[SPARC64]: Fix for Niagara memory corruption.

into, resulting in corruption.

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.

the next DMA it attempts, if it has been left going like this.  All

[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.

[PATCH] Kill PF_SYNCWRITE flag

A process flag to indicate whether we are doing sync io is incredibly
ugly. It also causes performance problems when one does a lot of async
io and then proceeds to sync it. Part of the io will go out as async,

previously submitted io and the synced io. For io schedulers such as CFQ,
this will cause us lost merges and suboptimal behaviour in scheduling.

by using WRITE_SYNC instead.

[PATCH] drivers/block/loop.c: don't return garbage if LOOP_SET_STATUS not called

While writing a version of losetup, I ran into the problem that the loop
device was returning total garbage.

It turns out the problem was that this losetup was only issuing the
LOOP_SET_FD ioctl and not issuing a subsequent LOOP_SET_STATUS ioctl.  This
losetup didn't have any special status to set, so it left out the call.

The deeper cause is that loop_set_fd sets the transfer function to NULL,
which causes no transfer to happen lo_do_transfer.

This patch fixes the problem by setting transfer to transfer_none in
loop_set_fd.

[PATCH] make kernel warn about incorrectly sized partitions

Sometimes partitions claim to be larger than the reported capacity of a
disk device.  This patch makes the kernel warn about those partitions.

We still permit these patitions to be used.  Quoting Andries Brouwer
<Andries.Brouwer@cwi.nl>:

 Case 1: The kernel is mistaken about the size of the disk.  (There are
 commands to clip a disk to a certain capacity, there are jumpers to tell a
 disk that it should report a certain capacity etc.  Usually this is because
 of BIOS bugs.  In bad cases the machine will crash in the BIOS and hence fail
 to boot if the disk reports full capacity.) In such cases actually accessing
 the blocks of the partition may work fine, or may work fine after running an
 unclip utility.  I wrote "setmax" some years ago precisely for this reason.

 Case 2: There was a messy partition table (maybe just a rounding error) but
 the actual filesystem on the partition is contained in the physical disk.
 Now using the filesystem goes without problem.

 Case 3: Both partition and filesystem extend beyond the end of the disk.  In
 forensic or debugging situations one often uses a copy of the start of a
 disk.  Now access beyond the end gives an expected I/O error.
