Add support to domain builders for loading kernels with physical addresses in the elf paddr and entry fields.
Add a new __xen_guest header field to distinguish between kernels with
the previous use of the paddr field and the new use.
Add a new __xen_guest header field to control the kernel entry point,
since the elf header entry field now points to a physical address.
This header field is also useful for supporting alternative entry
points in kernel images which run both on xen and native.
Also add a kernel config option to control whether the resulting kernel
should include compatibility code to run on Xen 3.0.2 or whether such
code such be left out, resulting in a kernel which will only run on
newer Xen versions. Default to having compatibility enabled.
Kernels built with the new use of the elf header fields would otherwise

Fix injection of guest faults resulting from failed injection of a
previous event. We enter an infinite loop if the original failed
injection cannot be fixed up by Xen (e.g., because it's not a shadow
pagetable issue).
The RHEL4 HVM guest hang issue was actually a side effect of
change-set 9699. In the rhel4 guest hang rc.sysinit init-script was
calls kmodule program to probe the hardware. The kmodule uses the kudzu
library call probeDevices(). For probing the graphics hardware in the
vbe_get_mode_info() function, sets up the environment and goes into the
vm86 mode to do the int x10 call. For returning back to protected mode
it sets up a int 0xff call. At the time of calling the int 0xff the
guest process pages were not filled up. And it was causing an infinite
loop of vmexits with the IDT_VECTORING_INFO on the int 0xff instruction.
The reason for the infinite loop is changeset 9699. With that
the guest page fault was always getting overridden by the int 0xff gp
fault coming from the IDT_VECTORING_INFO. With the attached patch if VMM
is injecting exceptions like page faults or gp faults then
IDT_VECTORING_INFO field does not override it, and that breaks the
vmexit infinite loop for the rhel4.

Xm-tests 01_memset_basic_pos.test and 03_memset_random_pos.test start
domUs with 64MB of memory,
and assume that all of that memory is available in the domU. They then
perform various xm memset tests
based on the assumed starting conditions.
When netback & blkback are comiled into the domU kernel, they eat about
5MB. This mismatch will cause
01_memset_basic_pos.test to fail every time. 03_memset_random_pos.test
will probably fail, but can
pass with some lucky numbers from the random number generator.
This patch changes both tests to read the starting memory allocation from
the balloon driver in the domU.

This patch changes to format in which EIP is printed to be consistent on 64-bit regardless of whether the addresses
leading bits are set or clear. It additionally changes the formatting so that trailing spaces are avoided, and it
suppresses the printing of empty records. It also prevents combining records with identical EIP but from different
domains.
It further changes the type of some variables from plain int to unsigned int, as that is yielding more efficient code
on x86-64 (signed 32-bit array indices require explicit sign extension, whereas in most cases an extra copy can be
