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/pciback: use mutex rather than spinlock in passthrough backend
xen/pciback: miscellaneous adjustments
xen/pci: support multi-segment systems
xen-blkback: use kzalloc() in favor of kmalloc()+memset()
Jeremy Fitzhardinge (2):
xen: add dom0_op hypercall
xen/dom0: set wallclock time in Xen
Joe Jin (1):
xen-blkback: fixed indentation and comments
Konrad Rzeszutek Wilk (24):
Revert "xen/debug: WARN_ON when identity PFN has no _PAGE_IOMAP flag
set."
xen-pcifront: Update warning comment to use 'e820_host' option.

xen/p2m: Use SetPagePrivate and its friends for M2P overrides.
x86/paravirt: Partially revert "remove lazy mode in interrupts"
Have You meant ^^^ "x86/paravirt: PTE updates in k(un)map_atomic need to be
synchronous, regardless of lazy_mmu mode" there?
xen/pv-on-hvm:kexec: Fix implicit declaration of function
'xen_hvm_domain'
xen/pciback: Do not dereference psdev during printk when it is NULL.
xen-blkfront: If no barrier or flush is supported, use invalid operation.
xen/blkback: Support 'feature-barrier' aka old-style BARRIER requests.
xen/blkback: Report VBD_WSECT (wr_sect) properly.
xen/blkback: Fix the inhibition to map pages when discarding sector
ranges.
xen/pciback: Check if the device is found instead of blindly assuming so.
xen/events: BUG() when we can't allocate our event->irq array.
xen/events: Don't check the info for NULL as it is already done.
xen/irq: If we fail during msi_capability_init return proper error code.
xen/xenbus: Remove the unnecessary check.
xen/enlighten: Fix compile warnings and set cx to known value.
xen/p2m/debugfs: Fix potential pointer exception.
xen/p2m/debugfs: Make type_name more obvious.
Laszlo Ersek (1):

events arrive
