Currently qe_bd_t is used in the macro call -- dma_unmap_single,
which is a no-op on PPC32, thus error is hidden today. Starting
with 2.6.24, macro will be replaced by the empty static function,
and erroneous use of qe_bd_t will trigger compilation error.

A crash upon booting that is caused by bcm43xx has been reported [1] and
found to be due to a work queue being reinitialized while work on that
queue is still pending. This fix modifies the shutdown of work queues and
prevents periodic work from being requeued during shutdown. With this patch,
no more crashes on reboot were observed by the original reporter. I do not
get that particular failure on my system; however, when running a large
number of ifdown/ifup sequences, my system would kernel panic with the
'caps lock' light blinking at roughly a 1 Hz rate. In addition, there were
infrequent failures in the firmware that resulted in 'IRQ READY TIMEOUT'
errors. With this patch, no more of the first type of failure occur, and
incidence of the second type is greatly reduced.

This patch solves a problem that the spidernet driver sometimes fails
to handle IRQ.
The problem happens because,
- In Cell architecture, interrupts may arrive at an interrupt
controller, even if they are masked by the setting on registers of
devices. It happens when interrupt packets are sent just before
the interrupts are masked.
- spidernet interrupt handler compares interrupt reasons with
interrupt masks, so when such interrupts occurs, spidernet interrupt
handler returns IRQ_NONE.
- When all of interrupt handler return IRQ_NONE, linux kernel disables
the IRQ and it no longer delivers interrupts to the interrupt handlers.
spidernet doesn't work after above sequence, because it can't receive
interrupts.
This patch changes spidernet interrupt handler that it compares
interrupt reason with SPIDER_NET_INTX_MASK_VALUE.

Introduces a module parameter to decide whether the physical
port link state is propagated to the network stack or not.
It makes sense not to take the physical port state into account
on machines with more logical partitions that communicate
with each other. This is always possible no matter what the physical
port state is. Thus eHEA can be considered as a switch there.

One of the very first things lguest_init() does is a memcpy. On
Athlon/Duron/K7 or CyrixIII/VIA-C3 or Geode GX/LX, this tries to use
MMX.
memcpy -> _mmx_memcpy -> kernel_fpu_begin -> clts -> paravirt_ops.clts
But we haven't set paravirt_ops.clts yet, so we do the native version
and crash. The simplest solution is to use __memcpy.

Intel framebuffer mis-calculated pixel clocks.
The pixel clock (and thus both H and V sync) will be slower than requested, so
if you set the minimum allowed the display may not sync. In case of really
old CRT display it could theoretically damage it.
I'm using it with PAL TV (using RGB input - SCART connector) and the bug
prevented it from working at all (TV requirements are more strict and made the
bug visible).

I ran into a few problems.
n_tty_ioctl() for instance:
drivers/char/tty_ioctl.c:799: error: $,1rxstruct termios$,1ry has no
member named $,1rxc_ispeed$,1ry
This is calling the copy interface that is supposed to be using
a termios2 when the new interfaces are defined, however:
case TIOCGLCKTRMIOS:
if (kernel_termios_to_user_termios((struct termios __user *)arg, real_tty->termios_locked))
return -EFAULT;
return 0;
This is going to write over the end of the userspace
structure by a few bytes, and wasn't caught by you yet
because the i386 implementation is simply copy_to_user()
which does zero type checking.

The Marvell bridge chips used on HighPoint SATA cards do not seem to support
the UltraDMA modes 1, 2, and 3 as well as any MWDMA modes, so the driver needs
to account for this in the udma_filter() method. In order to achieve that, do
the following changes:
- install the method for all chips, not only HPT36x/370 and improve the code
formatting by killing the extra tabs while at it;
- add to the end of the 'switch' statement in the method cases for HPT372[AN]
and HPT374 chips upon which the known SATA cards are based;
- use hwif->ultra_mask as a default mask for the ide_dma_filter() method to
behave correctly;
- move the HPT370[A] cases below the HPT36x case for consistency.
While at it, replace the explicit UltraDMA mode masks with ATA_UDMA* constants
all over the driver...

The IDE core never marked the PCI IDE devices as being in use after succesfull
driver probe call (the devices were marked in use only while being probed), and
so was susceptible to issues caused by unsolicited PCI hotplug device removal.
So, add pci_dev_get() call to ide_scan_pcidev() and convert this function to
the kernel style, also dropping a bunch of useless curly braces from its caller,
ide_scan_pcibus() and somewhat beautifying printk() call there, while at it...

sectors per command
The MP3/MP4/AVI player "Rockchip ROCK MP3" is seen as a USB disk, but fails
if more than 128 sectors (64kB) are sent or requested in a single read or write
command, and disconnects from the USB bus.
Typical kernel log showing the problem is:
usb 3-1: reset high speed USB device using ehci_hcd and address 6
usb 3-1: reset high speed USB device using ehci_hcd and address 6
sd 14:0:0:0: [sdb] Result: hostbyte=0x07 driverbyte=0x00

sd 14:0:0:0: [sdb] Result: hostbyte=0x07 driverbyte=0x00
end_request: I/O error, dev sdb, sector 32
usb 3-1: USB disconnect, address 6
This patch works around the device limitation by adding "Rockchip ROCK MP3"
