x86: APIC: enable workaround on AMD Fam10h CPUs
Impact: fix to enable APIC for AMD Fam10h on chipsets with a missing/b0rked ACPI MP table (MADT) Booting a 32bit kernel on an AMD Fam10h CPU running on chipsets with missing/b0rked MP table leads to a hang pretty early in the boot process due to the APIC not being initialized. Fix that by falling back to the default APIC base address in 32bit code, as it is done in the 64bit codepath. Signed-off-by: Borislav Petkov <borislav.petkov@amd.com> Signed-off-by: H.
