202333c881 hw: cortex a9 diagnostic register initialization 
We cannot count on the correct initialization of the diagnostic register
of the secondary cores. But the boot core gets initialized by the bootchain,
so we can copy over those values.

beb8bf498c base-hw: add explicit array-bounds check 
This patch rules out out-of-bounds array accesses without inspecting the
caller. It is not a bug fix but adds clarity.

d417d26ce8 hw: fix calculation of CPU count on x86_64 
On x86 the CPU count is determined through ACPI's MADT by counting the
local APICs reported there. Some platforms report more APICs
than there are actual CPUs. These might be physically disabled CPUs.
Therefore, a check if the LAPIC is actually physically enabled in
hardware fixes this issue.

Thanks to Alex Boettcher
