      PCI: Cleanup the includes of <linux/pci.h> · 6473d160
      Jean Delvare authored
      I noticed that many source files include <linux/pci.h> while they do
      not appear to need it. Here is an attempt to clean it all up.
      
      In order to find all possibly affected files, I searched for all
      files including <linux/pci.h> but without any other occurence of "pci"
      or "PCI". I removed the include statement from all of these, then I
      compiled an allmodconfig kernel on both i386 and x86_64 and fixed the
      false positives manually.
      
      My tests covered 66% of the affected files, so there could be false
      positives remaining. Untested files are:
      
      arch/alpha/kernel/err_common.c
      arch/alpha/kernel/err_ev6.c
      arch/alpha/kernel/err_ev7.c
      arch/ia64/sn/kernel/huberror.c
      arch/ia64/sn/kernel/xpnet.c
      arch/m68knommu/kernel/dma.c
      arch/mips/lib/iomap.c
      arch/powerpc/platforms/pseries/ras.c
      arch/ppc/8260_io/enet.c
      arch/ppc/8260_io/fcc_enet.c
      arch/ppc/8xx_io/enet.c
      arch/ppc/syslib/ppc4xx_sgdma.c
      arch/sh64/mach-cayman/iomap.c
      arch/xtensa/kernel/xtensa_ksyms.c

      drivers/misc/hdpuftrs/hdpu_cpustate.c
      drivers/misc/hdpuftrs/hdpu_nexus.c
      drivers/net/au1000_eth.c
      drivers/net/fec_8xx/fec_main.c
      drivers/net/fec_8xx/fec_mii.c

      include/asm-arm/arch-ixp4xx/dma.h
      sound/oss/au1550_ac97.c
      
      I would welcome test reports for these files. I am fine with removing
      the untested files from the patch if the general opinion is that these
      changes aren't safe. The tested part would still be nice to have.
      
      Note that this patch depends on another header fixup patch I submitted
      to LKML yesterday:
        [PATCH] scatterlist.h needs types.h

      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.
