There's a lockup condition where kswapd ensounters an empty zone which has all
its metadata set to zero.

Fix that by adding explicit checks for empty zones and just skip over them.

This patch, based on Ken Chen's patch, changes the default 2.5 msec
migration-cutoff value to be based on cache_decay_ticks, which is what
we used for a long time prior the sched-domains code.  (If an
architecture does not set cache_decay_ticks then 2.5 msec is used.)

This causes the following new migration-cutoff values on various SMP
systems:

 x86, variable:

 2-way celeron 466MHz, 128K:        2.5 msec ->  1.0 msec
 2-way/4-way 2.2 GHz P4 Xeon 1MB:   2.5 msec ->  2.0 msec
 8-way P3 700 MHz Xeon 2MB:         2.5 msec ->  6.0 msec

 x64, variable:

 amd64: 2.0 GHz, 1MB:               2.5 msec -> 1.5 msec
 em64t: 3.4 GHz, 1MB:               2.5 msec -> 3.0 msec

 ppc64 [*]:                         2.5 msec -> 2.5 msec (constant)

 ia64:                              2.5 msec -> 10.0 msec (constant)

    [*] ppc64 does not set cache_decay_ticks so we fall back to the
        default.

I believe in light of previous testing we could attempt this for 2.6.9 as
well.  (Note: that the 2.6.9-rc3 patch looks similar but needs to patch
kernel/sched.c.  Note2: this patch is different from Ken's original one.)

The find_udbg_vterm() used to initialize the early boot console

used to identify firmware nodes. This patch fixes that by using

Arecent changeset[0] that changed params into an asm function call
broke the PXA build since PXA does not define PARAMS_PHYS therefore
the params_phys variable is never defined and linking arch/arm/boot/compressed/head.S fails.

The function is defined in include/asm-arm/arch-rpc/uncompress.h 
and so I assume it is dependendant on CONFIG_ARCH_RPC. I can't find 
any use of it outside this file.
