Elixir Linux Kernel: powerpc version of PAGE_OFFSET, KERNELBASE, LOAD_OFFSET, ...

[chleroy]

Macros PAGE_OFFSET, KERNELBASE, LOAD_OFFSET defined in arch/powerpc/include/asm/page.h (and probably others) are not seen as macros for powerpc.

https://elixir.bootlin.com/linux/v6.16/A/ident/LOAD_OFFSET
https://elixir.bootlin.com/linux/v6.16/A/ident/KERNELBASE

Looks more or less similar to #278 . By the way the problem is still there as well for that one, see https://elixir.bootlin.com/linux/v6.16/A/ident/__WARN_FLAGS
