Is it possible to create git repository in git.kernel.org for Microblaze
cpu?
You need to ask the kernel.org administrators for that:

Thanks.
How many maintainers are acceptable? (one or more)
You can have as many maintainers as you want
Hi Sam,
It this code drop available somewhere?
the code is based on Petalogix kernel. I reduce huge Kconfig file to
necessary size. You'll see in patch or in web.
A brief information about this kernel is at http://www.monstr.eu/fdt/
I would like to review the Makefiles and to a lesser

Folks,
This new series is not at all fundamentally different from the old one
I sent. Only difference is that I address the comments received, mainly
from Rusty.
enjoy!

this patch introduces a vcpu struct for lguest. In upcoming patches,
more and more fields will be moved from the lguest struct to the vcpu

this patch initializes the first vcpu in the initialize() routing,
which is responsible for starting the process of putting the guest up.
right now, as much of the fields are still not per-vcpu, it does not
do much.

This patch makes the run_guest() routine use the vcpu struct.
This is required since in a smp guest environment, there's no
more the notion of running the guest, but rather, it is running the vcpu

This patch makes uses of pread() and pwrite() in lguest launcher
to communicate the vcpu id to the lguest driver. The id is kept in
a thread variable, which means we'll span in the future, vcpus as
threads. But right now, only the infrastructure is out there.

This patch makes the write() file operation smp aware. Which means, receiving
the vcpu_id value through the offset parameter, and being well aware to which
vcpu we're talking to.

Here, I introduce per-vcpu timers. With this, we can have
local expiries, needed for accounting time in smp guests

this patch changes do_hcall() and do_async_hcall() interfaces (and obviously
their
callers) to get a vcpu struct. Again, a vcpu services the hypercall, not the
whole

The switcher needs to be mapped per-vcpu, because different vcpus
will potentially have different page tables (they don't have to,
because threads will share the same).
So our first step is the make the function receive a vcpu struct

emulate_insn() needs to know about current eip, which will be,
in the future, a per-vcpu thing. So in this patch, the function
prototype is modified to receive a vcpu struct

The fields found in lguest_arch are not really per-guest,
but per-cpu (gdt, idt, etc). So this patch turns lguest_arch
into lg_vcpu_arch.
It makes sense to have a per-guest per-arch struct, but this
can be addressed later, when the need arrives.

This is the most obvious per-vcpu field: registers.
So this patch moves it from struct lguest to struct vcpu,
and patch the places in which they are used, accordingly

lguest uses tasks to control its running behaviour (like sending
breaks, controlling halted state, etc). In a per-vcpu environment,
each vcpu will have its own underlying task. So this patch
makes the infrastructure for that possible

lguest struct have room for some fields, namely, cr2, ts, esp1
and ss1, that are not really guest-wide, but rather, vcpu-wide.
This patch puts it in the vcpu struct

this patch makes the pgdir management per-vcpu. The pgdirs pool
is still guest-wide (although it'll probably need to grow when we
are really executing more vcpus), but the pgdidx index is gone,
since it makes no sense anymore. Instead, we use a per-vcpu
index.
