…hout cmdline

…n to build a fake bcmdhd driver

in order to solve sense4 wifi tethering, i build a fake bcmdhd driver
based on bcm4329_248 driver, with userland support

The only changes i made is for gpu32/2d oc control, works without cmdline/badass

…cate code

Since the sched_domain walk is completely unserialized (!SD_SERIALIZE)
it is possible that multiple cpus in the group get elected to do the
next level. Avoid this by adding some serialization.

zram compiled as module
disable frontswap compilation parameter, no need of it
while there is no real swap on sensation.

first try to have zcache, cleancache and frontswap functional
Made zram compiled as module (need modified /system/etc/init.d/90zam
to have it working)

I discovered this deadlock condition awhile ago working on RAMster
but it affects zcache as well.  The list spinlock must be
locked prior to the page spinlock and released after.  As
a result, the page copy must also be done while the locks are held.

Applies to 3.2.  Konrad, please push (via GregKH?)...
this is definitely a bug fix so need not be pushed during
a -rc0 window.
