The kernel team usually recommends 'make deb-pkg', and some of us work
on the scripts for that upstream.

They should both be using 'make' i.e. the default target.

The upstream default for CONFIG_KERNEL_START on powerpc is 0xc0000000.
The 'deb-pkg' scripts don't make any changes to the kernel config.
Please explain exactly how you are building the kernel with a
different entry point (config changes and commands).
