Hi Andrew, This patch series adds to the end of the existing i386-gdt-cleanups patches: allow-per-cpu-variables-to-be-page-aligned.patch i386-gdt-cleanups-use-per-cpu-variables-for-gdt-pda.patch i386-gdt-cleanups-use-per-cpu-gdt-immediately-upon-boot.patch i386-gdt-cleanups-use-per-cpu-gdt-immediately-upon-boot-fix.patch i386-gdt-cleanups-clean-up-cpu_init.patch

Hi Andi, This is a series of patches based on your latest queue (as of the other day, at least). It includes: - the most recent patch to compute the appropriate amount of percpu space to allocate, using a separate reservation for modules where needed. - make the percpu sections page-aligned, so that percpu variables can be page aligned if needed (which is used by gdt_page) -

OK, here it is. Benchmarks still coming. This is against Andi's 2.6.18-rc7-git3 tree, and replaces the patches between (and not including) i386-pda-asm-offsets and i386-early-fault. One patch is identical, one is mildly modified, the rest are re-implemented but inspired by Jeremy's PDA work. Thanks, Rusty. -- Help!

Hi, Anyone has this working? Looks like there is a chicken-and-egg issue with pda setup: * xen_load_gdt() uses multicalls, thus depends on cpu-specific variables (per-cpu mc buffer) which in turn requires pda being setup already. * pda setup can't be done before xen_load_gdt() ... Next question while looking at xen_load_gdt(): why does it use multicalls in the first place?

Hi all, I've been looking at finding common ground between the VMI, Xen and other paravirtualization approaches, and after some discussion, we're getting somewhere. These first two patches are the fundamentals, stolen mainly from the VMI patches: removing assumptions about the kernel running in ring 0, and macro-izing all the obvious para-virtualize-needing insns. The third patch is

Hi, this is a series of patches that unify the struct desc_struct and friends across x86_64 and i386. As usual, it provides paravirt capabilities as a side-effect for x86_64. I consider the main goal, namely, of unifying the desc_struct, an ongoing effort, being this the beginning. A lot of old code has to be touched to accomplish that. I don't consider this patch ready for inclusion.

As suggested by Andi Kleen, don't allocate a GDT page if there is already one present. Needed for CPU hotplug.
