1) save the timestamp flit in the cq when we consume a CQE.

2) always compare the saved flit with the previous entry flit when
   reading the next CQE entry.  If the flits don't compare, then we
   have overflowed.

The LLD now supports proper UP state change events, so move the RDMA

In the RDMA core unregister path, kernel users will be calling down
into the T4 provider to release resources.  So we cannot detach from
the LLD until this process completes.

WARNING: at drivers/firmware/dmi_scan.c:423 dmi_matches+0x70/0x160()
dmi check: not initialized yet.

This is caused by commit aa2110cb
(ACPI: add boot option acpi=copy_dsdt to fix corrupt DSDT).
DMI is not initialized yet in acpi_early_init on ia64.

The DSDT DMI check table is x86 specific, so make it empty on other archs.
And this fixes the warnings on ia64.

When cppcheck found this flaw

[./i2c/busses/i2c-highlander.c:284]: (style) Warning - using char variable in bit operation

it was noted that the 'read'-variable could be simply removed as read_write can
only be 0 or 1 anyhow. So, we remove the flaw and simplify the code.

Drop NO_IRQ as 0 is the preferred way to describe 'no irq'
(http://lkml.org/lkml/2005/11/21/221). This change is safe, as the driver is
only used on powerpc, where NO_IRQ is 0 anyhow.
