The variable 'scratch' is always initialized before it's used. The
conditional which is responsible for initialization of 'scratch' will
always evaluate 'true' when the first loop iteration occurs, and thus,
it's properly initialized. GCC doesn't see this, of course, so using
the uninitialized_var() macro seems to work for silencing this case.

Removing a card often results in -ENOMEDIUM or -EILSEQ so we previously

The addition of a new device has so far implied a specialization of
these masks. While they identify 8168c devices, they can be expected
to be further refined as they have been by Realtek so far.

Broadly speaking the 8168c* share some common code which will
be factored in __rtl_hw_start_8168cp. The 8168b* share some
code too but it will be a bit different.
Any change of behavior should be confined to the currently
unidentified 8168 chipsets. They will not be applied the Tx
performance tweak and will emit a warning instead.

I can not argue strongly for (or against) a specific ordering
on a purely technical ground but the patch avoids to swallow
Realtek's changes in one big, hard-to-read gulp.
Let aside the way the RxConfig register is written (see
rtl_set_rx_tx_config_registers / RxConfig / rtl_set_rx_mode),
this change brings the registers write ordering closer with
Realtek's driver one (version 8.006.00) for the 8168 chipsets.
More 8168 specific code which touches the Configx registers will
be added in the section covered by Cfg9346_UnLock / Cfg9346_Lock.
This code should not be the cause of regression for 810x and
8110 users.

Avoid probing the io-ports in case an IDE PCI controller is present and it
uses the legacy iobases. If we still want to enforce the probing, we do
ide_generic.probe_mask=0x3f
on the kernel command line. The iobase checking code is
adapted from drivers/ata/pata_legacy.c after converting hex
pci ids into their corresponding macros in <linux/pci_ids.h>.
Also, check only BAR0/2 resources since those are guaranteed
by the workaround in drivers/pci/probe.c:pci_setup_device().

drive->no_[io_32bit,unmask] is set (this is checked later inside
set_[io_32bit,unmaskirq]() anywyay and keeps consistency with

The 3215 console irq handler used to schedule a tasklet. However the
console irq handler also gets called from the infamous cio_tpi()
function. Which in turn does something like
local_bh_disable()
[call console irq handler]
_local_bh_enable()
_local_bh_enable() prevents execution of softirqs, which is intended
within cio_tpi(). However there might be a new softirq pending because
irq handler scheduled a tasklet.
In order to prevent this behaviour we just get rid of the tasklet.
It's not doing much anyway.

The s390 console drivers use the unblank callback of the console
structure to flush the console buffer. In case of a panic or a
reboot the CPU doing the callback can block on the console i/o.
The other CPUs in the system continue to work. For panic this is
not a good idea.

always just !scsw_stctl(&request->irb.scsw).

If an asynchronous HiperSockets queue runs full, no further packet

skbs back to the stack is triggered only by a 10-seconds qdio timer.
This timer has been introduced for low multicast traffic scenarios
to guarantee freeing of skbs in a limited amount of time. For high
HiperSocket multicast traffic scenarios progress checking on the
