Merge tag 'x86-urgent-2024-08-11' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull x86 fixes from Thomas Gleixner: - Fix 32-bit PTI for real. pti_clone_entry_text() is called twice, once before initcalls so that initcalls can use the user-mode helper and then again after text is set read only. Setting read only on 32-bit might break up the PMD mapping, which makes the second invocation of pti_clone_entry_text() find the mappings out of sync and failing. Allow the second call to split the existing PMDs in the user mapping and synchronize with the kernel mapping. - Don't make acpi_mp_wake_mailbox read-only after init as the mail box must be writable in the case that CPU hotplug operations happen after boot. Otherwise the attempt to start a CPU crashes with a write to read only memory. - Add a missing sanity check in mtrr_save_state() to ensure that the fixed MTRR MSRs are supported. Otherwise mtrr_save_state() ends up in a #GP, which is fixed up, but the WARN_ON() can bring systems down when panic on warn is set. * tag 'x86-urgent-2024-08-11' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: x86/mtrr: Check if fixed MTRRs exist before saving them x86/paravirt: Fix incorrect virt spinlock setting on bare metal x86/acpi: Remove __ro_after_init from acpi_mp_wake_mailbox x86/mm: Fix PTI for i386 some more
