As Al so eloquently points out, the patch is crap. The old code was fine,
the new code was bogus.
It never dereferenced a user pointer, the "->" operator was to an array
member, which gives the _address_ of the member (in user space), not an
actual dereference at all.

Patch from Daniel Jacobowitz
In order for userspace to find saved coprocessor registers, move them from
struct rt_sigframe into struct ucontext. Also allow space for glibc's
sigset_t, so that userspace and kernelspace can use the same ucontext
layout. Define the magic numbers for iWMMXt in the header file for easier
reference. Include the size of the coprocessor data in the magic numbers.
Also define magic numbers and layout for VFP, not yet saved.

NFS: Eliminate nfs_get_user_pages()
Neil Brown observed that the kmalloc() in nfs_get_user_pages() is more
likely to fail if the I/O is large enough to require the allocation of more
than a single page to keep track of all the pinned pages in the user's
buffer.
Instead of tracking one large page array per dreq/iocb, track pages per
nfs_read/write_data, just like the cached I/O path does. An array for
pages is already allocated for us by nfs_readdata_alloc() (and the write
and commit equivalents).
This is also required for adding support for vectored I/O to the NFS direct
I/O path.
The original reason to pin the user buffer and allocate all the NFS data
structures before trying to schedule I/O was to ensure all needed resources
are allocated on the client before starting to send requests. This reduces
the chance that resource exhaustion on the client will cause a short read
or write.
On the other hand, for an application making very large application I/O
requests, this means that it will be nearly impossible for the application
to make forward progress on a resource-limited client.
Thus, moving the buffer pinning functionality into the I/O scheduling
loops should be good for scalability. The next patch will do the same for
NFS data structure allocation.

NFS: "open code" the NFS direct write rescheduler
An NFSv3/v4 client must reschedule on-the-wire writes if the writes are
UNSTABLE, and the server reboots before the client can complete a
subsequent COMMIT request.
To support direct asynchronous scatter-gather writes, the write
rescheduler in fs/nfs/direct.c must not depend on the I/O parameters
in the controlling nfs_direct_req structure. iovecs can be somewhat
arbitrarily complex, so there could be an unbounded amount of information

[SPARC64]: Fix for Niagara memory corruption.
On some sun4v systems, after netboot the ethernet controller and it's
DMA mappings can be left active. The net result is that the kernel
can end up using memory the ethernet controller will continue to DMA
into, resulting in corruption.
To deal with this, we are more careful about importing IOMMU
translations which OBP has left in the IO-TLB. If the mapping maps
into an area the firmware claimed was free and available memory for
the kernel to use, we demap instead of import that IOMMU entry.
This is going to cause the network chip to take a PCI master abort on
the next DMA it attempts, if it has been left going like this. All
tests show that this is handled properly by the PCI layer and the e1000

not going to idle after the current one finishes.
- Don't rearm idle timer if there are no busy queues. Just leave the

[PATCH] cfq-iosched: correctly set ioprio on both targets
Patch originally from Vasily Tarasov <vtaras@sw.ru>
If you set io-priority of process 1 using sys_ioprio_set system call by
another process 2 (like ionice do), then cfq_init_prio_data() function
sets priority of process 2 (current) on queue of process 1 and clears
the flag, that designates change of ioprio. So the process 1 will work
like with priority of process 2.
I propose not to call cfq_init_prio_data() on io-priority change, but
only mark queue as queue with changed prority. Every time when new
request comes cfq-scheduler checks for this flag and atomaticaly changes
priority of queue to new value.
