Subject: [GIT PULL] (xen) stable/for-linus-3.7-x86-tag
Hey Linus,
Please git pull the following tag:
git://git.kernel.org/pub/scm/linux/kernel/git/konrad/xen.git stable/for-linus-3.7-x86-tag
which as features/fixes for the x86 and the generic side of the Xen tree.
The signed tag has the wealth of details of what it contains, so I am copying
it here:
<signed tag>
Features:
* When hotplugging PCI devices in a PV guest we can allocate Xen-SWIOTLB later.
* Cleanup Xen SWIOTLB.
* Support pages out grants from HVM domains in the backends.
* Support wild cards in xen-pciback.hide=(BDF) arguments.
* Update grant status updates with upstream hypervisor.
* Boot PV guests with more than 128GB.
* Cleanup Xen MMU code/add comments.
* Obtain XENVERS using a preferred method.
* Lay out generic changes to support Xen ARM.
* Allow privcmd ioctl for HVM (used to do only PV).
* Do v2 of mmap_batch for privcmd ioctls.
* If hypervisor saves the LED keyboard light - we will now instruct the kernel
about its state.
Fixes:
* More fixes to Xen PCI backend for various calls/FLR/etc.
* With more than 4GB in a 64-bit PV guest disable native SWIOTLB.
* Fix up smatch warnings.
* Fix up various return values in privmcmd and mm.
</signed tag>
It is rather a big pull - and some of them are architecture specific to prep
for the Xen ARM patches.
The 1-2 line changes are additions of #include files to support compilation
under ARM.
There are also changes to SWIOTLB - to allow it to be used later in
the boot process (so we can hotplug PCI devices and allocate SWIOTLB in case
we hadn't started it). IA64 does this too - so the patches expand the existing
function - and have been tested with success on IA64 to make sure they do not
introduce regressions.
Please pull!
