      partitions/efi: loosen check fot pmbr size in lba · 6b02fa59
      Davidlohr Bueso authored
      Matt found that commit 27a7c642 ("partitions/efi: account for pmbr
      size in lba") caused his GPT formatted eMMC device not to boot.  The
      reason is that this commit enforced Linux to always check the lesser of
      the whole disk or 2Tib for the pMBR size in LBA.  While most disk
      partitioning tools out there create a pMBR with these characteristics,
      Microsoft does not, as it always sets the entry to the maximum 32-bit
      limitation - even though a drive may be smaller than that[1].
      Loosen this check and only verify that the size is either the whole disk
      or 0xFFFFFFFF.  No tool in its right mind would set it to any value
      other than these.

      cifs: Avoid calling unlock_page() twice in cifs_readpage() when using fscache · 466bd31b
      Sachin Prabhu authored
      When reading a single page with cifs_readpage(), we make a call to
      fscache_read_or_alloc_page() which once done, asynchronously calls
      the completion function cifs_readpage_from_fscache_complete(). This
      completion function unlocks the page once it has been populated from
      cache. The module then attempts to unlock the page a second time in
      cifs_readpage() which leads to warning messages.
      In case of a successful call to fscache_read_or_alloc_page() we should skip
      the second unlock_page() since this will be called by the
      cifs_readpage_from_fscache_complete() once the page has been populated by
      With the modifications to cifs_readpage_worker(), we will need to re-grab the
      page lock in cifs_write_begin().
      The problem was first noticed when testing new fscache patches for cifs.

      MIPS: DECstation I/O ASIC DMA interrupt handling fix · 5359b938
      Maciej W. Rozycki authored
      This change complements commit d0da7c002f7b2a93582187a9e3f73891a01d8ee4
      and brings clear_ioasic_irq back, renaming it to clear_ioasic_dma_irq at
      the same time, to make I/O ASIC DMA interrupts functional.
      Unlike ordinary I/O ASIC interrupts DMA interrupts need to be deasserted
      by software by writing 0 to the respective bit in I/O ASIC's System
      Interrupt Register (SIR), similarly to how CP0.Cause.IP0 and CP0.Cause.IP1
      bits are handled in the CPU (the difference is SIR DMA interrupt bits are
      R/W0C so there's no need for an RMW cycle).  Otherwise the handler is
      reentered over and over again.
      The only current user is the DEC LANCE Ethernet driver and its extremely
      uncommon DMA memory error handler that does not care when exactly the
      interrupt is cleared.  Anticipating the use of DMA interrupts by the Zilog
      SCC driver this change however exports clear_ioasic_dma_irq for device
      drivers to choose the right application-specific sequence to clear the
      request explicitly rather than calling it implicitly in the .irq_eoi
      handler of `struct irq_chip'.  Previously these interrupts were cleared in
      the .end handler of the said structure, before it was removed.

      MIPS: DECstation HRT initialization rearrangement · daed1285
      Maciej W. Rozycki authored
      Not all I/O ASIC versions have the free-running counter implemented, an
      early revision used in the 5000/1xx models aka 3MIN and 4MIN did not have
      it.  Therefore we cannot unconditionally use it as a clock source.
      Fortunately if not implemented its register slot has a fixed value so it
      is enough if we check for the value at the end of the calibration period
      being the same as at the beginning.
      This also means we need to look for another high-precision clock source on
      the systems affected.  The 5000/1xx can have an R4000SC processor
      installed where the CP0 Count register can be used as a clock source.
      Unfortunately all the R4k DECstations suffer from the missed timer
      interrupt on CP0 Count reads erratum, so we cannot use the CP0 timer as a
      clock source and a clock event both at a time.  However we never need an
      R4k clock event device because all DECstations have a DS1287A RTC chip
      whose periodic interrupt can be used as a clock source.
      This gives us the following four configuration possibilities for I/O ASIC
      1. No I/O ASIC counter and no CP0 timer, e.g. R3k 5000/1xx (3MIN).
      2. No I/O ASIC counter but the CP0 timer, i.e. R4k 5000/150 (4MIN).
      3. The I/O ASIC counter but no CP0 timer, e.g. R3k 5000/240 (3MAX+).
      4. The I/O ASIC counter and the CP0 timer, e.g. R4k 5000/260 (4MAX+).
      For #1 and #2 this change stops the I/O ASIC free-running counter from
      being installed as a clock source of a 0Hz frequency.  For #2 it also
      arranges for the CP0 timer to be used as a clock source rather than a
      clock event device, because having an accurate wall clock is more
      important than a high-precision interval timer.  For #3 there is no
      change.  For #4 the change makes the I/O ASIC free-running counter
      installed as a clock source so that the CP0 timer can be used as a clock
      event device.
      Unfortunately the use of the CP0 timer as a clock event device relies on a
      succesful completion of c0_compare_interrupt.  That never happens, because
      while waiting for a CP0 Compare interrupt to happen the function spins in
      a loop reading the CP0 Count register.  This makes the CP0 Count erratum
      trigger reliably causing the interrupt waited for to be lost in all cases.
      As a result #4 resorts to using the CP0 timer as a clock source as well,
      just as #2
      .  However we want to keep this separate arrangement in case
      (hope) c0_compare_interrupt is eventually rewritten such that it avoids
      the erratum.
