an occasion to munmap and repeat. Okay, let's quieten the compiler (but I
would prefer it if pprev, rb_link and rb_parent were meaningful in that

get_order() takes byte-sized input, not a page-granular one.
Irrespective of this fix I'm inclined to believe that this doesn't work
right anyway - bitmap_allocate_region() has an implicit assumption of
'pos' being suitable for 'order', which this function doesn't seem to
enforce (and since it's being called with a byte-granular value there's no
reason to believe that the callers would make sure device_addr is passed
accordingly - it's also not documented that way).

radeon: misc corrections
I have a new PCI-E radeon RV380 series card (PCI device ID 5b64) that
hangs in my sparc64 boxes when the init scripts set the font. The problem
goes away if I disable acceleration.
I haven't figured out that bug yet, but along the way I found some
corrections to make based upon some auditing.
1) The RB2D_DC_FLUSH_ALL value used by the kernel fb driver
and the XORG video driver differ. I've made the kernel
match what XORG is using.
2) In radeonfb_engine_reset() we have top-level code structure
that roughly looks like:
if (family is 300, 350, or V350)
do this;
else
do that;
...
if (family is NOT 300, OR
family is NOT 350, OR
family is NOT V350)
do another thing;
this last conditional makes no sense, is always true,
and obviously was likely meant to be "family is NOT
300, 350, or V350". So I've made the code match the
intent.

Fix USB storage hang on command abort
Okay, I found the cause of the hang. It is a simple bug in the USB

This patch (as1125) fixes a bug in the USB scatter-gather library.
Early exit from the S-G initialization loop does not reset the count of

The guilty commit turned out to be
08da591e14cf87247ec09b17c350235157a92fc3
("ide: add ide_device_{get,put}() helpers"). ide_device_put() is called
before kref_put() in ide_cd_put() so IDE device is already gone by the time
ide_cd_release() is reached.
Fix it by calling ide_device_get() before kref_get() and ide_device_put()
after kref_put() in all affected device drivers.
v2:
Brown paper bag time. In v1 cd->drive was referenced after dropping last
reference on cd object (which could result in OOPS in ide_device_put() as
reported/debugged by Mariusz Kozlowski). Fix it by caching cd->drive in
the local variable (fix other device drivers too).

vt: Deadlock workaround
2.6.26 corrected the mutex locking on tty resizing to fix the case where
you could get the tty/vt sizing out of sync. That turns out to have a

The actual fix is really major and I've got it lined up as part of the ops
changes for 2.6.28 so for 2.6.26/2.6.27 it is safer to reintroduce this
ages old minor bug.

======================================================
This testcase results in an mlock() failure with errno 14 that is EFAULT,
but it has nowhere been specified that mlock() will return EFAULT. When I
tested the same on older kernels like 2.6.18, I got the correct result i.e
errno 12 (ENOMEM).
I think in source code mlock(2), setting errno ENOMEM has been missed in
do_mlock() , on mlock_fixup() failure.
SUSv3 requires the following behavior frmo mlock(2).
[ENOMEM]
Some or all of the address range specified by the addr and
len arguments does not correspond to valid mapped pages
in the address space of the process.
[EAGAIN]
Some or all of the memory identified by the operation could not
be locked when the call was made.
This rule isn't so nice and slighly strange. but many people think
POSIX/SUS compliance is important.

atmel_spi: fix hang due to missed interrupt
For some time my at91sam9260 board with JFFS2 on serial flash (m25p80)
would hang when accessing the serial flash and SPI bus. Slowing the SPI
clock down to 9 MHz reduced the occurrence of the hang from "always"
during boot to a nuisance level that allowed other SW development to
continue. Finally had to address this issue when an application stresses
the I/O to always cause a hang.
Hang seems to be caused by a missed SPI interrupt, so that the task ends
up waiting forever after calling spi_sync(). The fix has 2 parts. First
is to halt the DMA engine before the "current" PDC registers are loaded.
This ensures that the "next" registers are loaded before the DMA operation
takes off. The second part of the fix is a kludge that adds a
"completion" interrupt in case the ENDRX interrupt for the last segment of
the DMA chaining operation was missed.
The patch allows the SPI clock for the serial flash to be increased from 9
MHz to 15 MHz (or more?). No hangs or SPI overruns were encountered.
Haavard: while this patch does indeed improve things, I still see overruns
and CRC errors on my NGW100 board when running the DataFlash at 10 MHz.
However, I think some improvement is better than nothing, so I'm passing
this on for inclusion in 2.6.27.

For these cases the callers make sure:
1) The cpus indicated are online.
2) The current cpu is not in the list of indicated cpus.
Therefore we can pass a pointer to the mask directly.
One of the motivations in this transformation is to make use of
"&cpumask_of_cpu(cpu)" which evaluates to a pointer to constant
data in the kernel and thus takes up no stack space.
Hopefully someone in the future will change the interface of
arch_send_call_function_ipi() such that it passes a const cpumask_t
