This patch defines a test_and_clear bitop for cpumask_t pointers. Also fixes "wrong pointer type" for type specific bitops by using &foo [0] instead of &foo.

There is a BUG_ON() at xen/arch/x86/physdev.c:169 which appears to be dependent upon guest behavior (should close event channel before un-mapping pirq), rather than on internal hypervisor state. In 2.6.18, this likely goes unnoticed because pci_device_shutdown() only calls all the driver shutdown routines. In newer kernels, however, it also calls pci_msi_shutdown() and pci_msix_shutdown(), which

We are currently initializing GIC irq properties (ITARGETSR, IPRIORITYR, and GICD_ICFGR) only in gic_route_irq, that is not called for guest interrupts at all. Move the initialization into a separate function (gic_set_irq_properties) and call it from gic_route_irq_to_guest. Changes in v2: - rebased on 77d3a1db3196b1b5864469f8d3f41d496800c795.

Just been doing some simple phrases for Phoenix Online, uploaded the samples in q1 & q3 vorbis- when i click on the links in Mozilla, it opens the file in the window, displaying the files as text. How could i change the html file i've linked them on so that when people click on the links, this won't happen? http://galileo.spaceports.com/~djdij/po/index.html code that works in Mozilla

Patch 1 removes CONFIG_SMP Patch 2 removes separate smp_{,r,w}mb()s as a result of patch 1 Patch 4 removes __ia64__ defines from the x86 arch tree Patch 3 is related to patch 4 and changes the VIOAPIC to emulate version 0x20 as a performance gain. It preceeds Patch 4 so as to be more clear about the functional change. Signed-off-by: Andrew Cooper <andrew.cooper3@citrix.com>

Since IRQ probing may touch all currently unused interrupts, we must prevent probing for those where it doesn''t make sense (to avoid triggering BUG()s or de-referencing NULL function pointers): - dynamic IRQs must never be probed - physical IRQs should only be probed when registered or identity-mapped I haven''t got feedback from the reporting party, yet, but as the change seems

OK, I need to do something like this to io_apic.c - split the hardware specific parts out under mach-default, so we can override them for other subarchitectures. It's not finished, needs header file and makefile work. Would you be willing to take this if I do it? I'm not going to bother if you're not, such refactorings are a pig to maintain out of tree.

There has been some progress, but still no joy. Definitely not intended for inclusion at this point. Tim, Wei, I added a Xen command line toggle to disable IOMMU and P2M table sharing. Tim, I verified that changes to p2m-pt.c don''t break shadow mode (64bit hypervisor and Win 7 guest). Hongkaixing, I incorporated your suggestion in patch 2, so I should add your Signed-off-by eventually.
