CONFIG_ALPHA_GAMMA
Say Y if you have an AS 2000 5/xxx or an AS 2100 5/xxx.
CONFIG_ALPHA_EV67
Is this a machine based on the EV67 core? If in doubt, select N here
and the machine will be treated as an EV6.
CONFIG_ALPHA_SRM
There are two different types of booting firmware on Alphas: SRM,
which is command line driven, and ARC, which uses menus and arrow

best used in conjunction with the NMI watchdog so that spinlock
deadlocks are also debuggable.
CONFIG_DEBUG_RWLOCK
If you say Y here then read-write lock processing will count how many
times it has tried to get the lock and issue an error message after
too many attempts. If you suspect a rwlock problem or a kernel
hacker asks for this option then say Y. Otherwise say N.
CONFIG_DEBUG_SEMAPHORE
If you say Y here then semaphore processing will issue lots of
verbose debugging messages. If you suspect a semaphore problem or a
kernel hacker asks for this option then say Y. Otherwise say N.
