This adds a device ID for the Aerocomm Radio Modem, which uses the
cp2102. I'm sure changing num_bulk_in/num_bulk_out to NUM_DONT_CARE
is the wrong fix, but this is the only device I have with a cp2102,
so I have no idea what a good global value would be, if there is one.
Zero didn't work with this device.

When a device cannot handle the smallest previously limited transfer
size (64 blocks) without stalling, limit the device to the amount of
packets that fit in a platform native page.
The lowest possible limit is PAGE_CACHE_SIZE, so if the device is ever
used on a platform that has larger than 8K pages, you lose unless you
can convince the device firmware folks to fix the issue.

This patch against 2.6.23 sparc-2.6.git contains a number of minor
cleanups of the sparc serial drivers. Initially I fixed this build
warning:
WARNING: vmlinux.o(.text+0x107a2c): Section mismatch: reference to .init.text:add_preferred_console (between 'sunserial_console_match' and 'sunserial_console_termios')
which is done by declaring sunserial_console_match() as __init. This
resulted in build warnings on sunserial_current_minor. To resolve
these the variable was changed so it is no longer global, and to hide
operations on it inside 2 new functions. These functions handle the
UART minor handling code that is common to all sparc serial drivers.
These changes allowed to clean up the uart counters in all the sparc
serial drivers, and the administration of minor device numbers.
Lastly, sunserial_console_termios() does not need to be exported since
it is only called from non-modular code.
Sadly, the following build warning still exists:
WARNING: vmlinux.o(__ksymtab+0x2910): Section mismatch: reference to .init.text:sunserial_console_match (between '__ksymtab_sunserial_console_match' and '__ksymtab_sunserial_unregister_minors')
This could be resolved by not exporting sunserial_console_match(), but
this is not possible at the moment because it is being called from
modular code. On the other hand, this is a bogus warning since it
comes from a ksymtab section.

The saa7134 video driver starts dropping frames when used together with the
saa7134-alsa driver. Frames are dropped because when an audio event is waiting
the driver simply ignores the interrupt and passes it on to the saa7134-alsa
interrupt handler. The alsa interrupt handler in turn acknowledges all types
of events thus clearing the pending video events as well. Fix by only masking
out the audio event in the video interrupt handler and by only acknowledging
the audio event in the alsa driver.

The period handling in saa7134-alsa is broken in two ways. First, the
minimum number of periods of two does not work, because the dma is setup
two periods ahead in the irq handler. Fix the minimum to four periods.
Second, the code assumes that the number of periods is divisible by two,
which isn't always the case on ALSA. Fix by adding a constraint.

The vlan module cleanup function starts with
vlan_netlink_fini();
vlan_ioctl_set(NULL);
The first call removes all the vlan devices and
the second one closes the vlan ioctl.
AFAIS there's a tiny race window between these two
calls - after rtnl unregistered all the vlans, but
the ioctl handler isn't set to NULL yet, user can
manage to call this ioctl and create one vlan device,
and that this function will later BUG_ON seeing
non-emply hashes.
I think, that we must first close the vlan ioctl
and only after this remove all the vlans with the
vlan_netlink_fini() call.

Packets can be left in the RX ring if the NAPI budget is reached.
This is caused by storing the latest rx index at the beginning of
bnx2_rx_int(). We may not process all the work up to this index
if the budget is reached and so some packets in the RX ring may rot
when we later check for more work using this stored rx index.
The fix is to not store this latest hw index and only store the
processed rx index. We use a new function bnx2_get_hw_rx_cons()
to fetch the latest hw rx index.

Recently, Wang Chen submitted a patch
(d30f53aeb3) to move a call to netif_rx(skb)
after a subsequent reference to skb, because netif_rx may call kfree_skb on
its argument. netif_rx_ni calls netif_rx, so the same problem occurs in
the files below.
I have left the updating of dev->last_rx after the calls to netif_rx_ni
because it seems time dependent, but moved the other field updates before.

Ultimately to implement /proc perfectly we need an implementation of
d_revalidate because files and directories can be removed behind the back
of the VFS, and d_revalidate is the only way we can let the VFS know that
this has happened.
Unfortunately the linux VFS can not cope with anything in the path to a
mount point going away. So a proper d_revalidate method that calls d_drop
also needs to call have_submounts which is moderately expensive, so you
really don't want a d_revalidate method that unconditionally calls it, but
instead only calls it when the backing object has really gone away.
proc generic entries only disappear on module_unload (when not counting the
fledgling network namespace) so it is quite rare that we actually encounter
that case and has not actually caused us real world trouble yet.
So until we get a proper test for keeping dentries in the dcache fix the
current d_revalidate method by completely removing it. This returns us to
the current status quo.
So with CONFIG_NETNS=n things should look as they have always looked.
For CONFIG_NETNS=y things work most of the time but there are a few rare
corner cases that don't behave properly. As the network namespace is
barely present in 2.6.24 this should not be a problem.
