[Xen-devel] Features and bug fixes for Linux kernel 3.2.

Hey,

Please keep in mind that there is some outstanding work going on which
could make it in 3.2 depending on when the merge window opens. I will
enumerate those in the next email.

Anyhow, for 3.2 Linux kernel we have these items loaded and ready to go:

 - A new mechanism to parse the E820 resulting in better ballooning.
 - hwclock support. Meaning you can do ''date XX'' and it will
be saved by machine.
 - Support for PCI multi-segmented machines (big big iron boxes)
 - Optimizations in DMA API.
 - "feature-barrier" in the xen-blkback so that older kernels (SLES10)
   can issue those.
 - "feature-discard" so that TRIM/SCSI UNMAP operations can be
utilized.
 - kexec/kdump support for PVonHVM.
 - Cleanups in the code (mostly scripts/cleanpatch.pl)
 - Static analyzer (smatch) run results fixing bugs.
 - Tons of bug fixes.

If you think I missed something - please please email me immediately.


The list is as follow.

Dan Carpenter (1):
      xen/pciback: double lock typo

David Vrabel (9):
      xen/balloon: account for pages released during memory setup
      xen/balloon: simplify test for the end of usable RAM
      xen: allow balloon driver to use more than one memory region
      xen: allow extra memory to be in multiple regions
      xen: release all pages within 1-1 p2m mappings
      xen: use generic functions instead of xen_{alloc, free}_vm_area()
      block: xen-blkback: use API provided by xenbus module to map rings
      net: xen-netback: use API provided by xenbus module to map rings
      xen: map foreign pages for shared rings by updating the PTEs directly

Jan Beulich (5):
      xen/pci: make bus notifier handler return sane values

      xen/blkback: Support ''feature-barrier'' aka old-style
BARRIER requests.
      xen/blkback: Report VBD_WSECT (wr_sect) properly.

Have You meant ^^^ "x86/paravirt: PTE updates in k(un)map_atomic need to be
synchronous, regardless of lazy_mmu mode" there?

Ah, yes, and I believe that patch is actually carried by Andrew Morton,
so let me drop it here.

Thanks for spotting that!

It''s more a precursor to a Xen thing but the ground work for SKB
fragment lifecycle tracking should be going in via the networking tree
in the next merge window.

That work will eventually lead to the reintroduction of the mapping mode
of guest network tx as opposed to the copy mode we have in upstream
right now. That''s more like 3.3 or 3.4 material though.

These are some extra ones I put in since yesterday:

Dan Magenheimer (1):
      xen: Fix selfballooning and ensure it doesn''t go too far

Daniel De Graaf (3):
      xenbus: Fix loopback event channel assuming domain 0
      xenbus: don''t rely on xen_initial_domain to detect local xenstore
      xen/gntdev: Fix sleep-inside-spinlock

Konrad Rzeszutek Wilk (1):
      xen/blkback: Check for proper operation.
