Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!

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.

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.

---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.
