playing games with casts of argument address to struct pt_regs * and
digging through it, we declare them as

This patch for the dummy_hcd driver prevents it from rejecting SET-ADDRESS
requests when the address is already set.  The USB 2.0 spec states that if
a device is in the ADDRESS state, it should accept and start using the new
address.  Behavior in the CONFIGURED state is undefined, but since
dummy_hcd doesn't keep track of the difference between the two states we
might as well accept the new address in any case.

This is a fix for when we encounter an alias during insert. When that
happens we move the request to dispatch, but it may happen that this
request is also the ->last_merge hint. So we may attempt to merge with
this later, when it's either in progress or already freed. Rearrange the
logic a bit so we clear the merge hint there as well. It looks more
complex than it is, the only real code change is the addition of a
cfq_remove_merge_hints() in cfq_dispatch_sort().

This cset adds the code to handle the hardware vector floating point
unit found on some ARM926 and later CPUs.  The hardware provides
an implementation for the common cases, and bounces exceptions for
other cases, which have to be handled in software, and signalling
SIGFPE as appropriate.

Add a user_struct pointer to the sigqueue structure.  Charge sigqueue
allocation and destruction to the user_struct rather than a global pool.  This
per user rlimit accounting obsoletes the global queued_signals accouting.

The patch as charges the sigqueue struct allocation to the queue that it's
pending on (the receiver of the signal).  So the owner of the queue is charged
for whoever writes to it (much like quota for a 777 file).

The patch started out charging the task which allocated the sigqueue struct.
In most cases, these are always the same user (permission for sending a
signal), so those cases are moot.  In the cases where it isn't the same user,
it's a privileged user sending a signal to another user.

It seems wrong to charge the allocation to the privleged user, when the other
user could block receipt as long as it feels.  The flipside is, someone else
can fill your queue (expectation is that someone else is privileged).  I think
it's right the way it is.  The change to revert is very small.

It turns out there is a bug in hugetlb_prefault(): with 3 level page table,
huge_pte_alloc() might return a pmd that points to a PTE page.  It happens
if the virtual address for hugetlb mmap is recycled from previously used
normal page mmap.  free_pgtables() might not scrub the pmd entry on munmap
and hugetlb_prefault skips on any pmd presence regardless what type it is.

This patch fixes some problems with handling of channel detection in the
driver.  Some systems that are IPMI 1.5 do not implement the channel query
command.  Also, the interface has to be fully up before the command is
ready.

This patch also adds a polling interface; this is required for situations
where interrupts are not running, but the system must still issue IPMI
commands, like when taking a crash dump.

It also updates the driver version to v32.
