bitfield we can use 1MB sections without having weird interference between

Xeon Phi boot: getting rid of the single boot image and dependencies
Adapting the boot protocol of the Xeon Phi cards to dynamically
load the individual modules at run time rather than compile time.
The following sources can be used to load the modules
- in ramfs of host machine
- from a TFTP server (using the --tftp flag)
- from NFS (using the --nfs flag)
The modules to be loaded are specified in a supplied menu.lst file.
The parameter --modlist can be used to specify that file.
The boot driver will handle the generation of the needed data structures
and headers when the card boots.

Revert b51b15e e7b3175. Closes T88 T96.
mutex_lock und unlock was correct in its original implementation:
lock will put a thread in the mutex queue in case some thread already
has the mutex locked, and mutex_unlock is guaranteed to wake-up one of the
waiting threads by taking it from mutex->queue. mutex->locked will
remain set to 1 in case we wakeup a thread from unlock() and access to
the mutex structure is always protected by the mutex->lock spinlock.

Fix b51b15e: re-disable dispatcher in thread_mutex_lock* and thread_sem_wait().
Re-disable dispatcher after returning from
thread_block_and_release_spinlock_disabled() and also fix thread_sem_wait() to
correctly block until semaphore can be acquired.
