panic in e100_exec_cb()
With today''s build, my domain 0 crashes during boot when it tries to
bring eth0 up (it''s an E100).
cb->prev (eax) is NULL in e100_exec_cb() (e100.c:827). Just from code
inspection, I don''t see how this can be. e100_alloc_cbs() was just
called, which looks like it should have correctly linked up all the
cb->prev/cb->next pointers.
It happens regardless of

[PATCH v3 0/9] x86: Concurrent TLB flushes
[ Cover-letter is identical to v2, including benchmark results,
excluding the change log. ]
Currently, local and remote TLB flushes are not performed concurrently,
which introduces unnecessary overhead - each INVLPG can take 100s of
cycles. This patch-set allows TLB flushes to be run concurrently: first
request the remote CPUs to initiate the flush, then run it locally, and
finally wait for

[patch 00/17] paravirt_ops updates
Hi Andi,
This series of patches updates paravirt_ops in various ways. Some of the
changes are plain cleanups and improvements, and some add some interfaces
necessary for Xen.
The brief overview:
add-MAINTAINERS.patch - obvious
remove-CONFIG_DEBUG_PARAVIRT.patch - no longer needed
paravirt-nop.patch - mark nop operations consistently
paravirt-pte-accessors.patch - operations to pack/unpack

[patch 00/20] paravirt_ops updates
Hi Andi,
Here's a repost of the paravirt_ops update series I posted the other day.
Since then, I found a few potential bugs with patching clobbering,
cleaned up and documented paravirt.h and the patching machinery.
Overview:
add-MAINTAINERS.patch
obvious
remove-CONFIG_DEBUG_PARAVIRT.patch
No longer meaningful or needed.

[patch 00/34] Xen-pv_ops: Xen guest implementation for paravirt_ops interface
Hi Andi,
This patch series implements the Linux Xen guest as a paravirt_ops
backend. The features in implemented this patch series are:
* domU only
* UP and SMP guest support (NEW!)
* dynamic ticks (NEW!)
* writable pagetables, with late pinning/early unpinning
(no shadow pagetable support)
* supports both PAE and non-PAE modes
(non-PAE may be broken at the moment)
* xen hvc console
