A number of small changes to vmcp:
- Change preferred email address.
- Use PRINT_xxx machros from debug.h like most s390 drivers, define
"vmcp:" as PRINTK_HEADER and wrap error message at column 80.
- Add error number to error message.
- Update copyright, as I touched this file.
- Small whitespace diff.
- Use mutex instead of semaphore (Thanks Heiko for the patch)
- Don't register debug feature on failure.
- Check debug feature registration on init to avoid a potential oops
on unload if the debug feature could not be registered--> 2 more

When running QIOASSIST enabled qdio devices in a z/VM environment
the output queue for such devices stall in heavy workload situations.
When SQBS and EQBS instructions returns CCQ=96 qdio does not reissue
the instruction again with the register settings done by millicode
but processed the returned qdio buffer. This is wrong. qdio has to
reissue the instruction once again on CCQ=96, as we already do it
for CCQ=97.

The instructions with format RX_URRD and SI_URD and instructions
with a PC relative operand are not disassembled correctly.
For RX_URRD and SI_URD instructions find_insn sets opfrag to code[0].
The mask byte of these two formats is 0x00. table->opfrag will never
be identical to (opfrag & opmask) and no matching instruction will
be found. Set the mask byte to 0xff to actually check byte 0 against
the table.
For PC relative instructions the (unsigned) offset value needs to be
casted to an signed integer so that negative branch offsets are
handled correctly.

The SCSI code can be compiled modular, but BLK_DEV_BSG currently cannot,

This patch adds support for DLPAR memory add to the eHEA driver. To detect
whether memory was added the driver uses its own memory mapping table and
checks for kernel addresses whether they're located in already known memory
sections. If not the function ehea_rereg_mrs() is triggered which performs
a rebuild of the mapping table and a re-registration of the global memory
region.

Teach LDM about a new field encountered with Windows Vista.
This fixes LDM for people using Vista who have disabled drive letter
assignment from one or more volumes. Doing this introduces a so far
unknown field in the LDM database in the VOL5 VBLK structure which
causes the LDM driver to fail to parse the VBLK structure and hence LDM
fails to parse the disk altogether. This patch teaches the driver about
this field.
