Remove the Kconfig selection of semaphore debugging from the ALPHA and FRV Kconfig files, and centralize it in lib/Kconfig.debug. There doesn't seem to be much point in letting individual architectures independently define the same Kconfig option when it can just as easily be put in a single Kconfig file and made dependent on a subset of architectures. that way, at least the option shows up in the same relative location in the menu each time.

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.

|
|
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.
