Move the source of lib/Kconfig.debug and arch/$(ARCH)/Kconfig.debug to the top-level Kconfig. For two architectures that means moving their arch-specific symbols in that menu into a new arch Kconfig.debug file, and for a few more creating a dummy file so that we can include it unconditionally. Also move the actual 'Kernel hacking' menu to lib/Kconfig.debug, where it belongs. Signed-off-by: Christoph Hellwig <hch@lst.de> Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>

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.
