Fix the polling section of the hvc driver to use the global "last_hvc" variable, rather than the ttys.

Before I get to entrenched in the ACPI code - I thought I''d ping the community to make sure nobody else has investigated this already - Can we present cores vs sockets for guest VCPUs? Right now, the number of total processors can be specified, but can we specify cores per socket? I see this potentially being an hvmloader function, as part of its acpi build code. Could this be

Intercept guest reads of MSR_IA32_MCG_CAP and limit the number of memory banks reported to one. This prevents us from trying to read status of non-existent banks when migrated to a machine with fewer banks.

Jan, I was given a machine to diagnose a boot problem on xen 4.3, that used to work on 4.2, and have bisected to the following changeset: commit d0d4635d034f202bb401a6efa3ba61530f3854ab Author: Jan Beulich <jbeulich@suse.com> Date: Thu Nov 22 10:47:58 2012 +0100 implement vmap() ... and use it as basis for a proper ioremap() on x86.

Jan (or others), I'm seeing an issue with the EHCI debug port functionality, that I'm wondering whether it is a known limitation of the hardware, or if this is a bug. On a particular system that I had limited debug capabilities in the past (Dell Inspiron 15 i3) I am seeing the debug messages abruptly stop during boot, followed by garbage that looks like an uninitialized serial port:

...ldconfigs/linux-defconfig_xen_x86_32;style=rev%3D%2B%2509buildconfigs%252Flinux My question is - If this was intentionally pulled out of the buildconfig - what am I doing wrong? Alternately If this was an unintended result of the merge - would you accept a simple patch to fix this?

...nt into the 3.1.1 staging tree today. Does this mean that we should expect a 4th release candidate before the 3.1.1 release tag is official? If so - how much testing time are you going to give that release candidate before deciding whether a release tag, or another RC round is appropriate?

Hi Guys, Thanks for the interest in the xen hypervisor debugger, prev known as kdb. Btw. I''m gonna rename it to xdb for xen-debugger or hdb for hypervisor debugger. KDB is confusing people with linux kdb debugger and I often get emails where people think they need to apply linux kdb patch also... Anyways, attaching patch that is cleaned up of my debug code that I accidentally left in
