2.Allocate siginfo arrary separately to avoid pthread to be allocated at
2K boundary, which hits L1 address alias problem and causes context
switch to be slow down.
3.Simplify context switch code by removing redundant code, code size is
reduced, so it is expected to run faster.

o fix race condition when processing rx descriptors: because we use
a self-linked descriptor at the end of the rx descriptor list to
avoid rx overruns (which can easily happen for 5212 parts that enable
PHY errors) we must carefully check that a descriptor is "done" by
looking ahead to the next descriptor before believing the done bit
in the current descriptor (this is all handled in the HAL since the
rx descriptor format is chip-specific so we need to pass in two
additional parameters--the physical address of the current descriptor
and the virtual address of the next descriptor in the list)

selection is used to drive two configuration parameters:
(1) Default enable/disable for sshd
(2) Default enable/disable for securelevels
Replace this with an explicit choice to enable/disable sshd. A
follow-up commit will add a configuration option to the Security
post-install configuration menu to set the securelevel in rc.conf
explicitly. This should reduce the level of foot-shooting associated
with accidental enabling of securelevels, make the nature and
implications of the securelevel configuration options more explicit,
as well as make the choice to enable/disable sshd more explicit.

initialization overhead, there's a problem in that we never call
imalloc() and thus malloc_init() for zero-sized allocations. As a
result, malloc(0) returns NULL when it's the first or only malloc in
the program. Any non-zero allocation will initialize the malloc code
with the side-effect that subsequent zero-sized allocations return a
non-NULL pointer. This is because the pointer we return for zero-
sized allocations is calculated from malloc_pageshift, which needs
to be initialized at runtime on ia64.
The result of the inconsistent behaviour described above is that
configure scripts failed the test for a GNU compatible malloc. This
resulted in a lot of broken ports.
Other, even simpler, solutions were possible as well:
1. initialize malloc_pageshift with some non-zero value (say 13 for
8KB pages) and keep the runtime adjustment.
2. Stop using malloc_pageshift to calculate ZEROSIZEPTR.
Removal of the runtime adjustment was chosen because then ia64 is the
same as any other platform. It is not to say that using a page size
obtained at runtime is bad per se. It's that there's currently a high
level of gratuity for its existence and the moment it causes problems
is the moment you need to get rid of it. Hence, it's not unthinkable
that this commit is (partially) reverted some time in the future when
we do have a good reason for it and a good way to achieve it.

does not match that processor's pc_acpi_id, return the value for
ProcId derived from the MADT in *acpi_id. If pc_acpi_id is 0xffffffff,
always override it with the value of *acpi_id. Finally, return
pc_cpuid in *cpu_id and use that as our primary key.
* Use pc_cpuid as our unique key because we know it is valid since
MD code set it. The values for ProcId in the ASL and MADT don't
match up on some machines (!), forcing us to fall back to ordered
probing in that case.
* Remove some #ifdef SMP since the refcount doesn't hurt performance
