request_queue and device struct must have the same value of a segment
size limit. This patch adds blk_queue_segment_boundary in
__scsi_alloc_queue so LLDs don't need to call both
blk_queue_segment_boundary and set_dma_max_seg_size. A LLD can change
the default value (64KB) can call device_dma_parameters accessors like
pci_set_dma_max_seg_size when allocating scsi_host.

This adds struct device_dma_parameters in struct pci_dev and properly
sets up a pointer in struct device.
The default max_segment_size is set to 64K, same to the block layer's
default value.

The clock to generate the desired baudrate with the MPSC is first divided
by the Baud Rate Generator (BRG) and then by the MPSC itself. So, when the
BRG divider is changed, the MPSC divider must also be changed to generate
the correct baudrate. During MPSC initialization, the BRG divider is
changed but the MPSC divider isn't changed until much later. This results
in some printk's coming out garbled. To fix that, set the MPSC divider at
the same time that the BRG divider is changed.

Some ports seem to be unable to drain their transmitters on shut down. Such a
problem can occur if the port is programmed for hardware imposed flow control,
characters are in the FIFO but the CTS signal is inactive.
Normally, this isn't a problem because most places where we wait for the
transmitter to drain have a time-out. However, there is no timeout in the
suspend path.
Give a port 30ms to drain; this is an arbitary value chosen to avoid long
delays if there are many such ports in the system, while giving a reasonable
chance for a single port to drain. Should a port not drain within this
timeout, issue a warning.

When we boot, serial ports remain in low power mode until they're used either
by userspace or for the kernel console.
However, if you suspend the system, and then resume, all serial ports will be
taken out of low power mode. This is bad news for embedded devices where this
can mean higher power consumption.
Only bring a serial port out of low power mode if the port is being used as
the kernel console, or is in use by userspace.

Allow the private_data field to be specified in platform_data for the
standard 8250/16550 UART. This field is used by DW APB type UARTs and
without this patch it's only possible to set this field when registering
the port by hand. If private_data is not set then the driver will
potentially oops with a NULL pointer dereference.

with reverting "x86, serial: convert legacy COM ports to platform devices",
we will have the serial console before the port is probled again.
uart_add_one_port==>uart_configure_port==>set_mcttrl(port, 0) will clear
the DTR setting by uart_set_options(). then I will lose my output from
serial console again.
So try to keep DTR in uart_configure_port()

of_iomap calls ioremap, and so should be matched with an iounmap. At the
two error returns, the result of calling of_iomap is only stored in a local
variable, so these error paths need to call iounmap. Furthermore, this
function ultimately stores the result of of_iomap in an array that is local
to the file. These values should be iounmapped at some point. I have
added a corresponding call to iounmap at the end of the function
m8xx_remove.
The problem was found using the following semantic match.

Convert the io_req_t members to unsigned int, to allow use on machines with
more than 16 bits worth of IO ports (i.e. secondary busses on ppc64, etc).
There was only a couple of places in drivers where a change was needed. I
left printk formats alone (there are lots of %04x-style formats in there),
mostly to not change the format on the platforms that only have 16-bit io
addresses, but also because the padding doesn't really add all that much value
most of the time.
I found only one sprintf of an address, and upsized the string accordingly (I
doubt anyone will have anywhere near INT_MAX as irq value, but at least
there's room for it now).

Currently early kernel messages, i.e., those from uncompression, go to the
debugging UART. And if it is enabled in the platform configuration, but
not initialized by the bootloader, the machine hangs, waiting for UART
status change. Besides, having those messages on another UART - typically
the console UART - may be preferrable. This patch allows selecting the
UART in kernel configuration.

After discussions with Anthony Liguori, it seems that the virtio
balloon can be made even simpler. Here's my attempt.
The device configuration tells the driver how much memory it should
take from the guest (ie. balloon size). The guest feeds the page
numbers it has taken via one virtqueue.
A second virtqueue feeds the page numbers the driver wants back: if
the device has the VIRTIO_BALLOON_F_MUST_TELL_HOST bit, then this
queue is compulsory, otherwise it's advisory (and the guest can simply
fault the pages back in).
This driver can be enhanced later to deflate the balloon via a
shrinker, oom callback or we could even go for a complete set of
in-guest regulators.

As Avi pointed out, as we continue to massage the virtio PCI ABI, we can make
things a little more friendly to users by utilizing the PCI revision field to
indicate which version of the ABI we're using. This is a hard ABI version
and incrementing it will cause the guest driver to break.
This is the necessary changes to virtio_pci to support this.

This is a PCI device that implements a transport for virtio. It allows virtio

This patch goes on top of the minor number patch. Please let me know if
you want a merged patch:
Currently virtio_blk creates the disk name combinging "vd" with 'a'++.
This will give strange names after vdz. I have implemented names up to
vdzzz - inspired by the sd.c code. That should be sufficient for now.
There is one driver in the kernel (driver/s390/block/dasd_genhd.c) that
implements names from dasda-dasdzzzz allowing even more disks. Maybe
a janitor can come up with a common implementation usable for all kind
of block device drivers.
I have tested this patch with 100 disks - seems to work.

Rusty,
currently virtio_blk uses one major number per device. While this works
quite well on most systems it is wasteful and will exhaust major numbers
on larger installations.
This patch allocates a major number on init and will use 16 minor numbers
for each disk. That will allow ~64k virtio_blk disks.

Rusty,
I currently try to make my guest boot from an virtio root device
without having an external kernel. Some of the tools that I tried
expect HDIO_GETGEO to work. The most interesting value is likely
the geo.start value to get the offset of a partition. This value
is filled by block/ioctl.c if fops->getgeo is set. This patch also
fills in some standard values for heads, sectors and cylinders.
Makes sense?

Fix bug found by Christian Borntraeger: if the other side fills all
the registered network buffers before we enable NAPI, we will never
get an interrupt. The simplest fix is to process the input queue once
on open.

Hello Rusty,
virtnet_probe already calls alloc_etherdev, which calls ether_setup.
There is no need to do that again.
