Subject: [patch 00/33] xen: Xen paravirt_ops implementation
Hi,
This is the Xen implementation for the paravirt_ops interface. The
series is based on 2.6.22-rc1-mm1, and I think its ready to be cooked
in -mm with a view to being merged in 2.6.23.
The first part of the series is some small changes to the core kernel.
Apart from the new code added in "Allocate and free vmalloc areas"
(posted many times before), they are simply a few one-liners around
the place.
paravirt: add an "mm" argument to alloc_pt
paravirt: add a hook for once the allocator is ready
paravirt: increase IRQ limit
paravirt: unstatic leave_mm
paravirt: unstatic smp_store_cpu_info
paravirt: make siblingmap functions visible
paravirt: export __supported_pte_mask
xen: Allocate and free vmalloc areas

The rest of the series is the Xen implementation itself. This
includes the core of Xen itself, plus the Xenbus virtual bus, and
virtual console, disk and net drivers. The vast majority of it is new
code, with a few changes to non-Xen files to:
1. Makefile/Kconfig build stuff
2. add a new ELF note to the VDSO to select a Xen-optimised libc
3. a chunk of new code in entry.S, to handle upcalls from Xen,
which in turn need to jump into other entry.S labels
4. Define a proper label for PG_owner_priv_1
5. Define a major for the Xen virtual block device
6. Increate NR_IRQ to 224 when CONFIG_PARAVIRT is enabled, even if
there's no IO APIC.
