| 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. |

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

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