userspace to guest kernel. The flags are saved on the guest kernel
stack anyway, but some guests rely on %r11 instead.

the requirement on such being available for allocation when enabling
shadow mode, removing the potential for live migration to fail due to
fragmented memory.
Has seen little testing only so far.

Prevent returning early, so that other information gathered in this
function will not occasionally be missing for the consumer(s).

When a suspended managed domain is resumed, the checkpoint file is
removed, but xend retains a reference to the removed file. This
represents a resource leak. Fixed by ensuring that the file reference
is closed correctly.

Linux has been using the VESA capabilities field for quite a while, so
Xen should also supply it. At once, in case needed in the future, also
propagate the mode attributes field.

- use __clear_bit() rather than clear_bit()
- use switch statements instead of long series of if-s
- eliminate pointless casts

Messages prior to BUG() should always be displayed, not just when
DEBUG_TRACE_DUMP is defined (which by default it isn't). Convert them
from SHADOW_PRINTK() to SHADOW_ERROR().

Add get_- and set_other_config methods to the vTPM class. Write the
parameters into the xenstore while the domain is running prefixing it
with 'oc_'. Also I add the methods to the C library as well as the
documentation.

- Use openpty(), which does the same as the sequence
of open(), grantpt(), unlockpt(), ptsname(), tcgetattr()
simplifies code
- Check return code from tcsetattr()
- sprintf() -> snprintf()
- OpenBSD lacks POSIX grantpt() and unlockpt()
requires use of openpty()
- Solaris lacks POSIX openpty() via feedback from SUN (John Levon)
implement openpty() for Solaris, tested and ok'd by SUN (John
Levon)

Allow the network bridging setup script to choose an alternative
network interface if it is determined that the root is mounted using
NFS, which is assumed to be done over the NIC serving the default
gw. In this case the prefix of the device is used to find other
devices, i.e., if eth0 is the default device an alternative device may
be an other ones starting with 'eth'.

1. Command-line option 'console_timestamps' adds a timestamp prefix
to each line of Xen console output (x86 only, after CMOS has been
interrogated).
2. Clean up prefix handling and vanity banner info.

Changing LINUX_VER causes us to clone the wrong repository so instead
use the kernel's "kernelrelease" target to figure out the correct
Linux version.
