13	help
14	  If you say Y here then read-write lock processing will count how many
15	  times it has tried to get the lock and issue an error message after
16	  too many attempts.  If you suspect a rwlock problem or a kernel
17	  hacker asks for this option then say Y.  Otherwise say N.

22	help
23	  If you say Y here then semaphore processing will issue lots of
24	  verbose debugging messages.  If you suspect a semaphore problem or a
25	  kernel hacker asks for this option then say Y.  Otherwise say N.

30	default n
31	---help---
32	  The 2.4 kernel changed the kernel start address from 0x310000
33	  to 0x810000 to make room for the Wildfire's larger SRM console.
34	  Recent consoles on Titan and Marvel machines also require the
35	  extra room.
36
37	  If you're using aboot 0.7 or later, the bootloader will examine the
38	  ELF headers to determine where to transfer control. Unfortunately,
39	  most older bootloaders -- APB or MILO -- hardcoded the kernel start
40	  address rather than examining the ELF headers, and the result is a
41	  hard lockup.
42
43	  Say Y if you have a broken bootloader.  Say N if you do not, or if
44	  you wish to run on Wildfire, Titan, or Marvel.

54	help
55	  This option is required for IEEE compliant floating point arithmetic
56	  on the Alpha. The only time you would ever not say Y is to say M in
57	  order to debug the code. Say Y unless you know what you are doing.
