      libata: honour host controllers that want just one host · dc87c398
      Linus Torvalds authored
      The Marvell IDE interface on my machine would hit a BUG_ON() in
      lib/iomem.c because it was calling ata_pci_init_one() specifying just a
      single port on the host, but that would actually end up trying to
      initialize two ports, the second one with bogus information.
      
      This fixes "ata_pci_init_one()" so that it actually passes down the
      n_ports variable that it got from the low-level driver to the host
      allocation routine ("ata_host_alloc_pinfo()"), which results in the ATA
      layer actually having the correct port number information.
      
      And in order to make it all work, I also needed to fix a few places that
      had incorrectly hard-coded the fact that a host always had exactly two
      ports (both ata_pci_init_bmdma() and ata_request_legacy_irqs() would
      just always iterate over both ports).

      pm: include EIO from errno-base.h · 14e38ac8
      David Rientjes authored
      For backwards compatibility, call_platform_enable_wakeup() can return 0
      instead of -EIO since we aren't guaranteed to have errno defined.

      power management: force pm_ops.valid callback to be assigned · 9684e51c
      Johannes Berg authored
      This patch changes the docs and behaviour from "all states valid" to "no
      states valid" if no .valid callback is assigned.  Users of pm_ops that only
      need mem sleep can assign pm_valid_only_mem without any overhead, others
      will require more elaborate callbacks.
      
      Now that all users of pm_ops have a .valid callback this is a safe thing to
      do and prevents things from getting messy again as they were before.

      power management: implement pm_ops.valid for everybody · e8c9c502
      Johannes Berg authored
      Almost all users of pm_ops only support mem sleep, don't check in .valid and
      don't reject any others in .prepare so users can be confused if they check
      /sys/power/state, especially when new states are added (these would then
      result in s-t-r although they're supposed to be something different).
      
      This patch implements a generic pm_valid_only_mem function that is then
      exported for users and puts it to use in almost all existing pm_ops.

      rework pm_ops pm_disk_mode, kill misuse · fe0c935a
      Johannes Berg authored
      This patch series cleans up some misconceptions about pm_ops.  Some users of
      the pm_ops structure attempt to use it to stop the user from entering suspend
      to disk, this, however, is not possible since the user can always use
      "shutdown" in /sys/power/disk and then the pm_ops are never invoked.  Also,
      platforms that don't support suspend to disk simply should not allow
      configuring SOFTWARE_SUSPEND (read the help text on it, it only selects
      suspend to disk and nothing else, all the other stuff depends on PM).
      
      The pm_ops structure is actually intended to provide a way to enter
      platform-defined sleep states (currently supported states are "standby" and
      "mem" (suspend to ram)) and additionally (if SOFTWARE_SUSPEND is configured)
      allows a platform to support a platform specific way to enter low-power mode
      once everything has been saved to disk.  This is currently only used by ACPI
      (S4).
      
      This patch:
      
      The pm_ops.pm_disk_mode is used in totally bogus ways since nobody really
      seems to understand what it actually does.
      
      This patch clarifies the pm_disk_mode description.
      
      It also removes all the arm and sh users that think they can veto suspend to
      disk via pm_ops; not so since the user can always do echo shutdown >
      /sys/power/disk, they need to find a better way involving Kconfig or such.
      
      ACPI is the only user left with a non-zero pm_disk_mode.
      
      The patch also sets the default mode to shutdown again, but when a new pm_ops
      is registered its pm_disk_mode is selected as default, that way the default
      stays for ACPI where it is apparently required.

      Extend print_symbol capability · 42e38083
      Robert Peterson authored
      Today's print_symbol function dumps a kernel symbol with printk.  This
      patch extends the functionality of kallsyms.c so that the symbol lookup
      function may be used without the printk.  This is useful for modules that
      want to dump symbols elsewhere, for example, to debugfs.  I intend to use
      the new function call in the GFS2 file system (which will be a separate
      patch).
