David Vrabel a585912dcc arm: support zImage format kernels for dom0
Allow a zImage format kernel to be used for dom0.  zImages are (by
default) hardcoded with the RAM location so adjust the RAM in the
memory map to match the physical memory map (0x80000000).

Vmlinux ELF images are loaded using a hack to locate the RAM so the
IPA is the same as the kernel's VA so the elf loader does the right
thing.  If an ELF image is loaded the RAM will be located at
0xC0000000 (as before).

Andrew Cooper 6c1e5375c1 CONFIG: remove #ifdef __ia64__ from the x86 arch tree
__ia64__ really really should not be defined in the x86 arch subtree,
so remove it from xen/include/public/arch-x86/hvm/save.h

This in turn allows the removal of VIOAPIC_IS_IOSAPIC, as x86 does not
use streamlined {IO,L}APICs, allowing for the removal of more code
from the x86 tree.

Changes since v2:
 *  Leave the EOI register write protected by VIOAPIC_VERSION_ID >=
    0x20.  Currently, only version 0x11 is emulated, but leave this
    correct code in place in case a decision is make to emulate the
    newer version.

Changes since v1:
 *  Refresh patch following the decision not to try emulating a
    version 0x20 IOAPIC

we are only interested in knowing whether the line contains "initrd=",
but we don't care about it's position. Also fixes an error that
happens when initrd= it's at the start of the line, since find returns
0 and is evaluated as False.

Ian Campbell 9faa8b12d8 xl: use json output by default
Move the sxp producing code off into a separate file. It is supported
for legacy reasons and needn't be updated other than the improve
compatibility with xm.

libxl_domain_config is not currently generated by the IDL (adding the
necessary support for Array types is on my to do list) so hand code
the json generation function for now.

Since this rather directly exposes a libxl data structure it's not
clear what sort of forward compatibility guarantees we can
make. However it seems like it should be as stable as libxl's own API
(which we are looking to stabilise)

(Gratuitous string.h include needed for memset in libxl_util.h)

Boris Ostrovsky 8cbb5278e0 x86/AMD: Add support for AMD's OSVW feature in guests.
In some cases guests should not provide workarounds for errata even when the
physical processor is affected. For example, because of erratum 400 on family
10h processors a Linux guest will read an MSR (resulting in VMEXIT) before
going to idle in order to avoid getting stuck in a non-C0 state. This is not
necessary: HLT and IO instructions are intercepted and therefore there is no
reason for erratum 400 workaround in the guest.

This patch allows us to present a guest with certain errata as fixed,
regardless of the state of actual hardware.

Andrew Cooper b9110b80ec IO-APIC: Reformat IO-APIC RTE debug info (v2)
Having the columns aligned makes for much easier reading.  Also remove
the commas which only add to visual clutter in combination with
spaces.

Furthermore, printing fewer characters makes it less likely that the
serial buffer will overflow resulting in loss of critical debugging
information.

Changes since v1:
 *  Format vector as hex rather than dec
 *  Contract some names
 *  destination mode uses 'L' or 'P' instead of full words
 *  trigger mode uses 'L' or 'E' instead of full words
 *  delivery mode uses short string instead of a number
