ctc driver is replaced by a new ctcm driver.
The ctcm driver supports the channel-to-channel connections of the

connectivity.
This patch removes the functions of the old ctc driver.

The transmit packet descriptor consists of four 32-bit words, with word 3
upper bits overloaded depending upon the condition of its bits 3 and 4.
The driver currently duplicates all word 2 and some word 3 register bit
definitions unnecessarily and also uses a set of nested structures in its
definition of the TPD without good cause. This patch adds a lengthy
comment describing the TPD, eliminates duplicate TPD bit definitions,
and simplifies the TPD structure itself. It also expands the TSO check
to correctly handle custom checksum versus TSO processing using the revised
TPD definitions. Finally, shorten some variable names in the transmit
processing path to reduce line lengths, rename some variables to better
describe their purpose (e.g., nseg versus m), and add a comment or two
to better describe what the code is doing.

The L1 tx packet descriptor expects TCP Header Length to be expressed as a
number of 32-bit dwords.  The atl1 driver uses tcp_hdrlen() to populate the
field, but tcp_hdrlen() returns the header length in bytes, not in dwords.
Add a shift to convert tcp_hdrlen() to dwords when we write it to the tpd.

Also, some of our bit assignments are made to the wrong tpd words.  Change
those to the correct words.

Finally, since all this fixes TSO, enable TSO by default.

The future atl2 driver and the existing atl1 driver can share certain
functions and definitions.  Move these shareable functions and definitions
out of atl1-specific files and into atlx.c and atlx.h.  Some transitory
hackery will be present until atl2 is merged.

Reduce the number of source files by moving ethtool, hw, and param
functions from separate files into atl1_main.c, then rename it to just
atl1.c.

Move all atl1-specific definitions from atl1_hw.h to atl1.h.

Commit a0c1e907 added code to futex.c
to detect whether futex_atomic_cmpxchg_inatomic was implemented at run
time:

+       curval = cmpxchg_futex_value_locked(NULL, 0, 0);
+       if (curval == -EFAULT)
+               futex_cmpxchg_enabled = 1;

This is bogus on parisc, since page zero in kernel virtual space is the
gateway page for syscall entry, and should not be read from the kernel.
(That, and we really don't like the kernel faulting on its own address
 space...)

Commit 721fdf34 introduced a subtle bug
by accidently removing the "static" from iodc_dbuf. This resulted in, what
appeared to be, a trap without *current set to a task. Probably the result of
a trap in real mode while calling firmware.

Also do other misc clean ups. Since the only input from firmware is non
blocking, share iodc_dbuf between input and output, and spinlock the
only callers.

This essentially reverts commit 71fc47a9
("ACPI: basic initramfs DSDT override support"), because the code simply
isn't ready.

It did ugly things to the init sequence to populate the rootfs image
early, but that just ended up showing other problems with the whole
approach.  The fact is, the VFS layer simply isn't initialized this
early, and the relevant ACPI code should either run much later, or this
shouldn't be done at all.

For 2.6.25, we'll just pick the latter option.  We can revisit this
concept later if necessary.
