[Xen-devel] Features for Linux kernel 3.3.

[Konrad Rzeszutek Wilk <konrad.wilk@xxxxxxxxxx>]

This is what is being currently developed and reviewed. Some of it
might be done before 3.2 merge windows opens so it could become part
of 3.2:

 - PV spinlocks. Jeremy has been tirelessly working on this and every time
   it looks like it is ready somebody comes out and points out a bug
   in generic code that impacts his work. So this has mushroomed to now
   include jump_label support (for tracing), compare and exchange atomic
   operations (for everything), and then the PV spinlocks patches.

 - ACPI S3 support. The code is going through a review and we need
   some eyes from the ACPI folks to make sure nothing is wrong.

 - Graphic support for radeon/nouveau for 32-bit cards (enterprise type).
   Also known as "TTM DMA pool" code.

 - Blkback/blkfront features. Expanding the blkback to do amazing things.
   Like make the code easier to read, expanding the discard support to support
   REQ_DISCARD_SECURE and also do multipage rings (to allow more I/Os).

 - microcode update. Well, this one is complex. The x86 maintainers
   want to re-write how it is done, so the Xen microcode is shelved for
   right now until that is complete.

 - cleancache. This is the last piece of tmem - it allows the swap disk
   to use the temporary memory pool that tmem provides to make the guest
   run even faster.

 - Xen ACPI cpufreq patches. They are not yet ready to be posted, but they
   are slowly taking shape.

If I missed somebody's current work, please point me out to it.
