      parisc: move definition of PAGE0 to asm/page.h · 4a8a0788
      Rolf Eike Beer 提交于
      This was defined in asm/pdc.h which needs to include asm/page.h for
      __PAGE_OFFSET. This leads to an include loop so that page.h eventually will
      include pdc.h again. While this is no problem because of header guards, it is
      a problem because some symbols may be undefined. Such an error is this:

      xen/pte: Fix crashes when trying to see non-existent PGD/PMD/PUD/PTEs · b7e5ffe5
      Konrad Rzeszutek Wilk 提交于
      If I try to do "cat /sys/kernel/debug/kernel_page_tables"
      I end up with:
      
      BUG: unable to handle kernel paging request at ffffc7fffffff000
      IP: [<ffffffff8106aa51>] ptdump_show+0x221/0x480
      PGD 0
      Oops: 0000 [#1] SMP
      CPU 0
      .. snip..
      RAX: 0000000000000000 RBX: ffffc00000000fff RCX: 0000000000000000
      RDX: 0000800000000000 RSI: 0000000000000000 RDI: ffffc7fffffff000
      
      which is due to the fact we are trying to access a PFN that is not
      accessible to us. The reason (at least in this case) was that
      PGD[256] is set to __HYPERVISOR_VIRT_START which was setup (by the
      hypervisor) to point to a read-only linear map of the MFN->PFN array.
      During our parsing we would get the MFN (a valid one), try to look
      it up in the MFN->PFN tree and find it invalid and return ~0 as PFN.
      Then pte_mfn_to_pfn would happilly feed that in, attach the flags
      and return it back to the caller. 'ptdump_show' bitshifts it and
      gets and invalid value that it tries to dereference.
      
      Instead of doing all of that, we detect the ~0 case and just
      return !_PAGE_PRESENT.
      
      This bug has been in existence .. at least until 2.6.37 (yikes!)

      xen/apic: Return the APIC ID (and version) for CPU 0. · 558daa28
      Konrad Rzeszutek Wilk 提交于
      On x86_64 on AMD machines where the first APIC_ID is not zero, we get:
      
      ACPI: LAPIC (acpi_id[0x01] lapic_id[0x10] enabled)
      BIOS bug: APIC version is 0 for CPU 1/0x10, fixing up to 0x10
      BIOS bug: APIC version mismatch, boot CPU: 0, CPU 1: version 10
      
      which means that when the ACPI processor driver loads and
      tries to parse the _Pxx states it fails to do as, as it
      ends up calling acpi_get_cpuid which does this:
      
      for_each_possible_cpu(i) {
              if (cpu_physical_id(i) == apic_id)
                      return i;
      }
      
      And the bootup CPU, has not been found so it fails and returns -1
      for the first CPU - which then subsequently in the loop that
      "acpi_processor_get_info" does results in returning an error, which
      means that "acpi_processor_add" failing and per_cpu(processor)
      is never set (and is NULL).
      
      That means that when xen-acpi-processor tries to load (much much
      later on) and parse the P-states it gets -ENODEV from
      acpi_processor_register_performance() (which tries to read
      the per_cpu(processor)) and fails to parse the data.

      It turns out that (quite surprisingly) devres_destroy() only undoes the
      devres mapping, it doesn't destroy the underlying resource, meaning that
      anything using devm_regulator_put() would leak. While we wait for the new
