...symbols sitting within a 2Gb range on x86-64, they can be referred to by the kallsyms-like offset table using 4- instead of 8-byte slots. The marker table can use 4-byte slots in all cases, just like the table entry counts can (though that''s only a minor improvement). If ia64''s PERCPU_ADDR got moved down to (KERNEL_START + 2Gb - PERCPU_PAGE_SIZE), it could also utilize the more compact form.

Hi. This patchset implements ia64/pv_ops support which is the framework for virtualization support. Changes from take 5 are rebased to Linux 2.6.26-rc3, bug fix ivt.S paravirtualization and multi entry point support. I believe these patches can be applied to the linux ia64 repository. On x86 various ways to support virtualization were proposed, and eventually pv_ops won. So on ia64 the pv_ops

Hi. This patchset implements ia64/pv_ops support which is the framework for virtualization support. Now all the comments so far have been addressed, but only a few exceptions. On x86 various ways to support virtualization were proposed, and eventually pv_ops won. So on ia64 the pv_ops strategy is appropriate too. Later I'll post the patchset which implements xen domU based on ia64/pv_ops.

Hi. I rewrote the patch according to the comments. I adopted generating in-place code because it looks the quickest way. The point Eddie wanted to discuss is how to generate code and its ABI. i.e. in-place generating v.s. direct jump v.s. indirect function call Indirect function call doesn't make sense because ivt.S is compiled multi times. And it is up to pv instances to choose in-place

Hi. The patch I send before was too large so that it was dropped from the maling list. I'm sending again with smaller size. This patch set is the xen paravirtualization of hand written assenbly code. And I expect that much clean up is necessary before merge. We really need the feed back before starting actual clean up as Eddie already said before. Eddie discussed how to clean up and suggested

Hi. This patchset implements xen/ia64 domU support. Qing He and Eddie Dong also has been woring on pv_ops so that I want to discuss before going further and avoid duplicated work. I suppose that Eddie will also post his own patch. So reviewing both patches, we can reach to better pv_ops interface. - I didn't changed the ia64 intrinsic paravirtulization abi from the last post. Presumably it
