- 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.

- help
- 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.
