Change the threshold number of descriptors used to trigger CMB writes.
The vendor reports that under certain conditions this will reduce the
number of unnecessary tx interrupts and improve rx performance.

This change is lifted directly from vendor version 1.2.40.2 of the L1
driver.

Fixed rare issue that 'lv1_net_start_rx_dma failed, status=-9" was shown
in dmesg.  This meant restarting rx DMA had been rejected by the hypervisor.
This issue would caused if the guest os requested starting DMA when
the hypervisor thought the DMA was in progress.
The state machine for DMA status of the hypervisor would be updated
by processing interrupt in the hypervisor.
Thus we should wait for the interrupt delivery before restarting
DMA.

gelic: TX descriptor handling cleanup

        - Emitted return value of NETDEV_TX_LOCKED when DMA map or kick
          failure.
          Now it would free the skb, update drop packet statistics
          and return OK. Requested from Jeff Garzik.
        - Enable tx queue if number of free descriptors are more than 2
        - Fixed descriptor leak if dma map for second descriptor failed
        - Stopped calling xmit handler from interrupt handler in order
          to recheck tx queue.  Instead, call appropriate helper functions.

If just one, the file is SSDT, but if 3 instances,

Split ACPI_DEBUG into function trace enabled and not enabled.

Function trace is most of the ACPI_DEBUG costs, but is
not much of use for kernel ACPI debugging.

Size of kernel image increased on test compile:
+ 48k  (Full ACPI_DEBUG)
+ 35k  (ACPI_DEBUG with function trace compiled out)

Performance without function trace is also much better.

Also remove ACPI_LV_DEBUG_OBJECT from default debug level as
a lot vendors let Store (value, debug) in their code and this
might confuse users when it pops up in syslog.

Recent Vaios (C, AR, N, FE) need some special initialization
sequence to enable Fn keys interrupts through the Embedded
Controller. Moreover Fn keys have to be decoded internally
using ACPI methods to get the key code.
Thus a new DMI table to add SNC init time callbacks and new
mappings for model-specific key code to generic sony-laptop
code have been added.

The backlight class does all the locking needed for sysfs access, but
offers no API to interface to that locking without an layer violation.

Since we need to mutex-lock procfs access, implement in-driver locking for
brightness.  It will go away the day thinkpad-acpi procfs goes away, or the
backlight class gives us a way to use its locks without a layer violation.
