      x86/efi: Load fixmap GDT in efi_call_phys_epilog() · eeb89e2b
      Joerg Roedel authored
      When PTI is enabled on x86-32 the kernel uses the GDT mapped in the fixmap
      for the simple reason that this address is also mapped for user-space.
      
      The efi_call_phys_prolog()/efi_call_phys_epilog() wrappers change the GDT
      to call EFI runtime services and switch back to the kernel GDT when they
      return. But the switch-back uses the writable GDT, not the fixmap GDT.
      
      When that happened and and the CPU returns to user-space it switches to the
      user %cr3 and tries to restore user segment registers. This fails because
      the writable GDT is not mapped in the user page-table, and without a GDT
      the fault handlers also can't be launched. The result is a triple fault and
      reboot of the machine.
      
      Fix that by restoring the GDT back to the fixmap GDT which is also mapped
      in the user page-table.

      x86/nmi: Fix NMI uaccess race against CR3 switching · 4012e77a
      Andy Lutomirski authored
      
      A NMI can hit in the middle of context switching or in the middle of
      switch_mm_irqs_off().  In either case, CR3 might not match current->mm,
      which could cause copy_from_user_nmi() and friends to read the wrong
      memory.
      
      Fix it by adding a new nmi_uaccess_okay() helper and checking it in
      copy_from_user_nmi() and in __copy_from_user_nmi()'s callers.

      the compiler check (for asm goto support) to the archprepare target so that
      it is only done when building code for the target.

      cpu/hotplug: Remove skip_onerr field from cpuhp_step structure · 6fb86d97
      Mukesh Ojha authored
      When notifiers were there, `skip_onerr` was used to avoid calling
      particular step startup/teardown callbacks in the CPU up/down rollback
      path, which made the hotplug asymmetric.
      
      As notifiers are gone now after the full state machine conversion, the
      `skip_onerr` field is no longer required.
      
      Remove it from the structure and its usage.

      arm64: mm: always enable CONFIG_HOLES_IN_ZONE · f52bb98f
      James Morse authored
      Commit 6d526ee2 ("arm64: mm: enable CONFIG_HOLES_IN_ZONE for NUMA")
      only enabled HOLES_IN_ZONE for NUMA systems because the NUMA code was
      choking on the missing zone for nomap pages. This problem doesn't just
      apply to NUMA systems.
      
      If the architecture doesn't set HAVE_ARCH_PFN_VALID, pfn_valid() will
      return true if the pfn is part of a valid sparsemem section.
      
      When working with multiple pages, the mm code uses pfn_valid_within()
      to test each page it uses within the sparsemem section is valid. On
      most systems memory comes in MAX_ORDER_NR_PAGES chunks which all
      have valid/initialised struct pages. In this case pfn_valid_within()
      is optimised out.
      
      Systems where this isn't true (e.g. due to nomap) should set
      HOLES_IN_ZONE and provide HAVE_ARCH_PFN_VALID so that mm tests each
      page as it works with it.
      
      Currently non-NUMA arm64 systems can't enable HOLES_IN_ZONE, leading to
      a VM_BUG_ON():

      m68k/mac: Use correct PMU response format · 0986b16a
      Finn Thain authored
      Now that the 68k Mac port has adopted the via-pmu driver, it must decode
      the PMU response accordingly otherwise the date and time will be wrong.
