[IA64] Change vCPU initialization to avoid domVTi privregs memory leak
1) This patch moved some processing from vcpu_initialise() and
added a new function vcpu_late_initialise().
It executes the following initializations for VCPU of
dom0/domU.
- Allocate the VHPT
- Allocate the privregs area and assign these pages into
guest pseudo physical address space.
- Set the tlbflush_timestamp.
It is executed in the following sequence.
dom0:
start_kernel()
->domain_create()
->alloc_vcpu(VCPU0)
->alloc_vcpu_struct(VCPU0)
->vcpu_initialise(VCPU0)
->vcpu_late_initialise(VCPU0)
->construct_dom0
->alloc_vcpu(othe VCPUs)
->alloc_vcpu_struct(other VCPUs)
->vcpu_initialise(other VCPUs)
ia64_hypercall(FW_HYPERCALL_IPI)
->fw_hypercall_ipi(XEN_SAL_BOOT_RENDEZ_VEC)
->arch_set_info_guest(other VCPUs)
->vcpu_late_initialise(other VCPUs)
domU:
do_domctl(XEN_DOMCTL_createdomain)
->domain_create()
do_domctl(XEN_DOMCTL_max_vcpus)
->alloc_vcpu(all VCPUs)
->alloc_vcpu_struct(all VCPUs)
->vcpu_initialise(all VCPUs)

->fw_hypercall_ipi(XEN_SAL_BOOT_RENDEZ_VEC)
->arch_set_info_guest(other VCPUs)
->vcpu_late_initialise(other VCPUs)
2) This patch modified the domain_set_shared_info_va().
Currently, initialization of arch.privregs->interrupt_mask_addr
of all VCPUs is executed in domain_set_shared_info_va().
However, allocation of privregs area is late by modified of 1).
Therefore, this patch modified initialization of
arch.privregs->interrupt_mask_addr to the following sequence.
dom0 and domU:
ia64_hypercall(FW_HYPERCALL_SET_SHARED_INFO_VA)
->domain_set_shared_info_va()
Initialize interrupt_mask_addr of VCPU0
ia64_hypercall(FW_HYPERCALL_IPI)
->fw_hypercall_ipi(XEN_SAL_BOOT_RENDEZ_VEC)

[PATCH] kexec/kdump: allow zero start for crashkernel
Some architectures, notably ia64, can automatically place
the crash kernel into an appropriate place if the start
address for crashkernel is specified as zero or omitted.
E.g. crashkernel=256M or crashkernel=256M@0
While xen does not actually have support for ia64 kexec,
I am working on it. And in any case this change should be harmless.
Just a small bit of infastructure that will make things easier in the
future.
This should also be possible on x86, now relocatable kernels
are reloacatble on x86. So once xen moves up to using linux ~2.6.19
it would make sense to look into implementing this.
The patch does 3 things.
* Firstly, parse_crashkernel() is modified to allows the size and start elements of kexec_crash_area
to be set to any value, including zero. Previously if either size or
start were specified as zero, they would both end up as zero.
* Secondly, when kexec_get() is called, if either the size or start
elements of kexec_crash_area are zero, then zero is passed
back to the hypercall caller for both values.
This gives the same behaviour as having parse_crashkernel() set
size and start to zero if either of them are zero, but it allows
architecture sepcific code called between the invocation of
parse_crashkernel() and kexec_get() to modify start (and size if
there was a reason). In particular, this allows the
architecture specific code to find a good start point if 0 is
specified.
* Lastly, it ads an additional check to the x86 setup code.
As this code currently does not know how to deal with a
0 start address, it doesn't reserve memory if start is 0.
This is neccessary as previously if start was specified as zero,
parse_crashkernel() would set size to zero, but that is
no longer the case, so a stronger check is needed.
I would really appreciate it if this patch was merged,
as I don't believe it harms anything, and it does allow
a nice path for moving forwards.

[LINUX] ipv6: Disable addrconf on Xen bridge device
The ipv6-no-autoconf patch didn't disable IPv6 addrconf completely.
This means that the Xen bridge device still interfered with normal
IPv6 operation by engaging the IPv6 network with a bogus MAC address.
For details please refer to
https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=200360
The following patch completely disables IPv6 on the Xen bridge device
by temporarily setting the MTU to a value less than the minimum
allowed for IPv6.
Upstream will provide a cleaner way to disable IPv6 addrconf in
future, possibly in the form of a proc sysctl. Of course if the Xen
loopback device is removed it would render this change unnecessary.

http://lists.xensource.com/archives/html/xen-ia64-devel/2006-11/msg00349.html
The real VHPT insertion is done based on the machine PTE returned from
translate_domain_pte, which does the appropriate offset calculations.
However, the insertion into the one-entry TLB uses the original PTE, but
the page size has been reset to PAGE_SIZE [1]. Thus the entry in the
one-entry TLB incorrectly maps the PAGE_SIZE sub-page which was faulted
on to the PAGE_SIZE sub-page at the bottom of the superpage.
I think it makes most sense to simply use the original itir when
inserting into the single-entry TLB, as per attached patch. I've moved
the vcpu_set_tr_entry calls up a level into vcpu_itc_d and vcpu_itc_i;
the third caller previously used the 4 flag to specify "don't do that".

This patch makes the logic in setup_guest() more clear.

size and GFW memory to QEMU and Libxc. This patch fixes
