      This cleanup series gets rid of <mach/timex.h> for platforms not using
      ARCH_MULTIPLATFORM. (For multi-platform code it's already unused since
      387798b3 (ARM: initial multiplatform support).)
      
      To make this work some code out of arch/arm needed to be adapted. The
      respective changes got acks by their maintainers to be taken via armsoc
      (with Andrew Morton substituting for Alessandro Zummo as rtc maintainer).
      
      Compared to the previous pull request there was another patch added that
      fixes a (non-critical) regression on ixp4xx. Olof Johansson asked to not
      squash this fix into the original commit to save him from the need to
      reverify the series.

      ARM: efm32: drop selecting CLKSRC_MMIO · a00dfedd
      Uwe Kleine-König authored
      CLKSRC_MMIO is needed on efm32 because the clocksource driver
      (CLKSRC_EFM32) uses clocksource_mmio_init() and
      clocksource_mmio_readl_up(). Since commit 09ca2757 (clocksource:
      time-efm32: Select CLKSRC_MMIO) CLKSRC_EFM32 does the necessary select
      itself and ARCH_EFM32 doesn't need to select it explicitly any more.

      ARM: ixp4xx: fix timer latch calculation · fb3174e4
      Uwe Kleine-König authored
      In commit f0402f9b ("ARM: ixp4xx: stop using <mach/timex.h>")
      I didn't intend to implement a functional change, but as Olof noticed I
      failed---at least a bit. Before this commit the following was used to
      determine the latch value used:
      
      	#define IXP4XX_TIMER_FREQ 66666000
      	#define CLOCK_TICK_RATE \
      		(((IXP4XX_TIMER_FREQ / HZ & ~IXP4XX_OST_RELOAD_MASK) + 1) * HZ)
      	#define LATCH ((CLOCK_TICK_RATE + HZ/2) / HZ)
      
      The complicated calculation was done "b/c the timer register ignores the
      bottom 2 bits of the LATCH value." With HZ=100 CLOCK_TICK_RATE used to
      calculate to 66666100 and so LATCH to 666661. In ixp4xx_set_mode the
      term
      
      	LATCH & ~IXP4XX_OST_RELOAD_MASK
      
      was used to write to the relevant register (with IXP4XX_OST_RELOAD_MASK
      being 3) and so effectively 666660 was used.
      
      In commit f0402f9b I translated that to:
      
      	#define IXP4XX_TIMER_FREQ 66666000
      	#define IXP4XX_LATCH DIV_ROUND_CLOSEST(IXP4XX_TIMER_FREQ, HZ)
      
      which results in the same register writes, but still doesn't bear in
      mind that the two least significant bits cannot be specified (which is
      relevant only when HZ or IXP4XX_TIMER_FREQ are changed).
      
      Instead of reverting back to the old approach use a more obvious and
      also more correct way to calculate LATCH. (Regarding the more
      correct claim: With IXP4XX_TIMER_FREQ == 66665999, the old code resulted
      in LATCH = 666657 corresponding to a cycle time of 0.009999940149400597
      seconds (error: -6.0e-8 s) while the new approach results in LATCH =
      666660 and so a cycle time of 0.010000000150001503 seconds
      (error: 1.5e-10 s).)

      Pull parisc updates from Helge Deller:
       "The three major changes in this patchset is a implementation for

        long-discussed ABI change to make EWOULDBLOCK the same value as
        EAGAIN.
      
        parisc has been the only platform where we had EWOULDBLOCK != EAGAIN
        to keep HP-UX compatibility.  Since we will probably never implement
        full HP-UX support, we prefer to drop this compatibility to make it
        easier for us with Linux userspace programs which mostly never checked
        for both values.  We don't expect major fall-outs because of this
        change, and if we face some, we will simply rebuild the necessary
        applications in the debian archives"

      hpfs: optimize quad buffer loading · 1c0b8a7a
      Mikulas Patocka authored
      HPFS needs to load 4 consecutive 512-byte sectors when accessing the
      directory nodes or bitmaps.  We can't switch to 2048-byte block size
      because files are allocated in the units of 512-byte sectors.
      
      Previously, the driver would allocate a 2048-byte area using kmalloc,
      copy the data from four buffers to this area and eventually copy them
      back if they were modified.
      
      In the current implementation of the buffer cache, buffers are allocated
      in the pagecache.  That means that 4 consecutive 512-byte buffers are
      stored in consecutive areas in the kernel address space.  So, we don't
      need to allocate extra memory and copy the content of the buffers there.
      
      This patch optimizes the code to avoid copying the buffers.  It checks
      if the four buffers are stored in contiguous memory - if they are not,
      it falls back to allocating a 2048-byte area and copying data there.

      hpfs: remember free space · 2cbe5c76
      Mikulas Patocka authored
      Previously, hpfs scanned all bitmaps each time the user asked for free
      space using statfs.  This patch changes it so that hpfs scans the
      bitmaps only once, remembes the free space and on next invocation of
      statfs it returns the value instantly.
      
      New versions of wine are hammering on the statfs syscall very heavily,
      making some games unplayable when they're stored on hpfs, with load
      times in minutes.
      
      This should be backported to the stable kernels because it fixes
      user-visible problem (excessive level load times in wine).
