      ide: add ide_proc_register_port() · 5cbf79cd
      Bartlomiej Zolnierkiewicz authored
      * create_proc_ide_interfaces() tries to add /proc entries for every probed
        and initialized IDE port, replace it by ide_proc_register_port() which does
        it only for the given port (also rename destroy_proc_ide_interface() to
        ide_proc_unregister_port() for consistency)
        
      * convert {create,destroy}_proc_ide_interface[s]() users to use new functions
      
      * pmac driver depended on proc_ide_create() to add /proc port entries, fix it
        
      * au1xxx-ide, swarm and cs5520 drivers depended indirectly on ide-generic
        driver (CONFIG_IDE_GENERIC=y) to add port /proc entries, fix them
      
      * there is now no need to add /proc entries for IDE ports in proc_ide_create()
        so don't do it
      
      * proc_ide_create() needs now to be called before drivers are probed - fix it,
        while at it make proc_ide_create() create /proc "ide" directory

      ide: add "initializing" argument to ide_register_hw() · 869c56ee

      Add "initializing" argument to ide_register_hw() and use it instead of ide.c
      wide variable of the same name.  Update all users of ide_register_hw()
      accordingly.

      ide: cable detection fixes (take 2) · 7f8f48af
      Bartlomiej Zolnierkiewicz authored
      Tejun's recent eighty_ninty_three() fix has inspired me to do more thorough
      review of the cable detection code...
      
      * print user-friendly warning about limiting the maximum transfer speed
        to UDMA33 (and the reason behind it) when 80-wire cable is not detected,
        also while at it cleanup eighty_ninty_three() a bit
      
      * use eighty_ninty_three() in ide_ata66_check(), this actually fixes 3 bugs:
        - bit 14 (word 93 validity check) == 1 && bit 13 (80-wire cable test) == 1
          were used as 80-wire cable present test for CONFIG_IDEDMA_IVB=n case
          (please see FIXME comment in eighty_ninty_three() for more details)
        - CONFIG_IDEDMA_IVB=y/n cases were interchanged
        - check for SATA devices was missing
      
      * remove private cable warnings from pdc_202xx{old,new} drivers now that core
        code provides this functionality (plus, in pdc202xx_new case the test could
        give false warnings for ATAPI devices because pdc202xx_new driver doesn't
        even support ATAPI DMA)

      * remove bogus comment from ide.h
      
      * cover with CONFIG_IDE_PROC_FS #ifdef .proc and .settings in ide_drive_t
      
      Besides saner code this patch results in the IDE core smaller by ~2 kB
      (on x86-32) and IDE disk driver by ~1 kB (ditto) when CONFIG_IDE_PROC_FS=n.

      Bartlomiej Zolnierkiewicz authored
      Depends on the "ide: fix UDMA/MWDMA/SWDMA masks" patch.
      
      * add ide_hwif_t.udma_filter hook for filtering UDMA mask
        (use it in alim15x3, hpt366, siimage and serverworks drivers)
      * add ide_max_dma_mode() for finding best DMA mode for the device
        (loosely based on some older libata-core.c code)
      * convert ide_dma_speed() users to use ide_max_dma_mode()

        of "u8 mode" and teach it to how to use UDMA mask to do filtering
      * use ide_rate_filter() in hpt366 driver

      Documentation/i386/boot.txt: update and correct · de372ecd
      H. Peter Anvin authored
      In the process of rewriting the x86 setup code, I found a number of
      inaccuracies and outdated recommendations in the boot protocol
      documentation.  Revamp to make it more up to date.
      
      In particular, the common use of the heap actually requires (slightly)
      more than 4K of heap plus stack, which is the recommended amount in
      the document; currently the code compensates by being smaller than
      specified, but we can't assume that will be true forever.  Thus,
      recommend that if we have a modern bzImage kernel, that the bootloader
      maximizes the available space.

      revert 'sched: redundant reschedule when set_user_nice() boosts a prio of a task from the "expired" array'
      
      Revert commit bd53f96c.
      
      Con says:
      
      This is no good, sorry. The one I saw originally was with the staircase
      deadline cpu scheduler in situ and was different.
      
        #define TASK_PREEMPTS_CURR(p, rq) \
           ((p)->prio < (rq)->curr->prio)
           (((p)->prio < (rq)->curr->prio) && ((p)->array == (rq)->active))
      
      This will fail to wake up a runqueue for a task that has been migrated to the
      expired array of a runqueue which is otherwise idle which can happen with smp
      balancing,

       (2) Mark __frv_uart0 and __frv_uart1 __pminitdata rather than __initdata so
           that determine_clocks() can access them when CONFIG_PM=y.
      
       (3) Make arch/frv/mm/elf-fdpic.c include asm/mman.h so that MAP_FIXED is

      By the time kthread_run returns the param may have already been freed
      so writing the returned thread_struct pointer to param is wrong.
      
      In fact, we don't need it in param anyway so this patch simply puts it
      on the stack.
