Hi guys,
I finally got time to look at this issue. I think this series should fix
the problems that have been seen. I've tested this fairly thoroughly
with a qemu
This allows kdump kernels to be booted with low values for nr_cpu_ids
to conserve memory, while also allowing the crashing/boot CPU to be
any CPU.

Factor out the for loop that assigns CPU numbers to threads of a core.
The function takes the next CPU number to use as input, and returns the
next available CPU number after the threads has been assigned.
This will allow a subsequent change to assign threads out of order.

cross compilers (which use linux-).
This allows cross compiling with simply:
# Ubuntu
$ sudo apt install gcc-powerpc-linux-gnu
# Fedora
$ sudo dnf install gcc-powerpc64-linux-gnu
$ make ARCH=powerpc defconfig
$ make ARCH=powerpc -j 4
Inspired by arch/parisc/Makefile.

The vdso Makefile adds -U$(ARCH) to CPPFLAGS for the vdso64.lds linker
script. ARCH is always powerpc, so it becomes -Upowerpc, which means
undefine the "powerpc" symbol.
But the 64-bit compiler doesn't define powerpc in the first place,
compare:
$ gcc-5.1.0-nolibc/powerpc64-linux/bin/powerpc64
601 - 700 of 7380 matches
