Increased storvsc ringbuffer and max_io_requests. This now more
closely mimics the numbers on Hyper-V. And will allow more IO requests
to take place for the SCSI driver.
Max_IO is set to double from what it was before, Hyper-V allows it and
we have had appliance builder requests to see if it was a problem to
increase the number.
Ringbuffer size for storvsc is now increased because I have seen A few buffer

Fix missing functions for net_device_ops.
It's a bug when porting the drivers from 2.6.27 to 2.6.32. In 2.6.27,
the default functions for Ethernet, like eth_change_mtu(), were assigned
by ether_setup(). But in 2.6.32, these function pointers moved to
net_device_ops structure and no longer be assigned in ether_setup(). So
we need to set these functions in our driver code. It will ensure the
MTU won't be set beyond 1500. Otherwise, this can cause an error on the
server side, because the HyperV linux driver doesn't support jumbo frame
yet.

Certain USB devices, such as the Nokia X6 mobile phone, don't expose any
endpoint descriptors on some of their interfaces. If the ACM driver is forced
to probe all interfaces on a device the a NULL pointer dereference will occur
when the ACM driver attempts to use the endpoint of the alternative settings.
One way to get the ACM driver to probe all the interfaces is by using the
/sys/bus/usb/drivers/cdc_acm/new_id interface.
This patch checks that the endpoint pointer for the current alternate settings
is non-NULL before using it.

When using the remove sysfs file, the device configuration is set to -1
(unconfigured). This eventually unbind drivers with the bandwidth_mutex
held. Some drivers may call functions that hold said mutex, like
usb_reset_device. This is the case for rtl8187, for example. This will
lead to the same process holding the mutex twice, which deadlocks.
Besides, according to Alan Stern:
"The deadlock problem probably could be handled somehow, but there's a
separate issue: Until the usb_disable_device call finishes unbinding
the drivers, the drivers are free to continue using their allocated
bandwidth. We musn't change the bandwidth allocations until after the
unbinding is done. So this patch is indeed necessary."
Unbinding the driver before holding the bandwidth_mutex solves the
problem. If any operation after that fails, drivers are not bound again.
But that would be a problem anyway that the user may solve resetting the
device configuration to one that works, just like he would need to do in
most other failure cases.

Unfortunately some of the hardware PID belonging to auto-install CDROM
(AICD) of Novatel modems found their way into the option module. This
causes the AICD to be treated as a modem in stead of a disk. Since the
modem ports do not appear until after the AICD is ejected, this
essentially disables the modem. After a couple of minutes the AICD
should auto-eject, but it is just too long a wait. The frequency of the
failure seems to depend on both the hardware and the linux distribution.

I found a bug "by chance" in drivers/char/tty_io.c
I mean "by chance" because I was just reading the code of the
tty_find_polling_driver() to make a new tty_find_by_name() function.
In tty_find_polling_driver() the driver actually test "tty_line <=
p->num" while num refers to the number of struct tty_struct pointers
allocated for the p->ttys (p is a tty_driver), and tty_line is scanned
in a tty name, which can be for example ttyS2. Then tty_line equals 2.
And if p->num is 2, we have only p->ttys[0] and p->ttys[1], but no
p->ttys[2].
This is actually unharmful, for tty_find_polling_driver() is used only
in drivers/serial/kgdboc.c, and there's a test over there to find a
console with a matching index, which will never happen.
This is still a bug anyway.

After 02f0777a0d "vc_origin" is no
longer reset to the screen buffer before calling the con_init() hook
of the new console driver.
If the old driver wasn't using a fixed scanout buffer (e.g. the case
of vgacon) "vc_origin" may be a pointer to a VRAM location, and its
contents aren't guaranteed to be preserved after calling con_deinit()
on the old driver and con_init() on the new driver, i.e. the
subsequent console resize may fill the framebuffer with garbage.
It can be reproduced in the transition from vgacon to the nouveau
framebuffer driver: in that case the legacy VGA aperture "vc_origin"
points to becomes unreadable after fbcon_init().
This patch reverts the mentioned commit. To avoid the problem it
intended to fix, stop using "vc_scr_end" in vc_do_resize() to
calculate how many rows we have to copy (actually the code looks
simpler this way without the help of "vc_scr_end").

vortex_ioctl() was grabbing vortex_private::lock around its call to
generic_mii_ioctl(). This is no longer necessary since there are more
specific locks which the mdio_{read,write}() functions will obtain.
Worse, those functions do not save and restore IRQ flags when locking
the MII state, so interrupts will be enabled when generic_mii_ioctl()
returns.
Since there is currently no need for any function to call
mdio_{read,write}() while holding another spinlock, do not change them
to save and restore IRQ flags but remove the specification of ordering
between vortex_private::lock and vortex_private::mii_lock.
