But early_identify_cpu() calls get_cpu_cap() which will check for cpuid leaf 0x80000008 support and set x86_phys_bits.
Right, but it can't be less than 32, can it? And if it is more than 32 bits, then it probably doesn't really matter on 32-bit. Unless it is less than 36 bits and you do PAE...
I'll try to build and run a 32-bit kernel and see how this all flows.
Yeah, that would be good.
Thanks.
