[PATCH] Unified shutdown code
...from EARLY_FAIL. This will facilitate the use of
Intel(R) TXT for measured launch by ensuring that all shutdowns will
call the necessary hook to tear down the measured environment. It also
centralizes any future shutdown-related changes.
The patch also postpones clearing the online status APs in
stop_this_cpu() until just before putting them into the hlt loop. This
ensures that when machine_teardown() checks that all APs have finished
their shutdown, that they have really have completed all interesting
tasks.
This applies to the staging tree as of today.

[PATCH 2/4] x86/hpet: replace disabling of legacy broadcast
... by the call to hpet_disable() added in the immediately preceding
patch.
In order to retain the behavior intended by c/s 23776:0ddb4481f883,
implement one of the alternative options pointed out there: remove CPUs
from the online map in __stop_this_cpu() (and hence doing so in
stop_this_cpu() is no longer needed).

[PATCH] hvm: clear vmxe if vmxoff
hvm: clear vmxe if vmxoff
The current Xen code keeps X86_CR4_VMXE set even if VMXON has not been
executed. The stop_vmx() code assumes that it is possible to call VMXOFF
if X86_CR4_VMXE is set which is not always true. Calling VMXOFF without
VMXON results in an illegal opcode trap, and to avoid this condition this
patch makes sure that X86_CR4_VMXE is only set when VMXON has been called.

Dual T400P, SMP, performance issues
Hi,
We are trying to validate Asterisk as a media gateway PRI <-> SIP with two
T400P (8 T1s) per box. The first
experience with BOX1 (Compaq, 2.53 GHz, 1 Gb RAM) and just one T400P was
encouraging - on the load
test with 3 T1s worth of calls we had on average 75% idle CPU.
Not so with BOX2 (Dell, single 2.6 GHz Xeon, 1 Gb RAM, 2 T400P) and BOX3
(Dell, dual 2.6 GHz Xeon,
2 Gb RAM, 2 T400P,
