[PATCH V2 1/2] cpufreq, xenpm: fix cpufreq and xenpm mismatch
Currently cpufreq and xenpm are out of sync. Fix cpufreq reporting of
if turbo mode is enabled or not. Fix xenpm to not decode for tristate,
but a boolean.

It''s daft that we even have a CONFIG_SMP option in Xen. It spends most
of its time broken because no-one using x86 builds it, and you won''t
even be able to buy any non SMP hardware...

[PATCH 0 of 9] (v2) arm: SMP boot
This patch series implements SMP boot for arch/arm, as far as getting
all CPUs up and running the idle loop.
Changes from v1:
- moved barriers out of loop in udelay()
- dropped broken GIC change in favour of explanatory comment
- made the increment of ready_cpus atomic (I couldn''t move the
increment to before signalling the next CPU because the PT
switch has to happen between

[PATCH v5 0/7] Dissociate logical and gic/hardware CPU ID
Hi,
This is the fifth version of this patch series.
With the Versatile Express TC2, it''s possible to boot only with A7 or A15. If
the user choose to boot with only A7, the CPU ID will start at 0x100. As Xen
relies on it to set the logical ID and the GIC, it won''t be possible to use
Xen with this use case.
This patch series is divided in 3 parts:
- Patch 1: prepare Xen
