Merge tag 'x86_urgent_for_v6.12_rc5' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull x86 fixes from Borislav Petkov:
- Prevent a certain range of pages which get marked as hypervisor-only,
to get allocated to a CoCo (SNP) guest which cannot use them and thus
fail booting
- Fix the microcode loader on AMD to pay attention to the stepping of a
patch and to handle the case where a BIOS config option splits the
machine into logical NUMA nodes per L3 cache slice
- Disable LAM from being built by default due to security concerns
