      x86: correct the conversion of EFI memory types · e2a71476
      Cliff Wickman authored
      This patch causes all the EFI_RESERVED_TYPE memory reservations to be recorded
      in the e820 table as type E820_RESERVED.
      
      (This patch replaces one called 'x86: vendor reserved memory type'.
       This version has been discussed a bit with Peter and Yinghai but not given
       a final opinion.)
      
      Without this patch EFI_RESERVED_TYPE memory reservations may be
      marked usable in the e820 table. There may be a collision between
      kernel use and some reserver's use of this memory.
      
      (An example use of this functionality is the UV system, which
       will access extremely large areas of memory with a memory engine
       that allows a user to address beyond the processor's range.  Such
       areas are reserved in the EFI table by the BIOS.
       Some loaders have a restricted number of entries possible in the e820 table,
       hence the need to record the reservations in the unrestricted EFI table.)
      
      The call to do_add_efi_memmap() is only made if "add_efi_memmap" is specified
      on the kernel command line.

      x86: cap iomem_resource to addressable physical memory · 95ee14e4
      H. Peter Anvin authored
      iomem_resource is by default initialized to -1, which means 64 bits of
      physical address space if 64-bit resources are enabled.  However, x86
      CPUs cannot address 64 bits of physical address space.  Thus, we want
      to cap the physical address space to what the union of all CPU can
      actually address.
      
      Without this patch, we may end up assigning inaccessible values to
      uninitialized 64-bit PCI memory resources.

      x86: mm: Read cr2 before prefetching the mmap_lock · 5dfaf90f
      Ingo Molnar authored
      Prefetch instructions can generate spurious faults on certain
      models of older CPUs. The faults themselves cannot be stopped
      and they can occur pretty much anywhere - so the way we solve
      them is that we detect certain patterns and ignore the fault.
      
      There is one small path of code where we must not take faults
      though: the #PF handler execution leading up to the reading
      of the CR2 (the faulting address). If we take a fault there
      then we destroy the CR2 value (with that of the prefetching
      instruction's) and possibly mishandle user-space or
      kernel-space pagefaults.
      
      It turns out that in current upstream we do exactly that:
      
      	prefetchw(&mm->mmap_sem);
      
      	/* Get the faulting address: */
      	address = read_cr2();
      
      This is not good.
      
      So turn around the order: first read the cr2 then prefetch
      the lock address. Reading cr2 is plenty fast (2 cycles) so
      delaying the prefetch by this amount shouldnt be a big issue
      performance-wise.
      
      [ And this might explain a mystery fault.c warning that sometimes
        occurs on one an old AMD/Semptron based test-system i have -
        which does have such prefetch problems. ]

      amd-iommu: resume cleanup · 6a047d8b
      Chris Wright authored
      Now that enable_iommus() will call iommu_disable() for each iommu,
      the call to disable_iommus() during resume is redundant.  Also, the order
      for an invalidation is to invalidate device table entries first, then
      domain translations.

      x86: hpet: Mark per cpu interrupts IRQF_TIMER to prevent resume failure · 507fa3a3
      Thomas Gleixner authored
      timer interrupts are excluded from being disabled during suspend. The
      clock events code manages the disabling of clock events on its own
      because the timer interrupt needs to be functional before the resume
      code reenables the device interrupts.
      
      The hpet per cpu timers request their interrupt without setting the
      IRQF_TIMER flag so suspend_device_irqs() disables them as well which
      results in a fatal resume failure on the boot CPU.
      
      Adding IRQF_TIMER to the interupt flags when requesting the hpet per
      cpu timer interrupts solves the problem.

      x86: handle initrd that extends into unusable memory · 8c5dd8f4
      Yinghai Lu authored
      On a system where system memory (according e820) is not covered by
      mtrr, mtrr_trim_memory converts a portion of memory to reserved, but
      bootloader has already put the initrd in that range.
      
      Thus, we need to have 64bit to use relocate_initrd too.
      
      [ Impact: fix using initrd when mtrr_trim_memory happen ]
