      samsung-laptop: Disable on EFI hardware · e0094244
      Matt Fleming authored
      It has been reported that running this driver on some Samsung laptops
      with EFI can cause those machines to become bricked as detailed in the
      following report,
      
      	https://bugs.launchpad.net/ubuntu-cdimage/+bug/1040557
      
      There have also been reports of this driver causing Machine Check
      Exceptions on recent EFI-enabled Samsung laptops,
      
      	https://bugzilla.kernel.org/show_bug.cgi?id=47121
      
      So disable it if booting from EFI since this driver relies on
      grovelling around in the BIOS memory map which isn't going to work.

      efi: Make 'efi_enabled' a function to query EFI facilities · 83e68189
      Matt Fleming authored
      Originally 'efi_enabled' indicated whether a kernel was booted from
      EFI firmware. Over time its semantics have changed, and it now
      indicates whether or not we are booted on an EFI machine with
      bit-native firmware, e.g. 64-bit kernel with 64-bit firmware.
      
      The immediate motivation for this patch is the bug report at,
      
          https://bugs.launchpad.net/ubuntu-cdimage/+bug/1040557
      
      which details how running a platform driver on an EFI machine that is
      designed to run under BIOS can cause the machine to become
      bricked. Also, the following report,
      
          https://bugzilla.kernel.org/show_bug.cgi?id=47121
      
      details how running said driver can also cause Machine Check
      Exceptions. Drivers need a new means of detecting whether they're
      running on an EFI machine, as sadly the expression,
      
          if (!efi_enabled)
      
      hasn't been a sufficient condition for quite some time.
      
      Users actually want to query 'efi_enabled' for different reasons -
      what they really want access to is the list of available EFI
      facilities.
      
      For instance, the x86 reboot code needs to know whether it can invoke
      the ResetSystem() function provided by the EFI runtime services, while
      the ACPI OSL code wants to know whether the EFI config tables were
      mapped successfully. There are also checks in some of the platform
      driver code to simply see if they're running on an EFI machine (which
      would make it a bad idea to do BIOS-y things).
      
      This patch is a prereq for the samsung-laptop fix patch.

      powerpc: Max next_tb to prevent from replaying timer interrupt · 689dfa89
      Tiejun Chen authored
      With lazy interrupt, we always call __check_irq_replaysome with
      decrementers_next_tb to check if we need to replay timer interrupt.
      So in hotplug case we also need to set decrementers_next_tb as MAX
      to make sure __check_irq_replay don't replay timer interrupt
      when return as we expect, otherwise we'll trap here infinitely.

      The calculation for the left shift of the mask OPROFILE_PM_PMCSEL_MSK has an
      error.  The calculation is should be to shift left by (max_cntrs - cntr) times
      the width of the pmsel field width.  However, the #define OPROFILE_MAX_PMC_NUM
      was used instead of OPROFILE_PMSEL_FIELD_WIDTH.  This patch fixes the

      powerpc/pasemi: Fix crash on reboot · 72640d88
      Steven Rostedt authored
      commit f96972f2 "kernel/sys.c: call disable_nonboot_cpus() in
      kernel_restart()"
      
      added a call to disable_nonboot_cpus() on kernel_restart(), which tries
      to shutdown all the CPUs except the first one. The issue with the PA
      Semi, is that it does not support CPU hotplug.
      
      When the call is made to __cpu_down(), it calls the notifiers
      CPU_DOWN_PREPARE, and then tries to take the CPU down.
      
      One of the notifiers to the CPU hotplug code, is the cpufreq. The
      DOWN_PREPARE will call __cpufreq_remove_dev() which calls
      cpufreq_driver->exit. The PA Semi exit handler unmaps regions of I/O
      that is used by an interrupt that goes off constantly
      (system_reset_common, but it goes off during normal system operations
      too). I'm not sure exactly what this interrupt does.
      
      Running a simple function trace, you can see it goes off quite a bit:
      
      # tracer: function
      #
      #           TASK-PID    CPU#    TIMESTAMP  FUNCTION

      When the region is unmapped, the system crashes with:

        dmraid assess redundancy and replacements slightly inaccurately which

      xfs: Fix xfs_swap_extents() after removal of xfs_flushinval_pages() · 65e3aa77
      Torsten Kaiser authored
      Commit fb595814 removed
      xfs_flushinval_pages() and changed its callers to use
      filemap_write_and_wait() and  truncate_pagecache_range() directly.
      
      But in xfs_swap_extents() this change accidental switched the argument
      for 'tip' to 'ip'. This patch switches it back to 'tip'

       "This is the first pull request for MFD fixes for 3.8
      
        We have some build failure fixes (twl4030, vexpress, abx500 and
        tps65910), some actual runtime oops and lockup fixes (rtsx, da9052),
        and some more hypothetical NULL pointers dereferences fixes for
        pcf50633 and max776xx.
      
        Then we also have additional rtsx fixes for a correct switch output
        voltage and clock divider correctness for rtl8411 (rtsx driver), and
        irqdomain fix for db8550-prcmu, and some more cosmetic fixes for
