      ACPI: Evaluate thermal trip points before reading temperature · 9bcb8118
      Matthew Garrett authored
      An HP laptop (Pavilion G4-1016tx) has the following code in _TMP:
      
             Store (\_SB.PCI0.LPCB.EC0.RTMP, Local0)
             If (LGreaterEqual (Local0, S4TP))
             {
                 Store (One, HTS4)
             }
      
      S4TP is initialised at 0 and not programmed further until either _HOT or
      _CRT is called. If we evaluate _TMP before the trip points then HTS4 will
      always be set, causing the firmware to generate a message on boot
      complaining that the system shut down because of overheating. The simplest
      solution is just to reverse the checking of trip points and _TMP in thermal
      init.

      include cleanup: Update gfp.h and slab.h includes to prepare for breaking implicit slab.h inclusion from percpu.h
      
      percpu.h is included by sched.h and module.h and thus ends up being
      included when building most .c files.  percpu.h includes slab.h which
      in turn includes gfp.h making everything defined by the two files
      universally available and complicating inclusion dependencies.
      
      percpu.h -> slab.h dependency is about to be removed.  Prepare for
      this change by updating users of gfp and slab facilities include those
      headers directly instead of assuming availability.  As this conversion
      needs to touch large number of source files, the following script is
      used as the basis of conversion.
      
        http://userweb.kernel.org/~tj/misc/slabh-sweep.py
      
      The script does the followings.
      
      * Scan files for gfp and slab usages and update includes such that
        only the necessary includes are there.  ie. if only gfp is used,
        gfp.h, if slab is used, slab.h.
      
      * When the script inserts a new include, it looks at the include
        blocks and try to put the new include such that its order conforms
        to its surrounding.  It's put in the include block which contains
        core kernel includes, in the same order that the rest are ordered -
        alphabetical, Christmas tree, rev-Xmas-tree or at the end if there
        doesn't seem to be any matching order.
      
      * If the script can't find a place to put a new include (mostly
        because the file doesn't have fitting include block), it prints out
        an error message indicating which .h file needs to be added to the
        file.
      
      The conversion was done in the following steps.
      
      1. The initial automatic conversion of all .c files updated slightly
         over 4000 files, deleting around 700 includes and adding ~480 gfp.h
         and ~3000 slab.h inclusions.  The script emitted errors for ~400
         files.
      
      2. Each error was manually checked.  Some didn't need the inclusion,
         some needed manual addition while adding it to implementation .h or
         embedding .c file was more appropriate for others.  This step added
         inclusions to around 150 files.
      
      3. The script was run again and the output was compared to the edits
         from #2 to make sure no file was left behind.
      
      4. Several build tests were done and a couple of problems were fixed.
         e.g. lib/decompress_*.c used malloc/free() wrappers around slab
         APIs requiring slab.h to be added manually.
      
      5. The script was run on all .h files but without automatically
         editing them as sprinkling gfp.h and slab.h inclusions around .h
         files could easily lead to inclusion dependency hell.  Most gfp.h
         inclusion directives were ignored as stuff from gfp.h was usually
         wildly available and often used in preprocessor macros.  Each
         slab.h inclusion directive was examined and added manually as
         necessary.
      
      6. percpu.h was updated not to include slab.h.
      
      7. Build test were done on the following configurations and failures
         were fixed.  CONFIG_GCOV_KERNEL was turned off for all tests (as my
         distributed build env didn't work with gcov compiles) and a few
         more options had to be turned off depending on archs to make things
         build (like ipr on powerpc/64 which failed due to missing writeq).
      
         * x86 and x86_64 UP and SMP allmodconfig and a custom test config.
         * powerpc and powerpc64 SMP allmodconfig
         * sparc and sparc64 SMP allmodconfig
         * ia64 SMP allmodconfig
         * s390 SMP allmodconfig
         * alpha SMP allmodconfig
         * um on x86_64 SMP allmodconfig
      
      8. percpu.h modifications were reverted so that it could be applied as
         a separate patch and serve as bisection point.
      
      Given the fact that I had only a couple of failures from tests on step
      6, I'm fairly confident about the coverage of this conversion patch.
      If there is a breakage, it's likely to be something in one of the arch
      headers which should be easily discoverable easily on most builds of
      the specific arch.

      proc 2/2: remove struct proc_dir_entry::owner · 99b76233
      Alexey Dobriyan authored
      Setting ->owner as done currently (pde->owner = THIS_MODULE) is racy
      as correctly noted at bug #12454. Someone can lookup entry with NULL
      ->owner, thus not pinning enything, and release it later resulting
      in module refcount underflow.
      
      We can keep ->owner and supply it at registration time like ->proc_fops
      and ->data.
      
      But this leaves ->owner as easy-manipulative field (just one C assignment)
      and somebody will forget to unpin previous/pin current module when
      switching ->owner. ->proc_fops is declared as "const" which should give
      some thoughts.
      
      ->read_proc/->write_proc were just fixed to not require ->owner for
      protection.
      
      rmmod'ed directories will be empty and return "." and ".." -- no harm.
      And directories with tricky enough readdir and lookup shouldn't be modular.
      We definitely don't want such modular code.
      
      Removing ->owner will also make PDE smaller.
      
      So, let's nuke it.
      
      Kudos to Jeff Layton for reminding about this, let's say, oversight.

      ACPI: struct device - replace bus_id with dev_name(), dev_set_name() · 0794469d
      Kay Sievers authored
      This patch is part of a larger patch series which will remove
      the "char bus_id[20]" name string from struct device. The device
      name is managed in the kobject anyway, and without any size
      limitation, and just needlessly copied into "struct device".
      
      To set and read the device name dev_name(dev) and dev_set_name(dev)
      must be used. If your code uses static kobjects, which it shouldn't
      do, "const char *init_name" can be used to statically provide the
      name the registered device should have. At registration time, the
      init_name field is cleared, to enforce the use of dev_name(dev) to
      access the device name at a later time.
      
      We need to get rid of all occurrences of bus_id in the entire tree
      to be able to enable the new interface. Please apply this patch,
      and possibly convert any remaining remaining occurrences of bus_id.
      
      We want to submit a patch to -next, which will remove bus_id from
      "struct device", to find the remaining pieces to convert, and finally
      switch over to the new api, which will remove the 20 bytes array
      and does no longer have a size limitation.

      ACPI: replace ACPI_DEBUG_PRINT((ACPI_DB_ERROR, ...) with printk · 55ac9a01
      Lin Ming authored
      ACPI_DB_ERROR and ACPI_DB_WARN were removed from ACPICA core.
      So replace ACPI_DEBUG_PRINT((ACPI_DB_ERROR, ...) with printk(KERN_ERR PREFIX ...)
      and ACPI_DEBUG_PRINT((ACPI_DB_WARN, ...) with printk(KERN_WARNING PREFIX ...)
      
      We do not use ACPI_ERROR/ACPI_WARNING since they're not exported, see
