generates the message.

When expanding the stack, we don't currently check if the VMA will cross
into an area of the address space that is reserved for hugetlb pages.
Subsequent faults on the expanded portion of such a VMA will confuse the
low-level MMU code, resulting in an OOPS. Check for this.

This reverts commit 0c0b3ae68ec93b1db5c637d294647d1cca0df763.
Quoth David:
"Jeff, please revert
It's wrong. We had a lengthy analysis of this piece of code
several months ago, and it is correct.
Consider, if we run the loop and we get an error
the following happens:
1) attempt of ifb_init_one(i) fails, therefore we should
not try to "ifb_free_one()" on "i" since it failed
2) the loop iteration first increments "i", then it
check for error
Therefore we must decrement "i" twice before the first
free during the cleanup. One to "undo" the for() loop
increment, and one to "skip" the ifb_init_one() case which
failed."

This is based on a patch by Eric W. Biederman, who pointed out that pid
namespaces are still fake, and we only have one ever active.
So for the time being, we can modify any code which could access
tsk->nsproxy->pid_ns during task exit to just use &init_pid_ns instead,
and move the exit_task_namespaces call in do_exit() back above
exit_notify(), so that an exiting nfs server has a valid tsk->sighand to
work with.
Long term, pulling pid_ns out of nsproxy might be the cleanest solution.

Nick Piggin points out that page accounting on MIPS multiple ZERO_PAGEs
is not maintained by its move_pte, and could lead to freeing a ZERO_PAGE.
Instead of complicating that move_pte, just forget the minor optimization
when mremapping, and change the one thing which needed it for correctness
- filemap_xip use ZERO_PAGE(0) throughout instead of according to address.

When the world was a simple and static place setting up irqs was easy.
It sufficed to allocate a linux irq number and a find a free cpu
vector we could receive that linux irq on. In those days it was
a safe assumption that any allocated vector was actually in use
so after one global pass through all of the vectors we would have
none left.
These days things are much more dynamic with interrupt controllers
(in the form of MSI or MSI-X) appearing on plug in cards and linux
irqs appearing and disappearing. As these irqs come and go vectors
are allocated and freed, invalidating the ancient assumption that all
allocated vectors stayed in use forever.
So this patch modifies the vector allocator to walk through every
possible vector before giving up, and to check to see if a vector
is in use before assigning it. With these changes we stop leaking
freed vectors and it becomes possible to allocate and free irq vectors
all day long.
This changed was modeled after the vector allocator on x86_64 where
this limitation has already been removed. In essence we don't update
the static variables that hold the position of the last vector we
allocated until have successfully allocated another vector. This
allows us to detect if we have completed one complete scan through
all of the possible vectors.

These series of patches result of UFS1 write support stress testing, like
running fsx-linux, untar and build linux kernel etc
We pass from ufs::get_block_t to levels below: pointer to the current page, to
make possible things like reallocation of blocks on the fly, and we also uses
this pointer for indication, what actually we allocate data block or meta data
block, but currently we make decision about what we allocate on the wrong
level, this may and cause oops if we allocate blocks in some special order.

Fix exit race by splitting the nsproxy putting into two pieces. First
piece reduces the nsproxy refcount. If we dropped the last reference, then
it puts the mnt_ns, and returns the nsproxy as a hint to the caller. Else
it returns NULL. The second piece of exiting task namespaces sets
tsk->nsproxy to NULL, and drops the references to other namespaces and
frees the nsproxy only if an nsproxy was passed in.
A little awkward and should probably be reworked, but hopefully it fixes
the NFS oops.
