[LINUX] Fix IRQ SMP affinity logic for event channels.
The logic now mimics native x86 behaviour: a request to change
affinity via /proc is held until the next interrupt on that
event channel. So /proc/irq/n/smp_affinity may not change
immediately!
Other notes:
1. CPU-specific interrupts silently ignore requests to change
affinity. For example, resched0, timer0, callfunc0, ...
2. Reading smp_affinity always returns a cpumask containing
a single cpu. An event channel can only be bound to a single
cpu at a time. Neither Xen nor XenLinux implement IRQ
balancing: requires a user-space balancing daemon.

Reset Cirrus device model `VRAM' whenever a VGA/SVGA mode switch occurs.
If you change the video resolution on a Windows XP guest such that it uses
fewer bytes of VRAM (either by using fewer bytes per pixel or by lowering the
resolution) then some window backgrounds will become corrupted. This happens
because the Windows XP Cirrus Logic driver assumes that VRAM is initialized
to 0xff whenever the video mode switches between VGA and SVGA.
[HVM][DM] Cleaner way of clearing VGA memory on mode changes (thanks to
Fabrice Bellard on the QEMU project). This patch clears the
memory in the BIOS call rather than when the Cirrus Logic register changes,
which more closely matches what happens on the real hardware.

[XEND] Wait sufficient time for memory to balloon out before creating a new domain.
On the ES7000 when Dom0 boots up with all of system memory and you try
to bring up a DomU with more than 2GB of memory, xend times out before
the memory is freed causing the domain not to be created. This patch
increases the timeout depending on the amount of memory that needs to be
freed. It also places a cap on the sleep time so that it does not grow
without a limit. This fixes bug# 650
Fix IDE CD-drive PIO mode.
CD drives in PIO mode don't work under Xen because of a change in Linux
between 2.6.12 and 2.6.16, as a result of the following thread:
http://lists.parisc-linux.org/pipermail/parisc-linux/2005-August/027197.html
The change breaks systems which have highmem and a swiotlb because the
ide-cd driver doesn't use the swiotlb, resulting in read/writes to/from
highmem pages in PIO mode not working any longer. Xen kernels usually have
both highmem and a swiotlb.

SVM patch to add a host save area per core for the hypervisor and also

compatible with the vmcb layout, therefore will require it's own
"scratch pad". Consolidate the per core areas into a single structure. Signed-off-by: Tom Woller <thomas.woller@amd.com>

Prevent an oops in Dom0 that occurs when a CD device, specified as one
of the 'hardrives' in the 'disk=' line of a para-virtualized guest's
def file, has no media when the guest is started.
The oops occurs in vbd.c when vbd_size() is called from connect() (in
xenbus.c) and the vbd pointer is really an error code that comes from
the failed open that occurred in vbd_create().
build: Remove iptables and python loging helper targets
These targets don't really fit into the build infastructure,
for instance there is no faclilty for them to be removed
on make distclean. I posted a patch that fleshed out the targets,
but Christian Limpach suggested to me that removing them
would be a better idea.
In the case where XEN_PYTHON_NATIVE_INSTALL is in effect,
if DESTDIR is not set then the install will go into a relative
directory rather than under the default prefix (usually /usr).
An alternate solution would be to update the fragments
that do the python install to use 2062 2062 141 126DESTDIR)/ instead of
2062 2062 141 126DESTDIR). This is not an incredible burden as there
are only two such fragments in the tree. However, it
seems prone to error as new makefiles are created
in the future.
* Move .PHONY directives next to targets,
this makes them a lot harder to miss
* Add missing .PHONY directives
* Remove nonexistent .PHONY directives
* Hopefully I didn'T miss anything...
This fixes the Xen Makefile to allow correct building of cscope, TAGS
and tags. Prior to this the asm directory was not constructed correctly
for the "find" command. "xen\13cope.*" has been added to ".hgignore".
In some cases, say for instance for some bizzare reason
the tree was checked out of CVS, which doens't neccessarily
store file permissions, mkbuildtree may not be executable.
So run them explicitly via bash.

Fix an out-of-bounds memory access in xc_ptrace.c.
Currently, Xen always copies the entire 512 byte extended
FPU state (fxsave) even if only the "regular" FPU state was
requested.
This breaks since the memory buffer allocated in
linux-xen-low.c:regsets_fetch_inferior_registers() is only large
enough to hold the "plain" FPU registers.

Fix blkif and netif backend teardown -- do not remove devices from
sysfs (and hence trigger hotplug callbacks) until the devices really
are dead. This fixes a bug where the deferred code to free a blk
device was running concurrently with a hotplug-remove callback which
would try to reclaim the underlying storage. In some cases the race
would be lost and the hotplug script would fail.
Thanks to the Zhu Han at Intel for finding the root cause of this
long-term and annoying bug!
The current Xen code for VMX is setting the gp fault vmexiting in
the EXCEPTION_BITMAP vmcs control. There is no need for that as VMM is
just plainly re-injecting back to the guest. The attached is a simple
patch to set the vmcs control properly.

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.
