the sysfs entry). Some problems with existing tests are fixed.

This patch adds the updated and newer driver plugins appearing in
2.6.17-rc4 to the 2.6.16.13 kernel. The patch needs to be placed into
the patches/linux-2.6.16.13 directory and should be removed once an
upgrade is done to 2.6.17-rc4 or later version.

and also fixes the following:
- a problem introduced by a recent change to the xenbus_driver structure
requires driver-specific data to be stored in another data structures
- removes the #define'd MIN by min/min_t
- moves the sysfs entry to /sys/devices/xen/<vtpm-%d>
- fixes a bug occurring during cancellation of requests
- updates the default configuration to also compile the TPM V1.2 driver
submitted in part 2 of this patch
- all changes made to the generic TPM driver are surrounded by #ifdef
CONFIG_XEN's.

labels. The new subcommands are 'xm resources', 'xm rmlabel', 'xm
getlabel' and 'xm dry-run'. In addition, the 'xm addlabel' subcommand
now uses an updated syntax to support labeling both domains and
resources. See the xm man page for details on each subcommand.
Beyond the new subcommands, this patch allows users to immediately see
when security checks will fail by pushing some basic security checking
into the beginning of 'xm create' and 'xm block-attach'. ACM security
attributes for block devices are added to XenStore in order to support
the final security enforcement, which will be performed in the kernel
and included in a separate patch.

Currently the ROMBIOS includes static MP tables for only four
configurations: 1-way, 2-way, 4-way, and 8-way.
This patch makes the creation of MP tables more dynamic by creating them
from within HVMLOADER based upon the VCPU number provided by the HVM
information table.
Note: Some of the information included used to create the MP tables is
still hard coded and based upon values used in the original ROMBIOS MP
tables. Data such as the CPU family/model/stepping information should
probably be made to match the information provided to the guest when
executing a CPUID.

This patch adds TCP Segmentation Offload (TSO) support to the backend.
It also advertises this fact through xenbus so that the frontend can
detect this and send through TSO requests only if it is supported.
This is done using an extra request slot which is indicated by a flag
in the first slot. In future checksum offload can be done in the same
way.
The extra request slot must not be generated if the backend does not
support the appropriate feature bits. For now this is simply feature-tso.
If the frontend detects the presence of the appropriate feature bits,
it may generate TX requests which have the appropriate request flags
set that indicates the presence of an extra request slot with the extra
information.
On the backend the extra request slot is read if and only if the request
flags are set in the TX request.
This protocol allows more feature bits to be added in future without
breaking compatibility. At least the hardware checksum bit is planned.
Even though only TSO is supported for now the code actually supports
GSO so it can be applied to any other protocol. The only missing bit
is the detection of host support for a specific GSO protocol. Once that
is added we can advertise all supported protocols to the guest.

example, /sys/devices/xen-backend/vbd-x-xxxx/statistics.
The 'statistics' directory includes the following three statistical

oo_req
is the number of requests held up due to full pipeline.
rd_req
is the number of processed READ requests.
wr_req

a) xentop -b

b) xentop -i <number>
will iterate <number> times and exit (option "n" is already used by

by removing the tags or TAGS file, and then running using the
-a option in conjunction with xargs a full list of tags will
be obtained, regardless of how many files there are.
I believe that the existing invocations of both etags and ctags are wrong:
* I don't think - is a vailid argument to etags
* xargs ctags does not handle the case where ctags is invoked
multiple times by xargs when there are too many files
to fit on one command line.

1. Remove has_long_option() and add arg_check_for_resource_list()
instead.
2. 'args' tells 'options' from 'params' by using gnu_getopt().
3. 'options' checks whether -l/--long option is specified.
4. If 'params' not given, print out 'No domain parameter given'
and usage.
5. If 'params' given multiple domains, print out
'No multiple domain parameters allowed' and usage.
6. Then it displays the resources as usual.
